cImage() [3/3]

cImage::cImage	(	const cSize &	Size,
		const tColor *	Data = NULL )

Creates an image with the given Size and allocates the necessary memory to copy the pixels pointed to by Data, which is a sequence of (Size.Width() * Size.Height()) tColor values.

If Data is NULL, the allocated memory is not initialized. The alpha value of the Image's pixels is taken into account, so it has to be greater than 0 for the image to be visible.

Clear()

void cImage::Clear

(

void

)

Clears the image data by setting all pixels to be fully transparent.

Definition at line 1131 of file osd.c.

References data, Height(), and Width().

Data()

const tColor * cImage::Data ( void ) const

inline

Definition at line 437 of file osd.h.

References data.

Referenced by cImage(), cImage(), and cPixmapMemory::DrawImage().

Fill()

void cImage::Fill

(

tColor

Color

)

Fills the image data with the given Color.

Definition at line 1136 of file osd.c.

References data, Height(), and Width().

GetPixel()

tColor cImage::GetPixel ( const cPoint & Point ) const

inline

Returns the pixel value at the given Point.

For performance reasons there is no range check here, so the caller must make sure that the Point is within the images size.

Definition at line 438 of file osd.h.

References data, size, cPoint::X(), and cPoint::Y().

Height()

int cImage::Height ( void ) const

inline

Definition at line 436 of file osd.h.

References size.

Referenced by Clear(), DrawImages(), and Fill().

SetPixel()

void cImage::SetPixel ( const cPoint & Point, tColor Color )

inline

Sets the pixel at the given Point to Color.

For performance reasons there is no range check here, so the caller must make sure that the Point is within the images size.

Definition at line 442 of file osd.h.

References data, size, cPoint::X(), and cPoint::Y().

Referenced by cTrueColorDemo::Action(), and DrawImages().
