Images

Place an image

File → Import / Place Image… places PNG, JPEG, WebP, GIF, BMP, AVIF or SVG artwork on the active layer. Images are stored inside your .illu file, so the document travels as one file. SVG files can also be opened directly as a new document with File → Open….

Crop

Select an image and choose Vector → Crop Image…, set the crop, then Apply Crop.

Rasterize

Rasterize turns whatever is selected into a single image at a resolution you choose. Use it in two cases:

  • A heavy drawing. A sketch made of hundreds of brush strokes is slow to move and zoom. Rasterized, it is one image and feels light again.
  • An oversized photo. A 6000 px photo shown 600 pt wide carries far more pixels than the page needs. Re-sample it to the size it is actually shown at and the document gets smaller and faster.

Select the objects (or the image), then choose Edit → Rasterize…, or right-click and choose Rasterize…. In Simple Mode it is on the selection bar.

  • Resolution: 72 dpi is small, 150 dpi is sharp on screens and tablets, 300 dpi is for print. You can type any value, or type the width in pixels you want instead.
  • Result shows the image size you will get. For a photo, Now shows what it has today, so you can see the saving.
  • The image takes the place of the objects: same position, same place in the stacking order. A drawing gets a transparent background; a photo keeps its place and size on the page.

Note: Rasterized artwork is pixels: it can no longer be edited as shapes or text. Undo (Ctrl Z) brings the original back, so keep a copy on a hidden layer if you may need the vectors later.

Blend modes such as Multiply are baked into the image and no longer mix with what is underneath. Very large selections are limited to a resolution the device can hold in memory; the dialog tells you when that happens.

Smart Vectorize

Illusion is building Smart Vectorize, an in-editor tool that turns a sketch or PNG into editable, layered vector paths, run locally with no account. It's in testing now.

Picking colors from an image

The Eyedropper can pick a single color out of an image.
