Hello folks,

I cannot manage to transform a monochrome tiff loaded from disk in an Image object into a bitmap with 1 bit per pixel.
I'm using Magick++, not the command line tool.
I tried with

Code: Select all

image.depth(1)

also with

Code: Select all

image.type(BilevelType)

when getting the depth it was correct, but after writing the image on disk

Code: Select all

image.write("bla.bmp")

the image had 24 bits per pixel.

Is there any restriction that I'm missing? Because from command line it worked...

Thank you
Daiana

seems that setting the depth does not function at all

I managed to reduce bitdepth using quantize, but as far as I understood this function always optimizes the depth, so if I'm asking for a RGB image but the input content is B/W or grayscale I will not get the resulting bitdepth I need.
