Panel of Nine

Interactive image editors allow us to tweak a slider to adjust an effect. ImageMagick is non-interactive, but here are simple scripts to quickly see the effect of adjustments without needing complex Javascript or whatever.

Scripts

A sample source image, toes.png.

set SRC=toes.png

blend9.bat

Most of these scripts need one input image. blend9.bat needs two.

call %PICTBAT%sigmoid9 %SRC%

toes_sig9.pngjpg

sigSetSd9.bat

Tries to find the sigmoidal contrasts for nine standard deviations. Each cell shows the goal SD and, if a solution is found, the sigmoidal contrast.

call %PICTBAT%sigSetSd9 %SRC%

Scripts

For convenience, .bat scripts are also available in a single zip file. See Zipped BAT files.

The panel9 scripts are similar to each other. Just one is shown here. They are all available in panel9.zip.

colors9.bat

rem From image %1, makes 9-panel with varying number of colors.
rem %2 is first number. Default 1.
rem %3 is increment. Default 1.
rem %4 is 0 (no dither) or 1 (dither). Default 1.
