Hi,
i have a couple of color TIF images (Green, Pink, and Yellow). i need to convert to black and white through unix command line.
i tried the following:

convert +compress -monochrome ImageName Imageout
convert +compress -type Bilevel ImageName Imageout


commands and they get only converted to grayscale.

My Question is there a command i can run to convert all the images to Black and white without setting a threshold as they differ between images


Thanks

see my replies at viewtopic.php?f=2&t=15301

please provide a link to your image and an explanation of what you would like to see in your result as to which colors get converted to white or black. Then I or others can try to see what we can do for you.
