Import a Layer from a Spectral Data Text File
You can import data from spectral data text files
which conform to the format described in the International Glazing
Database: Data Submission Procedure and Reference Manual. (The
manual can be downloaded from the main IGDB page.)
This
file format is an extension of the format used for the spectral data
library in WINDOW 4.1. It is possible to import files from a WINDOW 4.1
spectral data library, but if you are preparing new spectral data files,
they should be in the extended format described in the manual. When you import a file, the program will check to
see if any of the extended information is missing from the file if
it is, you will have a chance to enter the information before saving the
imported layer to the user database.
To import spectral data text files into the user
database:
 |
Choose the menu option
|
|
|
Select the file or files you want to
import
(you can import many files at once using a multiple selection
see Windows help on how to make a multiple selection) |
|
|
Click Open to begin importing |
|
|
If the file is missing any extended
header information, you will see the following message:
'This file is missing some information, it could be a Window4 style
text file. Would you like to fill in the missing information?'
Choose Yes to display the Change
Glazing dialog box, where you can enter the missing data. Consult
the Data Submission Procedure and Reference Manual for
details on how to fill in the fields. The best solution is to
alter your text files to conform to the specifications of the
manual.
If you do not want to
manipulate this layer in Optics and do not want any extra
information to be added to the database, Optics will fill in the
minimum required data for you press OK on the Change
Glazing dialog box, and Optics will describe the changes it has
made. If these changes are acceptable, press OK again to
continue. |
|
|
The imported file will be saved to the
user database.
You cannot save data for a layer with the same filename as another
layer in the IGDB or your current user database. If a conflict is
detected, Optics will ask you to rename the layer before saving it,
or cancel the import. |
|
|
Once the data is saved, the layer can be
used in Optics, or imported
into WINDOW. Make sure you look in the user database to find the
imported data. |
Note:
The dialog box that allows you to select files always opens in the same
directory you can set which directory is opened by default using the
menu option
then setting the location of the 'Default I/O Folder'
Note:
Optics requires some data about the layer in order to allow layer
transformation operations and to allow you to use the layer in a
laminate. You will need to add the extra information to imported data
that does not comply with the Data Submission Procedure and Reference
Manual if you want to perform these operations in Optics. The
best solution is to alter your text files to conform to the
specifications of the manual and re-import them.
