2.1.5 ColorAdjustment Enumeration

  • Article

The ColorAdjustment enumeration is used to specify how the output image is prepared when the stretch mode is HALFTONE.

 typedef  enum 
 {
   CA_NEGATIVE = 0x0001,
   CA_LOG_FILTER = 0x0002
 } ColorAdjustment;

CA_NEGATIVE: Specifies that the negative of the original image SHOULD be displayed.

CA_LOG_FILTER: Specifies that a logarithmic process SHOULD be applied to the final density of the output colors. This will increase the color contrast when the luminance is low.
