Loading PNG Image Problem

Magick, I have a PNG Image, which may have some issue. I have been able to load it with IM before. But I have problem in IM7. The ImageMagick loaded it with a error message "Read error at scanline 4294967295; got 4529 bytes, expected 4560. `TIFFFillStrip' @ error/tiff.c/TIFFErrors/572", and exceptio...

Re: Linking VS2010 with ImageMagick

it looks like this is the reference problem. You probably called "delete blob" in your ~Texture(), if I remember correctly, ImageMigick doesn't export destructor of Blob object. You may need to call DestroyBlob(Blob*) to release the object.

possible memory leak in cairo?

Magick, I am no familiar with Cairo, my vld tool report there is memory leak in imagemagick-6.8.8\cairo\src\cairo-image-surface.c (181): _cairo_image_surface_create_for_pixman_image. I checked that chunk source code. cairo_surface_t * _cairo_image_surface_create_for_pixman_image (pixman_image_t *pix...

Re: j2c extension support

I use IM directly to process. I did step by step debug yesterday, and pretty sure it called j2k decoder from openjpeg. Originally I have problem with J2K file. After hours debug, I finally found out that my j2k file actually is the jp2, which has box header. IM only check file extension or ImageInfo...

j2c extension support

Magick, Is it possible to add the j2c extension into IM? It basically is j2k. right now, I checked the j2c extension myself, then set ImageInfo->magick to be "J2K". It worked, but if you can add it in IM that will be great. Example file can be found at: https://github.com/bitsgalore/jp2kMagic/blob/m...

Re: strange memory leak report

I did a little bit research on this issue. It looks like Glib will release its memory block at the exit time, which probably after the vld memory check and _crt call. If that is the case, those memory allocated by Glib would be considered as leak. I read into Glib source code, it seems like Valgrind...

Re: Report a problem when processing large jp2 image.

I am using ImageMagick-windows which is 6.8.4, it has commented out the tmpnam and replaced with that strange _snprintf().
