    Batch modify images inside a PDF

    I know that the PDF format is a "final format" so it should be modified the less the best
    BUT
    I would l like to batch resize/sharpen and eventually colormodify all the images inside a PDF
    so if anyone knows a pluggin/script/software that could do that it would be great

    thanks

    Before posting here I have search myself a lot
    but maybe someone had better luck than us!
    Maybe with the Adobe SDK it would be possible to write such thing in C but I have no time to do that !!
    So maybe it would give an idea to someone !

    Change the color of images can be done with a colorserver such as Alwan CMYK Optimizer. this software can also use a sharpen filter like Adobe Photoshop for all images contain in PDF.

    To Downsample PDFs, you can use PitStop Server. This software can also do the color management, but don't expect best results.

    Forget the idea to write a piece of software for that... it's extremely complex. (not to create a batch... but handle PDF specification and color management)

    Hope this help.

    Re: Batch modify images inside a PDF

    If there are not many photos, you can manualy cut them from the PDF with Pitstop. Paste them into photoshop and work on them there. Pitstop also has the ability to remap colors etc. But I'm not sure if it can do all that you require. In any case I would suggest reading in-depth about pitstop's image handling capabilities.

    PitStop is a good option

    .
    is the pitstop downsampling better than the acrobat one . is there a way to put some sharpening this way ?

    I was thinking about a "script/ptogramm" that would use the modify object in photoshop ability from acrobat and then run a photoshop script. look complicicated ( the acrobat scripting part ) but not impossible

    As far as I know, no. downsampling methods are kind of straightforward... I don't think you can expect get some sharpening via this way.

    IMHO, it's not the good direction...
    First, open images in Photoshop via Acrobat can work some times, but not everytime and for sure. Depending on the size and compression method, images can be divided in many smaller parts... therefore, you should open and edit all of them and keep in mind you can have different objets over the images that make the task harder.

    Also, it's important to keep in mind that unsharp mask doesn't work well for all images... so becareful.

    Alwan's sharpen is the same method as Photoshop... so if you have the software, I would go this way which is the simplest + Pitstop server to downsample all images...

    Touch up in Acrobat will open picture in Photoshop and you can make modifies. After the changes you save it and close the file. All corrections would be reloaded to pdf in Acrobat.

    Alwan CMYK Optimizer is really worth looking at. Aside from correcting the images, it handles complex files with transparency, etc. Very well. The GCR algorithms are probably the best available. Make ready is faster on press, and there is a significant ink savings on both conventional and digital presses.

    My favorite is ReaConverter photo editing software. I have just used it by download from that [URL="http://www.reaconverter.com/"]link[/URL] it contains anything a digital camera owner might need to correct or enhance their photos

    PDF should not have this feature, do not know there is no such a plug-in, if you really want to bulk repair celebrate or with the original document would have been better to modify.
