Hi every1,
I need to find that a given png image is an 'alpha channel'
or
'monocolor' image. (though i dont have much idea, about
what is that ?)
I have the data for the color type of the image and the
specification
says that:
Color Allowed Interpretation
Type Bit Depths
0 1,2,4,8,16 Each pixel is a grayscale sample.
2 8,16 Each pixel is an R,G,B triple.
3 1,2,4,8 Each pixel is a palette index;
a PLTE chunk must appear.
4 8,16 Each pixel is a grayscale sample,
followed by an alpha sample.
6 8,16 Each pixel is an R,G,B triple,
followed by an alpha sample.
which one of them are monocolor and which are the alpha
channel?
I think respective to colortype 0 and 2 are monocolor and
rest alpha
channel... is that correct.
Thanks for any info.
Regards,
Nishant
