Image Tools

Tools are added to the toolchain when selected from the Add... menu. The tool is added after the selected tool in the chain.

At any point in the toolchain, the image is one of two states: 1) mosaic, or 2) RGB. Some tools can work both states, other tools will only work one or the other. The following list enumerates the valid states for each tool:

Raw images start as mosaic, and are converted to RGB with the demosaic tool. JPEG, TIFF, and PNG images start as RGB.

At the top of each tool pane, at the left is a checkbox that enables/disables the tool; use this to toggle on/off the tool's effect without having to delete and re-insert it. Also in this area, selected tools have copy and paste buttons, so a tool's command and parameters can be copied and pasted into other instances of the same tool. And also in this area, tools that allow application to specific RGB channels have a channel selector.

Most tools have a reset button, that restores the default value to each associated parameter.

Most of the tools are based on a curve-generated lookup table; if applicable, the curve used to make the tool is illustrated in the descriptions below.

A note about the rawproc curve: In both the curve tool display and the lookup table generation, the curve control points are specified as values between 0.0 and 255.0. However, the curve control points and lookup values are floating point numbers, and are converted to the image tone range of 0.0 - 1.0 for application.
