scanline	back to summary
public final int[] scanline The 'scanline' is an array of integers, corresponds to an image line (row). Except for 'packed' formats (gray/indexed with 1-2-4 bitdepth) each `int` is a "sample" (one for channel), (0-255 or 0-65535) in the corresponding PNG sequence: `R G B R G B...` or `R G B A R G B A... or g g g ... or i i i (palette index)` `For bitdepth=1/2/4 , and if samplesUnpacked=false, each value is a PACKED byte!` `To convert a indexed line to RGB balues, see ImageLineHelper.palIdx2RGB() (you can't do the reverse)`

public final int[] scanline

The 'scanline' is an array of integers, corresponds to an image line (row).

Except for 'packed' formats (gray/indexed with 1-2-4 bitdepth) each int is a "sample" (one for channel), (0-255 or 0-65535) in the corresponding PNG sequence: R G B R G B... or R G B A R G B A... or g g g ... or i i i (palette index)

For bitdepth=1/2/4 , and if samplesUnpacked=false, each value is a PACKED byte!

To convert a indexed line to RGB balues, see ImageLineHelper.palIdx2RGB() (you can't do the reverse)
