LZW compressed TIF to JPG

brixion · Post by **brixion** » 2009-06-30T05:26:10-07:00

Hello,

I have an LZW compressed TIFF file that must me converted to an JPG image.
But everything I try results into an JPG image with only black content.

When I inspect the compressed image, IM can see all the details, even the histogram.

What did I do wrong?

Post the verbose identify output for your JPEG image. Is the histogram similar to the one returned for your TIFF image?

Yes the JPG histogram quite matches the TIFF histogram.

What goes wrong?

Post a URL to your original TIFF image. We need to reproduce the problem before we determine why this conversion is failing for you.

Hope you or your team can find the problem

We converted your TIFF image to JPEG and got the expected result, both images are identical (except for the slight differences due to the JPEG DCT transform). We're using ImageMagick-6.5.4-1, the current release. In addition, we are using LIBTIFF, version 3.8.2, and JPEG 62. We are not sure why the conversion is failing for you.

I'm using the following configuration:

I think i'm missing the libtiff library. I have to ask my webhosting provider to install it for me. Then I'll try again.

Thanks for the quick response!!

I tried to convert it to GIF and PNG as well, but they also turn into a black image. Very strange... would the difference be in the IM version 6.5.4-1 (you) and 6.5.1-10 (I use)?

Post by **magick** » 2009-06-30T08:38:02-07:00

You could always try 6.5.4-1 but perhaps your version of TIFF does not support LZW-compression. However, if so it should have reported a warning. Right now we do not know why the conversion is failing for you.

brixion · Post by **brixion** » 2009-07-01T00:36:08-07:00

Thanks for your help... I'll update my server to 6.5.4-1 and then I'll let you know the result.
