Macro Definition Documentation

IMG2OVER

#define IMG2OVER	(		IO,
			iv,
			iu,
			v,
			u
	)

Value:

u = (double) (IO).overumin + (iu) / (double) ((IO).uistep); \
    v = (double) (IO).overvmin + (iv) / (double) ((IO).vistep);

Speed up pixel index macro

This macro is the same as the function img2over but faster due to no function call is performed.

IMG2OVER(IO, iy, ix, y, x);

Definition at line 234 of file xmipp_image_over.h.

OVER2IMG

#define OVER2IMG	(		IO,
			v,
			u,
			iv,
			iu
	)

Value:

iu = (int) round((((u)-(IO).overumin) * (IO).uistep)); \
    iv = (int) round((((v)-(IO).overvmin) * (IO).vistep));

Speed up pixel index macro

This macro is the same as the function over2img but faster due to no function call is performed.

OVER2IMG(IO, y, x, iy, ix);

Definition at line 196 of file xmipp_image_over.h.

OVER2IMG_Z

#define OVER2IMG_Z	(		IO,
			w,
			iw
	)		iw = (int) round((((w)-(IO).overwmin) * (IO).wistep));

Definition at line 200 of file xmipp_image_over.h.

OVERPIXEL

#define OVERPIXEL	(		IO,
			y,
			x
	)

Value:

IMGPIXEL((IO), \
                                     (int) ROUND(((u) * (IO).uistep)), \
                                     (int) ROUND(((v) * (IO).vistep)))

Speed up pixel access macro

This macro is a speeded up version of the pixel access routines for oversampled images.

OVERPIXEL(IO, 1.34, -0.56) = 1;
