Detailed Description

ImBuf module external interface

This module offers import/export of several graphical file formats.

About the IMB module

External interface of the IMage Buffer module. This module offers import/export of several graphical file formats. It offers the ImBuf type as a common structure to refer to different graphical file formats, and to enable a uniform way of handling them.

Known issues with IMB

• imbuf is written in C.
• Endianness issues are dealt with internally.
• File I/O must be done externally. The module uses FILE*'s to direct input/output.

Dependencies

IMB needs:

• Struct DNA (File Format) module The ListBase types are used for handling the memory management.
• blenlib module blenlib handles guarded memory management in blender-style. BLI_winstuff.h makes a few windows specific behaviors posix-compliant.

Macro Definition Documentation

OPENEXR_HALF

#define OPENEXR_HALF   (1 << 8)

This is the abstraction of an image. ImBuf is the basic type used for all imbuf operations.

Also; add new variables to the end to save pain! #ImBuf::foptions.flag, type specific options. Some formats include compression rations on some bits.
