Yeahhh, except that a lot of code snippet results depend on initial images to begin with ... and as the say goes "an image is worth a thousand words... " I have no intention to address ALL of them - some are indeed lost forever, but some, like ImageShack, promise a restoration of the images upon ...

Fred, It is not just the author of the post - a thread, that one may be interested in, may have dozen of authors, several of those posting may contain files that have been long discarded by the authors. Why not do something that is slightly better - to ask ImageShack to have all specific images of ...

Any updates on the situation of this bug?

Has any effort being made to restore the images deposited along the years with ImageShack for the Forums? I am trying, for example, to read: http://www.imagemagick.org/discourse-server/viewtopic.php?t=11726 but it is literally impossible to follow the discussion without the images. When their policy ...

I imagine you want the verbose on the second command, no? $ convert logo: logo.pdf $ convert -verbose logo.pdf logo.jpg "gs" -q -dQUIET -dSAFER -dBATCH -dNOPAUSE -dNOPROMPT -dMaxBitmap=500000000 -dAlignToPixels=0 -dGridFitTT=2 "-sDEVICE=pngalpha" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-r72x72 ...

I get:

Fred, I have not upgraded IM.

Uoooo! that is interesting ....I am using GS 9.18 which is the latest available from Ubuntu 14.04 LTS. The problem is on 14.04 as well as 14.10 versions of Ubuntu. $ identify -verbose cmyk.pdf | more Image: cmyk.pdf Format: PNG (Portable Network Graphics) Mime type: image/png Class: DirectClass ...

Nope, the image has nothing todo with a PNG, even the generation of it has nothing todo with a PNG. You can try on your own machine! Just download my example and run: $ identify -verbose im-bug.pdf Image: im-bug.pdf Format: PNG (Portable Network Graphics) Mime type: image/png Class: DirectClass ...

I understand, and I see that several things about size, etc ... can be inferred by the PNG produced by GS, but other properties are not - for example - it is wrong to run: identify -verbose file.pdf and get back something like we are getting right now: Format: PNG (Portable Network Graphics) Mime ...

Oh, I see, on "convert" not "identify" . Thank you Fred! Now I see where many other wrong things about the image come from, like for example (on my PDF): Format: PNG (Portable Network Graphics) Mime type: image/png The program is converting it into a PNG and then taking the information from the PNG ...

Add -verbose to your identify command-line to see the Ghostscript command-line we leverage to render PDF. All rendering is performed by Ghostscript. We do some inspection of the PDF and if there were a reliable way to determine colorspace with shallow inspection, we could implement that. It can't ...

Three things here then: 1- We have a problem of labeling, if it is "Color Space as rendered by the GhostScript output device" then it should be labelled as such and not as "Color Space" that has a meaning defined in the PDF Reference Manual and and an usage that is standard in dozens of tools. 2 ...
