LazPaint is an image editor with layers and transparency. It supports the OpenRaster format so it can interoperate with MyPaint, Gimp and Krita.


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. Thanks to the help of Lazarus community, the program has been compiled on Windows, Linux and macOS.


Files: read and write a variety of file formats, including layered bitmaps and 3D files.

Tools: many tools are available to draw on the layers.

Edit/Select: select parts of an image with antialiasing and modify the selection as a mask.

View: color window, layer stack window and toolbox window.

Command line: call LazPaint from a console.

Scripts: scripts are provided to do layer effects. You can as well write your own Python scripts.


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

    Colorize : set the color of an image while preserving intensities
    Shift colors : cycle colors and change colorness (saturation)
    Intensity : make colors lighter or darker without making them white
    Lightness : make colors lighter or darker by making them whiter
    Normalize : use the whole range of each color channel and alpha channel
    Negative : invert colors (with gamma correction)
    Linear negative : invert colors (without gamma correction)
    Grayscale : converts colors to grayscale with gamma correction


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

    Radial blur : non directional blur
    Motion blur : directional blur
    Custom blur : blur according to a mask
    Sharpen : makes contours more accute, complementary to Smooth
    Smooth : softens whole image, complementary to Sharpen
    Median : computes the median of colors around each pixel, which softens corners
    Contour : draws contours on a white background (like a pencil drawing)
    Emboss : draws contours with shadow
    Sphere : spherical projection
    Cylinder : cylinder projection
    Clouds : add clouds of the current pen color
