Q: Can PDFNet SDK recognize OPI commented images?
---
A:
Using PDFTron PDFNet SDK you can access any information in PDF
document.
For example, to access alternate image(s) (see 'Alternate Images'
section in chapter 4.8.4 in PDF Reference Manual) you can use the
following C# code snippet:
Obj img_dict = image.GetSDFObj();
DictIterator itr = img_dict.Find("Alternates");
if (itr != img_dict.DictEnd())
{
Obj alternates = itr.Value();
if (alternates->IsDict())
{
Image alt_img = new Image(alternates);
// ...
}
else // Array of Alternates
{
for (int i=0; i<alternates.Size(); ++i) {
Image alt_img = new Image(alternates.Get(i));
// ...
}
}
}
