Detailed Description

Resource class.

Library: xviews or winviews or mviews (mutually exclusive)

Defines a color pattern. This can be used in a filling operation when a colored fill pattern is desired.

Constructor & Destructor Documentation

IlvColorPattern() [1/2]

IlvColorPattern::IlvColorPattern	(	IlvDisplay *	display,
		IlvDim	w,
		IlvDim	h,
		IlUShort	depth,
		unsigned char *	data
	)

Constructor.

This constructor initializes a new IlvColorPattern object with a bitmap that is defined by the indicated data.

Parameters

display	The display where this color pattern is defined.
w	The width of this color pattern.
h	The height of this color pattern.
depth	The depth of this color pattern.
data	The data that defines this color pattern. This data must be packed into 16-bit words from left to right in a most significant bits first manner, and each scan line, stored from top to bottom, must be padded to 16 bits.

IlvColorPattern() [2/2]

IlvColorPattern::IlvColorPattern

(

IlvBitmap *

bitmap

)

Constructor.

This constructor initializes a new IlvColorPattern object with a pre-allocated bitmap.

Parameters

bitmap

The bitmap that defines this color pattern. This bitmap is internally copied (it is therefore not locked).

Member Function Documentation

depth()

IlUShort IlvColorPattern::depth ( ) const

virtual

Retrieves the depth (number of bits that define a pixel value) of this pattern.

Returns

The depth of this pattern. This value is always 1 for instances of IlvPattern, but this member function can return a different value for an instance of IlvColorPattern, which is a subclass of IlvPattern.
