Description

This uses an existing miniwindow's offscreen bitmap, to make an image that can be loaded into another miniwindow. This lets you set up offscreen windows (that you may never plan to actually show with WindowShow) as "work areas" for creating text or images, that can be loaded or blended into other windows.

WindowName - the name of an existing miniwindow.

ImageId - the image id to store its image under.

SourceWindow - the miniwindow name that is the source of the image.

Available in MUSHclient version 4.35 onwards.



Lua example

-- create another window
WindowCreate ("map2window", 0, 0, 150, 150, 4, 0, 0x000000) ) -- top left corner

-- pull in map window as "map" from mapping plugin 
WindowImageFromWindow("map2window", "map", "86810b755a33169f0f1d9585")

-- draw our small map into "map2" window
WindowDrawImage ("map2window", "map", 0, 0, 0, 0, 2);

-- show smaller map
WindowShow ("map2window", true)
