This allows a range of new possibilities, including:
- models with static outputs for child algorithms, e.g. always saving
a child algorithm's output to a geopackage or postgres layer
- models with expression based output values for child algorithms, e.g.
generating an automatic file name based on today's date and saving
outputs to that file
These are a visual guide, allowing designers to create logical groups
of algorithms relating to a single task ("eg 'Prepare data')
The title and color of the group boxes can be customized
show the obtained values for all child algorithm outputs within the designer
canvas
This gives users better tools for debugging models - they can see exactly
what values were output by the child algorithms and flowed into other
parts of their model
This algorithm saves the contents of the execution log (right up to
the point in the model at which the 'save log' algorithm executes)
to a file.
It can be used to automatically store the debugging log when running
models for later reference and transparency.
This new renderer draws contour lines that are calculated on the fly
from the source raster band. It is possible to set interval of contour
lines and symbol used for drawing.
In addition there is support for "index contours" - contour lines
with higher interval, typically drawn with a wider line symbol.
If we generate contour lines on input raster block with the same size as our
output raster block, the generated lines would contain too much detail.
This detail can be reduced by the "downscale" factor - this will request
lower resolution of the source raster.
The Random points on lines algorithm supplements the existing "Random points along line" algorithm, and will prove to be more useful to the majority of users than the "original".
Features:
The points are distributed randomly over the lines based on "along the line" distance, meaning that the distribution of the points will be flat over the length of the line (each place on the feature has the same probability of being "hit").
The Random points along line, on the other hand, uses a line segment based approach, meaning that the density will depend on the segment length (short segments will have a higher point density than longer ones).
