In my opinion, IM -blur does not do this automatically and I do not believe it ever did, since that would need a outward boundary diffusion process. IM does not have any diffusion process and the closest is color morphology dilate (which did not do a good job here from my testing). (Neither did -sp...

Post a link to the exact input images being used on both servers to be sure you don't have two images of the same name, but different non-transparent channels. Upload them from each server. I still find it inconceivable that blurring will change the non-transparent channels from a circle to a round...

I do not see how it is possible to get the change you see for the background under the transparency. Unfortunately, I cannot go back before IM 6.8.6.9 to test. Perhaps one of the other uses might be able to do so and confirm. I can give you a distrib of IM 6.8.0 (if you use windows) if you interest...

And why it's not possible, do you think? It is not possible with a simple blur of a small amount to make the rainbow circle into a rounded rectangle and change the background color from red to black. Either you have two different images or other processing was done beyond a simple blur to change th...

It is not possible to get the background of the second image simply by blurring the first image! Are you sure you are using the same image on both systems. You need to start with the background of the second image with the alpha channel of the first image. Of course the inputs are the same. It's th...

Of course the input image is the same. And why it's not possible, do you think? Even in IM manual said that it must work that way, and you can see the examples here http://www.imagemagick.org/Usage/blur/#blur_channel Photoshop works similiar way blurring with transparency...why do you doubt in that....

Hi, i first made a topic in the main forum because i thought that it was some my misunderstanding, but now it seems more like a Bug Here the topic in Main forum http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=24658 Here is link to manual chapter http://www.imagemagick.org/Usage/b...

Hi again. Yes, I Tried to do this in version of IM 6.6.5 and it works as expected and as written in manual. So it more like a Bug. Maybe i will better post it in a Bugs section. Here the demonstration.. This is Unput files with alpha channel and without https://dl.dropboxusercontent.com/u/84715405/t...

Using: ImageMagick-6.8.6-Q16 64bit Windows 7 64bit I alredy post examples of what i need. I need exactly what in manual examples, i need to blur the edge of image out, but not to mix the colors with transparency color (the way it's said in manual). The purpose is to make antialiasing of sprites that...

That page hasn't been processed with a recent version of IM, and the examples don't work. Perhaps the effect wanted by the OP is, for example: convert in.png -channel A -blur 0x8 -level 50%%,100% out.png This blurs just the alpha channel, then levels it so the only visible pixels are those that wer...

No...no..i don't need yellow circle, it was just a test when i failed to get what i want, then i tried on given in manual example with given pictures and given commandline and still get another result then in manual. The picture in manual also have black background, but have right result, colors isn...

Using: ImageMagick-6.8.6-Q16 64bit Windows 7 64bit First i tried with my images, and when i failed to get what i want, i tried exactly with example pictures and commadlines Here the link to the chapter http://www.imagemagick.org/Usage/blur/#blur_channel Here commandline convert yellow_circle.png -ch...

Hi. I have a purpose to make an edge-antialiasing effect on color images. Here is the example of what i need - http://www.imagemagick.org/Usage/blur/ but it doesn't work this way, if i use channel RGBA it still mixes colors with black, then i've seen explanation that it was a bug and it doesn't work...

Hi, not sure is this a bug or my misunderstanding of some things. Tried to write image in DDS format but there was error " No encode delegate for this image format " and Imagemagick writes zero sized file. I tried -list format and it shows only read support for this format : "DDS* DDS...
