I'm trying to create a bmp image of bitdepth = 1, but unable to do so. The image has always a bitdepth of 32.
How can i do this ?

I am not sure IM can do that. See BMP formats supported by IM at

I've done it using -monochrome and IM version 6.5, previously with IM version 6.2.8 i was unable to achieve the same.

No, -depth 1 didn't seem to work,
I'm writing text in image.
But the image is distorted too much when i used -monochrome.
Is there any thing to avoid this ?
