Member Function Documentation

Clone()

virtual IChannelEx* IRhRdkRenderWindow::IChannelEx::Clone ( void  ) const

pure virtual

Makes a clone of the channel.

GetMinMaxValues()

virtual bool IRhRdkRenderWindow::IChannelEx::GetMinMaxValues ( OUT float &  fMin, OUT float &  fMax  ) const

pure virtual

Get the minimum and maximum values in the channel

GetValueEx()

virtual bool IRhRdkRenderWindow::IChannelEx::GetValueEx ( int  x, int  y, ComponentOrder  co, OUT void *  pData  ) const

pure virtual

Get value(s) from the channel.

Parameters

x	is the horizontal pixel position. No validation is done on this value. The caller is responsible for ensuring that it is within the frame buffer.
y	is the vertical pixel position. No validation is done on this value. The caller is responsible for ensuring that it is within the frame buffer.
co	is the component order of the destination data.
pData	accepts the data from the channel at the specified position and it must have enough room to accomodate the correct amount of data in the correct layout to match the pixel size. NOTE: RDK standard channels contain float data; the size of each pixel is always sizeof(float). For the special chanRGBA composite channel, the size of a pixel is 4 * sizeof(float).

Returns

true if successful, else false.

GetValueRect()

virtual bool IRhRdkRenderWindow::IChannelEx::GetValueRect ( int  x, int  y, int  width, int  height, int  stride, ComponentOrder  co, OUT void *  pData  ) const

pure virtual

Get a rectangle of values from the channel. The input parameters are checked for validity. If the rectangle is not fully inside the frame buffer, the function will fail.

Parameters

x	is the horizontal pixel position of the left edge.
y	is the vertical pixel position of the top edge.
width	is the width of the rectangle in pixels.
height	is the height of the rectangle in pixels.
stride	is the number of bytes between pixel rows in the destination buffer.
co	is the component order of the destination data.
pData	accepts the data from the channel starting at the specified position and it must have enough room to accomodate the correct amount of data in the correct layout to match the pixel size, the shape of the rectangle and the stride. NOTE: RDK standard channels contain float data; the size of each pixel is always sizeof(float). For the special chanRGBA composite channel, the size of a pixel is 4 * sizeof(float).

Returns

true if successful, else false.

Height()

virtual int IRhRdkRenderWindow::IChannelEx::Height ( void  ) const

pure virtual

Returns

the channel height.

Id()

virtual UUID IRhRdkRenderWindow::IChannelEx::Id ( void  ) const

pure virtual

Returns

the channel id.

Width()

virtual int IRhRdkRenderWindow::IChannelEx::Width ( void  ) const

pure virtual

Returns

the channel width.
