Problem with converting images from png to bmp

[wojciech.debowski]

Hi,

I have a problem with converting images from png to bmp. I must convert them to bmp and next create a symbian mbm file from these bmp files. I am thinking I am loosing information from alpha channel during conversion. My piece of code responsible for conversion is as follows:
for($i=0; $i<@source_files; $i++)
{
$image = new Image::Magick;
$image->Read( $source_path.$source_files[$i] );
$image->Set(depth=>24, type=> 'TrueColor',
alpha=>'set',
compression=>'None' );
$image->Write(filename=>$dst_path.$source_files[$i].".bmp");
undef $image;
}
My examle input image is: http://img209.imageshack.us/my.php?imag ... oneta8.png
output bmp image: http://img209.imageshack.us/my.php?imag ... bmpes5.png
and mbm file with some more bmps: http://img211.imageshack.us/my.php?image=mbmfileio9.png

My images in mbm file looks strange. Have You got any ideas how to solve this problem?

With best regards,
Wojciech
