convert tiff to pdf

[grepi]

Hello,

I' m working on macosx 10.5.7 intel with fink and have to convert tiff to pdf files:
i imagemagick 6.4.1-1013 Image manipulation tools
i imagemagick1-dev 6.4.1-1013 Image manipulation tools
i imagemagick1-shlibs 6.4.1-1013 Image manipulation tools
i imagemagick1-svg 6.4.1-1013 Image manipulation tools
the file to convert in pdf is:
tiffinfo Gears.tif
TIFF Directory at offset 0xa8c08 (691208)
Image Width: 480 Image Length: 480
Resolution: 1, 1 (unitless)
Bits/Sample: 8
Compression Scheme: None
Photometric Interpretation: RGB color
FillOrder: msb-to-lsb
Orientation: row 0 top, col 0 lhs
Samples/Pixel: 3
Rows/Strip: 5
Planar Configuration: single image plane
DocumentName: Gears1.tif
Software: ImageMagick 6.4.1 01/29/09 Q16 http://www.imagemagick.org

convert Gears.tif Gears.pdf

generates a black image Gears.pdf

OK let's try a newer version ImageMagick-6.5.3.

convert Gears.tif Gears.pdf

generates a white image Gears.pdf.

Convert can not handle "Resolution: 1, 1 (unitless)" Tag. This Tag should be ignored on converting tif to pdf.
The pdf should be computed by image length and image width.
Please update convert, it has a silly programming error.

Cheers,
grepi

Can you post a URL to your image? We need to download it and reproduce the problem before we apply a patch.

Hi,

the image was generated by pixie with

rndr gears.rib.

all pixie images are generated in this way.

We need to reproduce the problem before we can offer any help. Can you post a URL to Gears.tif so we can download it and use it as reference image for the problem you posted. Thanks.

Hello,

here you have a 10x10 pixel tiff image in compressed ascii form. I don't like running my mac round the clock and open web sharing.

The data in your post is corrupted. It will not decompress.

Try this command:

• convert Gears.tif -density 72 Gears.pdf

Images with bogus attributes such as this one can produce undesirable results. The best solution would be to fix your Gears.tif image so it includes a proper resolution tag.

Hello,
