[Bf-committers] Reminder

[Ton Roosendaal]

Hi,

Weird... but i have them here in backup: (check new function name  
conventions!)

void interlace(struct ImBuf *ibuf)
{
	struct ImBuf * tbuf1, * tbuf2;
	extern rectcpy();
	
	if (ibuf == 0) return;
	ibuf->flags &= ~IB_fields;
	
	ibuf->y *= 2;
	
	if (ibuf->rect) {
		/* make copies */
		tbuf1 = allocImBuf(ibuf->x, ibuf->y / 2, 32, IB_rect, 0);
		tbuf2 = allocImBuf(ibuf->x, ibuf->y / 2, 32, IB_rect, 0);
		
		rectop(tbuf1, ibuf, 0, 0, 0, 0, 32767, 32767, rectcpy);
		rectop(tbuf2, ibuf, 0, 0, 0, tbuf2->y, 32767, 32767, rectcpy);

		ibuf->x *= 2;	
		rectop(ibuf, tbuf1, 0, 0, 0, 0, 32767, 32767, rectcpy);
		rectop(ibuf, tbuf2, tbuf2->x, 0, 0, 0, 32767, 32767, rectcpy);
		ibuf->x /= 2;
		
		freeImBuf(tbuf1);
		freeImBuf(tbuf2);
	}
}

void gamwarp(struct ImBuf *ibuf, double gamma)
{
	uchar gam[256];
	int i;
	uchar *rect;

	if (ibuf == 0) return;
	if (ibuf->rect == 0) return;
	if (gamma == 1.0) return;

	gamma = 1.0 / gamma;
	for (i = 255 ; i >= 0 ; i--) gam[i] = (255.0 * pow(i / 255.0 , gamma))  
+ 0.5;

	rect = (uchar *) ibuf->rect;
	for (i = ibuf->x * ibuf->y ; i>0 ; i--){
		rect ++;
		*rect ++ = gam[*rect];
		*rect ++ = gam[*rect];
		*rect ++ = gam[*rect];
	}
}
