The code basically boils down to: // create poppler pdf document

This reflects an additional dependency on cairo, so I went ahead and converted the cairo based code to Qt, using libpopper-qt4. So I looked into the source code of pdf2svg and saw that it uses libpoppler with Cairo. The result was perfect: InkScape renders the svg file exactly like Okular renders the pdf file: So I first tested to convert the pdf to svg with this tool and then view it in InkScape. In theory, I then can use QSvgRenderer to load and render the SVG on-the-fly using QSvgRenderer::render(QPainter*, …). Next, I found pdf2svg that converts a pdf file into the scalable vector graphics format svg.

This works, but whenever you scale the canvas the result looks ugly since png is not a vector graphic. So I could convert the dvi file to png through QProcess+dvipng, and then display the png file. It even supports transparent backgrounds. So I searched the net and found dvipng, which converts a dvi file to png. This works in principal, but there is a licensing problem: libpoppler is GPL, and I want to use it in a LGPL library. So I thought it would be nice and accurate to compile the TeX code to produce a pdf, and then use libpoppler-qt4 to draw the pdf. It should be fine.In a project I’m currently working on I need to display the result of TeX code. You shouldn't have wide tracking on u/lc text unless you are very very good at getting it perfect.Īll that said, if your printer isn't a total buffoon, he can fix problem 1 in about three seconds. For instance, look at the space between the m and the e in 'Argument' versus the u and m. Adamrice is right, your kerning is not very good. Judging by eye I'd say you want your text to be 0/0/0/100 (or if your printer actually specifies a rich black, then those values) and your ornaments to be 0/0/0/40.Ģ. A lot of large-format printers (sign folks, mainly) are dumb as rocks and have horrible workflows and just throw customer files at their grand-format digital inkjet printers without even checking to see if there's going to be a problem. Change them to CMYK or you're going to be unhappy with the results unless your printer is smart enough to preflight your document first. Both the ornaments and the text are RGB, not CMYK.
