JB2Shape Class Reference
#include <JB2Image.h>
Detailed Description
Shape data structure.A JB2Image# contains an array of JB2Shape# data structures. Each array entry represents an elementary blob of ink such as a character or a segment of line art. Member bits# points to a bilevel image representing the shape pixels. Member parent# is the subscript of the parent shape.

Member Data Documentation
Bilevel image of the shape pixels.
This must be a pointer to a bilevel GBitmap# image. This pointer can also be null. The encoder will just silently discard all blits referring to a shape containing a null bitmap.
Definition at line 230 of file JB2Image.h.
| int JB2Shape::parent |
Subscript of the parent shape.
The parent shape must always be located before the current shape in the shape array. A negative value indicates that this shape has no parent. Any negative values smaller than #-1# further indicates that this shape does not look like a character. This is used to enable a few internal optimizations. This information is saved into the JB2 file, but the actual value of the parent# variable is not.

| long JB2Shape::userdata |
Private user data.
This long word is provided as a convenience for users of the JB2Image data structures. Neither the rendering functions nor the coding functions ever access this value.
