A question about FT_Pixel_Mode

[Michael Wachs]

Hello,

My goal:

I use the freetype library (version 2.10.1) to convert TTF fonts to a proprietary format.
I want to convert the fonts to different pixel formats: 1-, 2-, 4- and 8-bits.
Converting to 1- and/or 8-bits is easy by using the options "FT_LOAD_...".
But there is no way to convert to 2- and 4-bits.
I found a very useful feature to me "FT_Pixel_Mode".
But there is no way to convert the bitmap format when loading/rendering the glyphs.
There is only one way to convert the glyph bitmap from these formats to a bitmap with 8-bits pixels by using "FT_Bitmap_Convert" but not versa.

Do I see this right?

Thanks in advance,
Michael
