Function Documentation

void Dali::Pixel::GetAlphaOffsetAndMask ( Format  pixelFormat,
int &  byteOffset,
int &  bitMask 
)

Returns the offset of the byte containing the alpha value from the start of the pixel data and the bitmask of that byte to get the alpha value.

For example, in case of Pixel::RGBA4444, byteOffset value is 1 and bitMask value is 0x0f. It means the second byte contains the alpha value and the last 4 bits of the byte is the alpha value.

Bitmask is zero if the pixelFormat does not support alpha.

Since:
2.4, DALi version 1.0.0
Parameters:
[in]pixelFormatThe pixel format
[out]byteOffsetThe byte offset of the byte containing the alpha value
[out]bitMaskThe bitmask of the byte to get the alpha value
unsigned int Dali::Pixel::GetBytesPerPixel ( Format  pixelFormat)

Returns The number of bytes per pixel for the specified pixel format.

Since:
2.4, DALi version 1.0.0
Parameters:
[in]pixelFormatThe pixel format
Returns:
The number of bytes per pixel
bool Dali::Pixel::HasAlpha ( Format  pixelformat)

Whether specified pixel format contains an alpha value.

Since:
2.4, DALi version 1.0.0
Parameters:
[in]pixelformatPixel format
Returns:
true if format has alpha, false otherwise
