FreeType doesn't resize bitmap images. Noto Sans Color has two strikes, at
55ppem and 109ppem. You are supposed to query the available sizes from
FreeType, choose the smallest size larger than your desired size,
FT_Set_Char_Size to the chosen size, load glyph, and use whatever imaging
library you have to resize the image.
What platform are you using?
