Like any image editor of respect, Pixly do support selection too. Apart from doing stuff that you're used to do on the keyboard on the touch screen, most stuff is just as you might have learned from other editors like photoshop and gimp. You can try using the marquee tools, to select and deselect stuff.
The key differences here are:
- Since we may be talking about 4.7"+ devices, and not 17" monitors, you'll notice that the "marching ants" in pixly are actually quite bold and have a greenish tone instead of being thin and black and white. This is to help you notice better what's going on in this tiny screen. This is prone to changes, and I even think I'll allow customization of it in the near future
- Having a finger on the way may be cumbersome to some tools like the magic wand, but fear not, my friend! The marquee tools have a nice preview state shown before you lift your finger.
- If you want to deselect everything, try hitting the "unselect" button that automagically appears in the screen as soon as you get something selected. Check more in the section Deselecting.
- The same as above, not having a keyboard means no shortcut for inverting the selection. Check out Invert to know how to.
Here's what is similar and you probably wanted to know to be sure:
- When stuff is selected, most of the tools will consider that as a boundary. For example, if you have something selected and you decide to use the brush tool, only the selected area will be painted.
- Effects also consider the selection as boundaries. E.g.: When using the hue shift effect, only the selected area get shifted.
- All edit operations, such Free transform, basic transforms, copy & paste and clear will be applied on the selection as well.
