SupportTransparency

Gets or sets a value indicating whether the encoder should support transparency. Note: Transparency support only works together with 32 bits per pixel. This option will change the default behavior of the encoder of writing a bitmap version 3 info header with no compression. Instead a bitmap version 4 info header will be written with the BITFIELDS compression.

Declaration

public bool SupportTransparency { get; set; }

Property Value

Type	Description
Boolean
