mDCV example data has bug #539
Description
mDCV Example 6 data has bug:
https://www.w3.org/TR/png-3/#example-6
It reads:
- Actual values: (0.3127, 0.3290)
- Stored decimal values: {15635, 16450}
- Stored Hexadecimal values: {3C 05, 40 42}
The last line should read:
- Stored Hexadecimal values: {3D 13, 40 42}
(I happened to find this by hard-coding the example data into a test file, and then noticing the test failed).
