Automatically updating to the release or test versions of Acorn

Acorn 5 6 5 – Bitmap Image Editor Free

Auto-update to test releases (newest, super fun development releases)
Auto-update to regular releases (boring old production releases)
.
    Fixes
  • Fixed UI issues when swapping between dark and light aqua in the add filter sheet.
  • Fixed a problem that cropped up sometimes when loading PDF files.
  • Fixed a problem where an invalid custom stroke dash setting could cause the stroke to not be drawn at all.
September 25th, 2020.
    Fixes
  • Compatibility fixes with MacOS 11 Big Sur.
  • Fixed a rare crasher when editing text with the Typography palette open and replacing selected text where the font had alternate glyphs available (but unused!) in the 'Glyph Variant' section of the Typography palette. This may come as a surprise, but it took a long time to figure out what exactly was causing this crash.
  • Fixed an issue where rotating the canvas could cause certainly sized bitmap layers to move off canvas.
  • Fixed an issue where the canvas rulers might show the wrong units scale or draw mirrored when you changed the origin (via the General Preferences).
  • Fixed an issue where dragging an image from Preview's sidebar would sometimes report it coming in as a TIFF file, when it was actually a PDF file. Thanks for that fun debugging session, Preview. It was a hoot.
  • Fixed an issue where drawing with the pixel tool might not draw on new areas of the canvas after resizing it to make it bigger.
June 17th, 2020.
    New
  • Pressing the 'c' key while the canvas color loupe is up will copy the current color as a HTML hex color to the clipboard. To bring up the loupe, press Control-C, or hold down the option key while using a brushing tool.
    Fixes
  • Cleaned up a problem where the wrong move cursor was showing up on the canvas.
May 27th, 2020.
    New Shape Processor Filters
  • Hue Shift. Shift the hue of your shapes by a configurable amount. (Available for MacOS 10.13 or later).
  • Flip. You can flip your shapes vertical or horizontal, using the flip axis of either the canvas, processed shapes, or the shape itself.
  • Fill, which lets you change the color a shape fills with (and if it fills at all).
  • Stroke, which lets you change if a shape draws a stroke, how wide it is, and the color.
  • Blend Mode, which will change the blend / compositing mode for all processed shapes.
  • And finally, if you double click on the canvas when Shape Processors are active, it will now bring up the Shape Processor palette.
    Other New Things
  • The Mask to Alpha filter has a new invert invert colors option. Normally mask to alpha will convert the black areas of your image to transparent, and the white to opaque (with gray somewhere in-between). With the new Invert Colors option, Mask to Alpha will now convert the white areas of your image to transparent, and keep the black opaque. This is great if you are scanning line line drawings from your own artwork, and want to make the backgrounds transparent.
    Minor Stuff
  • Acorn does a bit of database cleanup now by default when saving in the Acorn image format, which will result in smaller files in some cases.
  • Color profiles are now included with PSD exports (thanks to the folks at The Iconfactory for the patch!)
  • When resizing your image to something rather larger than normal, Acorn will ask to make sure that's what you wanted to do. (Acorn already did this for new documents, but it's super handy when resizing or changing your canvas size as well).
  • Improvements to PSD export.
  • Pasting an image into the New Image window will create a new image with the contents of the paste. This has always been the case. The new thing is that any open New Image windows will now close.
  • The Save Panel brought some old tricks back! If you Save a new image, or Save As… an existing image and enter the file name and type out a changed extension, Acorn will notice and auto-select the right file type from the format popup. This had been broken on 10.15 and sandboxed versions of Acorn previously. But no more! (Hat tip to Rich Siegel for the workaround).
  • The Edit ▸ Fill… command now picks the right fill color to use (instead of possibly the stroke) from the tool palette color well. (Also- in case you didn't already know, pressing Option-Delete will automatically fill a bitmap layer with the current fill color. It's a nice shortcut to have around).
  • Minor and mysterious QOL fixes involving fonts, color profile sheets, pixel tool drawing, and redrawing on 10.15.
  • Bezier shapes now draw their outlines and handles when manipulating anchor points and their associated handles.
  • Removed the 'Mix' filter.
    Fixes
  • Fixed a problem where the File ▸ Revert command might not set the canvas dimensions to the correct dimensions.
  • Fixed a problem where the text selection drawing would be pretty wonky if you had changed the line height of a text box.
  • Fixed a crasher where the OS would tell about non-existent color profiles, and then Acorn tried to use these ghost profiles.
  • Fixed some issues where applying a font to text where there are no valid glyphs would leave the font popup button in an interesting state.
  • Fixed a problem where the eraser tool might not restrict itself to selections.
