I have used a number of different values for rate, including 115 and higher. The option is entirely ignored and a lossless image is always output.

I'm trying to encode images with JPEG 2000. I'm using "-define jp2:rate=x,x,..." to set quality levels. This options seems to be ignored by ImageMagick. I would expect these two commands to produce similar or identical results: $ opj_compress -r 50 -i example.png -o example.opj.jp2 $ convert example ...

Most of the time there aren't any commit messages in the SVN repo.

This sucks a lot. I can't follow what's going on without lots of effort.

It would be awesome if each commit at least had a message. That's not hard to do.

I'll elaborate on this pain. I have a script that automates an install of ImageMagick. This script fetches a particular known version of ImageMagick source, builds the source, installs it on the local machine. It is important that I point to a particular known version of ImageMagick in case I need ...

What seems to be happening is that, when reading directly from a file, we always get a FileStream image blob type. This makes sense. For the case where we don't explicitly specify the input format, the STDIN stream gets written to a temporary file and ends up as a FileStream image blob type by the ...

I'm trying to read a WEBP image from the command line over STDIN. This works in most cases except when I specifically tell convert that the incoming data is WEBP format. $ convert Example.webp info:- Example.webp WEBP 2448x2512 2448x2512+0+0 8-bit sRGB 58KB 0.100u 0:00.099 $ convert WEBP:Example ...

The JPEG XR delegates seem to be misconfigure in a few ways. Firstly, variables in configure and configure.ac seem to have an accidental extra typo 'M'. 'JXRMEncodeDelegateDefault' should be 'JXREncodeDelegateDefault'. This makes it so JPEG XR delegates don't get added when ./configure is run. I've ...

The following command ignores the valid convert option -define png:compression-filter=0 $ convert logo: -define png:compression-filter=0 PNG:- > /dev/null convert: ignoring invalid defined png:compression-filter =0 @ warning/png.c/WritePNGImage/12024. Seems there was a forgotten 'else' in png.c ...
