G’MIC Montage node

This documentation is for version 0.3 of G’MIC Montage.



  • Don’t forget to set the Input layers… option on the left if you have multiple input layers for your montage.
  • The Custom layout parameter is only active when Montage type is set to Custom layout.

This is basically a string containing expressions such as:

\. H\(a,b\) or V\(a,b\) stand respectively for an horizontal and vertical merge of two blocks a and b\.

\. R\(a\), stands for a 90\-deg\. rotated version of a block a\. Use RR\(a\) and RRR\(a\) for resp\. 180\-deg and 270\-deg\. rotations\.

\. M\(a\), stands for a X\-mirrored version of a block a\. Use MRR\(a\) for a Y\-mirrored version of a\.
  • A block a can be a layer indice or a nested montage expression itself.
  • Layer indices start from 0 (top layer) and are treated periodically.
