| 9 | This tool is to load image files (in the format of png, bmp, gif, jpg, or tif) |
|---|
| 10 | and to display it in the x-y coordinate (against the pixel number). The displayed plot then |
|---|
| 11 | can be saved, printed, and copied. |
|---|
| 12 | The plot can also be resized by dragging the corner of the panel. |

|---|
| 38 | the z values are computed by the Eq. z = 0.299R + 0.587G + 0.114B unless the picture file |
|---|
| 39 | is formatted in an 8 bit Grey-Scale tif. In the "Convert to Data" dialog, users set |
|---|
| 40 | the proper values in the text boxes and then click the OK button to close and to send the data generated to the Data |
