SuperHiRes Convert                              Written by Jason Harper

This program will convert a variety of picture file types to Apple IIgs SHR
format.  To use, you must first select the type of file you wish to convert from
the list on the screen.  If you are converting Apple HiRes or Double HiRes, you
also choose whether you want the resulting picture in full color or not.  You
then select 'Load...' from the File menu and choose the file to be converted.

Only files that seem to be of the selected type will be displayed. Clicking on
'Open' will load the file and convert it.  You will see the conversion on the
screen: press any key or the mouse button to continue.  There will now be a
scrollable view window on your screen.  The colors used in this window will be
standard ones rather than the actual colors from the picture: this allows you to
examine a picture with a damaged color map, for example.  If you want to see the
picture in its true colors again, select 'Full screen SHR' from the View menu.

If you are satisfied with the conversion you can save it to disk with the 'Save
SHR' option on the File menu.  Or you might want to try a different file, or the
same file with a different setting of the Full Color option.  Select 'Quit' from
the File menu when you are done with the program.

There are a few bugs left in this version that I haven't managed to exterminate
yet.  If anybody has any ideas about how to fix them, please let me know!

1. The 'Select filetype' window is a modeless dialog, and as such is handled
completely by _DialogSelect.  However, it is sometimes redrawn with all items
in a dimmed state.  It is only drawn correctly when it becomes the frontmost
window.

2. The help window that you are looking at now does not call for a grow box in
its definition.  However, as you can see, there is one!  It is functional, but
the minimum window height is calculated as if though it wasn't there.  Try
reducing this window to minimum size:  the up/down arrows will overlap, and the
thumb box will have a negative height.

3. There is an occasional crash when zooming the view window after using the
View Full screen command.  I have traced the problem down as follows:
TaskMaster calls ZoomWindow, which calls GrowSize, which calls CharBounds,
which crashes because the QDGrafProcs StdTxBnds pointer has been trashed.  I
have no idea why.

This program is public domain, and I would like to see it widely distributed.
However, you might want to wait for the final, debugged version before
spreading it around too far.  Also, if you know of any other picture file
formats that could be converted to IIgs use, please send me format details and
a source of downloadable samples and I'll try to include it in the next version.
