- Pass in the initial matrix to the annotation provider, so that it can return
the correct rectangles / quad points.
- Made a change / extensions to the Annotation class:
- ModifiedDate is now a DateTimeOffset instead of unparsed string.
If the string is invalid, ModifiedDate is set to the default value.
- Added lookup for the "appearance streams"; all the annotations should have
a "N" (normal) appearance, and optionally have a "R" (roll-over/hover)
and "D" (down/click) appearance. Did not expose the actual stream objects,
but added a flag indicating the existence of "R" / "D". At some point
we can consider doing something with the appearances.
- Changed signature of GetInitialMatrix / ContentStreamProcessor constructor
from PdfRectangle back to what it was earlier, namely MediaBox and CropBox,
to prevent accidentally mixing the two up in the caller.
an arrray of 4 items representing a rectangle may define its values as indirect references. when converting to a rectangle we pass a pdf token scanner to resolve any indirect references.
highlight, link, strikeout, squiggly and underline annotation types may define a set of quadrilaterals using the quadpoints entry. this defines the regions to show/activate the annotation. the order of points in the quadpoints array does not match the specification so we provide a convenience class to access the point data rather than interpreting it as a rectangle: https://stackoverflow.com/questions/9855814/pdf-spec-vs-acrobat-creation-quadpoints.
the 3 font types mentioned are moved to the new fonts project, any referenced types are moved to the core project. most truetype classes are made public #8.
