centerOnScreen()

void QQuickVisualTestUtils::centerOnScreen

window

)

Here is the call graph for this function:

compareImages()

bool QQuickVisualTestUtils::compareImages	(	const QImage &	ia,
		const QImage &	ib,
		QString *	errorMessage )

Compares ia with ib, returning true if the images are equal. If they are not equal, false is returned and errorMessage is set.

A custom compare function to avoid issues such as: When running on native Nvidia graphics cards on linux, the distance field glyph pixels have a measurable, but not visible pixel error. This was GT-216 with the ubuntu "nvidia-319" driver package. llvmpipe does not show the same issue.
