Groups can be defined in text files just like tool lists, each tool on a separate line; in fact, the syntax is identical. A group can also be defined as follows:
group:resize:800;sharpen:1with the tools separated by semicolons, either in the input.raw.libraw.default property or in an img command line parameter. Indeed, a rather useful group for input.raw.libraw.default would be:
group:colorspace:camera,assign;subtract:camera;whitebalance:camera;demosaic:ahd;blackwhitepoint:rgbor in a text file:
colorspace:camera,assign subtract:camera whitebalance:camera demosaic:ahd blackwhitepoint:rgbeither which for a raw file would provide a scaled RGB image for further editing. When a group is added to the toolchain, it looks like this in the commands pane:
resize:800 sharpen:1The insertion of the tools cannot be undone. Make sure you have the right tool selected before inserting the tool list. Tool list files can be created with any text editor. If a property needs to be set to a certain value, specify it with a set: command, which will only apply for the toollist. Here's a complete example, turns a color negative image into a normal positive:
set:tool.blackwhitepoint.auto=1 blackwhitepoint:red blackwhitepoint:green blackwhitepoint:blue curve:rgb,0,255,255,0 whitebalance:auto
