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......
I would have also suggested to try compressing a normal bitmap with gzip. After doing some research however, I found out, that the guys over at toradex.com seem to sell a tool called
"Splash Screen Customizer tool":
converts an unlimited number of bitmap files to the Bmz format for the cost of 4 Support Hours
(see Toradex Knowledgebase)
They also offer you the possibility to send in your bitmaps and convert them into .BMZ for you:
Toradex converts one bitmap for 1 Support Hours. (Please send us the bitmap in the correct resolution and with 8BPP)
I don't know for sure if their .BMZ format is the same thing as a compressed bitmap image or not, but I would try to give it a shot compressing multiple bitmaps with 8BPP into a single gz Archive (Is there an animation on the splash screen?). If that does not work, I think the only options you have are giving up on the custom splash screen or paying them money to give you the tool/convert the bitmaps for you.
