LazPaint is a free and open-source cross-platformnb 1 lightweight image editor with raster and vectorial layers created with Lazarus. The software aims at being simpler than GIMP,5 is an alternative to Paint.NET and is also similar to Paintbrush.67

Rendering is done with antialiasing and gamma correction.8 It can read/write usual image formats9 and interoperate with other layered editors via OpenRaster format.1011 It also imports Paint.NET files (with their layer structure) and Photoshop files (as flattened images).912 Also, it can import 3D objects in Wavefront (.obj) format. There are complex selection functions, various filters13 and rendering of textures.

Colorspace

Colors are stored in sRGB colorspace but drawing functions take into account gamma correction. There are many color manipulation functions such as shifting colors and colorizing.1413 Since version 6, there is a curve adjustments function on RGBA channels and according to a corrected HSL colorspace.15 This correction takes into account the gamma factor and also perceived lightness according to the hue.

Vector shapes

Since version 7, shapes are stored with vectorial information. Thus they are editable after they have been drawn and are rendered again in case of layer transform. Layers are converted when needed to raster or vector. If a tool like the pen is applied, the layer is rasterized and vectorial information becomes unavailable.

Filling can be a solid color, a gradient or a texture. It can apply to simple shapes, complex curves, text and shaded shapes.
