Re: -composite with spacekey

If the gallery name is provided by the user in any way, this is a potential security problem. You may have to use escapeshellarg() on all arguments for which you are not absolutely certain that they don't contain characters that may be unsafe in the shell.

Re: Use pngquant (libimagequant) for quantization to palette

I'd think the theory was that the PNG coder would be able to write the filter output pixel values 1:1 to a correct PNG file, including emitting a tRNS chunk if necessary. I haven't tried a filter, but using convert to create a TIFF file from a pngquant-ed PNG and converting that TIFF back to PNG res...

MPEG delegate always detected

The detection code for the MPEG delegate in configure is apparently broken in 6.8.9-6 (and possibly earlier releases), since it always "detects" ffmpeg, apparently due to a confusion between MPEGDecodeDelegateDefault and MPEGDecodeDelegate and how those are assigned.

Re: 4meg image creates multi-gigabyte temp file & crashes

Is there any chance to get the above patch or something equivalent included in ImageMagick?

Re: Links in www/api Documentation bloated with 16384 "../"

I neglected to mention that colorspace.html pixel-view.html had even more "../" and "www" in the links. I thought it was just 16384*3, but right now in 6.8.3-5 there are about 512k unnecessary "../" in every link in colorspace.html. As a result, each of those files is ~ 48MB.

Links in www/api Documentation bloated with 16384 "../"

Somewhere around 6.8.2, the HTML documentation included in the distribution archives in www/api has increased in size by a factor of almost 2 - from 800k per file to 1.6MB per file. The cause is an inflationary growth in '../' in the relative links, from around 8192 to 16384 repetitions of '../'. As...

Re: 4meg image creates multi-gigabyte temp file & crashes

This problem can be mitigated - at least on POSIX systems - by deleting the temporary file as soon as it is created. This will actually free the diskspace occupied by the file as soon as it is closed or the ImageMagick terminates. We're using the patch below for automated/unattended use of ImageMagi...
