Re: [ft] [ft-devel] Regarding Colored Emoji

Hi Behdad,

 One more question, bitmap retunred by FreeType will consist of complete PNG file with file header etc or it will be only RBB encoded data?

Hi Behdad,

 Thank you for the guidence, I was thinking of resizing after debugging about the available strikes in FreType but was not very sure what to use for the same. I was using it on Windows to make one demo application, will add libPNG to windows project and try your suggestions.

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?
