OpenCPicture
OpenCPicture Begin recording a picture definition
#include <Quickdraw.h> Color QuickDraw
OpenCPicParams *newHeader ; a pointer to the header containing the pixel
resolution and the best imaging rectangle
returns PicHandle leading to a variable-length Picture
structure
OpenCPicture performs the same functions as OpenPicture, except that it
creates an extended version 2 format picture, with pixel resolution and the
best imaging rectangle stored in the header. OpenCPicture works on all
Macintosh computers running system 7.0 or later, including machines without
Color QuickDraw.
newHeader describes the rectangle that encloses the drawing information
you supply for the picture and describes the best horizontal and
vertical resolutions for displaying the picture in the rectangle.
See OpenCPicParams for a description of the data type.
Returns: a PicHandle; a handle leading to a variable-length Picture structure
that is allocated and initialized by this call.

Notes: As with OpenPicture, you close the picture using ClosePicture, and
draw it using DrawPicture.
