Image Viewer Tool
Description
This tool loads image files and displays them as 2D (x-y coordinate against counts per pixel). The plot can then can be saved, printed, and copied. The plot can also be resized by dragging the corner of the panel.
Supported image formats are png, bmp, gif, or jpg. (There is currently a bug in the tif loader)
How To
- Select 'Image Viewer' under the 'Tool' menu in the menubar.
2. Select a file type from the drop-box at the bottom of the file dialog panel, choose a file of interest, and then click the 'Open' button (see the picture below).
3. If the loading is successful, the image will be displayed. The file name will be shown in the title bar (see the picture below).
4. Some options such as saving, printing, and copying are available from the menubar, or in the context-menu (by right-clicking anywhere in the plot).
5. If the image is taken from a 2D detector, it can be converted into 2D data where the z values are computed as
z = (0.299 x R) + (0.587 x G) + (0.114 x B)
unless the picture file is formatted as 8-bit grey-scale tif.
In the "Convert to Data" dialog, set the parameters relevant to your data and then click the OK button.
