Re: resurrecting gigapixel image from 256px jpgs - "unable to open pixel cache" and "too many files open"

We don't have access to your images. We created 96000+ 640x480 images in the JPEG format and as mentioned, the conversion completed without complaint.

Re: Newlines in text files no longer work.

Likely this is a transient bug. We tried your command with the current release of ImageMagick and got expected results.

Re: resurrecting gigapixel image from 256px jpgs - "unable to open pixel cache" and "too many files open"

We run on a Linux system with modern SAS disks. The conversion took just under 2 hours. For Windows, and utilizing the pixel cache on disk, we are not surprised for it to be running this slow. Let it run to completion. If you need to do lots of these, consider switching to Linux and SD drives to inc...

Re: resurrecting gigapixel image from 256px jpgs - "unable to open pixel cache" and "too many files open"

It looks like you have everything you need. The Windows release of ImageMagick supports JPEG and TIFF. The tiff64: prefix to your output filename permits TIFF images that exceed 4GB. Replace -limit memory 8000mb with -limit area 0. We want to force the pixel cache to disk. This is very slow but we n...

Re: Installing Image Magic on the IBMi AS400

Let's see if ImageMagick builds out-of-the-box. Try these commands:

Code: Select all

curl -O https://www.imagemagick.org/download/ImageMagick.tar.gz
tar xvf ImageMagick.tar.gz
cd ImageMagick-7.0.8-9
./configure
make
sudo make install
/usr/local/bin/magick --version

Re: bug converting png to bmp (results in broken images)

The conversion appears to be working properly. It creates a BMP v4 image. Some viewers may not properly handle BMP v4 images. We did check with a few BMP viewers and half of them returned expected results and half failed and returned a black image.

Re: How do I Apply Multiple Screen and Multiply to one image?

See https://en.wikipedia.org/wiki/Alpha_compositing. Associated alpha is premultiplied alpha and the alpha channel is then removed. Disassociated alpha extracts the alpha from the premultiplied channels and restores the alpha channel.

You are not running the latest release of ImageMagick. Type

Code: Select all

magick --version
It should report version 7.0.8-8. If not, upgrade your release of ImageMagick and try your command again.

Re: DestroyMagickWand() assertion fails, application dumps core

Parallel algorithm issues are notoriously difficult to debug. The only hope of addressing this issue would be if we can reproduce the problem.
