Expert input required for pixel aligned rendering of fonts.
Hi, I am reaching out to the text font rendering community seeking guidance and expert inputs on an issue which we are facing while rendering text using OpenGL. This is not specific to any freetype usage per se. How do we need to ensure that the start 2d position of a text always falls at the pixel boundary ? I use OpenGL to render the text! Thanks, Bala.

Halo Glyphs generation query
Hi, Can someone please help or provide any guidance on how to get halo effect around each glyph generated by Freetype . We use 2.9.1 Freetype version. I see an example from the below Freetype website. Is this is the best way or are there any other simple, effective ways to generate halos ? Please guide. https://github.com/genesi/freetype/blob/master/freetype/docs/tutorial/example2.cpp Thanks, Bala.
RE: [External] Re: Query on Generation of halo around glyphs.
Thankyou for the reference. I am looking for something where I can generate the halo at run time and not at the design time(offline). -Original Message- From: Freetype On Behalf Of Lawrence D'Oliveiro Sent: Thursday, June 23, 2022 9:33 AM To: freetype@nongnu.org Subject: [External] Re: Query on Generation of halo around glyphs.

Query on Generation of halo around glyphs.
Hi, Using freetype APIs, any recommendation on how to generate halo, of a given width, around each glyph, using Freetype APIs ? As of now, I see this https://www.freetype.org/freetype2/docs/tutorial/example2.cpp. Any other options ? Thankyou for any help! Thanks, Bala.
RE: [External] Re: Kerning information related query.
Thankyou for your response. For some reason, the link provided below is not opening for me. Could you please send me the source file(s)? present in the Github which I can refer to understand the kerning usage ? My use case is: Using freetype API, get the kerning information and then use this info. to render text using Opengl Api and texture atlas.

Kerning information related query.
Hi , I would like to use the kerning information(offline) to perform the rendering of text(run time) My use case is as follows: - Retrieve the kerning information for a given true type font and store it in some file. [ offline ] - Use the kerning information to perform the text rendering, using OpenGL API. [ run time ] Does anybody has sample code to refer for the above use case? Thankyou for any help! Thanks, Balakrishna.

Hi, We want to create fonts using pixelsize of the order of 14, which would eventually be displayed on DPI 114 display device. However, the fonts are not looking smoother at this pixel size.

[ft] Question on https://www.freetype.org/freetype2/docs/tutorial/example2.cpp
The code in https://www.freetype.org/freetype2/docs/tutorial/example2.cpp demonstrates the generation of colored outlines. The code generates RGBA per pixel, ie 4 bytes per pixel. For my project, I need to generate only 2 bytes per pixel. Ie., Luminance-alpha format. Can somebody please help me to know how to do this? Thanks, Bala.
