How exactly are layers / optional content groups meant to work?

Hi, GdPicture v12 has added support for PDF layers AKA optional content groups but I can't really get it to work. My first try was using the sample code from https://guides.gdpicture.com/content/GdPicture.NET.14~GdPicture14.GdPicturePDF~NewOCG.html My expectation is a PDF file containing an addition...

Re: Save annotations without recoding image?

The meta data is just some XML at the beginning of the file. Why would you not be able to only modify the XML without touching the image data?

Re: Save annotations without recoding image?

How do you suggest to save annotations to a JPEG image then? You can hardly expect me to save them in a separate file, because your SDK advertises the ability to save annotations to images. It is not acceptable that the image quality deteriorates everytime an annotation is modified.

Re: OnCustomAnnotationPaint in WPF.GdViewer

I'd also need it, without this feature the WPF control is useless for me.

Save annotations without recoding image?

Hi,

is it possible to save annotations made with the GdViewer control to an existing image (as meta data) without re-encoding the image to avoid quality loss for JEPG files?

Best regards,
Florian

Re: OverflowException in PdfSearchText

.Width = 0
.DisplayFromFile(...)
.PdfSearchText("something", 0, false)

Does that not work for you?

OverflowException in PdfSearchText

Hi,

when you call the PdfSearchText() method and the PDF viewer currently has a width of 0, the result is an OverflowException. Could you possibly fix that?

Best regards,

Re: PdfSearchText results sometimes weird

OK, I submitted a support case. What I just remembered is that the PDF is not actually OCR'd, but it was searchable from the start.

When using PdfSearchText, I get the following results: ?pdfViewer.PdfSearchText("60, 3", 0, false) false ?pdfViewer.PdfSearchText("60, 36", 0, false) true Why is a more specific match found, but the generic one is not? Is it possible...
