Converting tif files with mogrify is taking ages.

[skirk1983]

Hi,

I should convert 160 tif files with these properties:

Dimensions: 1275x1753
150x150 dpi
Depth: 8 bit.
compression: LZW

to tif files with these properties:

Dimensions: 2496x3507
300x300 dpi
Depth: 1 bit.
compression: CCITT T.6

I'm trying to convert on 10 tif files with this mogrify command: mogrify -resize 2496x3507 -monochrome -compress group4 -density 300x300 *tif.

I have tried to run this with the ImageMagick 64x dynamic version on a windows 7 x64 client, but it frozed the computer. I think it used all the memory of 4 GB. I could not use the computer because it was extremely slow. Of the 10 tif files some is 14 mb large.

Should this conversion not be possible? What are I'm missing here?

Please help.

You are probably running out of RAM. see http://www.imagemagick.org/Usage/files/#massive
