Converting Greyscale Image to Colorscale image Printing Labels / Tickets

[risenrg]

Hi,

Was running low on black ink and found the following command worked great allowing me to print out a shipping label.

magick convert Input.bmp +level-colors red,white output.bmp

I made a quick video of the process below. I did find that i had to convert my PDF label to a BMP before i could get the command to function correctly.

Hope this helps some one.

You should just use magick and not magick convert

Thanks FMW42

Any thoughts as to why when i run the conversion on a PDF the output looks like.




Once i convert the source to a BMP it has no trouble at all.

I'm using
Version: ImageMagick 7.0.5-6 Q16 x64 2017-05-13 http://www.imagemagick.org

And

Ghost Script version 9.21
