The Pixelmator Team released version 1.2.3 of its next-generation Pixelmator Pro image editing app in late November. Pixelmator Pro 1.2.3 added support for importing ABR Photoshop brushes, improved painting performance of all the brush-based tools (including Paint, retouching, and reshaping tools), increased maximum brush size from 1000 to 2500 pixels, enabled you to invert the brush Shape and Grain textures, and improved the preset importing experience.
Coinciding with Pixelmator Pro being named Apple’s Mac App of the Year for 2018, Pixelmator Pro 1.2.4 was issued with redesigned color balance adjustment tools that use color wheels inspired by those used in the cinema industry to color-grade films. The new tools enable you to adjust color tints of the shadows, midtones, and highlights, and include sliders for adjusting brightness and saturation as well. Additionally, a Master wheel lets you adjust the color balance of an entire image at once.
The update also lets you choose from three image resizing algorithms (Bilinear, Lanczos, and Nearest Neighbor) when using the Image Size command, adds Scale Images and Trim Images actions for the Automator app, displays the last used document size as an option in the template chooser, improves the look of the Curves adjustment in macOS 10.14 Mojave, improves how the Trim Canvas command works with thin images, and prevents a couple of crashes.
