Here a little script to load a TGA image file and create a GDI+ bitmap. Currently supported TGA formats are  1/8/15/16/24 and 32-bit.
As v0.85 is written completely in AutoIt, it might take some time to convert larger 8/15/16/24/32-bit images. ☕

Thanks.

Since monoceres has released 
I searched for a way to map the 2D image of the earth to a 3D sphere with rotation.
 
Here the result (after 9 years of research ^^) as a non realistic physical animation:
 ==> 
 
Due to the fact that AutoIt / GDI+ are not that fast I couldn't add a moon animation additionally.
 
Thanks to one of Eukalyptus' code to pointing me to the right direction. U rock man.

Change log:
 

Heres a function for searching for a bitmap within another bitmap. The heart of it is written assembly (source included) and working pretty quick I feel. I have included an example which is pretty basic and should be easily enough for anyone to get the concept. 
You will be given a small blue window that will take a screencapture of that size:

 
It will then take a full screenshot and highlight all locations that it found

Please let me know if you have any issues or questions. Thanks!
