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.

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

This is expected behavior. Instead try this command:

Code: Select all

display -colorspace sRGB image.heic

Re: support for raw 16-bit RGB565

Assume 8-bits per pixel, so -depth 8 is required. Even so, with a width of 800 pixels (e.g. -size 800x600), thats 2400 bytes of RGB per scanline. With a file length of 960000, the pixels are consumed after 400 rows, although you are asking for 600-- thus an exception is thrown. How many rows and col...

-48 will be released today. Nudge Arch to upgrade or build -48 from source.

Re: Work with object...

With PerlMagick you can read an image, resize it, and get the pixels all in memory. See https://imagemagick.org/script/perl-magick.php for example PerlMagick scripts.

Re: Problem with -blur on transparent with 7.0.8-47

Convolution in IMv7 had a bug when dealing with alpha channels. The bug is fixed in -47. Using -channel RGB tells IM to ignore the alpha channel when blurring. It should, as Fred suggests, fix the problem you reported.

Re: Resize to large destination slows down at 33%

Use -scale rather than -resize. Resizing is a two pass process that causes ImageMagick to read pixels in a non-optimal manner, column-wise rather than row-wise. That's fine for memory, but as you found, very slow on disk.

Re: convert: data storage type is not supported when opening a gimp 2.10 xcf image

Not a bug. ImageMagick is behaving properly. It does not support high bit-depth images exported by Gimp 2.10 and alerts you when you try to read the image. Two solutions. One, save your image in the Gimp 2.8 compatible format or wait for a patch to the XCF reader in ImageMagick. We do not have an ET...
