OK, don't want to write very much now. From the readme.txt:
What is APlanner ?
APlanner is a small paint program which can be useful to sketch very large
maps, based on a bmp x/y file array. It could be useful, if you want to sketch
your open world game ideas quickly. Aplanner creates its BMPs in the folder
in which it is started with filenames representing the position in the bmp array.
Because today every PC has lots of HD space, I let Aplanner create plain bmps.
Also jpgs could be problematic, because they tend to loose quality when reloaded
again and again.
From the info box of Aplanner:
APlanner is a small programm that let you sketch your game map or
other large maps in a tiled X/Y bmp-file array.
Press right mousebutton for mini control panel.
Press N,S,W,E Buttons to move through bmp-array.
If a bmp exists it will be loaded. If not, a new one will be created. Actual screen
will be saved to its position when moving to neighbour screens.
For color choice press button
B=Black, R=Red, G=Green, B=Blue T=Text.
Keys: U = UNDO. C = Clear Screen. 1,2,3 = Pencil Size.
Press V for an overview of actual screen + surrounding ones.
While Sketching press arrow keys to flip through the bmp array.
Clipboard is always used for UNDO-Screen.
APlanner should work with any screen resolution
