convert memory & time usage

[farmer]

Hi,

I'm using IM 6.4.5-Q8 on Vista, with an Intel Core 2 3.16GHz CPU, and 4GB of RAM.

I'm running

convert -deskew .2 in.tif out.tif

where in.tif has 26 pages, each 2552x4200. in.tif is 1.6MB (with compression=Group4). Whilst running, convert uses about 1.2GB of RAM. The process takes over a minute. Is this expected?

Using Vista's OCR engine, I can deskew *and* OCR the document in less time...

Identify gives info for each page like:

TIFF 2552x4200 2552x4200+0+0 1-bit Bilevel DirectClass 1.561mb

Thanks,
Farmer

Our general recommendation is that if you find a solution that is faster and / or does a better job than ImageMagick, use that solution. However, to answer your question on time and resource usage of ImageMagick, see http://magick.imagemagick.org/script/architecture.php.
