pdPageExtractText() crash on file created using LaTex #44

Closed gwierzchowski closed 5 years ago

pdPageExtractText() raise following error when used on file created by Latex:

"/home/grzegorz-neo/Dokumenty/Projekty/MatFiz/pdfio-test/outline.pdf"
(v1.0) julia> doc = pdDocOpen(filename);
(v1.0) julia> item_pg = pdDocGetPage(doc, 3);
(v1.0) julia> buf = IOBuffer();
(v1.0) julia> pdPageExtractText(buf, item_pg)

Change: d[i+1] = widths[ix] into d[i+1] = round(Int,widths[ix]) in PDFontMetrics.jl fix this issue. Fix is included into PR with implementation for Outlines.

Pls. check-in fix for this separately from pdDocGetOutline(). It's best each individual check-in kept granular.
