This test verifies the support for gamma correction of displayed PNG
|
|
|
27 |
images. Several different images are displayed one above the other;
|
|
|
28 |
if gamma correction is correctly performed based on the values in
|
|
|
29 |
the gAMA chunk in the PNG file, the resulting displayed values are
|
|
|
30 |
the same in all of the files (except for rounding error, which gives
|
|
|
31 |
some artefacts at the right side of the lowest two images due to the
|
|
|
32 |
very high levels of gamma correction needed for this test).
