Example 22 with Row

use of com.codename1.db.Row in project CodenameOne by codenameone.

the class CN1ImageLuminanceSource method getRow.

// Instead of multiplying by 306, 601, 117, we multiply by 256, 512, 256, so that
// the multiplies can be implemented as shifts.
// 
// Really, it's:
// 
// return ((((pixel >> 16) & 0xFF) << 8) +
// (((pixel >>  8) & 0xFF) << 9) +
// (( pixel        & 0xFF) << 8)) >> 10;
// 
// That is, we're replacing the coefficients in the original with powers of two,
// which can be implemented as shifts, even though changing the coefficients slightly
// alters the conversion. The difference is not significant for our purposes.
