Compiling magick++ for iOS

Dear all, I'm interested in compiling magick++ for iOS. I've already tried a project which compiles the C part of magick for iOS (see https://github.com/marforic/imagemagick_lib_iphone ). To the best of my knowledge, there are no posts/scripts or anything describing that. There is only a report of a...

Re: Memory leaks when creating a simple empty image

Under ubuntu 13.10 with gcc 4.8.1 and magick 6.7.7-10 same program does no leak. I think this is a valgrind issue. ==12023== LEAK SUMMARY: ==12023== definitely lost: 0 bytes in 0 blocks ==12023== indirectly lost: 0 bytes in 0 blocks ==12023== possibly lost: 0 bytes in 0 blocks ==12023== still reacha...

Re: Memory leaks when creating a simple empty image

In which platform did you tested it? Which OS, compiler, etc? I will try to get that version on OSX and see what happens. However, it is not always that easy to get that versions, specially for those relying on package managers like homebrew or apt under linux. I will try to download and compile it ...

Thanks for the answer. This means that these methods are empty shells at the moment?
Best,

Can't modify opacity channel from C++ API

Dear all, Can someone comment on this post? I'm still puzzled at the how steep the learning curve is. At this rate, trying to use Magick++ is almost futile, even though I have a strong background both in image processing and in C++ programming. http://www.imagemagick.org/discourse-server/viewtopic.p...

Re: Can't modify opacity channel from C++ API

I found a way that works. It beats me why, but in this way I can change the alpha channel. Magick::Image* im = new Magick::Image(Geometry(m, n), color_red); im->type(TrueColorMatteType); // magickIm->depth(8); im->modifyImage(); unsigned long p; for (int i = 0; i < m; i++) for (int j = 0; j < n; j++...

Can't modify opacity channel from C++ API

Dear all, My problem is the following, I have an RGBA image with the alpha channel set to 1 for every pixel, and grayscale image. I want to use the grayscale image as the alpha channel for the other one. I was able to do this successfully from command line using -separate and -combine. However I'm f...
