Hi,

I want to convert some large images into ppm/pgm format. However, I encounter the following problem:

C:\Program Files\ImageMagick-6.2.6-Q16>convert balloon.jpg balloon.ppm
convert: unable to extend cache `balloon.jpg': No such file or directory.
convert: Application transferred too few scanlines `balloon.jpg'.

On smaller images, it works fine. balloon.jpg is a 16000x12000 24BPP image. It's about 7mbs in size.

Thanks for any help,

We have a lightweight program to convert large images we're getting ready to release, but in the mean-time ImageMagick requires copious amounts of disk space to process large images. It's possible you are running out of disk space or you are running on a FATS disk and ImageMagick wants to create a temporary disk file greater than 4GB. For that you need NTFS.

Thanks for the quick reply.
When is the expected release date for the lightweight program?

The program is called stream and we're not sure when it will be released, perhaps in a month or two. We could post the source now but its completely untested and we're not even sure it works properly.
