## Member Function Documentation

static void csPackRGB::DiscardPackedRGB | ( | const uint8 * | rgb | ) | `[inline, static]`

Frees memory possibly allocated by PackRGBcolorToRGB().

Parameters:

  | rgb | Pointer to packed RGB data returned by PackRGBcolorToRGB().

Definition at line 106 of file packrgb.h.

References IsRGBcolorSane().

static void csPackRGB::DiscardUnpackedRGBcolor | ( | const csRGBcolor * | pixels | ) | `[inline, static]`

Frees memory possibly allocated by UnpackRGBtoRGBcolor().

Parameters:

  | pixels | Pointer to csRGBcolor array returned by UnpackRGBtoRGBcolor().

Definition at line 160 of file packrgb.h.

References IsRGBcolorSane().

static const uint8* csPackRGB::PackRGBcolorToRGB | ( | const csRGBcolor * | pixels,
|  | size_t | numPixels |
| ) |  |  | `[inline, static]`

Pack an array of csRGBcolor into a RGB byte array.

Remarks:
  May return `pixels`. May allocate memory. Free it using DiscardPackedRGB() when finished.

Parameters:

  | pixels | Source array of csRGBcolor data
  | numPixels | Number of pixels in the array

Returns:
  A byte array containing the source data packed as RGB.

Definition at line 90 of file packrgb.h.

static void csPackRGB::PackRGBcolorToRGBBuffer | ( | uint8 * | buf,
|  | const csRGBcolor * | pixels,
|  | size_t | numPixels |
| ) |  |  | `[inline, static]`

Pack an array of csRGBcolor into a RGB byte array.

Parameters:

  | buf | Buffer to pack the data into.
  | pixels | Source array of csRGBcolor data
  | numPixels | Number of pixels in the array

Definition at line 64 of file packrgb.h.

static uint8* csPackRGB::PackRGBpixelToRGB | ( | const csRGBpixel * | pixels,
|  | size_t | numPixels |
| ) |  |  | `[inline, static]`

Pack an array of csRGBpixel into a RGB byte array.

Alpha information is discarded!

Remarks:
  Allocates memory. Free it using delete[] when finished.

Parameters:

  | pixels | Source array of csRGBpixel data
  | numPixels | Number of pixels in the array

Returns:
  A byte array containing the source data packed as RGB.

Definition at line 174 of file packrgb.h.

static const csRGBcolor* csPackRGB::UnpackRGBtoRGBcolor | ( | const uint8 * | rgb,
|  | size_t | numPixels |
| ) |  |  | `[inline, static]`

Unpack a RGB byte array into an array of csRGBcolor.

Remarks:
  May return `pixels`. May allocate memory. Free it using sDiscardUnpackedRGBcolor() when finished.

Parameters:

  | rgb | Source array of RGB data
  | numPixels | Number of pixels in the array

Returns:
  An array containing the source data in csRGBcolor structs.

Definition at line 143 of file packrgb.h.

static void csPackRGB::UnpackRGBtoRGBcolor | ( | csRGBcolor * | buf,
|  | const uint8 * | rgb,
|  | size_t | numPixels |
| ) |  |  | `[inline, static]`

Unpack a RGB byte array into an array of csRGBcolor.

Parameters:

  | buf | Buffer to unpack the data into.
  | rgb | Source array of RGB data
  | numPixels | Number of pixels in the array
