I've experimented with filtering some content in streams. I've tried with both Get/SetPageContentFromString and Get/SetContentStreamFromString. I get the content OK, but even if I don't change it, just set it back, the page gets mangled. It looks like the page shrunk and is rendered in something like a 50th size. Just a mess of black "lines" in the lower left corner, about 1 by 2 centimeters.

An experimental method to draw on a newly created page:

int nCS = QP.NewContentStream();
QP.SelectContentStream(nCS);
QP.SetContentStreamFromString(sRawPDF);

Render();

with sRawPDF being

268.8066 424.4088 m
271.8255 420.2306 l
S

which is a snippet i found here.


It's supposed to draw a line, and it does. But just something like half a centimeter long in the lower right corner.

I've experimented with SetScale, SetMeasurementUnits and such, but with any changes to the output.

I'm using a quite old version (16.11), but I hope (don't think) that shouldn't matter.

Anyone, any ideas?
