genprint Print Processor
in [Device Drivers]
|
From: jrc.src on 23 Aug 2006 02:52 HI all, I am new to print processor, from genprint source from DDK, i am trying to get EMF data from PrintDocumentOnPrintProcessor() using pData and pDocumentname parameter,? In PrintEmf(), i get handle to spool file. and i m using that. ? Please point me to correct direction. What i want to do is to get EMF data and then convert it to bmp file to be stored in specific loacation. My understanding is "The Windows Default EMF processor renders the image to the printers DC. If we simply reset it to render onto our own DC, we get our bitmap" Thanks in Advance.
From: Christoph Lindemann on 23 Aug 2006 04:37 If you want to print to a "bitmap file", I strongly suggest that you implement this with a printer driver! If you realy must get the EMF data, you can get help on the following pages. But mind you, that this is not officially supported, and your applications could break in the future. Also note that the print system changes with Windows Vista. http://undocprint.printassociates.com/winspool/spool_files In the print processor you can not use the parameters to access the actual spool file, instead use OpenPrinter to read from it http://undocprint.printassociates.com/winspool/spool_files#reading_job_data -- Christoph Lindemann Undocumented Printing http://undocprint.printassociates.com/ <jrc.src(a)gmail.com> wrote in message news:1156315921.482541.209430(a)h48g2000cwc.googlegroups.com... > HI all, > > I am new to print processor, > > from genprint source from DDK, i am trying to get EMF data from > PrintDocumentOnPrintProcessor() using pData and pDocumentname > parameter,? > In PrintEmf(), i get handle to spool file. and i m using that. ?

Please eloborate little more. > If you realy must get the EMF data, you can get help on the following pages. > But mind you, that this is not officially supported, and your applications > could break in the future.

I think you can extract the EMF from the SPL file . it is easy to do. jrc.src(a)gmail.com wrote: > HI all, > > I am new to print processor, > > from genprint source from DDK, i am trying to get EMF data from > PrintDocumentOnPrintProcessor() using pData and pDocumentname > parameter,? > In PrintEmf(), i get handle to spool file. and i m using that. ?
