When a picture annotation item is set to the fixed size mode,
and has a callout anchor set, always place the annotation itself
at a fixed offset from the callout anchor. This mimics the
behavior of the old SVG annotation decoration.
Allows rendering a marker symbol below the endpoint of the balloon
callout. Designed to allow balloon callouts to reproduce the same
visual appearance as the older annotation framework items.
Allows using the widget in a QgsTextRenderer HTML subset mode,
where only functionality supported by QgsTextRenderer is
exposed in the widget. Also add a Plain Text mode.
sip doesn't use the standard Python staticmethod type for defining
static methods, which means that standard means of testing
for a static method (like `isinstance(..., staticmethod)`) fail
with any PyQGIS static methods.
This causes issues with lint tools, which incorrectly flag
calls to QGIS static methods as missing self arguments. It also
breaks detection of static methods in the sphinx PyQGIS docs,
so all static methods are shown as non-static.
Work around this in sipify, by wrapping unambiguously static
methods in staticmethod wrappers.
Allows creating of callout lines (or bubble callouts) which
link the text to a map location. To create a callout, users
select the text item and then drag out the central x node
to the desired callout end point.
Callout styles can be modified through the layer styling panel.
Adds a new "Linked layer" setting to the render page for annotation
layers, which allows users to optionally set a linked visibility
layer for the annotation layer. If set, then the annotations will
only be drawn when the linked layer is visible in the map.
This is designed to mimic the similar linked layer option for
the older annotation framework, in order to close the feature
gap between old vs new annotations
