KaleidoPaint

October 26, 2023

Removes temporary code needed to work around a bug in iOS 17.0.x. This new version runs correctly on iOS 15, 16 and 17.1 or later.

October 2, 2023

– Adjusted navigation bar for iOS 17 compatibility. – When running on iOS 17, the navigation bar includes a drop-down menu that lets you · export your drawing's source code · rename your drawing (However, iOS 17.0.2 is a bit quirky about how it updates the navigation bar: you'll see the new name, then the old name, and then — after a few seconds wait — the new name again.)

- Aspect ratio snaps more easily to 1:1 ratio for perfectly square patterns. - Shear snaps to half-integers for precise "half drop" patterns. Thanks to Rebecca Elfast for this suggestion. - Drawing snaps to 90° alignments.

Version 3.0.2: Removes a no-longer-valid constraint from KaleidoPaint 2 that was preventing the pen from resizing correctly when the aspect ratio was set to an extreme value. Thanks to Francine Champagne for reporting this bug. Version 3.0.1: On iOS 16, moves the drawing title up to the navigation bar, to allow more space for the drawing itself. Version 3.0.0: - Entire app re-written in Swift and SwiftUI. - File browser lets you organize your drawings into folders. - File browser supports iCloud Drive as well as local storage on device. - Color picker offers a choice of five color selection methods (grid, spectrum, sliders, eyedropper or hex code) and a user-customizable saved-color palette. - Separate line color ("paintbrush") and fill color ("paint bucket"). - You can copy the color of any dot, line or filled region directly to the paintbrush, the paint bucket or any other dot, line or filled region. - You can copy the thickness of any dot or line directly to the paintbrush or any other dot or line. - Options to "change all of same color", "change all of same thickness" or "delete all of same color". - Exports images to any folder. - Option to export images with transparent background. - Adjustable parameter for less vigorous or more vigorous line smoothing. - Simple slider-based interface to adjust drawing's aspect ratio and shear. - Default grid alignment is now consistent among the symmetry patterns *2222, 2222, 2*22, 22*, 22×, **, *× and ××, in the sense that mirror lines and rotation points agree, to make it easier to see the relationships among those symmetry patterns. - Symmetry panel now positions the buttons for the families (**, *× and ××), (22*, 22×) and (*2222, 2222, 2*22) consistently, so you can easily see what symmetries change and what symmetries stay the same as you switch from one pattern to a different pattern in the same family. This also lets you see how the drawing's symmetries relate to the pattern's name in orbifold notation. - Many thanks to Francine Champagne, Amber van Hoek and Geneviève Crabe for their extensive help improving KaleidoPaint. KaleidoPaint is far better thanks to their ideas. - Special thanks to Francine for creating the icons for the symmetry pattern buttons as well as for her instructional videos and web pages. - Special thanks to Amber for creating KaleidoPaint's elegant icon and for providing spectacularly good drawings for KaleidoPaint's App Store screenshots.

- Color Picker now offers a “wide color gamut” (Display P3) on devices with wide-color displays. Note: When you open one of your older drawings, KaleidoPaint maps the drawing’s “traditional color gamut” (sRGB) to an appropriate subset of the Display P3 gamut, so your older drawings will still look exactly the same, even when stored in the new wide-color format. - Fixed a bug that had allowed a drag in the Color Picker to get “stolen” and re-interpreted as a scroll of the enclosing window. - More efficient GPU usage on iPhone 8 and later (thanks to “non-uniform threadgroup sizes”), for faster rendering. - Added Portuguese translation, thanks to Nuno Fernandes.
