COP nodes that have to create layers use context options to determine the default settings of those layers. The global context option can be overridden for nodes inside a network by turning on these options. For more information, see Default COP Network settings.
For information about the COP network, see Copernicus.
Parameters ¶
Default Resolution
Sets the context option for default_xres and default_yres.
This is the size of layers that don’t have an explicit size set.
The default is 1024×1024.
Default Pixel Scale
Sets the context option default_pixelscale. This is a scale for
the size of the pixels in the image, causing the image to cook at
a fractional effective resolution, but not changing any
pixel-relative values.
Default Border
Sets the context option default_border. This is an integer
context option which encodes what the border type of new layers
should be.
Constant
Outside the layer evaluates to 0.
Clamp
Outside the layer evalutes to the closest pixel in the layer.
Mirror
Outside values reflect off the boundaries.
Wrap
Outside values wrap around.
Default Precision
Sets the context option default_precision to control how many
bits are used for each channel.
16-bit
A value of 16 meaning to default to half-precision.
32-bit
A value of 32 meaning to default to full-precision.
Tile Visualization
When evaluating the geometry for the 3D viewport, attach the tilevis primitive property to have it displayed with a repeating pattern. This makes it easy to see how well the pattern will tile and to verify operations haven’t made it not tile.
