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/.

Re: "import" blocking keyboard I/O

We received a couple of reports where the drawing rectangle that defines the area to import was not rendering properly. Errant lines would persist as the rectangle was dragged across the screen. Adding a patch to get exclusive access to the X server resolved the problem, see XGrabServer(). The erran...

We were about to investigate this issue but you saved us the time. Looking forward to your PR.

Re: Possible regression reading DPX files

Can you post a link to a DPX image that throws this exception? We need to reproduce the problem to determine why the exception is thrown and determine if there is a bug or if its a security issue.

Re: Multi-channel EXR support in command-line

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...

Re: Animate crashes my computer

The animate program loads all the frames in memory and likely thrashes your system. You can reduce memory usage by forcing the pixels to disk:

Code: Select all

animate -limit memory 0 -limit map 0 6b48cf22e4c7d62.gif
For your use case, try firefox or ffplay instead.

Re: Export Speed with ImageMagick

By default, ImageMagick supports HDRI which requires floating-point pixel components. If you build ImageMagick without HDRI support (add --disable-HDRI to your configure script command-line), you get unsigned pixels and will likely result in a substantial speed-up.

Re: Tiff tags are missing in newest version

Add -density 300x300 to your command-line, for example, to export the image resolution.

Re: DICOM file detected incorrectly on versions above 6.9.7

We compared the ImageMagick rendering of your image against what is returned by XMedCon and got similar results suggesting the current ImageMagick rendering is correct and therefore bug free.

Re: Possible bug bad xmp profile

Unfortunately, we cannot reproduce the problem. Try with the latest Beta release of IMv7 -50. Post the exception so we know which line exports the warning. Also post the output of `convert --version`.

Re: DICOM file detected incorrectly on versions above 6.9.7

Modern releases of ImageMagick exports unadulterated pixels. If it is proven that the pixels values are not the expected results, we will investigate further.

Re: DICOM file detected incorrectly on versions above 6.9.7

Try this command:

Code: Select all

convert test.dcm -normalize test.png
The pixels appear to be 12-bit signed pixels but the file meta data says its 16-bits (add -verbose to your command-line to confirm). Normalization expands the 12-bits to the full 16-bit range

Re: [PATCH] display command does'nt change colorspace to sRGB if needed

ImageMagick has a hands-off philosophy. We assume the user knows what they are doing so we don't touch the image attributes, including the colorspace, without an explicit command-line option.
