TRgb | Color() |
TInt | Pixel() |
Specifies which pixels should be treated as transparent in a bitblt operation that supports transparency.
This is used by the TGopBitBltTransparent and TGopScaledBitBltTransparent graphics operations.
For the possible transparency types, see the TTransparencyType enumeration.
An object of this class is specified when constructing a TGopBitBltTransparent or TGopScaledBitBltTransparent.

TGopTransparency | ( | TTransparencyType | aType | ) | [inline] |
Constructor with a transparency type. iParam is initialised to zero.
Parameter | Description |
---|---|
aType | The transparency type. |
TGopTransparency | ( | TInt | aPixelValue | ) | [inline] |
Constructor with a pixel value. The type is initialised to ETransparentPixel. Any pixel that has a value equal to aPixelValue is treated as transparent. aPixelValue is the bit pattern of the pixel as stored in the bitmap.
Parameter | Description |
---|---|
aPixelValue | The pixel value. |
TInt | Pixel | ( | ) | const [inline] |
Gets the value of the colour as a TInt that is treated as transparent. This is the value of iParam.
Returns: The colour that is treated as transparent. This is the bit pattern of the colour as stored in the bitmap.
