|
|
* \brief IMage Buffer module.
|
|
*
|
|
* This module offers import/export of several graphical file formats.

|

|

*
|
|
* \section about 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.
|
|
*
|
|
* \section issues 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.
|
|
* - Platform dependency is limited. Some minor patches for
|
|
* amiga and Irix are present. A 'posix-compliance-patch'
|
|
* provides the interface to windows.
|
|
*
|
|
* \section dependencies Dependencies
|
|
*
|
|
* IMB needs:
|
|
* - \ref DNA module
|
|
* The listbase types are used for handling the memory
|
|
* management.
|
|
* - \ref blenlib module
|
|
* blenlib handles guarded memory management in blender-style.
|
|
* BLI_winstuff.h makes a few windows specific behaviors
|
|
* posix-compliant.
