There are two colour pickers in the toolbar: the one on the left is for selecting the target colour, and the one on the right is for selecting the destination colour. Tap on the colour well to bring up the colour panel, or select the button to sample a colour from the canvas.

The scope picker lets you choose between affecting the current cel, all cels on the current layer, or all cels i.e. the whole project.

You can also choose to change the target colour to the destination colour in the palette if it is present by selecting the ‘Update Palette’ button.

You’ll see a live preview of the colour replacement when any of these options are changed.

Use the ‘Cancel’ button to cancel changes and use the ‘Done’ button to apply them.

Resize the canvas

You can adjust the size of the canvas by selecting the ‘Canvas size’ option, which will take you to the canvas resize screen. Touch and drag on the resize handles to adjust the size, which can be made smaller or larger than the current canvas. Touch and drag on the image to reposition it within the frame.

The location and size of the current selection are shown in the bar at the top; tapping on these will open a number pad where you can input an exact value.

Use the ‘Cancel’ button to revert all changes and return to the canvas. Use the ‘Reset’ button to reset the changes but stay on the canvas resize screen.

When you are happy with the new size, press the ‘Done’ button to resize. Resizing the canvas is undoable, so you don’t need to worry about losing work if you make a mistake.

Grid

Pixaki has a fully customisable grid that can be overlaid on the artboard to help with aligning elements or creating tilesets. Toggle the grid on or off using the switch in the adjustments menu.

Tint will recolour the images whilst maintaining some of the shadows and highlights so that you can see the details in the image.

Silhouette will show the shape of the images on the previous and next cels, ignoring the original colour but maintaining the alpha values.

The previous frame’s image will be coloured red, and the next frame’s image will be coloured green.

Loop

With the the loop option turned on, the frames from the start of the animation will be shown when the end frames are selected, and the frames from the end of the animation will be shown when the start frames are selected. This is useful when creating looping animations.

Keyframes before / after

These options control how many of the keyframes before and after the current keyframe are shown. Up to five keyframes can be shown in both directions. The onion skin images will decrease in opacity depending on how far away from the current frame they are.

Save as Defaults
