The 75 came from observing that the "duration" of a player with a PDF loaded seemed to be 75*(z-1) where z = the number of pages. Nice observation, I wouldn't have thought of it. The next question is if that's a Mac-only convention or if it works universally. If it's universal, it becomes a handy cross platform solution. -- Jacqueline Landman Gay | jac...@hyperactivesw.com HyperActive Software | http://www.hyperactivesw.com ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

Thomas McGrath III: Do you have more code or explanations about how this works? I am actually looking for a step for images in a scrolling group on iOS and Android but your email made me think that maybe a pdf might work. I need the images to 'land' fully in view even if the user has not scrolled all the way on a touch. I don't know about iOS or Android, but I would think you could move an image to the group's top edge by setting the scroll of the group to the top of the image minus item 2 of the formattedRect of the group.

Re: Page 2 of a PDF
I've been using "pdfimages" one of the tools that comes with "xpdf"; I am using Livecode shell calls to batch process a hundred or so pdfs of old letters which were scanned as pdf. From the commandline, pdfimages outputs numbered jpg or ppm files of each page in multipage pdfs. (Note: this only works with images inside pdf files, not actual pdf text; xpdf has a tool "pdftoppm" which outputs raw images of multipage pdfs; but I haven't tried it.) xpdf webpage: http://www.foolabs.com/xpdf/index.html Mac On Apr 4, 2013, at 2:35 PM, Ray Horsley wrote: > I believe this has come up before but don't I see any way to convert page 2, > page 3, etc. of a PDF to a PNG or JPEG via snapshot using either revBrowser > or a player object.

Re: Page 2 of a PDF
I was calling imagemagick and ghost script for a while to do this from the shell, but recently start using VeryPDF's proprietary solution for doing this from a command line to save on filesize when I bundle it.

Page 2 of a PDF
I believe this has come up before but don't I see any way to convert page 2, page 3, etc. of a PDF to a PNG or JPEG via snapshot using either revBrowser or a player object. A browser object doesn't seem to display a specified page at all, and while I can manually scroll through a PDF using a player object I can't control from a script which page of the PDF the player object is displaying. The end result is to convert a single PDF to multiple PNG's or JPEG's. Suggestions?
