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.
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

This adds a new annotation item type for rendering paragraphs
of text inside a rectangle
Options are present for:
- Text format
- Horizontal and vertical alignment
- Margins
- Background and frame symbol
Makes the API more flexible for future use. We only expose a single
tolerance value in the UI, but in future we could expose the
separate tolerances if desired (but be wary of UI bloat!!)
Allows pixels with color components just outside of the specified
RGB values to also be treated as transparent pixels
Useful for photographs or compressed rasters where a range of color
values must be made transparent
Can render SVG or raster images as items in an annotation layer.
Options are present for:
- Locking the picture's aspect ratio
- Drawing with a background symbol
- Drawing with a border symbol
- Linked or embedded pictures
Adjust the QgsTextRenderer::calculateScaleFactorForFormat logic
so that small text is scaled up to at least 50 pixels when
calculating text metrics
This avoids tiny differences in calculated text metrics for small
text from affecting how text wrapping is calculated, which can
otherwise result in words at the end of lines "bouncing" from line
to line as layouts and maps are zoomed out
