Property: CompressionLevel

(TSaveFmx2D_Png)

Specifies the compression level of a Portable Network Graphics (PNG) file for the TSaveFmx2D_Png component.

Syntax:

type

{ Defined in the pfmxSave2D_Png unit }

TPngCompressionLevel = (pclFastest, pclDefault, pclMaximum);

property CompressionLevel: TPngCompressionLevel;

Description:

The Portable Network Graphics (PNG) uses a non-patented lossless data compression method known as DEFLATE. The property specifies what level of compression should be used to save a barcode symbol to a Portable Network Graphics (PNG) file. It can be one of these value (defined in the pfmxSave2D_Png unit):

• pclFastest: Uses the fastest compression. The compression operation should complete as quickly as possible, even if the resulting file is not optimally compressed.
• pclDefault: Uses the default compression level. It represents a balance between the compression ratio and compression speed.
• pclMaximum: Uses the maximum compression. The compression operation should be optimally compressed, even if the operation takes a longer time to complete.
