Legacy ImageMagick Discussions Archive

Indeed, I remember when we first broke a terabyte... we had a really compact system that only required two full racks to do it! ;) These days my paltry 20 terabytes is one small corner of our aggregate server storage (over 2 petabytes at last count, most of it flash...)... It's big enough for IT to ...

It's a very diverse archive, there are 1 bit, 8 bit, and 16bpp images in the archive. I suspect the 1-bit images are about as small as thier going to get already in TIFF LZW, 27% disk savings on the other images is not insignifficant when we're looking at over 5 million images, but then again disk ...

Hi! i have a large-ish image archive (many terabytes) that is currently in TIF format, I've just recently gone though it and made sure everything is LZW compressed, which saved several terabytes, but I'm wondering if there is a way to estimate the image size when changed to a new format -eg ...

Ok, so i have a situation where i would like to ideally do the following: I have a known pixel value width (not the same for every image, but known) and a text string of variable length, not more than 15 characters, not less than 3. I have quite a bit of freedom on height (although it is ultimately ...

Thanks! This solved my problem with a cygwin build of 6.8.5-8 too!

Currently running 6.8.5-6 2013-05-10 compiled from source on Ubuntu 12.04

update: just downloaded and compiled 6.8.5-8 and it works a charm! Thanks!

Ok, so I'm trying to do this with a miff stream for expediency, but if I have to write out temp files it won't be the end of the world, i'll just put that up front ;) so, basically this is the psudocode i'm using (there's more to it, but these are the relevant bits...) : for f in $* do convert -size ...

Thanks for the hints guys! By carefully optimizing my match image for the crop marks, scaling to 10%, and further subdividing the search area I have cut down the process time per image (including rendering a 300dpi anti-aliased tiff from my PDFs!) to about 45 seconds average per image. My script ...

Thanks! I'll try the 10% reduction, it should still be useful at that size... how do you then search in a defined area for tighter match?

The crop marks are the same SHAPE and nominally the same color (black, as defined by the color space of the image, on a nominally white background, though sometimes it is emulated paper white, not color-space white), but size is not identical as the scale of the entire page is variable. I don't have ...

Ok, so here's the scenario: I have a large archive of PDF files (1000s of pages). These PDFs have *NOT* been built with cropbox, trimbox, etc defined (le-sigh). Some pages are RGB, some 8 bit gray, some mono, some CMYK, just to make it more fun! The geometry of the desired content is variable, as is ...
