+ | ====== colorpicker ====== | ||
+ | ===== Motivation ===== | ||
+ | As part of a toolbox with a GUI that supports statistical map overlay, I wanted to have a nice interface to select (pick) colors. Most programs (e.g. Photoshop) have a comparable option. | ||
+ | |||
+ | ===== Function reference ('help colorpicker' | ||
+ | < | ||
+ | |||
+ | FORMAT: | ||
+ | |||
+ | Input fields: | ||
+ | |||
+ | icolor | ||
+ | icnames | ||
+ | |||
+ | Output fields: | ||
+ | |||
+ | color Cx3 RGB color (values in the [0...255] range)</ | ||
+ | |||
+ | ===== GUI layout and functionality ===== | ||
+ | The general layout is always the same and looks like this: | ||
+ | |||
+ | {{: | ||
+ | |||
+ | Each of the five areas showing a color-gradient is click-sensitive, | ||
+ | |||
+ | Additionally, | ||
+ | |||
+ | The buttons on the lower right side will | ||
+ | * reset the color to the values given at call time (Reset) | ||
+ | * close the dialog without altering the values given at call time (Cancel) | ||
+ | * close the dialog and return the colors as they were displayed at the time (Accept) | ||
+ | |||
+ | If multiple colors are to be shown (e.g. a palette), names can be given and instead of one uni-colored patch in the top right corner, a grid of colors is presented, which itself is click-sensitive to switch between colors: | ||

+ | |||
+ | ===== Notes ===== | ||
+ | This function requires the [[xfigure]] class to be working properly! |
