LazPaint was started to demonstrate the capabilities of the graphic library BGRABitmap. It provides advanced drawing functions in Lazarus development environment. Both provided a source of inspiration for the other and finally LazPaint became real image editor.

Useful keys


Many common actions can be done with the toolbar. Zoom can be changed with the magnifying glass (+ or -), or by clicking on the 1:1 button to show the image at its original size in pixels, or with the zoom fit button to set the zoom so that the whole image be within the window. It is possible to undo/redo the 200 last operations. If you have a doubt on what you are drawing, undo back to the beginning, save a copy, and redo the modifications before going further.

Image manipulation

An image can be resampled, flipped horizontally and vertically. Smart zoom x3 : resize the image x3 and detects borders; this provides a useful zoom with ancient games sprites.

Color manipulation


Filters can be applied to the whole image or to the active selection.
