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.
