Plz add Google's Guetzli encoder in addition to libjpeg

I've become a supporter and user of (esp. pre-processed lossless) webp, but with more computing power there are obviously still improvements even in ancient formats... behold, Google strikes again: https://research.googleblog.com/2017/03/announcing-guetzli-new-open-source-jpeg.html Guetzli is a JPEG...

Re: Request: add portable.7z files to download set

I'm observing that the most downloaded files from SourceForge are the *portable.zip files; I think it would be worthwhile adding *portable.7z to save some wear and tear on the Internet, being less than half the size (31.6MB versus 74.8MB). We're talking about the same Internet here, the one with al...

Re: FLIF lib 0.2 update

What do you mean by complex delegate requirements? My experience with compiling im was that it's not a matter of configure and make, but to get all file formats inside you have to hunt down and install a lot of libs. That's why I'm happy that there are complete and updated binary releases of im all...

Re: FLIF lib 0.2 update

We upgraded flif to 0.2. My guess is that it was no longer working because metadata was added. Thanks - I guess the reason that it doesn't appear in the git log (http://git.imagemagick.org/repos/ImageMagick/activity) is that you just updated the .h and the .c (http://git.imagemagick.org/repos/Image...

FLIF lib 0.2 update

IM doesn't seem to feature the latest FLIF format 0.2 - images generated by im cannot be read by the Windows Explorer plugin (based on the 0.2 lib), while images converted with flif's own command line encoder can. If so, please update - thanks. https://github.com/FLIF-hub/FLIF/releases https://githu...

Re: How to "best fit" (crop/resize)

Hope someone can help me, thanks You need to somehow calculate the exact part that you want to crop, I'm doing this outside im with a shell script after reading the image props. Then set the gravity % crop this area, then resize. Lookie here under "{size}{+-}x{+-}y": http://www.imagemagick.org/scri...

Re: Versioning policy (Windows installer in-place updates)

This should be possible with InnoSetup. Thanks for looking into it, the current installer oddities don't make im appear like the excellent software it is. At the same time, could you please address another tiresome problem: When in-place updating the Windows installation, the setup asks if it shoul...

Versioning policy (Windows installer in-place updates)

Looking at http://www.imagemagick.org/script/changelog.php the version numbers of im seem completely random - esp. when a change of 7.x.y to 7.x.y+1 occurs or when it's just a 7.x.y-z to 7.x.y-z+1 step. The annoyance is that with a minor version number change, the Windows installers refuse to do an ...

Re: Odd behavior with "-composite" in IM 7.0.3 ?

The requirement for "-alpha on" after "xc:none" seems to be a new bug/feature introduced since 7.0.2-5. Thanks for crossposting to the bugs subforum, as a mere user it's difficult to figure out if it's a bug or one is merely not using im correctly. Even if this change *would* make sense, it shouldn...

JPEG XT

The new jpeg spec can be read by legacy decoders and additionally supports ... * 9-16 bpp int * fp ("hdr") * lossless * alpha (at last!) The libjpeg already seems to have support for it(?), so how about an im delegate for jpxt? https://jpeg.org/jpegxt/index.html https://jpeg.org/jpegxt/software.html...

Re: JPEG XR support question

But apparently all the images are from JPG files, which are then converted to the other formats. What makes you say that, and "apparently". I just assumed that of course the source is a lossless file and then compressed to the various destination formats - it's not like it's difficult to acquire a ...

Re: JPEG XR support question

BPG image format would be great except no browsers support it: http://caniuse.com/#search=bpg Yeah, well, but if *some* windows-only browsers support xr and the rest is WONTFIX, that's basically "none" in real life: http://caniuse.com/#search=jpegxr https://bugs.chromium.org/p/chromium/issues/detai...

Re: JPEG XR support question

It's only useful for IE and Edge browsers Unless you want to use jpeg-xr for intranet websites with ie/edge, maybe you should look at the hevc/x265-based bpg which is an actual step forward and uses the latest and greatest image compression: http://www.imagemagick.org/discourse-server/viewtopic.php...

Re: IM7 regression with "-composite" ?

Is this a bug (& sorry for choosing the wrong forum), or am I missing something and v7 is not meant as a drop-in replacement for v6? Thanks. Almost, but there are some times when using IM7 that you'll have to specify an image has an aplha channel. Thanks, I would have never gotten that idea, it's w...
