we are using IM6.7.9-3 in our system. And we noticed that while doing the encoding of webp there is a memory leak. Then we turn to 6.8.3.4, and the memory leak bug had be fixed. But there is a new problem, when convert a gif or a bmp image to webp, it failed with "NoDecodeDelegateForThisImageFo...

I have one bmp image can't be resized. But it can be viewed in windows. /usr/local/ImageMagick-6.7.0/bin# ./convert -sample 40x40 441.bmp 1.jpg convert: invalid colormap index `441.bmp' @ error/colormap-private.h/ConstrainColormapIndex/34. http://ice.qq.com/images/441.bmp Something wrong with this i...

I know ping(), but I don't know how to decide which one is too large. It should depend on the memory used by IM. If it consume more then 1GB, I think it's too large. So is there some formula to calculate the memory used by IM for one image approximately? For example, the image's dimensions is 5000*4...

I used ImageMagick-6.7.0 to resize lots of pictures and got one large exceptional picture. It's about 2.7MB. To resize it, Imagick++ used about 1.5GB memory. Of course, to ensure large images do not consume all the memory on my system, I can force the image pixels to memory-mapped disk with resource...

It has nothing to do with the syntax. I had try it. I also have this problem when resizing PNG and BMP. Isn't the newer syntax "convert 102.jpg -scale 500X500 result.jpg"? Not that this is likely your issue. http://www.imagemagick.org/Usage/basics/#why Do you have this problem when using a...

ImageMagick version: 6.3.0 I installed it under different linux os , one is SUSE-Linux(gcc version 4.1.2 ), the other is slackware-linux(gcc version 3.3.4). After install ImageMagick-6.3.0 in two computers, I used command "./convert -scale 500X500 102.jpg result.jpg " to resize my picture....

Dear Drarakel, it works, thank you very much!

By the way, for CMYK pictures in such cases, use a generic SWOP profile, Dear administrators, why don't you put USWebCoatedSWOP.icc file into "http://www.imagemagick.org/download/del ... ofiles.zip"

After converting, the image's colorspace is still CMYK. Other photos could be convert successfully, only this photo failed. How to convert the "sepecial" photo ? ~/ImageMagick/bin$ ./convert file_4.jpg -profile SRGBSPAC.ICM 1.jpg ~/ImageMagick/bin$ ./identify -verbose 1.jpg | grep Colorspa...

thank you very much~
By using both of the functions as follow, the gif image size was reduce.
thumbnails = OptimizeImageLayers(thumbnails, exception);
OptimizeImageTransparency(thumbnails, exception);

"Lets now use the "-layers", method 'OptimizeTransparency' (Added IM v6.3.4-4) to replace any pixel that does change the displayed result with transparency. " see: http://www.imagemagick.org/Usage/anim_opt/#opt_trans By using "Transparency Optimization", the gif file si...

thank you for your answer.
So Is there any method for me to deal with these pictures using IM ?

It's a GIF image file. when IM opens it, it throw the exception "e=ImageMagick: Corrupt image `2AD9A180-F37A-459F-B056-A4C71CE31445.gif' @ gif.c/ReadGIFImage/1316"
So, it's a corrupt image, but it can be viewed and edit under widows xp.
