Updated Transform so it accepts a greyscale input per parameter. For each pixel, the parameter is multiplied by 2*v-1 (v being the value of the input's pixel) which makes it possible to affect the strength of each transform using an input image. New effects such as whirl and color guided offsets are now possible.
Added Decompose node (does the opposite of combine).
Used another color for inputs/outputs that expect/generate a greyscale image.
Added a noise node (paints randomly pixels in black or white).
Modified blur so direction can be selected (horizontal, verticla, or both).
Updated code to use string formats instead of conversion + concatenation.
- shader updates are delayed by .25 seconds to avouid UI freeze
- fixed GraphNode initialization upon loading
- started obsoleting get_source_rgb and get_source_f functions
- updated colorize node to use gradient
- image node can now be loaded/saved
- removed iqnoise node
- rewrote perlin shader to support a seed parameter (seed is calculated from the node's position, so just move it to reseed)
- Added voronoi noise node
- updated code to use % formats instead of concatenating strings (should solve type problems in shaders)
- reworked the context menu (now has submenus)
- fixes in the gradient editor
Added Image node that can be used to import textures
Renamed all get_shader_code methods to _get_shader code so a caching system can be integrated in node_base (and we can get rid of get_source_rgb and get_source_f functions)
