-
- NOTE: USE OF THESE MODULES REQUIRES ADPRO 2.1.X OR LATER.

- The Loader
-
- THE LOADER REQUIRES "adpro.library" TO BE LOADED IN THE LIBS: DIRECTORY.
- THIS IS PERFORMED BY THE INSTALL PROGRAM
-
- The ADPRO CDXL loader can load most of the image types that the CDXL format
- supports. Specifically it supports 1-8 bit rendered data, HAM and EHB. It
- also supports 8 bit gray and 24 bit color chunky image data. It allows you
- to load (preserve) audio and pad data from existing CDXL files which
- include such information.
-
- The CDXL loader is special in that it stays resident after its first use.
- And, when used from ARexx, it can also keep open the last file used. This
- allows the loader to process animations extremely quickly.
-
- The CDXL Loader main window gives you the number of frames in the CDXL
- file, and the number of bytes per frame of audio and pad data. It allows
- you to select which frame to load.
-
- Along the bottom of the window, "Accept" loads the selected frame. "Quit"
- , closes the file and quits the loader (meaning that the loader will be
- removed from memory). Finally, "Cancel", cancels the load but leaves the
- loader resident and the last used CDXL file open.
-
- If the pre-existing CDXL file contains pad and/or audio data, you can choose
- to load that data or not. If loaded, this information will be saved with
- the frame during the next CDXL save provided that the CDXL file being saved
- has made provisions for audio and pad data of the same size as the source
- CDXL file.
-
- From AREXX, you interface to the CDXL loader in the following way:
-
- The general format of the CDXL loader ARexx interface
- is as follows:
- LOAD "filename" "framenum" n [CMD] [standard ADPRO C_OPTS]
-
- where CMD is 0 or more of the following:
-
- SKIPPAD do not load pad data
-
- SKIPAUDIO do not load audio data
-
- SKIPVIDEO do not load video (audio or pad only)
-
- KEEPOPEN keep the file open. SEE NOTE!!!
-
- CLOSE close the file, and do nothing else
-
- QUIT close the file, and quit (unresident
- the loader), do nothing else
-
- NOPAD do not convert rendered data to 8 bit
- or 24 bit raw
-
- If you do not specify SKIPPAD or SKIPAUDIO, pad and audio will
- be loaded, if present.
-
- NOTE: WHEN YOUR THROUGH WITH A FILE WHICH YOU EXPLICITLY ASKED TO
- ``KEEPOPEN'', YOU MUST REMEMBER TO ISSUE A ``CLOSE'', OR RISK THE
- FILE STILL BEING OPEN WHEN YOU REBOOT WITH POTENTIALLY HAZARDOUS
- RESULTS

- The SAVER
-
- The ADPro CDXL Saver allows you to create, modify and extend CDXL files.
- It allows you to specify the amount of space to leave for audio and
- padding. It, in conjunction with the CDXL loader, can even be used to copy
- audio and pad data from other CDXL files.
-
- The saver may be used with 1-8 bit rendered data, HAM and EHB. It also
- supports 8 bit gray and 24 bit color chunky image data.
-
- The CDXL saver is special in that it stays resident after its first use.
- When used from ARexx, it can keep open the last file used. This allows the
- saver to process animations extremely quickly.
-
- The CDXL Saver main window shows the number of frames (if any) currently in
- the CDXL file, the amount of pad and audio space, and the type of image.
- If you are creating a new CDXL file, you are allowed to enter the amount of
- pad and audio space, and well as the type of image - either raw or
- rendered.
-
- There are two buttons which allow you to select how to handle audio and pad
- space in the file. Each button has 3 settings. "Skip Audio" leaves the
- audio data in the file intact, "Zero Audio" clears the audio space, "Keep
- Audio" saves the audio data that the CDXL loader may have loaded
- previously. The "Keep Audio" selection will not appear unless you have
- loaded Audio data, and it appropriately sized. The other button, with
- values of "Zero Pad", "Skip Pad" and "Keep Pad" serves the same functions
- for pad data.
-
- Below the audio and pad buttons in the Interleaved/Non-Interleaved image
- button (this button is only enabled if you are creating a new CDXL file).
- Beneath this button is the button which allows you to pick rendered or raw
- data.
-
- If you choose interleaved, and you choose rendered data, then the planes of
- rendered data are interleaved in the file.
-
- If you choose interleaved, and you choose raw data, then the format of the
- data is interleaved lines of of the three colors, red green blue.
-
- If you choose non-interleaved, and you choose rendered data, then the
- planes of rendered data are saved one at a time.
-
- If you choose non-interleaved, and you choose raw data, then the format of
- the data is as triples of red,green,blue bytes in a matrix of size
- width*height.
-
- The three buttons along the bottom of the window, "Accept", "Quit",
- "Cancel", respectively saves the selected frame, closes the file and quits
- the saver, cancels the save but leaves the saver resident and the file
- open.
-
- You are allowed to enter a frame number one larger than the number of
- frames in the file, thus extending the file by one frame.
-
-
- From AREXX, you interface to the CDXL saver in the following way:
-
- The general format of the CDXL saver ARexx interface
- is as follows:
- SAVE "filename" TYPE framenum n [CMD]
-
- Where TYPE may be one of
- RAW save "raw" image data
- IMAGE save "rendered" image data
-
- where CMD is 0 or more of the following:
-
- FRAMENUM nn -1 means append, else must be
- 1..#of frames+1 in the file
-
- PADSPACE nn allows you to pick pad space. If not
- creating a file, this number must agree with
- the existing padspace in the file.
-
- You must also specify SAVEPAD for PADSPACE
- to perform its work
-
- AUDIOSPACE nn allows you to pick audio space. If not
- creating a file, this number must agree
- with the existing audiospace in the file
-
- You must also specify SAVEAUDIO for AUDIOSPACE
- to perform its work
-
- SKIPPAD do not save pad data - leave this
- frames pad intact
-
- SAVEPAD save the loaded pad data into
- this frame (sizes must match)
-
- ZEROPAD clear the pad space of this frame to zeros
-
- SKIPAUDIO do not save audio data - leave this
- frames audio intact
-
- SAVEAUDIO save the loaded audio data into this
- frame (sizes must match)
-
- ZEROAUDIO clear the audio space of this frame to zeros
-
- KEEPOPEN keep the file open SEE NOTE!!!
-
- CLOSE close the file and do nothing else
-
- QUIT close the file, and quit (unresident)
- the saver and do nothing else
-
- INTERLEAVED use "interleaved" format. If this
- word is not present then save noninterleaved.
-
- NOTE: WHEN YOUR THROUGH WITH A FILE WHICH YOU EXPLICITLY ASKED TO
- ``KEEPOPEN'', YOU MUST REMEMBER TO ISSUE A ``CLOSE'', OR RISK THE
- FILE STILL BEING OPEN WHEN YOU REBOOT WITH POTENTIALLY HAZARDOUS
