DECLARE FUNCTION DQBsize (BYVAL x1, BYVAL y1, BYVAL x2, BYVAL y2)x1 - Upper left corner x coordinate
y1 - Upper left corner y coordinate
x2 - Lower right corner x coordinate
y2 - Lower right corner y coordinate
An INTEGER value holding the sprite size in bytes
DQBsize returns the number of bytes needed to store the image contained into the box given by (x1,y1)-(x2,y2) with DQBget. This value can be then used to dimension arrays to store the sprite data for the DQBget and DQBput routines. Remember that the array is made of INTEGERs while this function returns the number of bytes; just divide its result by 2 to obtain the array dimension.
This function can be useful when storing several sprites into the same array, to know the exact offset of each frame.