  • Fixed a couple of little brushing issues with the tablet and blend modes.
  • Fixed a bunch of issues where SVG parsing would fail with complex paths. Also added support for the line-cap attribute when importing SVG files.
  • Fixed a problem when exporting all layers as SVG.
  • Fixed a problem where dragging SVG files onto the canvas wouldn't import the images correctly.
  • Fixed an issue with web export windows not displaying correctly for 16bpc images on 10.15.
  • Fixed an issue with the color picker not syncing up correctly on secondary displays.
  • Acorn now clamps the edges of a selection when a feather is being applied. This helps for when you take a selection with a feather and invert it, causing the edges to be feathered when that wasn't exactly expected.
November 20th, 2019.
    Fixes
  • Fixed a problem where 'Edit in Acorn' from Photos on 10.15 might not work.
  • Other minor 10.15 cleanups and fixes.
  • Fixed an issue when printing or exporting as PDF when some layers had non-normal blend modes.
  • Acorn is a little less aggressive about writing out extended attributes to remember things like the zoom scale between file opens.
  • Fixed a possible crasher in the brushing engine when using the smudge tool.
    Misc
  • New hidden pref to take layered screenshots without window shadows:
    defaults write com.flyingmeat.Acorn6 layeredScreenshotIgnoreShadow 1
October 17th, 2019.
    Fixes
  • Fixed an issue where the tool inspector would sometimes draw multiple inspectors at the same time.
  • Deep color compatibility fixes for MacOS 10.15 Catalina.
  • Fixed an issue where palettes wouldn't show up correctly on MacOS 10.15 Catalina if you had multiple displays connected.
October 7th, 2019.
    Fixes
  • Compatibility fixes for MacOS 10.15 Catalina.
  • Fixed a problem where transparent gradients on shape layer shapes weren't exporting as PDF correctly.
  • Fixed a crasher that could occur when trying to create an image from the FaceTime camera.
  • Fixed a problem where certain brushes weren't drawing in a straight line when you press the shift key while drawing.
  • Minor crop + bounds snapping fixes.
  • Fixed a problem where Acorn wasn't letting you enter math for the image resize fields.
  • Fixed a problem where Acorn wasn't loading unsigned plugins.
July 11th, 2019.
    New
  • The Clone tool now has an opacity option.
  • Crop improvements: You can now set the DPI of an image while cropping, and alignment guides now appear when rotating your image in a crop.
  • The Perspective Transform command has a new option in the palette to show / hide the grid. It also gets a new palette that shows up when invoked.
  • Feathering selections: The Select ▸ Feather… menu item has been removed and you can now control the feather on a selection right in the selection palette.
  • End caps for bezier paths: You can now change between round, square, and butt end cap styles for bezier paths. These new options are right under the join style in the path options section of the shape palette. Also, it's now easier to see the selected state of the line join and cap styles.
  • You can now use the anchor select tool to drag and select multiple anchors.
  • New Image Panel improvements: We've increased the accuracy when changing from one unit to another (ie- inches to centimeters) as well as added an option to view the resolution field as pixels per inch or pixels per centimeter.
  • The PDF import window now shows the pixel dimensions of what your new image will be (and updates accordingly when you change the DPI)
  • We've added a new advanced preference which tells Acorn to load 3rd party Image Units.
    Changes
  • New Polish Localization courtesy of Leszek Klich.
  • Better support for editing images from Bear.
  • Tightened up the pixel edges a shape will snap to on creation (specifically bezier path or rect shapes).
  • Adjust a text box to have a non-zero line height will no longer clip the top of the first line (for new text boxes only; existing text boxes will keep the old behavior).
  • The blinking insertion point for text boxes and paths is a little bit thicker now.
  • Kerning is now on by default for new text boxes (previously it was disabled). You can turn kerning off by editing and selecting the text, then using the Edit ▸ Font ▸ Kern ▸ Use None menu item. Additionally, the Command-Option-[ and Command-Option-] shortcuts can be used to tighten and loosen the kerning on selected text (while editing it).
  • Improvements to how the aspect ratio is kept when placing a crop preset on the canvas and then swapping the orientation with the 'x' key.
  • No longer showing a modal dialog box when a trying to change a locked layer. An in-canvas notification is now shown instead.
  • Web Export now lets you explicitly set the quality of your image when exporting, in addition to the already existing slider. The quality setting lets Acorn know how much compression to use when exporting your image.
  • The DPI for certain presets have been increased from 72 to 300 dpi.
