How to set encoding options for bpg delegate?

Fortunately, recent IM seem to feature the bpg format (if the bpg binaries are found) which I'd like to use instead of png for internal viewing purposes. But apart from setting image.bpg as the output ... ... how to I tweak the encoder, i.e. funnel command line options from IM to the bpgenc.exe? The...

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...

IM7 regression with "-composite" ?

This works on version 6, the wizard is added to the canvas just as expected: convert.exe -size 800x800 canvas:transparent wizard: -composite wizard6.png The same command sequence fails with version 7 (ImageMagick-7.0.3-1-Q16-HDRI-x64-dll.exe or ImageMagick-7.0.3-1-Q8-x64-dll.exe) ... the output is j...

Re: jpeg2000 status and optimization

Indeed, that's what google imagemagick jp2 turns up, and the options are so basic I neglected to quote the link :-p ... thus the question if anyone knows if a smarter compression is implemented anywhere, see my link to the research pdf above.

jpeg2000 status and optimization

I thought the jpeg2000 standard is dead for practical use with joe sixpack as no web browsers or many meaningful viewers can handle it. That is until I discovered that pdf supports it, i.e. for a batch of pictures I now put them inside a pdf as jp2. For my photography, this results in a noticeable c...

Req: -define jpeg:extent for jpeg2000 (and other lossy formats)

I'm using the latest im7, and it seems the upper file size limit (-define jpeg:extent) indeed only works for jpeg images. As far as I understand it, this option just initiates a dumb trial-and-error to find´the compression that matches the requested filesize? If this isn't specific to the jpeg compr...

Re: How to tint image to dominant color?

Inside the second set of parentheses it makes an 8x256 white-black gradient image. Then it sets the fill color to that variable we made from the 1x1 color pixel above. Using that fill color it tints the 8x256 gradient strip. Before exiting that set of parenthesis it has to rotate the 8x256 image 90...

Re: How to tint image to dominant color?

What is your IM version and platform. Please always provide that information. Sorry, I'm running Windows x64 with im7 q16 hdri It depend on what you mean by "dominant colour". This might be: convert scale 1x1! info: (Adjust as required for your shell.) A shell script can pull the colour (eg #123ABC...

How to tint image to dominant color?

I'd lke to do something like sepia-tone, but automatically set the tint color to the dominant color of the image (before converting to grey and tint). For example if it's an image of grassland, I'd like to get a grey->green-tint'ed image, if it's sky it should be grey->blue tint. What I need is... a...

IM7 -format usage [DELETEME]

... doh, found out for myself that im7 magick.exe is not drop-in for im6 identify.exe :-\ - please update http://imagemagick.org/script/escape.php to state that the specified identify.exe syntax no longer works.

Re: Module "img2knl" missing from (all) Win builds

img2knl is one of my proccess modules. These are not part of the official distribution of ImageMagick. Right, I didn't get that, thanks for explaining. Any reason for not including this into the vanilla IM distro (yes, I probably could dig up some old threads)? Let this please be a +1 for this modu...

Re: Suggestion: "too low Quantum" warning

In principle I think it's a good idea. But working out the practicalities is hard.This ties into a wider issue that I've always wanted: a "lint" processor within IM that would tell a user, "Your command is legal, but probably not what you want." The practicalities of this are also hard. Ok, fair en...

I was trying to experiment with the seemingly nice lens blurs from http://im.snibgo.com/camblur.htm, but to no avail: On all Windows builds (I've tried IM6 q8, q16 dll and q16 portable, and for good measure the bleeding edge "all included" im7) this module seems to be missing.

Re: Suggestion: "too low Quantum" warning

It probably would concern many operations. Interesting, so that would make a warning even more useful than I imagined as Q8 is such a severe downgrade to iq and unknown to a lot of ppl. Currently, (at least for me, ymmv) it's very hard to get an idea when Q8 can be used for speed at all w/o any doc...
