Dear all,<br><br>I'v been lacking a good tool for studying* and since I
have some knowledge of programming, albeit basic, I've started a project
to create this tool, surrounding a PDF viewer.<br><br>Working with PyQt4 and python-poppler-qt4
I've managed so far to display PDFs in a scroll area and make some text
selection. However, the zooming and scrolling on the document is very
poorly rendered. Scrolling is delayed while the image is loaded onto
visible pages and zooming (i.e. resizing the document) renders all
rickety and flickery.<br>
<br>Would you have any suggestions on how to proceed? <br><br>Thanks.<br><br>Benjamin<br><font size="1"><br>
