Hi,
I've noticed some differences with the way Magick::ping() works between
if you use it via passing a filename directly (using a std::string), or
passing it a Magick::Blob. When I pass the filename directly, I get the
correct columns() and rows() values, but when I pass it a Blob it seems
to give me the size of the EXIF thumbnail instead (for JPEG images -- I
haven't tried it with any other kinds of images). As far as I know I'm
reading the whole image into memory correctly. I'm using
ImageMagick-6.2.5 on Windows XP.
Thanks,
;) james.
