Access to Candela/Intensity Data

The results of an intensity calculation can be easily exported from TracePro to another software package such as a spreadsheet or word processor. Do this by making the appropriate candela plot window active and selecting Edit|Copy or pressing Ctrl-C in TracePro. Switch to the other software program, such as Microsoft Excel, and select Edit|Paste or press Ctrl-V. The tabular data is transferred to the other program via the Windows clipboard. The plot image can also be copied as a bitmap via the Edit|Copy Bitmap menu item.

You can also save the underlying data in a text file. First select the desired window to make it the active window, then select File|Save As from the TracePro menu. The Save As dialog box displays to save the file with the default extension txt. The file is saved in tab-delimited format, suitable for importing into a spreadsheet program. Candela plots can be saved in IESNA LM-63-95 standard format (*.ies), the Eulumdat (*.ldt) or Windows Bitmap (*.bmp) formats by selecting the file type in the Save As dialog box.
