Because creating maps is quite difficult and cutting in GIMP is very slow, I've written a small application for preparing maps to TB. Enjoy.

I tried it, but i've got an error, and parts like this. (from 8bit tiff 7751x7011, 55mb)
I prefer using modified gimp script.

Good job!

Just a note: I think that having 24/32 bpp maps is wasting memory (card or internal), the device will likely resample it anyway. I find 8bpp enough for any map, but, it is your choice Cool

Here is new version with various bit depth support:

TB Cutter.zip

I only increase bpp after loading bitmap, I plan to cut bitmaps directly in input bit depth to save memory.

Hi,

Thanks for the tool, it works fine! Except I have quite a big map (12000x14000 pixels), and TB Cutter crash when I try to cut it in 600x300 tiles, it creates the first tiles ok (0 to 3000 pixels for the first line of tiles), and then crashes. Do you have any idea to go throught?

Thx

It really seems to crash with big maps, I've just tried 30400x17200 PNG8 map Cool

I see. It will be great once your application will handle 8bpp maps directly, I'm really looking forward to it! GIMP is a pain for large maps.

Ta mapa je moc hezka, mam ji od jednoho sikovnyho uzivatele , cela CR (meritko neumim odhadnout) Wink

. GIMP to neda, mam 1.5 GB RAM + 1.5 GB swap Sad

Guys, why you would to have so large bitmaps difficult to handle ?

BTW, few words about subject Smile

Automation of map preparation process for TB

Input: map(s) picture(s), coordinates info
Output: tiled map(s), tiles index(es), coordinates file(s), tree structure

Process steps for maps/atlases:
- map(s) calibration
- cutting map(s) and indexing (via file names)
- tiles colour reduction (more effective than overall map colour reduction)
- producing folder structures for final map/atlas and files moving
- optionally tared

So tools are - calibrator, cutter, colour reduction filter, tree generator and file mover, tar converter. Something loosed ?

Duffa, would you build such complete tool ?

I've created a dedicated forum for tools, and tb cutter topic Wink