  • Text padding changes. Prior to Acorn 6.5, text boxes had a 5 pixel inset which would make glyphs show up 5 pixels to the right of where the logical location of the text box was. This meant that when you left aligned a text box below a filled box, the starting glyph wasn't exactly where you'd expect it to be. In Acorn 6.5, new text boxes are created with a padding of 0 pixels so alignment will always happen as you'd expect. Existing text boxes keep the 5 pixel inset for compatibility's sake.
  • The default new document size has been changed to be whatever half the size of your display's pixel dimensions are.
  • Acorn has a new hidden pref for auto-saving of all file types, not just Acorn:
    defaults write com.flyingmeat.Acorn6 autosaveNonNativeImages 1
    If you're using this on lossy file types like JPEG, your image will degrade over time because each time you open and save your image, details are lost.
    Fixes
  • Fixed a problem where Smart Layer Export wouldn't work when an extension was not given in the file name.
  • Clearing the document edited state when using the Revert menu item.
  • Fixed a problem where adding a control point to the curves filter wouldn't show up right away.
  • Fixed a problem when using the pencil tool on 10.13 and later with the blend mode set to copy.
  • Fixed some little issues with Automator actions.
  • Fixed an issue where undo wouldn't always work when moving control points for a bezier path.
  • Better selections in text boxes when line and paragraph spacing are non-default values.
  • Fixed an issue where empty windows would sometimes come up when you launched Acorn.
  • Fixed a problem where setting the paragraph spacing to 0 while editing a text box would sometimes fail.
  • The File ▸ New from Selection command now copies over the correct DPI from the copied image.
  • Fixed an issue where the DPI of your image could change when using the Image ▸ Resize Image… menu item, and you didn't really want it to.
  • Fixed a problem where the Reselect command wouldn't work.
  • Fixed some issues when setting specific kerning on characters.
  • Fixed a problem when exporting an image as PDF when a shape layer had a layer filter turned on.
  • Fixed a possible memory leak when exporting via Web Export.
  • Fixed a minor bug where the cursor wouldn't update when you cleared a selection by pressing the ESC key.
April 16, 2019.
    Fixes
  • Fixed a problem where selections might show up when exporting as a rasterized PDF.
  • Fixed a problem where Acorn could (seemingly) randomly crash when moving selections.
  • Fixed a problem where Acorn could write a bad compressed PSD in certain cases.
March 6th, 2019.
    Fixes
  • Fixed a problem where instant alpha wasn't working on deep color images.
  • Fixed a problem where starting a new oval selection with the shift key down wouldn't make a circle selection right away.
    Hey did you know holding down the shift key when a selection is present will add to the current selection? And holding down the option key will remove from the selection. And holding both option and the shift key will perform a union to an existing selection.
  • Fixed a problem with the brush palette where you the softness slider was enabled for brushes which don't have a softness setting.
  • Fixed some problems making deep color images when running on 10.11.
January 14, 2019.
    Fixes
  • Fixed a bug when printing and a layer would come out smaller than expected.
  • Fixed PDF export bugs.
  • Improved color accuracy when using the Curves filter, and improvements when using it with 64 and 128 bit images.
January 4th, 2019.
    New Masking Things
  • Portrait Mask support! If you have an iPhone running iOS 12 which takes Portrait photos with the camera, Acorn will now detect and open up the Portrait Matte as a mask for the image! You can then enable this mask to block out the background and add fancy backgrounds or custom blurs for your image.
  • New menu item to move a layer mask to a regular layer. Select the layer with the mask, hold down the Shift and Option keys, and choose the Layer ▸ Eject Layer Mask menu item. This menu is also available under the action menu of the main palette window, and in the canvas contextual menu.
  • Drag and drop out layer masks! If you have a layer mask selected, you can now drag it out of the layers list into its own layer or even move it to another layer mask. Hold down the Shift key to move it to a layer that doesn't already have a layer mask. Hold down the option key to make a copy of it.
  • Hold down the shift key when clicking on a mask to toggle it on or off.
  • Did you know? You can hold down the option key when clicking on a mask to toggle direct visibility of it. A normal click on the layer mask again (or any other layer) will turn it off.
  • You can drag and drop a mask onto the trash icon to delete it.
  • You can drag and drop a mask onto the + icon to copy it.
  • When a mask is selected, pressing Command Delete will remove it.
  • Exporting layers will now export the mask as well (via the File ▸ Export ▸ Export All Layers… menu item). And you now have the option to apply the mask on export.
    New Brushing Things
  • Acorn has a brand new brushing engine with much improved performance when running on MacOS 10.13 or 10.14 Mojave.
  • A whole new category of 'Basic Round' brushes ranging from 1px in size up to 5000px.
