Per this thread http://forums.adobe.com/message/1162092#1162092 You need to use PDPageGetCropBox() to get the user space coordinates of the page, and then you have to convert it to device space coordinates (or something). I'm not exactly sure what the conversion method or calculation is, however. Here's a snippet of my code, and the rectangle values appear to be insane, at first glance. ASFixedRect rect; PDPage pg = PDDocAcquirePage(pdDoc, 0); PDPageGetCropBox(pg, &rect); char str2[512]; sprintf(str2, "Right = %i - Left = %i -- Top = %i - Bottom = %i\n", rect.right, rect.left, rect.top, rect.bottom); AVAlertNote(str2); PDPageRelease(pg); For some standard 8.5x11 inch docs, I'm getting a right value of 40108032 and top value of 51904512. Divide right by 8.5, and top by 11 and you get 4718592. 65536 * 72 = 4718592. For all of the documents I've tested this on (dividing page width/height by user units for height/width), I'm getting this same value. Do these rectangle values I'm getting back look normal? Why is 65536 in there? Does it have something to do with the number of colors (256^2)? In my program, I will be iterating through all the pdf's in a directory, and I need to check the page size before attempting OCR, in order to prevent that alert box from popping up warning about the 45x45 inch page size. I don't fully understand how user space coordinates relate to actual page size in inches, and would like to know if I can simply reliably divide my user space coordinates for each page in each document by 4718592 in order to get the actual page size in inches.

Create a PDWordFinder. For each page in the document, call PDWordFinderAcquireWordList. The last parameter in that function is the number of words in the page. ... View more

I have a couple of other questions. I am writing a C++ plugin to perform OCR on all pdf files in a directory. 1) Currently I can run OCR/Paper Capture on all pdf files in a directory, and further, I can detect whether the document is already searchable to try to cut down on some processing and avoid the problems seen in question #2. The problem is that although OCR has been run on one or more pages in a document, there are still occasionally pages in a document that have not been OCR'd. I know how to loop through each page and check if there are any words on the page, but I'm not sure I can run AVCommandExecute on an individual page instead of the whole document. The documentation AVCommandExecute indicates that you can use AVCommandSetParams() to configure the command, and that this function allows you to select the pages to act on. "AVCommandStatus AVCommandSetParams(AVCommand cmd, ASCab params) Sets the parameters for the specified command. The parameters are  those pieces of information that can be controlled by the user, such as  the pages to act on. Use this method and AVCommandSetInputs() to set up  a command before calling AVCommandExecute() to execute it." However, after doing some scouring of the API reference and googling, I'm not sure how to do this and was wondering if someone could push me in the right direction or give me a sample. What do you name the key, what type of value to put in, how does the command know what to do with it? 2) On some, but not all, already searchable pdf's, If I try to OCR them an alert box will pop up saying there is already renderable text on the page and the plugin won't continue running until the alert box has been closed. I think this may be popping up when the document used clearscan. I have set the UIPolicy to silent already but it doesn't seem to affect that. Is it a matter of catching an exception or is there no way around this? Here's how I have configured the command:     ASCab config = ASCabNew();     ASCabPutInt(config, "UIPolicy", kAVCommandUISilent);     AVCommandSetConfig(cmd, config); What's the solution? Thanks. ...

I downloaded the vmware appliance as linked to on this page: http://www.adobe.com/devnet/livecycle/trial.html Inside the virtual machine, I opened my browser and logged into to the administration console @ localhost:8080/adminui and went to: Services > Live Cycle PDF Generator ES2 > File Type Settings > New File Type Setting Under image to pdf, there is no option to use OCR, as there are when the software is installed onto a windows machine. Per this thread, the OCR feature is not supported in Linux: http://forums.adobe.com/thread/791202 This is a problem because the machine that would be running this is a linux box. So I'm back to using the PaperCapture command. It appears no documentation on how to set parameters (to avoid the dialog asking for the OCR settings) is available. Is there any way to request this info? If there is documentation on this, can you direct me to it? I have done a lot of searching around but have come up with nothing. Thanks. ... View more

Thanks, I'll start looking in there and I'm sure I'll be back with questions. ... View more

I too need to know how to set parameters for the PaperCapture command programmatically. I can't seem to find it in the documentation anywhere. Our problem is we have about 75k pdf's to OCR. I know we can do this with batch processing via the GUI, but we would like to do this programmatically so we can see a log of errors if the process fails. Is there any reference for the PaperCapture command, so that we can specify our preferred settings before we execute the command? Thanks. ... View more
