1.0
===
Changed the mysterious "Calculating text" message to display a WF logo.
No known bugs at time of release.
1.0b2
====
Fixed problem with centering of "Replace OK?" dialog for system 6.
Fixed AE code to dispose of the AE desc after using.
Added boolean for FSSpec support.
Removed/replaced FSSpec calls for compatibility with system 6.
Added ICON for dialogs on systems without color QD.
Shrunk CJPEG and DJPEG dialogs to fit on small MacScreen.
Added "Calculating text..." message in about box (delays were too long on slow Macs).
Fixed bug. User was asked "OK to replace?" if he hit cancel in the CJPEG/DJPEG dialog.
Changed compile notes to move "MacTraps2" into the segment with ANSI.
Corrected a multi-finder (sys6) problem where initial dialog was displayed in back.
Corrected a system 6 problem with the font in the progress window.
Unhighlighted menu bar before processing on Open... and the like.
1.0b1
====
Fixed code to delete zero-k artifact files when an error occurs during conversion.
Dimmed check-boxes in CJPEG and DJPEG dialogs are now gray on a color monitor instead of dithered.
Now set file type before closing file so that finder displays correct icon without having to "Get Info".
Changed standard output dialog to default to the directory that the first dropped file came from.
Updated standard header comments. Added comments throughout the code.
Changed the names of the source files to be consistent with the registered application name.
Fixed a bug that hitting ESC in one of the dialogs would not hit cancel button.
Created a document describing how to build the application.
Added preferences dialog to allow user to change file types and creators, etc. This includes:
Creation of prefs file.
Addition of icon for prefs file.
Support throughout code for prefs file.
Updated progress monitor to save location in prefs file.
Completely re-wrote the About box.
Fixed the dialog centering code for system 6.
No known bugs.
No known deficiencies.
1.0a3
====
Fixed overwriting of existing files. Replaced dialog entry of the file name with a button that calls
standard file. Standard file will check for replacement. If the user does not change the name, an OK
to replace dialog (I stole it from the system) will be displayed (if the file already exists) when the
user hits the OK button.
Added icons and file types for output files. Using the standard 'JPEG' and 'GIFf' types as well as new
files types 'RLE ', 'PPM ', & 'TARG'. The creator is properly set.
Misc balloon help updates: MENUs and Finder.
Interface is 32-bit compatible so the size flags can be set to '58C0' (it always was, but I didn't know it).
Changed error dialog a bit.
Corrected problem with program quitting automatically (after processing) if started by
double-clicking and then a document is dropped.
Fixed program to display intro screen when double-clicked for pre-system 7 machines.
No known bugs.
Known deficiencies:
No method for the user to set file type and creator for output files.
Documentation poor/incomplete (at best) for building application.
1.0a2
====
Completed support for older versions of the system (System 6, 5, ...) [I think]
Fixed memory calculation to use available memory in application heap zone before creating a temp file.
Fixed "nointerleave" to be dimmed in the CJPEG dialog (this was actually a bug in Tom Lane's code. It
appeared as a valid option in his CJPEG as well even though it is not available. He has added a new
#define switch for this. You don't need a new copy of the IJG software since it will be properly
undefined in the version you have.)
Completed balloon help on CJPEG & DJPEG dialogs.
Known bugs:
Program will overwrite an existing output file without warning!
Known deficiencies:
No method for setting file type and creator for output files.
Documentation poor/incomplete (at best for building application).
No balloon help on application icon or on menus.
1.0a1
====
Initial (incomplete/buggy) alpha release
