PDF of Tablet Notes Renders Incorrectly
The following pdf of some notes/drawings on a tablet renders partially although incorrectly. Also is not a simple pdf so it might be something to tackle further down the development cycle.

Not showing much of my PDF
Hi, I'm not sure about PEP. I have an editable PDF that hardly shows in PEP
Lots of blank and lines.
Is it supposed to work?
thanks
Does not open file
Hey there,
first of all: UI looks great. I like it and I hope PEP gehts more and more sophisticated over time.
Despite your notice to open "simple" PDFs I went full force with a term paper I created with LaTeX which it does not seem to even open.
Maybe you wann a take a look at that. Maybe it's just something simple. Who knows.

I have been working on the text rendering and editing since the very begging of PEP, now I have almost done with the text part, but still need to improve it, I think this is a long term issue. Anyway, let's take a looking some cool screenshots.

Save "Layout-aware text extraction from full-text PDF.pdf" gets mess text result
Edit some text in Layout-aware text extraction from full-text PDF.pdf and save it as PDF, the saved PDF has mess text, which means the saving is buggy.

Application stuck when trying to open a pdf book
I was trying to open a pdf version of a book but the app got stuck and the wheel spinning. Had to force quit.
I cannot share the file, since it's under copyright, but only some details about it, I'm sorry.
PEP: 0.27 alpha
File size: 1.414.753 byte (1,4 MB)

Some part of text positions are wrong after saving PDF for last page.
3D_Silhouette_Rendering_Algorithms_using_Vectorisa.pdf
GTexParser can not make correct lines for iasj.pdf
Since the distance of some glyphs are large, so that GTextParser thinks they can not be combined into a word, so the text block are not correct which cause the bug.
The pdf: iasj.pdf
Some texts in Number_Theroy.pdf do not response to mouse hover
Some text in page 3 shown in the screenshot with red circle do not response to mouse hover in this PDF Number_Theory.pdf
Text rendering issue again
There are some text rendering issue on some page of 3D_Silhouette_Rendering_Algorithms_using_Vectorisa.pdf
Maybe a bug in the future PDFs?
The text parser in every page, begins by using sorting all TJ text to make read order glyphs which is faster than using every single glyphs.
I am thinking about this case, where a TJ text at the end of the page content, resides in the middle of another TJ text, how will the current algorithm in PEP handle this? I am not 100% sure. Let's see and leave this issue here as a memo.
Font encoding not implemented for "Identity-H" encoding
Page 5 of the PDF 3D_Silhouette_Rendering_Algorithms_using_Vectorisa.pdf has some missing glyph, because the font dictionary is as follow:
102 0 obj
<<
/Type /Font
/Subtype /Type0
/BaseFont /GPMEBE+SymbolMT
/Encoding /Identity-H
/DescendantFonts [722 0 R]
/ToUnicode 723 0 R
>>
We did not implement Identity-H encoding, so this is the reason.

Scanned PDF Fails With Blank Pages
Opening the attached pdf renders blank pages with nothing on them. Looks like it renders the correct number of pages though which is a start! I realize this PDF might not be super simple since it seems it is a scan but good to log in the issues for later in the development cycle at least.

PEP does not render a musical score PDF
Text editor some glyph position not correct for coders_at_work.pdf
Before adding a:
After adding a:
The space before 'd' shifted.
Due to the copyright of the PDF, I can not upload it here, but it's in the page 4 of Coders At Work.pdf, hence the name.
Text rendering missing for page 4 of raft.pdf
Lack of implementation of XObject for PDF page
Due to no implementation of XObjects, some pages of asiabsdcon2009-sensors-slides.pdf are not rendered correctly.
Would be better to use text matrix of glyph to identify two glyphs's y position delta
Since two glyphs in the same line may sometimes have their own frames, which are not the same height, so it's better to use
text matrix to identify if they are in the same line while make lines.
Let's take Number_Theory.pdf for example. Number_Theory.pdf
Text extraction algorithm is buggy for raft.pdf
Since there are almost no space found in raft.pdf, the text extraction algorithm in PEP can not correctly handle this case.
I am working on a fix for this.

Text parser does not correctly make text blocks
The text parser dose not make text blocks correctly, for raft.pdf. Due to the two columns text layout in this pdf. It only make one line as one text block.
Crash for type3 fonts in PDF
PEP crashed while there is any Type3 fonts in PDF, for example, Elementary_number_theory_book.pdf
Since we Type3 fonts do not have any embedded font program in PDF, so crashes.
didn't display the text properly
hey, so I oppened a pdf and this happened
Interesting display contrast issue for PEP
Increasing contrast
Contrast 1
Contrast 2
We got different results. Which cause the page boundary to be almost the same as white background.
