Channels to Layers

Channels to Layers

A Krita plugin designed to split channels from a layer to sub-layers:

• RGB
• CMY
• CMYK
• RGB as grayscale values
• CMY as grayscale values
• CMYK as grayscale values

color model CMYK from Wikipedia

Usage

1. Select a layer to convert
   Selected layer must be a 8bits RGBA paint layer, other layer type are not (yet?) supported
2. Execute script from Tools > Scripts > Channels to Layers
3. Choose options from user interface
   Layers management

• New layer group name
  New layers will be grouped in a Group layer for which name is defined here.
  Possible keywords can be used to build layer name:
  {mode} : conversion mode (RGB, CMY, CMYK, ...)
  {source:name}: original layer name
• New layers color name
  Define name for each layer created from channel.
  Possible keywords can be used to build layer name:
  {mode}: conversion mode (RGB, CMY, CMYK, ...)
  {color:short}: current channel color, short value (R, G, B, C, M, Y, K)
  {color:long}: current channel color, long value (Red, Green, Blue, Cyan, Magenta, Yellow, Black)
  {source:name}: original layer name
• Original layer
  Define what to do with original layer
  Unchanged let original layer visibility unchanged
  Visible set original layer visibility to 'Visible'
  Hidden set original layer visibility to 'Hidden'
  Remove remove original layer
