Hi, I'm trying to modify one of your sample (..\GdPicture.NET 14\Samples\WinForm\C#\OCR\OCR.sln) to handle multiple pages and process the currently open page from my PDF but currently it only displays one page and when right clicking on the viewer, the navigation menu is disabled as it is only load ...

Hi Cedric,

I ended up with the same problem when using your code and calling the SetROI which was created based on a selection in the viewer. Once I added the top & left points returned from 'GetRectCoordinatesOnDocumentPixel', it sorted the problem.

Thanks again for your help.

Hi Cedric, Thanks for that, but do you know what was actually incorrect in the app I provided you with? The only thing I've managed to spot is the barcode points. They appear to be completely different. I will check the barcode code tomorrow to see if there is anything else but the difference appear...

I printed this document this morning; re-scanned it as a b&w .tiff at 300dpi and now, even though it...

Hi Cedric, Thanks for getting back to me. This is exactly what I was looking for but my annotations are still not being positioned correctly. This is the code I have so far: // get image resolution i.e. 96 float resolution = gdPictureImaging.GetHorizontalResolution(imageId); // get barcode point loc...

Hi, I'm wondering if there was a way to display an annotation accurately (i.e. highlight or other) over a 1D barcode that's been detected on the page. I've seen your demo on how to draw a rectangle on an image (from https://www.gdpicture.com/guides/gdpicture/Overview.html#GdPicture.NET.12~GdPicture1...
