scaled value of the referenced IMAGE entity (in DXF)

[FELIXJMELO]

Can you know the scale value in DXF of the IMAGE object?

Quick answer is probably yes, you would have to find the image entry in the file then look for the DXF code for the scale.

Just type this on command line and look at the assoc codes. (entget (car (entsel))) pick a image.

As far I know there is no DXF Group code from which you can get the scale value of the IMAGE object directly .......

Check >>THIS<< 

You have to do this to get the scale value of the IMAGE object.......

(defun C:RAS_SCALE( / Ent U_Vec Pix_Size) 
(setq Ent (entget (car (entsel "\nSelect Raster Object: ")))) 
(if Ent 
	(if (= (cdr (assoc '0 Ent)) "IMAGE") 
		(progn 
			(setq U_Vec (distance '(0.0 0.0 0.0) (cdr (assoc 11 Ent)))) 
			(setq Pix_Size (car (cdr (assoc 13 Ent)))) 
			(princ (strcat "\nImage Scale: " (rtos (* U_Vec Pix_Size) 2 4))) 
		) 
	) 
) 
(princ)
)

or using vla.........try like this (if an object has Scalefactor property).......

(vla-get-Scalefactor (vlax-ename->vla-object (car(entsel))))
