Hi,
Use RandomAccessReadBuffer and pass the array.
NonSeekableRandomAccessReadInputStream isn't for that.

Hi,
I've been using FontBox 2.x for some time, and just started dipping my toes
into 3.x to see if it will work for me. However, I'm running into an issue
parsing a TTF in memory. I have a byte[], which I was wrapping in a
ByteArrayInputStream and then passing to TTFParser.parse( ).
Now it looks like I need to wrap the BAIS in
a NonSeekableRandomAccessReadInputStream and pass that to TTFParser.parse(
), but it hits EOF immediately because it looks like the length is 0 (zero)
when it is checked prior to any reads. Should I be doing something
differently?
ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
TTFParser parser = new TTFParser(false);
try (NonSeekableRandomAccessReadInputStream input = new
NonSeekableRandomAccessReadInputStream(bais);
TrueTypeFont font = parser.parse(input)) {
// use font here
}
Thanks!
Daniel
