Hi everyone,

Iam new to image magick can anyone please help me in this ....


I want to read images of format .svs exetension. the image have dimensions of 60000x30000 and its size is nearly 100MB. can we read images like this using image-magick.

Thanks in advance.

Try the following command:

• convert 'CMU-1.svs[3]' CMU-1.png

It works without complaint.

SVS is really just a pyramidal (multipage) TIFF file. You can see the pages and their dimensions using the identify command. ImageMagick can read most of them, but we've found the newer ones use JPEG2000 compression and cannot be read with libtiff.

If you want to work with the largest image in an SVS file of that size (60000x30000), vips might would work better since it doesn't read the whole thing into memory.

what is vips...?Can u please explain..?

VIPS is one of many open-source image processing solutions. Its an alternative to ImageMagick like NetPBM, Gimp, etc.
