For some layer types (rasters, point clouds) this gives a much better
experience vs generating the profile completely upfront. (I.e. even
with super-detailed DEM layers the profile is now basically instant
to generate).
using a fill symbol below the elevation surface
This can be easier to interpret in some cases, and helps match expected
symbology conventions in certain disciplines.
elevation profile source
And use this to just redraw the existing results whenever a setting
relating only to the appearance of the profile chart is changed,
instead of regenerating the whole chart
all frames from the animation to a temporary directory
This avoids lengthy delays when trying to render a specific frame
from the animation, as most animation formats require us to
iterate through all preceding frames in order to retrieve a specific
frame. By iterating once in advance and saving the results out we
gain instant access to any individual frame from the animation.
Unlike setting a font's style via setNamedStyle(), these settings
will ensure that a font is always rendered in bold or italic regardless
of whether the font family actually has a bold or italic variant. A
"faux bold" or slanted text effect will be emulated by Qt, which may
result in poor quality font rendering.
(For this reason it is greatly preferred to call setNamedStyle() instead.)
This API is being added so that QgsTextFormat/QgsTextRenderer can
replicate the same font behaviour as the base QFont/QPainter classes
do, where faux bold/italic effects are possible.
(It's not exposed anywhere for user control!)
Eg if a font is built by calling .setBold/.setItalic and not
by QFont::setStyleName then this method will attempt to return
the equivalent style name.
Results are very platform dependent and font dependent, depending
on Qt's internal matching logic (hence no unit tests)
This:
- Allows users to turn on or off the visibility of layers from
the profile plot on a plot-by-plot basis (previously the layer
visibility was taken straight from the main canvas layer visibility)
- Allows users to rearrange the drawing order of layers in the plot
- Allows a shortcut to the layer elevation properties settings by
double clicking layers
- Provides a "legend" for the features visible on the plot
This now follows the approach used for bearing formats, where a user
can defined a default coordinate format for newly created projects
in the Settings - Options - Map Tools section.
New projects will inherit that setting, but the format can then
be changed through the Project Properties - Coordinate Format button.
This ultimately exposes more control to users for how coordinates
are formatted for a project, eg allowing them to control whether
direction suffixes are shown, and whether leading or trailing zeros
should be included.
symbology, and add checkbox to disable this in their elevation
properties page
This means that vector results in elevation profile charts will default
to showing features using their corresponding 2d renderer, allowing
eg categorized classes to be visible on the profile chart. (In the
case that a profile symbol type doesn't match the layer's renderer
symbol types, we just take the symbol color from the renderer)
Users can now indicate that a symbol should be treated as a animated
symbol, through the new "Animation Settings" option in the symbol
widget's Advanced menu.
This settings panel allows users to enable animation for the symbol
and set a specific frame rate at which the symbol should be redrawn.
When enabled, the @symbol_frame variable can be used in any
symbol data defined property in order to animate that property.
For instance, setting the symbol's rotation to the data defined
expression
@symbol_frame % 360
will cause the symbol to rotate over time. (with rotation speed
dictated by the symbol's refresh rate)
