We need to investigate this problem further and get back to you.

In most cases, the only way to speed up ImageMagick is to run on a faster processor or add more memory or limit the size of the input image. The cost of processing of an image is directly related to the area of the input image. You can speed up JPEG thumbnail creation by adding the -size option to t...

Your example.psd image does not appear to have any text associated with it. ImageMagick 6.2.6-3 renders it the same as Gimp does.

Your script should work in identifying corrupt image files. An exception is returned if the file cannot be read.

To only convert one frame from a multi-frame image, use this command for example:

• convert 'image.tif[0]' image.jpg

Post a URL to your original PSD image so we can reproduce the problem and come up with a solution.

Grabbing X windows can be quite complex because the windows are stored in a tree structure and to ensure you are getting a proper image you must composite the entire tree structure onto an image canvas. However, if you are sure your image can be obtained directly from the screen, you can short cut t...

Hexcode is the window id, for example,

• convert x:0x1a0001f window.png

MagickWand has the MagickSetImageMatte() method which sets the image opacity channel to completely opaque.

You can read an image from a X window with X coder. From the command line:

• convert x:mywindow window.png

where mywindow is the window name or hex identified. From Magick++, just do a Read() with x:mywindow as the file name.

We know little about MagickWand for PHP. Mr. Watson, the author, has a new release nearly ready but has been distracted by life/work. We'll send him a ping and see if we can get him back online.

There is a light-weight method for determining the image type before you read it, MagickPingImage().

Use MagickSetResolution() to specify which resolution to render Postscript or PDF image files.

For a preview of JPEG compression at different quality settings, try this command:

• convert myimage.png -preview jpeg preview.png

Net11 failed to response to our support requests so we formally dropped Net11 as an ImageMagick sponsor. However, they did not even respond to our request to drop the service so the machine appears to be a zombie right now. So you can safely remove the Net11 link.
