2023 GSOC Application

[peter frane]

To whom it may concern,

I'm interested in contributing to your projects through the 2023 GSOC.

My name is Peter Frane (IRC nick PeterF). I'm an editor by profession and a
freelance programmer.

The projects I'm interested in are under the 'Ideas without a mentor':
https://wiki.documentfoundation.org/Development/GSoC/Ideas_without_a_mentor

Specifically, these ones:

*Subpixel and stable glyph positioning tdf#103322*

I had previously written an open-source library (
https://reformath.webnode.page/) that uses subpixel glyph positioning. This
library is available under both Windows (GDI) and Linux. I had already
browsed the Writer source codes involved, but still have some questions. I
am going to apply my deep knowledge of Windows GDI and fonts to fix this
issue.

*Support multicoloured font formats tdf#104403 tdf#105488*
I have in-depth knowledge of the OpenType font format. I have written an
OpenType to Woff converter and vice versa. Both are available at my GitHub
page. I am also very familiar with SVG. I am very familiar with fonts and
graphics rendering, although, admittedly, I have not used the SVG feature
of OpenType.

*Implement Quattro Pro Import filter*
Although I have not used Quattro Pro in years, I'm interested in this
project because I like tinkering with file formats. Some formats that I
know include Corel's WordPerfect (I used to have the documentation because
I tried to convert it to XML back in the day), MS RTF, Adobe PDF and
PostScript (I have written a library for both: a PDF writer and a
PostScript interpreter), TeX/LateX DVI/VF/TFM (I have written a program
that converts a DVI file to SVG and PDF), graphics (BMP, EMF/WMF, PBM, PPM,
SVG, PS/EPS), fonts (Type1 and OpenType; I have written a Type1 font
subsetter and a WOFF converter for OpenType). Most of my programs are open
source and available at my GitHub page.

*Implement MathType 4+ import filter*
I am familiar with and have studied the old MathType file format, but not
the new one. The old one is an OLE object that wraps a WMF file that, in
turn, contains some EPS code. As mentioned above, I know WMF and EPS, so
all I need to do is study this new MathType format, which, I believe, is
properly documented by Design Science (now Wiris).

*My proposed project: EPS reader/interpreter*
If you still need an EPS interpreter, even if it just supports a subset of
the language, I have made available the source code of my interpreter on my
GitHub page. I am willing to integrate it into LibreOffice if you will
accept me to work for you.

I would like to discuss all of these in an interview.

Thank you and I look forward to hearing from you.

Regards,

Peter Frane, Jr.
