There are some nice new features in the latest version for iOS including:
What's New in Version 2.3
Pixelmator 2.3 for iOS brings an incredible Quick Selection Tool, a powerful and precise Magnetic Selection Tool, features many small, but awesome improvements to the selection experience on iOS, and more.
- The advanced Quick Selection Tool lets you make incredibly accurate selections.
- The smart Magnetic Selection Tool snaps precisely to the objects you trace.
- Many small, but awesome changes improve the selection experience on iOS.
- When making selections, you can now tap Invert to invert your selection.
- The outline of selections made with the Color Selection Tool is more precise thanks to a content-aware smoothing algorithm.
- The all-new marching ants design improves performance and has ants that actually march around your selections.
- The Color Selection Tool is now faster (especially on older devices).
- Added a Create New selection mode, which is now the default.
- A live preview of your final selection is now shown when using the Add or Subtract selection modes.
- You can now transform selections in the Arrange pane.
- Selections now snap to layers and the canvas, just like layers do (but you can turn this off by turning off Guides).
- Selections made with the Free Selection, Rectangle Selection, and Ellipse Selection tools now always snap to pixels, meaning there won’t be any unwanted, half-transparent pixels at the edges of a selection when you copy, delete, or transform it.
- The selection paths of the Free Selection Tool are now made up of twice as many points, which makes them smoother.
- When you open up Select with an already selected area, the selection tool that you were using previously will automatically become active.
- When moving a selected area, dragging inside the selection will move it, and dragging outside the selection will now pan the image.
- The selection outline that is added as you select with the Free Selection Tool now has a subtle animation.
- When making selections with the Quick Selection or Color Selection tools, the selection preview now fades into the marching ants.
- Tapping Undo after transforming a selected area sometimes used to make that area flicker. Fixed.
- When using the Free Selection Tool, quickly tapping could sometimes make really small selections instead of adding points. Fixed.
Improvements and bug fixes:
- Use a two finger double tap to zoom in or zoom to fit.
- The 9:16 aspect ratio is now in the list of ratios in Crop.
- The request to let Pixelmator access your Photos library wouldn’t appear if you tried to save to Photos before having opened an image from Photos – it does now.
- If you use Copy to Photos to save a new image to your Photos library, you’ll now be able to use Save to Photos to save over that new image.
- If you drag a layer that is not selected (the transform handles aren't visible) and it does not fit in the screen, the layer will not be moved. To move it – first, tap to select it.
- When you hold two fingers to rotate a layer but one or both fingers are outside the currently selected layer, other layers in your image will not be selected – first tap to select the layer you want to rotate, then hold two fingers inside it to start rotating.
- Zoom animations are a little more smooth as they now have subtle ease-out transitions.
Apple Pencil improvements and bug fixes:
- When using Apple Pencil, the brush size of the Quick Selection Tool is pressure-sensitive.
- Selections made using Apple Pencil and the Free Selection Tool are now more accurate.
- The transform handle area is now smaller, giving you more precision.
Pixelmator for iPhone improvements:
- The Select and Distort tool choosers are now laid out more symmetrically.
- The selection mode in the Select tool chooser is highlighted more clearly.
- Tapping to choose a selection mode will now close the Select tool chooser.
Pixelmator 2.3 for iOS has a bunch of other great improvements and fixes.
I've been using Pixelmator as my only image editor on both Mac and iOS for years now and highly recommend it.
