RE: Issue rendering fonts with fixed sizes

[stephan]

Thanks for the quick reply.

I had tried that before with the same error / result.

Is having the BDF module enabled required or some other options for font
with bitmap strikes to work correctly?

I just did some rendering with this exact same font.

Try FT_Select_Size with an index into the available-sizes table instead.
Since Noto Color Emoji only comes in one size, an index of 0 should work.

In my example
<https://github.com/ldo/harfpy_examples/blob/master/region-flags>, I found
it easier to use a graphics engine like Cairo to take care of the
font-sizing headaches for me.
