trying to convert bmp to png, but getting this error:

here is the bmp file:

http://www.mediafire.com/?ge75ov21jskpzm5

I downloaded your file and IM says it is malformed and will not process it. Also please in the future identify your IM version and platform.


identify -verbose 1ScreenShot00021.bmp
identify: length and filesize do not match `1ScreenShot00021.bmp' @ error/bmp.c/ReadBMPImage/799.
identify: insufficient image data in file `1ScreenShot00021.bmp' @ error/bmp.c/ReadBMPImage/930.

can't I convert by ignoring errors?

ImageMagick's policy is to reject malformed image files to prevent possible security attacks such as denial-of-service or memory buffer overflows, etc.

I found a way to do it with GIMP batch
