Hi!

I'm trying to render a PDF document to PNGs. When the PDF has any kind of highlight annotation, the text behind it is jagged and aliased. Is there anything I can do to correct this?

Thanks!

Rashid,

Thanks - I am actually working with code identical to that in the first example, but when there are highlights in the PDF, they end up looking jagged and aliased.

I've attached a section of the PNG that it renders, and here is a link to the original file:

https://www.adobe.com/support/products/pdfs/adobe_products_and_windows_vista.pdf

The highlights were made in Acrobat.

Hi Geoff,

Thanks for your request, highlighted text in the PDF Document will not be jagged after conversion to PNG by using the below code.

Document pdfDocument = new Document("adobe.pdf");

using (FileStream imageStream = new FileStream("image.png", FileMode.Create))
{
   //create PNG device with specified attributes

   //Width, Height, Resolution, Quality

   //Quality [0-100], 100 is Maximum

   //create Resolution object

   Resolution resolution = new Resolution(700);

   PngDevice pngDevice = new PngDevice(resolution);

   //convert a particular page and save the image to stream

   pngDevice.Process(pdfDocument.Pages[1], imageStream);

   //close stream

   imageStream.Close();
}

Please do let us know if you need any further assistance.

Thanks & Regards,
