Re: convert output changes with recent update

A recent ImageMagick update (to version 7.0.8-47) on my system has resulted in production of errant results from a script I've been running for a few months now. The script overlays onto an image some text that I download from the internet at regular intervals, adding a blurred shadow effect to the...

Re: Problem with -blur on transparent with 7.0.8-47

Convolution in IMv7 had a bug when dealing with alpha channels. The bug is fixed in -47. The bug I'm describing just appeared in -47. Using -channel RGB tells IM to ignore the alpha channel when blurring. It should, as Fred suggests, fix the problem you reported. Using "-channel RGB" before the blu...

Re: Stacking two image series

My current work around: Use ffmpeg to create separate animations for each image series and then stack the animations using ffmpeg again. Any advice regards where my thinking is wrong is very much appreciated. EDITED TO ADD: Apparently I misunderstood the question, so I edited out my previous answer...

Re: Removing All Shades of Grey from an Image

After more testing I realized that I can't entirely drop the black channel from the CYMK separation. [...] To my novice eyes, adding a second +clone line and fuzzing the K-channel to a few percentage points of #000000 would work, but I'm not sure how to pull that off and then combine both into the ...

Re: Annotate is repeating on every image.

The blocks are white (FFFFFF) for example, in reality, I'll use different colors, but for simplicity, I'm using FFFFFF here. I need the first and second block to only print 1 and 2 respectively without having other numbers written on top. When using "-annotate" you can include FX expressions within...

Re: PNG file manipulation

montage sucks because it requires I have 9 identical files in the working directory, so my script generates them and then deletes them after the montage command. The other solutions offered above are good. Here's another pretty simple idea to make a 3x3 tiled result from a single input image... con...

We can make it slightly faster (and use less memory) by separating just the CMY channels, rather then separating them all then deleting the K channel:
Thanks. I noticed that and was editing probably as you were replying. :)

Re: Removing All Shades of Grey from an Image

I've been hitting the google books and am trying to figure out how to remove all shades of grey from an image. (ie preserve all "colors") There are several ways to approach this, and some very good solutions have already been provided. I worked from a slightly different direction. This uses a mask ...

Re: -compose Multiply not wroking with RGBA files

I was trying to use: magick composite "pattern.png" -compose Multiply "green.png" "mrp3.png" what is wrong for RGB channels, only alpha channel has correct A amount, than I tested if it would work for only grayscale and for only one channel( R ) and it worked, as expected.

Re: Percent Escapes with Extent

Is it possible to use percent escapes with the -extent option? I would like to swap the width and height of an image, but keep everything else the same. As mentioned, the FX expressions are most versatile using IM7, but it can be done with IM6 using "-distort" and setting a viewport. Try this... co...

There are many tools . You're probably trying to: magick convert source_filename.tif -resize 27071x18702! new_filename.tif Unless there is a specific need to emulate the behavior of IM version 6 you should not use "magick convert". Just use "magick" for IM version 7 to take advantage of the improve...
