Re: Reminder

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];
        }
}
