Memory Device Structure

You specify a memory device using a memory device structure, defined by the TQADeviceMemory data type.



 
typedef struct TQADeviceMemory {

    long                                rowBytes;

    TQAImagePixelType                   pixelType;

    long                                width;

    long                                height;

    void                                *baseAddr;

} TQADeviceMemory;

rowBytes: The distance, in bytes, from the beginning of one row of the memory device to the beginning of the next row of the memory device.
pixelType: A value that specifies the size and organization of the memory associated with a pixel in the pixmap. See "Pixel Types" for information on the values you can assign to this field.
width: The width, in pixels, of the memory device.
height: The height, in pixels, of the memory device.
baseAddr: A pointer to the beginning of the memory device.
