Pixel Studio

A compact sprite editor built around a 16 × 16 canvas, named tools, a palette and a live preview. The editing surface stays central at every zoom level.

Run it

Build the examples with devenv shell -- lcom-ng-build, then run:

lcom-ng run -- build/examples/pixel_studio build/pixel_studio_sprite.h

Try a complete workflow

Draw or fill a region, sample a color, and inspect the preview. Use undo, redo and reversible flips to explore alternatives. Export the sprite as a timestamped C header for another program.

Every pixel countsA 16 by 16 canvas, indexed palette, native-size previews and real history controls.

A complete brush strokeDragging interpolates between cells, so fast strokes stay connected.

Fill a connected regionThe fill tool replaces only the connected region, with one reversible history step.

Pixel-perfect keyboard editingArrow keys move a visible cursor; Enter applies the selected tool and the footer identifies the pixel.

Explore a variationFlip horizontally or vertically with X and V, and reverse the edit through normal Undo.

Ready to use in CExport creates the reusable C array and only reports success after the file is complete.

Mouse and keyboard, togetherTool keys, palette stepping, keyboard drawing, transforms and history are all documented in the app.

What it demonstrates

PS/2 gestures, stroke interpolation, flood fill, bounded undo history, RTC timestamps and C asset generation.

The editable sprite is 16 × 16 pixels. Export produces C data; it does not reopen arbitrary image files.
