write an image and compare it to an expected result

Returns the base path containing the reference images.

This defaults to an internal QGIS test data path, but can be changed via :py:func:`~QgsRenderChecker.setControlImagePath`.

%Docstring
|

Sets the base directory ``name`` for the control image (with control image path
|
|
suffixed).
|

The path to the image will be constructed like this:

:py:func:`~QgsRenderChecker.controlImagePath` + '/' + control name + '/' + control name + '.png'

Sets the path prefix where the control images are kept.

This will be appended to :py:func:`~QgsRenderChecker.controlImagePath`.

Sets the file name of the rendered image generated by the test.

%Docstring

Returns the path of the rendered image generated by the test.

This method will return either the path set with :py:func:`~QgsRenderChecker.setRenderedImage` or generated in :py:func:`~QgsRenderChecker.runTest`.

Set tolerance for color components used by :py:func:`~QgsRenderChecker.runTest` and :py:func:`~QgsRenderChecker.compareImages`.

Default value is 0.

Test using renderer to generate the image to be compared.
|

|
|
:param testName: - to be used as the basis for writing a file to
|
|
e.g. /tmp/theTestName.png
|
|
:param mismatchCount: - defaults to 0 - the number of pixels that
|
|
are allowed to be different from the control image. In some cases
|
|
rendering may be non-deterministic. This parameter allows you to account
|
|
for that by providing a tolerance.

make sure to call setExpectedImage and setMapRenderer first

Test using two arbitrary images (map renderer will not be used)

e.g. /tmp/theTestName.png
|
|
:param mismatchCount: - defaults to 0 - the number of pixels that

are allowed to be different from the control image. In some cases

rendering may be non-deterministic. This parameter allows you to account

bool isKnownAnomaly( const QString &diffImageFile );
|
|
%Docstring
|
|
Gets a list of all the anomalies. An anomaly is a rendered difference
|
|
file where there is some red pixel content (indicating a render check
|
|
mismatch), but where the output was still acceptable. If the render
|
|
diff matches one of these anomalies we will still consider it to be
|
|
acceptable.

:return: a bool indicating if the diff matched one of the anomaly files

%Docstring
|

Draws a checkboard pattern for image backgrounds, so that opacity is visible

|
without requiring a transparent background for the image
|

Returns the path to the expected image file

%Docstring
|
|
Call this to enable internal buffering of dash messages. You may later call
|

:py:func:`~QgsRenderChecker.dashMessages` to get access to the buffered messages. If disabled (default)
|
|
dash messages will be sent immediately.

Gets access to buffered dash messages.

Only will return something if you call enableDashBuffering( ``True`` ); before.

:return: buffered dash messages

Compare two WKT strings with some tolerance
