Image Structure

Texture maps and bitmaps are defined using pixel images (or pixmaps). To specify a pixel image, you fill in an image structure, defined by the TQAImage data structure.



 
struct TQAImage {

    long                                width;

    long                                height;

    long                                rowBytes;

    void                                *pixmap;

};

typedef struct TQAImage TQAImage;

width: The width, in pixels, of the pixmap.
height: The height, in pixels, of the pixmap.
rowBytes: The distance, in bytes, from the beginning of one row of the image data to the beginning of the next row of the image data. (For some low-cost accelerators, setting the value in this field to the product of the value in the width field and the pixel size improves performance.)
pixmap: A pointer to the image data.
