Description

The operation draws a strings on the inImage aligning the inLocationAnchor location of the text at the inLocations of the inImage. The height of the font is fixed and equals 16 pixels.

Hints

Connect an image source to the inImage input. Drawing will be done on this image.
If you want to draw on an empty background, use EmptyImage filter before.
Define inStrings. This will be the primitives to be drawn.
For each of the strings also define its location by setting the inLocations input.
If the locations provided on the inLocations input are in a local coordinate system, also set the inLocationAlignment input.
Set inLocationAnchor do define how each of the strings should be aligned in relation to its location.
Define the font size by setting the inSize input. Recommended values are: 16, 32, 48, 64.
Leave the inColors input not set to have all the primitives drawn with random colors. Set a custom array of colors here to decide explicitly how each of the primitives should be drawn.
Set inForceRgb to True, if you want to get a 3-channel output regardless of what is on the input.
Set inDrawingStyle to control quality, opacity, thickness, filling, point shapes and sizes.
