Greentea

Create and edit BMP for Greentea OS

Some BMPs in Greentea are particularly sensitive to changing the color depth (number of bits per pixel) and compression type. Such files, for example, are 6.bmp and 14.bmp from the ntoskrnl/inbv/logo. If the file 14.bmp changes the compression type or the color depth, then the system will not boot in the debug mode at all.

What should I do in such cases?

It will be useful to check information about the picture through specialized software, for example, Full Image Info (Freeware). Particular attention should be paid to the items BitsPerSample and BMP_Compression. After that it will be easier to decide what to do with this picture.

Tested with GIMP 2.8.18.
