Current status

[alexandremottet]

Hi,

I would like to know what is the current status of those project and in particular the "unix-toolbox.js-imagemagick" ? Is it active and working ?

Regards

[manuels]

Yes, imagemagick is working fine. Checkout the ./demo folder to see how to use it

[alexandremottet]

Ok, I've already tried it and several errors comes out :

Does it came from my computer (chrome) ?

[manuels]

I found the bug: I didn't update the submodule to the latest version. You can try again, it should work now.

[alexandremottet]

Ok, thanks for reply so quickly !

Works for jpg/png but I was unable to convert a G4 tif file image with unix-toolbox. The same image goes ok in command line (convert "g4.tif" "g4.jpg").

The test file : http://www.fileformat.info/format/tiff/sample/ff5798fb1a324c099af642690d161877/download

When you compile ImageMagick, did you add some exclusion ?

[manuels]

Yes, I did not include all image format libraries. However, I included tiff. So it's strange that this does not work. What's the mime type of your tif file? is G4 tif different than the regular tif format?

[manuels]

Oh, G4 tif means group 4 tiff (Raw CCITT Group4) according to identify -list format.

Probably I did not include this format library...

[alexandremottet]

Ok. The mime-type is "image/tiff" given "file --mime-type g4.tif" command line. This is a regular type for register tiff file (fax).

[manuels]

Can you run convert -identify g4.tif (on your computer and in the browser) and post the output?

[alexandremottet]

It give me this line : g4.tif TIFF 2464x3248 2464x3248+0+0 1-bit Bilevel Gray 57.3KB 0.050u 0:00.049

[manuels]

^^Is that the output for both or did you just try it in the console?

[manuels]

Can you publish this image anywhere so I can try it myself?

[alexandremottet]

I used this image example : http://www.fileformat.info/format/tiff/sample/ff5798fb1a324c099af642690d161877/download

Now, i'll just try in the console.

[manuels]

I'm not sure if the file is valid. Even my native imagemagick (debian 6.7.7-10 2013-09-01 Q16) tells me convert.im6: no images defined 'g4.tif' @ error/convert.c/ConvertImageCommand/3044.

[alexandremottet]

I think this image is valid (from file format.info). This command line (convert -identify "g4.tif" "g4.jpg") work on my computer (mac osx).

What is yout ImageMagick version ?

[manuels]

It's 6.7.7-10 2013-09-01 Q16 and yours?

[alexandremottet]

It's 6.8.0-7 2013-09-19. I don't know if there is so much difference between those version.

[manuels]

Got it: I did not use the additional 'g4.jpg' parameter. So it also works with my native version. But I did not figure out which delegate is responsible for GROUP4 images.

[alexandremottet]

The js version of "convert -identify .." gives : Magick: no decode delegate for this image format `/g4.tif' @ error/constitute.c/ReadImage/550.

[manuels]

I think I got it: probably CCITT support is not included in libtiff. Right now I don't have my laptop (I lost the power supply and I'm waiting for the new one). As soon as I can use my laptop again, I can check whether this really is the issue and fix it.

[manuels]

Hmm, I don't get it! Line 8 in tif_config.h clearly states that CCITT Group 3 and 4 support should be included!
