5.31.4.1 on2sc overlay_options_GetMaskPixelRGB (FLIX2HANDLE flix, uint8_t ∗ pMaskPixelR,
uint8_t ∗ pMaskPixelG, uint8_t ∗ pMaskPixelB)
Return the Red, Green, and Blue component values of the mask pixel.
Parameters:
← flix Handle to the flix engine returned from Flix2_Create() or Flix2_CreateEx()
→ pMaskPixelR pointer to variable that will receive the R value
→ pMaskPixelG pointer to variable that will receive the G value
→ pMaskPixelB pointer to variable that will receive the B value
Return values:
ON2_OK the color component values were retrieved successfully
ON2_INVALID_PARAMS a precondition failed
ON2_NET_ERROR the underlying communication layer failed
Precondition:
flix is not NULL
pMaskPixelR is not NULL
pMaskPixelG is not NULL
pMaskPixelB is not NULL
Remarks:
This method returns the values set in previous call to overlay_options_SetMaskPixelRGB() , if no
coordinates were previously set, the Red, Green, and Blue component values will be set to 0.
Deprecated
Use the Filter Interface along with FE2_FILTER_OVERLAY and the FE2_OVERLAY_MASK_R ,
FE2_OVERLAY_MASK_G and FE2_OVERLAY_MASK_B parameters. This function will be re-
moved in a future release.
5.31.4.2 on2sc overlay_options_GetMaskPixelXY (const FLIX2HANDLE flix, int32_t ∗
pMaskPixelX, int32_t ∗ pMaskPixelY)
Return the X and Y coordinates of the mask pixel.
Parameters:
← flix Handle to the flix engine returned from Flix2_Create() or Flix2_CreateEx()
→ pMaskPixelX pointer to variable that will receive the X value
→ pMaskPixelY pointer to variable that will receive the Y value
Return values:
ON2_OK the coordinate values were retrieved successfully
