When I extract signature images from a pdf, the resulting images are in black and white. For example, if the image is blue with transparent background, the result would be a white image with a black background. Same for black signatures where the background becomes black and the signature becomes white. Note that the original signatures are in Png format.
This is the code that I’m using to extract the signatures:
int count = 0;
using (Document pdfDocument = new Document(pdfPath))
