Re: Possible bug IM 7.0.8.63 Q16 Mac OSX with JPG output

JPEG checks for grayscale images since these can be stored more efficiently in one channel. You explicitly set the type to bilevel, a grayscale variant. JPEG honors your explicit setting and stores the image as grayscale. The proper fix is to indicate your true intention with this command: magick Un...

Re: .png to .pdf conversion is failing with memory allocation error.

Try this command:

Code: Select all

magick -limit memory 1GiB -limit map 2GiB -define registry:temporary-path=./ 001_25.png -density 200 x.pdf
Does that command work for you?

Re: Bug converting PSD to TIF with alpha

Adding '[0]' to your input image name returns the PSD composite image. It does not include an alpha channel. Remove the '[0]' and you get the image layer which does include the alpha channel:

Code: Select all

convert input.psd output.tif
identify -verbose output.tif | grep -i Alpha:
Alpha: 1-bit

Re: Change DPI while keeping resolution

Standard TIFF file is limited to 4GB. The bigtiff delegate library can write BigTIFF files, which contain 64-bit offsets to directories and image data. For a BigTIFF file there is no practical limit to the size of a file.

Re: Possible bug IM 7.0.8.60 with resize, attenuate and noise

First, see https://imagemagick.org/script/porting.php: If you see differences in the results of your version 6 command-line with version 7, it is likely due to HDRI. You may need to add -clamp to your command-line to constrain pixels to the 0 .. QuantumRange range, or disable HDRI when you build Ima...

Re: Possible bug IM 7.0.8.60 with resize, attenuate and noise

We're getting expected results. We assume you have a GPU? If so, there might be a bug in the OpenCL GPU acceleration code. Grab ImageMagick-7.0.8-63 and add -debug accelerate to your command line. Post the output here so we can trace which accelerated method might be failing.

Re: Cosine-sum filters for resampling

We do include a Hann filter, a member of the cosine-sum family, however we do not currently support the generalized cosine window case. You are welcome to contribute a cosine-sum filter. Look for FilterFunctions in MagickCore/resize.c to get started.

Re: ImageMagick no longer maintained for iOS?

The ImageMagick developers do not distribute an iOS release of ImageMagick. Instead an ImageMagick user, ~Claudio, contributed build scripts. You may be able to leverage the scripts to build the latest releases of ImageMagick. You can also try to contact him to see if he will update the build script.
