## About RHEED Convert
### * What is this?
This program converts RHEED (Reflection High-Energy Electron
Diffraction) patterns into top view of the reciprocal spaces.
This program works with:
CPU: 68020 or higher, PowerPC series
Operating System: Mac OS 7.5 or higher with Thread Manager
This program is a "Fat Binary". It was created using Metrowerks
CodeWarrior Pro with PowerPlant on Power Macintosh 9500/200 and
7600/200 (both Mac OS 8J). It was tested only on 9500/200 (Mac OS 8J),
7600/200 (Mac OS 8J), and 7100/120 (Mac OS 7.5.3J). It may be run on
System 7.1, try at your own risk.

The author makes no warranties. Use the software at your own risk. The
author claims no liability for data loss or any other problems caused
directly or indirectly by the software.
You need enough knowledge for RHEED and its related physics to use the
software. There is no explanation about these physics.
The source codes of this program are also available from the WWW page
of Ichimiya Lab. You can use and/or modify them within private use.
However, you can not distribute modified software and/or source codes
without written permission of copyright holder. You need Metrowerks
CodeWarrior Pro for Macintosh and PowerPlant to use the source codes.
No question about the codes is acceptable.
### * How to use
You will be required to select a PICT file of original RHEED pattern
when you launch the software. Only PICT data is available. Any colored
pictures will be converted into 256 grays.
Document windows are consists of two parts, upper part for original
picture and lower part for converted picture. In the upper part of the
window, there are two circles and a line. Green circle, red circle,
and blue line correspond to specular spot, direct spot, and shadow
edge respectively. You can drag these markers to fit the RHEED pattern
you assigned.
After you fixed positions of markers, you need to adjust camera length
or glancing angle of incident electron. At first, it is recommended
that you find exact camera length from the RHEED pattern with known
glancing angle. The camera length you entered will be stored for next
use.
Push button to start conversion. The conversion can be in background.
If you want to cancel conversion, press button (changed from Convert
button).
When conversion is finished, the result will be appear in the lower
part of the window. You can save the result as a PICT file via Save
menu. You can also Drag&Drop onto the other applications (such as
GraphicsConverter, Finder, etc.) from the result window.
After the conversion, clicking on the original picture with control
key will show you the corresponding point in the result. It also shows
the coordinate (origin is the 00 spot) in the status area beside the
progress bar.
You can also Drag&Drop onto the upper part of the window to place the
original picture from the other software.
### * Options
Below is the explanation of items which can be changed in the options
dialog (in the File menu).

Vertical Scale: Enlargement scale of results (integer from 1 to 10).
Miscellaneous
Specular Spot, Direct Spot, Shadow Edge: You can change the marker
colors. Click on the colored pane.
Save PICT as
Creator Field: Enter creator code of PICT files. The left shows the
document icon. You can choose an application or a document by clicking
on the button. You can also Drag&Drop an application or a document
icon onto this field from Finder.
Buttons
Revert to Default: Revert all settings to the factory ones.
