The size of PDF files produced by LO-PDF export can be the double of this produced using postscript rendering. By postscript rendering images use only the CROPED size off the images, the LO- Cairo-rendering uses the FULL image to store in the PDF file. I do not know if Cairo lets the choice between Cropped and Full size rendering ? For editing PDF , full size is handy, but a option with the choise between the two would be super handy. Reducing Size for PDF (on the web) is still important !
That's a nice localized change that would be suitable as an EasyHack: one would need to review all methods rendering bitmaps in vcl/source/gdi/pdfwriter_impl.cxx (e.g. PDFWriterImpl::drawJPGBitmap() etc), inspect the current graphic state (see PDFWriterImpl::updateGraphicsState() for what's going on there regarding clip), and then prune the bitmaps written to pdf down to what's not clipped away.
The chooise between cropped and non-cropped would be ideal
This enhancement would be really useful. I support it via Freedomsponsors: http://www.freedomsponsors.org/core/issue/246/add-option-to-crop-images-in-pdf-export
I am beginning work on this issue.
adding LibreOffice developer list as CC to unresolved EasyHacks for better visibility. see e.g. http://nabble.documentfoundation.org/minutes-of-ESC-call-td4076214.html for details

>> Dag Cor welkom hier In the mean time i have writen this option in Basic who is a bit slow because i replace al cropped images by new images (with the cropped size an the propper resolution). For better quality i can use ImageMagic or when quality is less important, the LO graphicfilter who produce sometimes less quality conversions. If someone is interested i can post the code here

I plan to work on this, but I'd like some clarifications first. Is cropping the only desired feature, or is automatic resizing/resampling of non-cropped images wanted well? I can grasp the PDFWrite without much difficulty, but I don't know how would be the best way to provide UI toggles, or where their corresponding code should be. Any assistance would be appreciated.
Daniel, Thanks for the interest to improve LO to make better (more professional) PDF. IN LO we ca do everyting needend to produce high quality documents, books, magazines etc. The link to Professional printers is still PDF. Here we are talking about the storing of images in the resulting PDF. 2 options: Full Image who permit to re-edit this image in the PDF. Cropped Size off the Image who delivers smaller PDF Resampling is a separeted thing and can now allready been done when using the API and macro to produce the PDF (filter options). But The Resampling is not present in the current GUI and can been ussefull as well. I Suppose there can been more done to make smaller, leaner PDF also Storing, a PDFdocument as a Image (not a OLE object) in LO documents would also been a greath improvement ! Greetz Fernand
@Daniel: You could start by adding support for cropping. I would turn it on by default and add an option to toggle it off under the "Image" options in the pdf export dialog. Please ask if you need code pointers - you can also join IRC and ask there!
