fg_colors()
|
Returns the display driver's color depth in bits per pixel.
|
|
fg_defpal()
|
Creates a logical palette containing Fastgraph's default colors.
|
|
fg_getcolor()
|
Returns the current color, as defined in the most recent call to fg_setcolor() or fg_setcolorrgb().
|
|
fg_getdacs()
|
Retrieves the red, green, and blue color components of a contiguous block of color entries in the active logical or virtual palette. Each color component is a value between 0 and 255; increasing values produce more intense colors. Reading many color values with fg_getdacs() is considerably faster than doing so individually with fg_getrgb().
|
|
fg_getdepth()
|
Returns the active virtual buffer's color depth in bits per pixel.
|
|
fg_getrgb()
|
Returns the red, green, and blue color components for a specified entry in the active logical or virtual palette. Each color component is a value between 0 and 255; increasing values produce more intense colors.
|
|
fg_logpal()
|
Creates a logical palette containing the specified colors.
|
|
fg_mapdacs()
|
Translates color values from the "0 to 63" range used by DOS 256-color graphics modes to the "0 to 255" range used by Windows.
|
|
fg_maprgb()
|
Converts RGB color components to a suitable color value. When used with a 256-color virtual buffer, finds the closest matching color in the logical palette.
|
|
fg_modeset()
|
Dynamically defines the display settings (resolution and color depth).
|
|
fg_modetest()
|
Checks if the user's system supports a given display resolution and color depth combination.
|
|
fg_realize()
|
Loads the specified logical palette into the current device context and maps its colors to the system palette (this process is called realizing a logical palette). After an application realizes a logical palette, pixels in virtual buffers will appear in those colors when displayed.
|
|
fg_setcolor()
|
Establishes the current color by specifying a logical palette index for 256-color virtual buffers, or an encoded RGB value for direct color virtual buffers.
|
|
fg_setcolorrgb()
|
Establishes the current color by specifying its RGB color components.
|
|
fg_setdacs()
|
Defines the color values for a block of contiguous entries in the active logical or virtual palette by specifying their red, green, and blue color components. Defining many color values with fg_setdacs() is considerably faster than doing so individually with fg_setrgb().
|
|
fg_setrgb()
|
Defines the color values for a single entry in the active logical or virtual palette by specifying its red, green, and blue color components.
|
|
fg_unmaprgb()
|
Extracts the red, green, and blue color components from an encoded 16-bit or 32-bit RGB color value.
|
|
fg_vbcolors()
|
Copies the colors from the current logical palette into the active virtual buffer's color table (meaningful only for 256-color virtual buffers). This defines a new set of colors for the active virtual buffer.
|
|
fg_vbdepth()
|
Defines the default virtual buffer color depth in bits per pixel.
