Has drawing tools, vector shapes, phong shading, curve adjustments, filters, render some textures, Python scripting. Uses Qt5 widgetset. Features: 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.

Radial blur : non directional blur Motion blur : directional blur Custom blur : blur according to a mask Sharpen : makes contours more accurate, 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 Scripts: scripts are provided to do layer effects. You can as well write your own Python scripts.
