How to display 2nd page of TIFF

[mchernecki]

I am developing an app to review scanned TIFF images, each file is 2 pages (front & back). I have 2 GDViewer panels next to each other displaying the front and back page. How can I automatically display the 2nd page in the back-page GDViewer panel. I am currently using the following code to do this, but I get the first page display then change to the second ... very annoying. I would like to display page 1 in GDViewer1 and page 2 in GDViewer2. How can I do this?

ImageSrc1 = oGdPictureImaging.CreateGdPictureImageFromFile(fi.FullName);
ImageSrc2 = oGdPictureImaging.CreateGdPictureImageFromFile(fi.FullName);
if (System.Convert.ToDouble(oGdPictureImaging.GetStat()) == 0)
{
gdViewer1.ZoomMode = ViewerZoomMode.ZoomModeHeightViewer;
gdViewer1.DisplayFromGdPictureImage(ImageSrc1);

gdViewer2.ZoomMode = ViewerZoomMode.ZoomModeHeightViewer;
gdViewer2.DisplayFromGdPictureImage(ImageSrc2);
gdViewer2.DisplayNextPage();
}

Thanks

Hi,

You can try this:

Code: Select all

ImageSrc1 = oGdPictureImaging.CreateGdPictureImageFromFile(fi.FullName);
ImageSrc2 = oGdPictureImaging.CreateGdPictureImageFromFile(fi.FullName);
if (System.Convert.ToDouble(oGdPictureImaging.GetStat()) == 0)
{
gdViewer1.ZoomMode = ViewerZoomMode.ZoomModeHeightViewer;
gdViewer1.DisplayFromGdPictureImage(ImageSrc1);

gdViewer2.ZoomMode = ViewerZoomMode.ZoomModeHeightViewer;
gdViewer2.LockViewer = true;
gdViewer2.DisplayFromGdPictureImage(ImageSrc2);
gdViewer2.LockViewer = false;
gdViewer2.DisplayNextPage();
}
