GGD is a cool little tool that helps you view graphical data off of binary encoded files.
Since GGD has a little bit of a learning curve, I decided to give a few pointers on how to use it.
Panel Descriptions
 Main Window
|
This is where all of the data from the binary file will be shown. Kind of self explanitory. |
Information Window |
|
| 1. Data File Name - This is the file that is viewed in the main window. |
| 2. Palette File - This is the file that is used in the palette window. |
3. Image Size - These are the dimensions you want to view your data as.
a. 4,8 are the amount of pixels that the height and width change by.
|
| 4. Screen Size - This is the maximun that your image size can be. |
| 5. Data Endian - Big or Little Endian . |
| 6. Pixel/Bit - how many bits per pixel. |
| 7. Data Shift Mode - How much of the data you skip when searching the file. |
| 8. Data Offset - How many bytes you are from the beginning of the file. |
| 9. Palette/Byte - How many bytes per palette entry. |
| 10. Palette Type - What order the RGB is in. (ex. BGR, GRB, etc.) |
| 11. Extention Bit - For files that use 5R 5G 5B, this is for where the extra bit is. |
| 12. Palette Shift Mode - How much of the data you skip when searching the palette file. |
| 13. Palette Offset - How many bytes you are from the beginning of the palette file. |
| 14. Alpha Test - I really don't know, it doesn't seem to work for me. But I assume it's for the alpha channel. |
|
Palette Window |
This is what the main window will use when it is doing the color lookup. Note: 8 Bit mode only indexes the first 16 palette entries. |
Commands
Main Window
Use these commands when the Main Window is selected.
 or  |
Changes the image width depending on 3a. |
 or  |
Changes the image height depending on 3a. |
|
Changes the width part of 3a. |
|
Changed the height part of 3a. |
|
Changes the Screen Width (AKA max image size). |
|
Changes the Screen Height (AKA max image size). |
|
Toggle Little/Big Endian. |
|
Toggle the bits per pixel. |
|
Toggle the data shift mode. |
|
Toggle the zoom. |
 and  |
Depending on the data shift mode, it will jump a little or a lot. |
|
Palette Window
Use these commands when the Palette Window is selected.
(These commands will not work when the main window is selected)
|
Toggle the bytes per palette entry. |
|

|
Toggle the extention bit. |
|
Toggle the palette shift mode. |
|
Toggle the alpha test. |
and |
