PALETTEENTRY structure

  • Artykuł

The PALETTEENTRY structure specifies the color and usage of an entry in a logical palette. A logical palette is defined by a LOGPALETTE structure.

Syntax

typedef struct tagPALETTEENTRY {
  BYTE peRed;
  BYTE peGreen;
  BYTE peBlue;
  BYTE peFlags;
} PALETTEENTRY;

Members

  • peRed
    The red intensity value for the palette entry.

  • peGreen
    The green intensity value for the palette entry.

  • peBlue
    The blue intensity value for the palette entry.

  • peFlags
    Indicates how the palette entry is to be used. This member may be set to 0 or one of the following values.

    Value Meaning
    PC_EXPLICIT

    Specifies that the low-order word of the logical palette entry designates a hardware palette index. This flag allows the application to show the contents of the display device palette.
    PC_NOCOLLAPSE

    Specifies that the color be placed in an unused entry in the system palette instead of being matched to an existing color in the system palette. If there are no unused entries in the system palette, the color is matched normally. Once this color is in the system palette, colors in other logical palettes can be matched to this color.
    PC_RESERVED

    Specifies that the logical palette entry be used for palette animation. This flag prevents other windows from matching colors to the palette entry since the color frequently changes. If an unused system-palette entry is available, the color is placed in that entry. Otherwise, the color is not available for animation.
