Legacy ImageMagick Discussions Archive

Thanks for your help anthony and fmw42. I've now played around with this a little. One thing that confuses me is that the -dissimilarity-threshold option of compare doesn't seem to have much of an effect: compare -subimage-search -dissimilarity-threshold X% original.png search_image_flat.png result-...

Hi, I have something I'd like to do with ImageMagick, but I'm not sure where to start, or if it's even possible. Given a source image , for example like this: http://img41.imageshack.us/img41/8579/originalsa.png ... and a " search image ", for example like this: http://img820.imageshack.us...

After upgrading to ImageMagick 6.6.9-4 2011-04-11 Q16, it works as expected now. Great!

That probably always worked, the problem was only with images with width ≤10px and height ≤ 25px (at least for me).

I might be hitting the same bug (also using ImageMagick 6.6.9-1). In my case it doesn't replace transparent pixels with black, however, but rather with the "Alpha" background color saved with the image: bullet.png http://img860.imageshack.us/img860/4299/bullet.png $ identify -verbose bulle...

Hi, the "Over + ChangeMask" solution still seems to have issues after all. (Well, they might not be issues for other people, but for my use-case, they're problematic.) For example, given below is a real-life example of my use-case (well, real-life plus -sample 1000% plus black border ). Th...

Thanks, anthony! Your solution works great: http://img204.imageshack.us/img204/5789/sourceup.png + http://img163.imageshack.us/img163/576/backgroundtv.png --> http://img827.imageshack.us/img827/2451/outpute.gif Also thanks for including the "without parenthesis" version, as that really hel...

your final example results seems to indicate you are wanting to define the background of a GIF image that only has boolean transparency, in termes of a web page background. That is you want to replace semi-transparency with an appropriate opaque color blend, while keeping fully-transparent transpar...

Ok, after more experimentation, I did manage to get it to work after all... (At least for the sample images I checked with.) If anybody knows if there's a better way to do this, or if it can be written in a more compact form (maybe a single console command instead of three?), then please tell. -----...

Hi all, how would one semi-flatten a PNG image against some background image using ImageMagick? I.e. blend a partially translucent source image over a background image, but only let the background image shine through on those pixels where the source image has an opacity greater than 0 . (Fully trans...

I can only see the second example. I cannot access the first. You can see here, for example: http://nexus404.com/Blog/2010/02/09/google-buzz-takes-a-hit-at-twitter-never-to-replace-them-what-is-google-buzz-why-do-i-need-it/ (As you can see, this example actually *only* shows a bottom shadow) I saw ...

One more question: If I wanted to add a soft bottom shadow, as for example in http://mail.google.com/mail/buzz/img/interstitial_page.png http://www.inloox.com/var/corporate_site/storage/images/media/images/coverscreen/9251-2-eng-GB/coverscreen_large.png a -draw "ellipse ..." with a -blur a...

Hey, thanks a lot!

This has been done before and posted in IM. Search the archives. I tried, but can't seem to find anything (other than what you quoted)... Maybe I'm searching for the wrong keywords... Does this effect have an official name which I can use to search for it? For example http://www.imagemagick.org/dis...

You know, the one that commercial companies like to use to present their software products... The original screenshot is always tilted by a small amount in 3D-space, and shows a smooth shadow and reflection. Here's an example: http://www.softmaker.com/english/ofwtm_en.htm Has anyone had any luck imp...
