ΓòÉΓòÉΓòÉ 1. About MMBrowse ΓòÉΓòÉΓòÉ
The MMBrowse application is a Presentation Manager application which
demonstrates the use of the Multimedia I/O subsystem (MMIO). For more detail
information about MMIO, please consult IBM Multimedia Presentation Manager/2
Programming Reference.
ΓòÉΓòÉΓòÉ 2. Get FOURCC ΓòÉΓòÉΓòÉ
Every installed MMIO I/O Procedure must have a four character code (FOURCC)
associated with it. It must be at most four characters long. For example, the
OS/2 1.3 Bitmap IO Proc's FOURCC is OS13. If you are unsure of what the FOURCC
should be, please contact the author of the IO Proc you are trying to
install/remove.
ΓòÉΓòÉΓòÉ 3. Open an image file ΓòÉΓòÉΓòÉ
Use this choice to open an image file for viewing.
ΓòÉΓòÉΓòÉ 4. Save an image file ΓòÉΓòÉΓòÉ
Use this choice to save an image file. The file format of the image depends on
the image file extension, and the default one is OS/2 2.0 bitmap.
ΓòÉΓòÉΓòÉ 5. Install an I/O procedure ΓòÉΓòÉΓòÉ
Use this choice to install a multimedia I/O procedure. For more detail
information about MMIO, please consult IBM Multimedia Presentation Manager/2
Programming Reference. The default file extension for IOProc is DLL, and this
sample program requires entry point to an installed IOPROC to be
"IOProc_Entry".
ΓòÉΓòÉΓòÉ 6. Remove Permanent I/O Procedure(s) ΓòÉΓòÉΓòÉ
Click on any permanently installed I/O procedure(s) you wish to remove from the
INI file. After you're done, press OK to remove. You must exit the MMBrowse
application to have the removal of I/O procedures take effect. Since this
sample program requires an entry point to an installed IOPROC to be
"IOProc_Entry", the listed installed I/O procedures that can be removed are
those that can be reinstalled.
ΓòÉΓòÉΓòÉ 7. Query installed I/O Procedures ΓòÉΓòÉΓòÉ