  • Four new hand crafted bristle brushes.
  • Saved brushes now have an opacity setting that can go along with it.
  • The brush palette now has options for setting flow, softness, and the blending of the currently selected brush.
    Indexed PNG Images in Web Export
  • Reduce the number of images used for PNG export, and save in file size! When exporting as a PNG you now have the option to 'Index PNG Colors' which will reduce the bit depth of your image while also reducing the file size. Make an image that's 90% smaller than the original.
    Improved PDF Export
  • Instead of rasterizing everything to a single bitmap layer which is then turned into a vector-less PDF, Acorn will now mix vector layers with bitmap layers. What this means is that you can have a fancy background imported from somewhere, and have text on a path (or circle) and other shapes that aren't turned into bitmaps which can look bad at lower resolutions. What you get now is a PDF that can be zoomed in and scaled, and all your shape layers will retain their sharp edges. This does mean that shape layers don't get to have filters on them though. Which is a bummer, but we think it's worth the tradeoff. Some blend modes are also not supported. But, we've got this instance covered with the next bullet point. Which is the next line below. Please read on.
  • New 'PDF (Rasterized)' option when exporting, enabled by holding down the option key when clicking on the options popup. This is the old behavior, where a bitmap image is created from your canvas and then stuffed into a PDF.
    New Things
  • Improved speed with 64 bit images on MacOS 10.14 Mojave!
  • Now using visual effect views in the palettes, which lets the background color bleed in. However, if you have 'Reduct transparency' turned on in the Accessibility System Prefs, then we'll skip the whole background bleeding in thing.
    More Stuff
  • Improved accuracy with the Curves filter.
  • More precision when picking out colors on Retina displays with the canvas color loupe.
  • Various MacOS Mojave UI fixes.
  • Fixed a problem where web export of images with a layer which has a blend mode of Soft Light gives a preview that doesn't match the canvas.
  • Fixed a problem where Acorn could quit unexpectedly when cropping an image.
  • Fixed a problem where you couldn't control-click on a ruler to bring up the units contextual menu.
  • Fixed a problem when using the Share menu in other applications to send very large images to Acorn.
November 9, 2018.
    Changes
  • Just a super small update to fix some registration things.
October 6th, 2018.
    Fixes
  • Various MacOS Mojave 10.14 compatibility fixes.
  • Fixed a selection problem for OS X El Capitan 10.11.
  • Fixed various palette drawing issues.
  • Fixed a problem where some images would become corrupt when rotating them.
  • Command-clicking a layer mask's thumbnail now makes a correct selection out of the mask (previously it was inverted).
September 27th, 2018.
    Fixes
  • Various MacOS Mojave 10.14 compatibility fixes.
  • Fixed a problem where the brush designer couldn't open on 10.11.
  • Fixed an issue where the star and rect toolbar icons were swapped on 1x displays.

The One About Dark Mode and MacOS Mojave

Acorn is embracing the dark side. At least if you want it to- otherwise Acorn will totally pretend that Dark Mode doesn't exist and we're all good.

A new appearance requires new icons as well. We've refreshed all the icons in the welcome window as well as in the tools palette. And everyone gets those, not just folks running Mojave.

    Little New Things
  • New Appearance preference when running on Mojave: Pick either Dark Aqua, Aqua, or System to follow the system setting.
  • The Rotate shape processor now has a cumulative option.
  • The text palette now has a fill option right above the stroke field. Hurray- no more moving to the shape palette to turn strokes on and off!
    Changes
  • Improvements to zooming your image in and out with the ⌘-1 through 5 shortcut keys.
  • Better integration when editing from Photos.app and auto-save.
  • If no documents are open, and you drag and drop a file into the layers palette, Acorn will now open up that image.
  • Turned off the behavior where the selected tool is saved as part of the image, rather than global for the app. This means switching between open images will always keep the currently selected tool.
  • Additional preset scale levels have been added to the Command+ and Command- shortcuts, which helps out on the lower end.
  • The scale buttons (next to the canvas scale slider) will now stop at a point where the image is zoomed to fit.
  • Acorn will now show a little warning on the canvas when you copy 100% transparent pixels to the clipboard.
  • Canvas notifications are now shown at the top of the canvas instead of smack dab in the middle.
  • Web Export uses fancier scaling, so the edges of circles that butt up against the last column of the image don't get blown out when the image is scaled down.
  • When auto-save is turned on, non-native images (JPEG, PNG, TIFF, basically everything other than .acorn files) will open up as unsaved new images. This is to keep from re-encoding lossy image formats, and automatically losing data in general. If you enjoyed the previous option, you can turn off auto-save in the General tab of Acorn's preferences window.
