Ruwa Documentation

Create a project

Pick a preset or set up a new Ruwa canvas yourself.

Ruwa New Project screen

Two ways in: grab a preset on the right, or set everything by hand on the left. Presets only fill in the starting values, so you can take one and still change anything before you hit Create.

Project presets

The tabs above the preset list group starting sizes by what they're for:

GroupWhat's in it
BasicsGeneral-purpose square, landscape, and portrait canvases.
ScreenSizes for artwork that lives on a screen.
IllustrationCommon starting points for illustrations.
Comics & MangaPresets for comic and manga pages.
PrintSizes prepared for print work.
Covers & PostersProportions used for covers and posters.
Pixel ArtSmaller canvases for pixel work.

Basics, shown above, contains:

  • Quick Sketch — 2048 × 2048. A solid default if you don't want to think about it.
  • Square Canvas — 3000 × 3000.
  • Landscape Canvas — 4000 × 3000.
  • Portrait Canvas — 3000 × 4000.
  • Large Square — 4096 × 4096.

Presets aren't locks

Pick one and change whatever you want after: name, canvas type, color depth, dimensions, background.

Project preview and name

The preview shows the proportions you're about to get. In the middle it prints the name, the dimensions, and the aspect ratio, which is a decent last chance to catch a wrong number before the project exists.

The Name field sets the name Ruwa shows. New projects are called Untitled Project until you say otherwise.

Canvas type

Classic canvas

Fixed width and height. Use it when you know the dimensions you need.

Infinite canvas

No outer boundaries. The work grows as you draw past the edges.

Color depth

Color depth is how much precision each pixel gets. More depth holds more tonal information and eats more memory.

OptionWhen to use it
8-bitThe practical default for sketches, painting, and most finished work.
16-bitWhen you want smoother gradients and more room for color adjustments.
32-bit floatWhen you need the highest precision and can pay for it in memory.

Not sure? Take 8-bit.

Dimensions

On a Classic canvas, Width and Height are the pixel dimensions. The link control between the fields holds the current proportions while you change a number.

Bigger canvases give you room for detail and cost you memory. Heavy brushes and effects are what slow down first.

Background color

Background Color sets what the canvas starts as. Click the swatch or type a hex value like #FFFFFF.

Create the project

Create Project opens the editor with everything you picked. The number next to the button is a rough memory estimate for the starting canvas, worked out from its dimensions and color depth. It isn't the size your .rwf file will end up being.
