# IMAGESIZE, IMAGESIZE_W (W*S)

Graphics Functions: Return the number of bytes needed to store the image inside the specified bounding rectangle. IMAGESIZE is useful for determining how much memory is needed for a call to GETIMAGE.

## Module

USE IFQWIN

result = IMAGESIZE (x1,y1,x2,y2)

result = IMAGESIZE_W (wx1,wy1,wx2,wy2)

x1, y1 | (Input) INTEGER(2). Viewport coordinates for upper-left corner of image.
x2, y2 | (Input) INTEGER(2). Viewport coordinates for lower-right corner of image.
wx1, wy1 | (Input) REAL(8). Window coordinates for upper-left corner of image.
wx2, wy2 | (Input) REAL(8). Window coordinates for lower-right corner of image.

## Results

The result type is INTEGER(4). The result is the storage size of an image in bytes.

IMAGESIZE defines the bounding rectangle in viewport-coordinate points ( x1, y1) and ( x2, y2). IMAGESIZE_W defines the bounding rectangle in window-coordinate points ( wx1, wy1) and ( wx2, wy2).

IMAGESIZE_W defines the bounding rectangle in terms of window-coordinate points ( wx1, wy1) and ( wx2, wy2).

## Example

See the example in GETIMAGE.
