            Description

            I have a very simple pdf file as attached. I can see the text "squre, circle, .." in each block with other PDF reader(foxit), but I cannot see them if I open the file with ICE PDF viewer.

            to reproduce it just compare the result with different pdf reader.

            anyway to upload the attachement pdf file?

              I see the problem using the OS version of the ICEpdf. The PRO version renders the document fine.

              We'll need to take a closer look to see why the shape text isn't being displayed by the OS version.

              look likes it is a font size problem. the point size pass to the OFont.derideFont() is 0.33333, which will reset the size of the font to 0.

              I tried a simple fix to this issue. it works, but I am not sure whether it impacts the existing logic.

              the basic idea is use a float field to track the scale between the font point size the PDF wants and the real font's point size. and do the scale when calulting the asent/desent/bounds and render the text.

              I can help if anybody need the fix.

              Would it be possible to provide a path for evaluation?
