Hi Dileep,
your proposal looks nice. There's just one important thing missing: Okular
already let's you create FreeText annotations. The confusing thing is that
they're called "inline notes" in Okulars manual, and they're represented as
class TextAnnotation (with m_textType == TextAnnotation::InPlace) in Okular and
Popplers QT5 frontend. Under the hood poppler generates a real FreeText
annotation:
# qt5/src/poppler-annotation.cc
Annot* TextAnnotationPrivate::createNativeAnnot(::Page *destPage, DocumentData
*doc)
{
// ...
PDFRectangle rect = boundaryToPdfRectangle(boundary, flags);
if (textType == TextAnnotation::Linked)
{
pdfAnnot = new AnnotText(destPage->getDoc(), &rect);
}
else
{
GooString * da = toAppearanceString(textFont);
pdfAnnot = new AnnotFreeText(destPage->getDoc(), &rect, da); // Here it
is :-)
delete da;
}
// ...
}
I don't know the original bug you're working on. I assume that what really is
missing is the FreeTextTypeWriter behavior? You can check the ISO 32000 PDF
standard for FreeTextTypeWriter (IT entry of the FreeText object).
@Oliver: Do you know?
You can also fire up okular in gdb and convince yourself
$ gdb okular
(gdb) b AnnotFreeText::AnnotFreeText
(gdb) r
# load document, create inline note => we hit popplers
AnnotFreeText::AnnotFreeText constructor
