Great, thank you!

Better late than never! Thanks for your help

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 ...

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 ...

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 ...

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 ...

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 ...

You rock, thanks!

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 ...

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 ...

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 ...

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?

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 ...

Just got 6.8.3-5, the changes are working well. Thanks again!
