Re: Regression: Magick++ truncating multi-page images/animated GIFs

Yes I was using the one from MagickCore, I wasn't familiar with the contents of STL.h. That looks like what I need. So if I'm understanding Magick++ correctly, I want to use a container of Magick::Image to represent multi-framed images, as a single instance of Magick::Image only represents a single ...

MagickCore/blob.c/ReadBlob hangs when reading from Blob created in memory

IM: 6.9.3-8 Platform: Win10, MSVC 14, x64 File: magick\blob.c, line 2851 Using Magick++ and MagickCore, the following code produces what seems to be an infinite hang on line 2851 of blob.c: auto b = Magick::Blob( [image data in uchar*], [size of data] ); auto img = Magick::Image( b ); MagickCore::Ex...

Re: Regression: Magick++ truncating multi-page images/animated GIFs

Hi dlemstra thanks for the response. I tried using ReadImages along with the Magick++ image interface, and magickcore freezes. Same behavior with 3 different input files. I think I've discovered a separate bug deeper in the core; I'll have to report that separately. My psuedocode is roughly: Read im...

Regression: Magick++ truncating multi-page images/animated GIFs

Using version 6.9.3-8. See Magick++ / image.cpp, line 5116: void Magick::Image::read(MagickCore::Image *image, MagickCore::ExceptionInfo *exceptionInfo) { // Ensure that multiple image frames were not read. if (image != (MagickCore::Image *) NULL && image->next != (MagickCore::Image *) NULL) { Magic...

Module tests providing int main()

The following modules are providing their own int main() for testing. These functions are interfering with my own unit tests (via Boost). Environment: IM 6.9.2-0, static link, MSVC 14, Windows. - OpenJPEG / t1_generate_luts.c - libPNG / pngtest.c Excluding these files from the respective projects an...

IM 6.8.7-5, MSVC 12, nearbyint conflict

Hi, Just got VS 2013 / MSVC 12. I attempted to build ImageMagick 6.8.7-5 in debug/64 bit. I received syntax errors relating to 'nearbyint' in math.h, which is possibly a new function in the MSVC std lib impl, since I was able to compile IM without error on MSVC 11. It turns out the function #define ...

Re: MagickCore / CloneImage & Animated GIFs

Thanks, using the STL wrapper appears to be a more elegant solution for my workaround. Is the MagickCore CloneImage behavior, as implemented, the intended behavior? Perhaps I'm wrongly assuming that CloneImage should result in a deep clone of the image (including all of the sub-images in the contain...

MagickCore / CloneImage & Animated GIFs

Hi, I can't seem to be able to fully/deep clone an image that contains multiple images (eg animated GIFs). Looking at MagickCore/Image.c/CloneImage, I see that if the 'detach' parameter is true, it simply drops the additional images in the sequence ( clone_image->next=NewImageList(); ). If the 'deta...

Re: How to deallocate the Image memory

This is more a C++ question than an ImageMagick question. That said, why not put the Images into a std::vector, and clear the vector each time before populating it?

Re: IM Core Enhancements

Regarding OrderedPosterizeImageChannel(), we can define one or two threshold maps in memory, the ones what might be used most often. Do you have a partricular map that you use often? Yes, I'm exclusively using the 1x1 threshold map. The code equivalent is above, here is the relevant xml fragment fr...
