class IlvDisplay
 

Detailed Description

Resource class.

Library: display

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

See Also
IlvPalette, IlvDisplay::defaultPattern, IlvDisplay::getColorPattern.

Constructor & Destructor Documentation

IlvColorPattern::IlvColorPattern ( IlvDisplay ,
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
displayThe display where this color pattern is defined.
wThe width of this color pattern.
hThe height of this color pattern.
depthThe depth of this color pattern.
dataThe 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::IlvColorPattern ( IlvBitmap bitmap)

Constructor.

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

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

Member Function Documentation

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.

Reimplemented from IlvPattern.
