Status

This change has been marked as submitted.


Review request for KDE Frameworks.


Repository: kimageformats


Description
-------

Implement fuzzy image matching in readtest

Images are converted to ARGB32 format, then each byte (ie: each pixel
channel) in the read image is allowed to deviate by some specified
amount from the corresponding byte in the expected image, to allow for
rounding errors etc.

By default, no deviation is permitted, but the XCF tests are allowed a
deviation of 1, as the alpha blending can result in rounding errors
(depending on whether hardware acceleration is used, for example).  In
the end, we are not too concerned about a small deviation that is
invisible to the human eye.

Extract QImage::Format parsing into its own header

Use the array-of-strings suggested by David Faure so that only one list
has to be maintained instead of three.

Testing
-------

imagedump still works.  Most tests still pass; note that the non-alpha pic tests fail without https://git.reviewboard.kde.org/r/116568/diff/ as the wrong format (ARGB32 instead of RGB32) is constructed.

This should make the xcf tests pass again on Jenkins.


Thanks,

Alex Merry
