Canvas View

The canvas toolbar allows you to change colors, brushes, drawing modes, undo, redo and clear your drawing.

Drawing is easy. Just touch the screen and move your finger. Some of the brushes will be affected by how fast you move your finger. Some brushes will draw larger shapes when you draw faster. Some will draw darker (more dense) when you draw slower. Experiment with drawing speeds for the various brushes.

Save and Go to Gallery

This toolbar icon is what you use to save your picture and go to the Gallery view. Also, if you press the Home button to close the OmniSketch App your picture will be saved.

Drawing Color Palette

This option opens the color palette so you can change the current drawing color.

There are two selectors on the color palette. The two small transparent circles indicate the location of the selectors. The large color circle at the center allows you to select the color hue. The ring around the outside allows you to select the color luminosity. NOTE: The luminosity defaults to the darkest setting which will be black for all hues. In order to get a color you must adjust the luminosity.

Background Color Palette

The color palette used to change the background color of your pictures works exactly the same way as the color palette used for drawing. The background color can be changed at any time without affecting your drawing.

Brush Control

The brush control allows you to adjust the line width, opacity (transparency) and for some brushes the adjustment value of the brush. Adjusting the opacity will allow you to see through what you’re drawing to the background and to what was previously drawn.

Some brushes have an adjustment value that allows you to change how the brush’s drawing algorithm works. Experiment with the various brushes with adjustment available.

Blend Mode

There are many different blend modes available. Blend modes control how the colors you are drawing will blend with the colors that have already been drawn. Normal mode simply places new colors on top of old colors. The Clear mode allows you to use any brush as an Eraser. Experiment with the different Blend Modes. You can create some stunning effects!

Mirror Mode

The mirror modes allow you to draw with symmetry. You can mirror your drawing vertically, horizontally or both vertically or horizontally.

Brush Select

Tapping the Brush Select icon allows you to toggle from erasing to drawing and to select what brush you want to use for drawing. If the eraser is currently selected you will be switched to drawing mode. If you are currently in drawing mode a box will be drawn around the brush icon. If drawing mode is selected and you tap the brush icon you will be able to change the brush.

The App comes with the standard set of brushes. You can switch between brush sets by either swiping left or right or tapping on either side of the row of dots below the brush icons. Additional brush sets can be purchased and more will be added in the future.

Eraser Select

Tapping the Eraser Select icon will cause the Eraser to be selected. Erasing removes drawn colors from the canvas. When the Eraser is selected a box will be drawn around its icon.

Tapping the Undo icon will remove those changes in the reverse order that they were performed. Up to 20 changes can be stored in the undo queue. The Undo icon will be dimmed when there is nothing to undo. NOTE: If you draw for a long time without removing your finger from the screen it can make the Undo and Redo operations slow.


The Redo icon does the opposite of the Undo icon. If you Undo something you’ve draw it will be added to the Redo queue. Redo allows you to Undo an Undo. If you undo a line you’ve draw using Redo will put the line back. The Redo queue can also hold up to 20 changes. If you Undo a change and then draw more the Redo queue will be cleared and you will not be able to Redo what you Undid. The Redo icon will be dimmed when there is nothing to redo. NOTE: If you draw for a long time without removing your finger from the screen it can make the Undo and Redo operations slow.
