Class Syntax

Parameters

Class Name BoxGridImage2d

Parameter Name Description Type Supported Values Default Value
input
outputType
OutputType defines the type of desired grid in the output image.
LINES The output image contains a binary grid.
CONTIGUOUS_REGIONS The output image contains a grid of connected labels.
SEPARATED_REGIONS The output image contains a grid of separated labels.
Enumeration LINES
input
imageSize
The dimensions in pixels of the output image. Vector2u32 != 0 {128, 128}
input
origin
The origin of the first full rectangular region to generate. Vector2u32 Any value {0, 0}
input
gridOffset
The X and Y side size of boxes to create in the output images. In CONTIGUOUS_REGIONS or SEPARATED_REGIONS mode, it represents the number of pixels between the top left corners of contiguous labels in each direction. In LINES mode, it represents the offset, in pixels, between consecutive lines in each direction. Vector2u32 != 0 {10, 10}
output
outputImage
The output 2d image containing the grid. Type depends of the type of the grid. Image nullptr

boxGridImage2dAlgo.setImageSize( {128, 128} );

boxGridImage2dAlgo.setGridOffset( {10, 10} );
boxGridImage2dAlgo.execute();

std::cout << "outputImage:" << boxGridImage2dAlgo.outputImage()->toString();
