* add demo file and start a short doc
* fix some annotations
* do not display hidden line (SIP_SKIP, delete)
* use a defined var for SIP_SKIP
* remove constructor definition in header
* fix comment after method definition in header
* add a test for sipify itself
Instead of requiring all linestrings to be constructed by
first creating QgsPointSequence (requiring creation or
conversion of points to QgsPointV2), allow construction
of LineStrings directly from vectors of values (fastest!)
or lists of QgsPoint.
Likely results in speedups for lots of geometry operations,
but using the same layer as earlier tested for densify
improvements the densify operation time dropped further
from 25 seconds to 15 seconds.
- Add QgsGeometry method to densify by distance
- Fix bug in processing algorithm which resulted in duplicate
vertices and incorrectly spaced extra vertices
Adds a new geometry class for Triangle geometries
Methods include orthocenter, bisectors, medians, medial, circumscribed (center,
radius), inscribed (center, radius)
Also adds make_triangle expression function for creating triangles
Instead of creating them for all items when composer window
is opened, instead just create and destroy them when
required. None are too heavy to have a noticable delay
when selecting items, but in contrast keeping them around
forever is wasteful on memory.
Also clean up a lot of duplicate composer/composition
code and remove unnecessary signals from api (use a single
itemAdded signal instead of multiple signals for every
item type)
This adds a new QgsLayoutManager class which is used for
storage and serializing/deserializing of compositions.
A QgsLayoutManager is attached to QgsProject. This allows
core code to access the compositions attached to a project.
The intention is to move all handling of compositions from
app to core, making it easy for server to access project
compositions without resorting to fragile xml parsing.
This enum value has not been in use since filter rects were
separated from other filter types. Leaving it in API is confusing
and leads to incorrect use.
