For GSoC 2019 I would love to work on the "Sub-pixel and stable glyph positioning" project from the list of ideas without a mentor: https://bugs.documentfoundation.org/show_bug.cgi?id=103322 <https://bugs.documentfoundation.org/show_bug.cgi?id=103322>
I'm particularly interested in this project as I experience poor glyph positioning quite often as a LibreOffice user. To achieve the required skills for this project I read the "State of text rendering" paper by Behdad Esfahbod to further my understanding of text rendering. I've also followed the HarfBuzz tutorial to develop a primitive text rendering program. I've been familiarising myself with the LibreOffice text rendering code particularly CommonSalLayout. I've written a very small patch for this file, changing a variable from tools::Point to basegfx::B2DPoint to add support for floating point values. I've followed the Bugzilla comments and I'm now looking into what changes will need to be made throughout the code-base to store the glyph positions in a floating point variable. Specifically, I'm currently looking into how to make the following code changes: 1. DeviceCoordinate - Change from a long to a double. 2. GlyphItem - Change m_aLinearPos from tools::Point to basegfx::B2DPoint. Change m_nOrigWidth from an int to a double. Change m_nXOffset from an int to a double. I am hoping that somebody would like to be my mentor for this project.
