Hi,

?

I'm writing a quick script to serialize a curve defined in an acv from Photoshop to a string compatible with the GRAY_CURVE parameter in an ink descriptor file. Adobe's defines each curve point pair as the output value followed by the input value. Additionally, each coordinate is a value in the range of 0–255.

?

Two questions:

?

1. Can anyone confirm whether GRAY_CURVE expects the format input;output or output;input?

2. Does 255 == 100 in GRAY_CURVE or is the value similar to the ink percentage in Photoshop where 255 == 0?

?

Thanks.
