Thanks, the correct escape characters made the trick.

Re: Some thoughts on antialiasing and clipping paths

Ok I have tried this now in Windows and it seems to work except that the resulting image is negative. I guess it has something to do with the ( - -negate ) part of the command. I have never been able to have the ( ) work in the command line, not with \( \) either. If I after the process run just the...

Re: Some thoughts on antialiasing and clipping paths

I'm working on a plugin for a system that can work on both Windows and Mac. For the Windows version I can embed IM standalone but for Mac I haven't been able to create a working standalone version so in the case of Mac I will recommend the users to install IM via Brew, so that would be version 6.9 o...

Re: Some thoughts on antialiasing and clipping paths

Ok, that's kind of positive but this has to work on both Mac and Windows.


Edit, I just saw that Inkscape is available for both plattforms. I haven't heard about Inkscape before :oops:


Thanks

Re: Some thoughts on antialiasing and clipping paths

Here is an example on the different results from this example: identify -quiet -format "%[8BIM:1999,2998:#1]" test.tif |\ convert -quiet test.tif \( - -negate \) \ -alpha off -compose copy_opacity -composite \ -define tiff:alpha=associated \ result.tif I have made the background white to show the ef...

Re: Some thoughts on antialiasing and clipping paths

Yes I have tried both of them and it is a big difference between the result in IM and doing it in Photoshop with anti-aliasing. The method you suggest is OK but the edges get blurred and are not as sharp as they are in Photoshop. And this gives a quality reduction in the images. The difference is ve...

Re: Some thoughts on antialiasing and clipping paths

Well, I don't consider this as a specific question but rather a thought on if this is even possible to achieve since I haven't found any good procedure on doing anti-aliasing on clipping paths. And in this case asking for IM versions or platforms is kind of secondary IMHO. All of the so far suggeste...

Some thoughts on antialiasing and clipping paths

I have some questions on this topic if it is possible. An image with a clipping path needs to use the clipping path to get rid of the background outside of the path. I can do this with a few methods but I don't get the crips edges that Photoshop offers since there I can add anti-aliasing to the path...

Re: Difference between composite and convert -composite BUG??

That only gave me the mask in the output.

The solution you suggested in the my other post is working and could may be improved a little.

Re: Anti-aliased clipping path

I did as the example in the post and it got a little better but there is still more jaggines than with Photoshop. This is the syntax I used identify -quiet -format "%[8BIM:1999,2998:#1]" input.jpg | convert -quiet input.jpg ( - -negate ) -alpha off -compose copy_opacity -composite output.psd There i...

Re: Difference between composite and convert -composite BUG??

Well if it the transparent file that controls this then it explains it. It is created on the fly with ImageMagick to get the same size as the original file. It doesn't contain any ICC-profile or paths and I guess that also explains the resolution. Is there a way to copy the path from the input file ...

Re: Difference between composite and convert -composite BUG??

Thanks for the clarification, my mistake.

How ever doing it like you suggest discards the ICC-profile and the Clipping path, shouldn't they stay?
Another thing is that it shows that the resolution is only 1 px per inch.

Difference between composite and convert -composite BUG??

When using the command composite to save a transparent Photoshop file I get a different result than with convert -composite. With composite I get the proper result of a PSD file with a transparent background. The command is: composite input.jpg transparent_file.tif mask.jpg output.psd Only drawback ...

I have a programmer that will try to solve this but he is very busy and can't take it on until a month or so.

Anti-aliased clipping path

I'm working on a project that will receive hundreds of images with a clipping path. Each image will be saved in one version as a JPG with a white background and as a PSD with transparent background. When using IM to clip the image I get a very jagged result where the clipping path is, very much like...
