RE: [ft] Please explain pixel modes

Correct, freetype never dabbles with colors, only pixel coverage. So when drawing an AA glyph you take the gray output from freetype and use as the alpha channel or luminance tex. What to put in the color components is up to you.

 

You haven’t missed the tutorials right? They’re invaluable when you get started. http://www.freetype.org/freetype2/docs/tutorial/step1.html

Subject: [ft] Please explain pixel modes

 

I'm new to freetype and I am currently doing my best to learn how to use it.

 

I was looking over the Pixel Mode documentation located here:

http://freetype.sourceforge.net/freetype2/docs/reference/ft2-basic_types.html#FT_Pixel_Mode

 

I'm having a bit of trouble understanding these pixel modes. It seems to me like everything comes in as grayscale and you have to apply a hue to the pixels yourself to give it color. Is this true? If not, what are the gray modes for? Are these masks that represent the alpha channel of each glyph?

 

Help is appreciated.
