Hi,
I have not dive into different image formats but base on previous experience, i
believe Stephane was right about this. So far when dealing with different bits
per pixel, tif could be the way to go. The tif created by imwrite would be able
to read by imread without any issue.
ps: In Scilab, binary image should be in %t, %f, however, some functions might
not support binary so you might need to convert to relevant format before
operation.
ps2: If I remember correctly %t %f were detected as int32 in C gateway. so,
there might be something still not fully covered during conversion.
thanks.
rgds,
CL

Hi,
True BW Jpeg is not possible. Use TIFF format instead.

Dear Experts,
I try to save a black/white image as a binary image.
That means: An image with bit depth of 1.
"imwrite" from IPCV however seems to save the image at
least as a 8-bit-image.
The array I want to save as an image consists of "0" and
"1" only.
The output file type must be ".jpg".
Thank you,
Philipp
