identify with multiple images

[snibgo]

This follows a thread in Users: viewtopic.php?f=1&t=26809

The behaviour for "identify" changed between 6.8.0-0 and 6.8.9-0. The effect of the change is such that if the format string contains %n (the number of images), the rest of the format string is no longer repeated, once per image. I think this new behaviour is a bug.

This new behaviour applies to "identify" but not "convert -ping" (in 6.8.9-0 and 6.9.0-0). This still gives the old behaviour, issuing a format for each image, even when the format string contains "%n".

Bad behaviour of current "identify":

Code: Select all

f:\web\im>c:\im\ImageMagick-6.9.0\identify   -ping   -format Depth-%p:%[depth]\nColors-%p:%k\nPageGeometry-%p:%g\nResolution-%p:%[xresolution]x%[yresolution]\nType-%p:%r\nCurrentPage-%p:%p\nTotalPages-%p:%n\n   x.tiff

Depth-0:8
Colors-0:256
PageGeometry-0:640x480+0+0
Resolution-0:0x0
Type-0:PseudoClass sRGB
CurrentPage-0:0
TotalPages-0:2

Good behaviour of current "convert -ping":

Code: Select all

f:\web\im>c:\im\ImageMagick-6.9.0\convert   -ping   x.tiff   -format Depth-%p:%[depth]\nColors-%p:%k\nPageGeometry-%p:%g\nResolution-%p:%[xresolution]x%[yresolution]\nType-%p:%r\nCurrentPage-%p:%p\nTotalPages-%p:%n\n   info:
