Description

disp_distributiondisp_distributionDispDistributionDispDistributiondisp_distribution displays a distribution in the window. RowRowRowrowrow and ColumnColumnColumncolumncolumn define the position of the center of the graphic. ScaleScaleScalescalescale allows scaling of the graphic, whereby 1 means displaying all 256 values, 2 means displaying 128 values, 3 means displaying only 64 values, etc. Noise distributions can be generated with operations like gauss_distributiongauss_distributionGaussDistributionGaussDistributiongauss_distribution or noise_distribution_meannoise_distribution_meanNoiseDistributionMeanNoiseDistributionMeannoise_distribution_mean.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.
