Hello All, Has anyone had any experience of photo capture in an LCL app on Windows? I am working on a field data recording program for a tablet PC with an embedded camera. I would like to be able to capture a high res. photograph with this and so far I have tried VFW, TWAIN, WIA and DirectShow with the following results:
VFW This worked well, but the resolution seems to be fixed at WebCam type levels and access to the frame-buffer is non-trivial. TWAIN This works, but it is slow and always throws up the default dialog box and I can't find a way to switch this off. WIA This works but is unusably slow! From pressing the camera button to generating the memory bitmap takes over 10 seconds. DirectShow I have seen some good Delphi samples that produce high res. images with sub- second response times, but I can't get them to work with FPC. Any hints or suggestions would be greatly appreciated. Thanks, Paul Michell -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