  • The subpixel anti-aliasing option for text boxes has been removed when Acorn is running on MacOS Mojave 10.14 (Apple has removed subpixel anti-aliasing from the system and made it impossible for Acorn to support).
  • When using Smart Export on single layer via the Export… button, the option to always smart export when saving is now available via the export sheet.
  • Super minor: The web export window will now default to save your image in the same folder the original image was opened from.
    Fixes
  • Various MacOS Mojave 10.14 fixes.
  • Fixed a relatively small drawing problem with ovals.
  • Fixed a problem where you could make an empty selection on layer masks.
  • Fixed a problem where the color loupe would sometimes show up when you press the option key over a palette.
  • Now supporting the new drag and drop stuff from Photos on MacOS 10.14, so we can all enjoy full res images.
  • Fixed a problem where the Close All menu item was unlocalized.
  • Zoom to fit refinements for folks who have their scrollbars set to always show.
  • Fixed a problem where web export wouldn't remember the 'Remove metadata' settings between uses.
  • Fixed a problem when opening certain PDFs and creating an image out of the first page.
  • Fixed some rounding errors when drawing selections.
  • Fixed flickering when selecting text.
  • Fixed a problem where View ▸ Draw Shape Vectors wasn't working correctly with Metal.
  • Fixed a bug where clicking the mouse with the control key down wouldn't bring up the contextual menu on the canvas.
  • Fixed a problem where the pencil cursor would go away when drawing.
  • Fixed a scaling issue with text boxes.
June 21st, 2018 (happy summer solstice!).
    New
  • Added the placeholder '$layername$' to the smart layer export settings field (which works just like '$filename$' does). Read up on Smart Layer Export for more info.
    Fixes
  • Fixed a problem when making a very slow crop, and then you hit the shift key to constrain it to a square, and then out of the blue the crop decides to flip itself. You did nothing wrong, it just happened. And you knew not why. But no longer, for it works as you'd like now.
  • Fixed a problem when using a crop preset with keeping the aspect ratio would break when you got to the edge of the canvas.
  • Fixed a problem when copying a selection from images where certain image properties were present.
  • Fixed a problem where flattening layer filters wouldn't sometimes work when had a selection that was previously moved.
  • Fixed a problem where there would be some visual tearing when using the crop tool.
  • Fixed a problem where using the named color 'windowBackgroundColor' for brushing would fail.
  • Fixed a problem where Copy Merged would sometimes fail.
  • Fixed an issue where using the gradient tool on a layer mask wouldn't show up right away.
  • Fixed an issue where the Metadata window could show the wrong image capture date.
  • Fixed an issue where Acorn's QuickLook plugin could crash with files from Acorn 1.0.
    Changes
  • New hidden pref to coalesce brushing with tablets; copy and paste the following command into Terminal:
March 13, 2018.
    Fixes
  • Fixed blurry icons on 1x displays.
  • Fixed some drawing issues when moving selections at ~87% zoom.
  • Fixed cases where Acorn could crash on 10.11.
  • Fixed a bug where editing text with the Typography palette out could cause a crash.
  • Fixed a problem with the Scale and Rotate command which could clip selections on the right edge by a couple of pixels under certain circumstances.
  • Reduced the amount of canvas flickering when using the Crop tool.
    Changes
  • Defaulting to OpenGL for Macs who have various NVIDIA GeForce GT* GPUs (Metal proved to be a little to crashy on 10.13 for those Macs).
  • New hidden pref to keep Acorn from including the Touch Bar when taking screenshots; copy and paste the following command into Terminal:
Editor
February 14, 2018.
    Fixes
  • Fixed a crasher which could occur on macOS 10.12 when using undo after drawing with the paint brush.
  • Fixed a problem where bringing up the feedback window on 10.13 didn't always allow you to start typing right away.
February 8th, 2018.
    Metal 2 support on macOS High Sierra 10.13 and later
  • So what does this get you? Faster panning, brushing, fills, and just a general speed improvement overall. Acorn should feel more fluid, and we've even seen frame rates over 160 FPS when brushing on a 2015 iMac 5k.
    We've also added some new preferences to choose where the rendering happens, located under the Fussy Stuff tab. You can choose Metal, OpenGL, or Software. You can also choose if the data for your image is stored on the GPU or on the CPU (we realize this is a little ridiculous, and we'll remove these options in a future release, but they are great for playing around with right now).
    If you find that things aren't faster for you- let us know (by emailing support@flyingmeat.com). We're super responsive and would love to hear about any problems, or even if things are awesome++ for you.
