Re: Possible bug IM 7.0.8.54 -alpha shape

Your commands work for us, we get identical results for IMv6 & IMv7. Turn off OpenCL and try again. Did that work? If so it could be -blur giving incorrect results on your GPU.

Re: Problem with FX expression %[fx:n]

ImageMagick is behaving properly. Querying properties requires an image container. In some cases, the user demands a property even if an image is not available so one is automagically created. For example, you might want to perform a FX calculation before an image is read: magick -print "%[fx:.8765/...

IMv6 has deficiencies that we addressed in IMv7. This is one of them. We cannot fix the problem you posted.

Re: SVS: compression not supported

SVS is not supported by ImageMagick. It is a proprietary format wrapped in the open TIFF format. See http://paulbourke.net/dataformats/svs/.

Adding a patch to get exclusive access to the X server resolved the problem, see XGrabServer(). The erran...

The arbitrary channel infrastructure is in place in version 7 series of ImageMagick. We've been looking for use cases (and time) to add the finishing touches for fully-functional multi-channel image support. For convenience, we utilize the EXR delegate library ImfInputSetFrameBuffer() which only ret...
