Printing:PNG Compression Level Property
Short Name: Pr.PNGCmpLvl
Installed With: Base Package
Class: Application Properties
Number between 0 and 9 that specifies the level of compression you want for the PNG file for graphics in VIs printed either interactively or with the Print:VI To HTML method. The quality of the graphic is not affected by the compression, but the graphic file size and speed of compression are affected by this value. Valid values range from 0 to 9 and balance file compression with speed. 0 designates no compression. 1 designates less compression, but faster speed. 9 designates high compression, but slower speed. If you enter –1, LabVIEW selects the best combination of speed and compression.
