thank you magick.

hi all,

Why process like GetImageEncoder() and GetImageDecoder() need to be mutex protected if no thread_support?

hi maigck, I have a question about zooming gif with MagickWand API. I have a gif. I want to do resize on its first frame. I want the output is jpeg. So I do these: MagickReadImageBlob() MagickResetIterator() MagickResizeImage() MagickSetImageFormat("jpeg") MagickGetImagesBlob() Then the pr...

I have noticed that there is another MagickSetImageColorspace/MagickGetImageColorspace which can do this for me. My problem solved. So now my question is this: what's MagickGetColorspace/MagickSetColorspace used for?

hi magick,

I'm using MagickWand API now. I have checked the code. MagickGetColorspace() will get colorspace from ImageInfo, but after decoding, only Image.colorspace will be set. So Magick::Image::colorSpace() can get the right value but MagickGetColorspace can't. Please help me out. Thx.

thank you snibgo!

hi I found these files in my "/tmp" dir. What are they used for? I'm using Magick++ from ImageMagick-6.8.5-4. -rw------- 1 admin admin 165M Jun 25 12:48 magick-2152jhe_NTn1xZt4 -rw------- 1 admin admin 176M Jun 22 14:41 magick-23251ngwAdvFZTZbO -rw------- 1 admin admin 176M Jun 24 13:09 ma...

hi, magick

I noticed that new version IM use GetImageArtifact() instead of GetImageOption() in some place(linke codes/webp.c). But defineValue() in Magick++ still use SetImageOption(). So how to set image option now?

$ ./Magick++-config --ldflags
-L/home/path/to/ImageMagick-6.8.3/lib -lMagick++6-Q16 -lm -lMagickCore-6.Q16

should be -lMagick++-6.Q16 instead of -lMagick++6-Q16?

hi, magick

I'm sorry. It's

hi, magick I'm working on observing our production system's memory leak problem recently. Unfortunately I found another memory leak in ImageMagick. Although it's not a big deal, I still put it here to let you know. Again, it's a corrupted png. It also exists in early version like 6.2.8. I noticed th...

hi magick,

Thx for rapid response. Here is the corrupted jpeg file.

hi magick, I noticed that there is another memory leak about freeing the memory allocated by ExceptionInfo. When image->exception is thrown, the following DestroyExceptionInfo will not be executed, thus lead to the leak. I've checked the src code of 6.2.8 and this is right there. Should be you guys'...

hi magick, we are using IM6.7.6 in our production system. And we noticed that while doing the encoding of webp there is a memory leak. I've checked the latest version(6.7.9-7) and finding that the problem still exists. Following is the patch, pls check it, thx. Index: coders/webp.c =================...

Thanks for rapid response. One more questions, how can I find all available options that I can set using the method defineValue. I have a special requirement that need to zoom using the minimal dimension. I had tried "^" in the geometry string but it didn't work. so I turned to using anoth...
