possible bug PCD reader or writer (?)

IM 6.9.8-3 Q16 and IM 7.0.5.4 Q16 Mac OSX

When converting logo: to PCD and then PCD to PNG, the color of the result is showing gray where it should be white.

Code: Select all

convert logo: logo.png

Code: Select all

convert logo: logo.pcd

Code: Select all

convert logo.pcd logo_pcd.png

I just noticed that identify -verbose logo.pcd says the colorspace is YCC. However doing

Code: Select all

convert logo.pcd -colorspace sRGB logo_pcd2.png

Still makes no difference.

Using IM 7.0.5-3 HDRI static on Windows 10 64, I ran the commands from the opening post, only instead of "convert" I used "magick" of course. The commands...

Code: Select all

magick logo: logo.pcd

Code: Select all

magick logo.pcd logo_pcd.png

This is the result...

Odd. That is quite different. But I note that when I did the convert/magick, they both looked the same as my example above. But when I did an IM display logo.pcd. It was also pinkish. I assumed that was due to the YCC colorspace issue.

Do you still get this same result from

Code: Select all

magick logo.pcd -colorspace sRGB logo_pcd.png

Thanks for the problem report. We can reproduce it and will have a patch to fix it in GIT master branch @ https://github.com/ImageMagick/ImageMagick later today. The patch will be available in the beta releases of ImageMagick @ http://www.imagemagick.org/download/beta/ by sometime tomorrow.

Do you still get this same result from

Code: Select all

magick logo.pcd -colorspace sRGB logo_pcd.png

That produces a result nearly identical to the one I posted above.

The result is white with IM 7.0.5.5 beta. So it seems to be fixed when doing

Code: Select all

im7beta magick logo: logo.png
im7beta magick logo.png logo.pcd
im7beta magick logo.pcd -colorspace sRGB logo_pcd_new.png

The output is 768 × 512 per PCD format and the input was 640x480, so there is a grayish pad outside the logo region to fill to 768 × 512.

P.S. One can use -bordercolor to adjust the color of the padding.
