1659 are stored in the same format/depth as the image data in a bKGD or tRNS
1681 transparency information in a tRNS chunk. This is most useful on
1700 added. It expands the sample depth without changing tRNS to alpha.
1706 the tRNS chunk is present, A means an alpha channel is present, and O
1707 means tRNS or alpha is present but all pixels in the image are opaque.

1768 If you do this, any input with a tRNS chunk will be expanded to
3012 other transformations because in the case of paletted images the tRNS
3013 chunk data has to be inverted before the tRNS chunk is written. If
3014 your image is not a paletted image, the tRNS data (which in such cases
