LazPaint – cross platform image editor with layers and transparency

LazPaint is an open source image editor written in the Lazarus (Free Pascal) programming language.

The software uses the BGRABitmap library.

LazPaint is released under an open source license.

Features include:

  • 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.
  • Image manipulation.
  • 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:
    • Radial blur : non directional blur.
    • Motion blur : directional blur.
    • Custom blur : blur according to a mask.
    • Sharpen : makes contours more acute, 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.
  • Command line: call LazPaint from a console.
  • Cross-platform support – runs under Linux, Mac OS X, and Windows.
