i am trying to change the splash screen image while booting toradex colibri t20- from default toradex image to my custom image.

thing is that, only specific type of image format, called as .BMZ can only be used for customizing splash screen.

BMZ- it is a bitmap image in compressed format.

i tried too many image creation tools like format factory, etc. i created a bitmap image and compressed into various formats(gz,tar, 7-zip, zip ,etc) and tried directly and also by renaming the extension to \*.BMZ. nothing sort of worked.....

updation can be easily done with the tool provided with colibri t20, the tool detects the bmz image and load directly......

any help is most welcome.........

is there anyway or code to convert the a image of a type to the BMZ format using opencv or matlab...... or is there any software for that......
