Purpose: The ImageGenerator node generates color image maps of various formats.
Usage: Instantiate the class and create an image generator node
Data output: Image maps
Overview:
The ImageGenerator node generates color image maps of various formats, such as the RGB24 image format. Call its SetPixelFormat() method to set the image format to be generated.
The other important function here is GetMetaData(), which, as in other generator nodes, gets the image frame object, through which you can access all the properties and the actual data of the saved frame.
void xn::ImageGenerator::GetMetaData |
( |
ImageMetaData & | metaData | ) |
const |
|
inline |
Gets the image generator node's latest frame object, saving it in the xn::ImageMetaData object. This frame object is a snapshot of the generated image map data and its associated configuration information at a certain point in time. This saved frame object provides fast and easy access to the image generator node's data and configuration information.
- Parameters
-
[out] | metaData | Structure to be filled with the frame object. |
Remarks:
This method is central in the use of the ImageGenerator node. Once the ImageGenerator node is generating data, after each 'Update Data' call, the application calls this method to get the node's frame object, which contains the data and all its associated properties.
Sets the ImageGenerator node's current 'pixel color' format. This format is used for generating the next frame.
- Parameters
-
[in] | Format | The format to set. |
Remarks
As an example of a pixel color format, the RGB24 image format has one byte for red, one byte for green, and one byte for blue.
When reading the generated data you must use the appropriate 'get' function, e.g., call RGB24Data() to read data generated as the RGB24Data format.
It is the user responsibility to check first if the pixel format is supported by calling xn::ImageGenerator::IsPixelFormatSupported().
