DRAW_FIXED_GRID

DrawFixedGridStep is a pipeline step that draws a grid on an image. This is similar to DrawGridStep but the corner x or y location values are hard coded into the configuration (via points), instead of coming dynamically from the input data instance.

Configs

Descriptions

imageName

Name of the input image key from the previous step. If set to null, it will try to find any image in the incoming data instance.

points

gridX

The number of grid segments between (top left and top right) and (bottom left and bottom right).

gridY

The number of grid segments between (top left and bottom left) and (top right and bottom right).

coordArePixels

If true, the points are in pixels coordinates (0 to width-1) and (0 to height-1). If false, they are 0.0 to 1.0 (fraction of image height or width).

borderColor

Color of the border. The color can be a hex/HTML string like #788E87, an RGB value like - rgb(128,0,255) or it can be from a set of predefined HTML color names: white, silver, gray, black, red, maroon, yellow, olive, lime, green, aqua, teal, blue, navy, fuchsia, purple.
