Create MBM file from BMP file.

[BugBuster]

I'm trying to convert a 24bit colour BMP file (131 * 172 pixels) into an MBM file for use in a 3650 as the wallpaper image.

The command I'm using is

bmconv /n backgroundimage.mbm /c24background.bmp

The response I get back is:


BMCONV version 103.
Compiling...
Multiple bitmap store type: File store
Epoc file: backgroundimage.mbm

Bitmap file 1 : background.bmp
Success.

However when I transfer the file into the phone all I get is a blank image (i.e. as if the image has not been read).

What am I doing wrong ?

If I do a BNCONV /u on the MBM file I get back, more or less, to the BMP file I started with so the file is obviously not being corrupted.

I know the file is OK as if I convert it to a JPG file I can load the file into the phone and get it to do the conversion but that's not what I'm after.

Hi

Just couple of comments. Why you use /n there. that disables compression, so you would get alot bigger output mbm file, secondly nokia 7650 & 3650 can only show 12-bit colors, so /c12 would also make nearly half sized output file when compared to /c24.

In case you managed to get the bmp out from the mbm, then I quess your file shoudl be ok. so then it's gotta be something wrong when you set it to be the background.

could you tell what process you use for setting the image, so maybe somebody will find the cause of the error there ?.

Hi yucca

I've tried with and without the /n qualifier.

To get it as the background I used Phoenix to copy it into c:\System\Data (in a 3650) and overwrite the existing background image.

I have to admit that I thought that the C24 was the format of the source file and not the destination file.

Ultimately the image will be set during build time by setting the ini/iby files as required.

Thanks

Hi

In case you are replasing the original mbm, you should then propably include two images in it. I saw in NewLC forum that the picture sizes should be like this:

1, 174x130 (Background image)
2, 143x101 (Dimmed background image)

maybe you want to try it again with two images in it.

Ok. I've tried it with 2 images and it seems to work fine - Thank you very much for your help.

As a matter of interest, when does the 2nd image get used as I notice it is in landscape format and not potrait ?
