How do i scale an sprite entity to i.e 800x600 regardless of its actual defult size?

i think my.scale_x = 1 and my.scale_y = 1 is what your after play with the numbers to get the size you need

to do that i'd have to check the size in quants or somthing right?
im not sure how to do it

Warning: sprite scale may affect framerate
There may be precision problems.
Simple formula (pseudo-code):
scale_x = widthPx / bmap_width
scale_y = heightPx / bmap_height
Hypothetical code (untested):
Code:

---

bmap* im1_;
entity* e1;
/*******************************
	spritefScalePx
		_e: entity (or sprite) to scale
		_im: bmap passed to ent_create for _e (sprite entity)
		_widthPx: width in pixels to scale _e (sprite entity) 
		_heightPx: height in pixels to scale _e (sprite entity) 
*******************************/
function spritefScalePx(_e, _im, _widthPx, _heightPx) {
	if (_e == 0 || _im == 0 || _widthPx == 0 || _heightPx == 0) { 
		error("error: spritefScalePx(0 args)");
		return(0); 
	}
	e1 = _e;
	im1_ = _im;
	// this is the root of the function
	e1.scale_x = _widthPx / bmap_width(im1_);
	e1.scale_y = _heightPx / bmap_height(im1_);
	return(1);
}

One quant is one unit in WED and MED coordinates, and therefore one texture pixel at a 1.0 scale.
