Q: I opened a sequence for export as an AVI file but when I tried to save the file I got an error message like "The selected filter is not able to save this object". What is wrong?
A: When you tried to save/export the sequence you selected the view of a frame of the sequence. Vision interprets this as if you wanted to save that special frame of the sequence as a single image which is incompatible with the AVI format. Switch to the workspace and select the sequence you want to export. That should solve the problem.
Q: I tried to export an image that showed intensities as different colors as TIFF file but only in grayscale when I opened it with another program.
A: Images aquired with the IMAGO camera support 4096 gray levels and any colors are due to false coloring using the display palettes. To export an image with colors it is therefore necessary to run the FullColorMap macro which converts the image to a color image.
Q:: I need to get data out of Vision for further analysis and documentation. But other programs seem to be unable to read the TIFF format!
A:
In Microsoft's definition, a 16-bit image is a color image with
5 bits for each band (red, green and blue). A one channel 16-bit
bitmap format is not defined.
The 16-bit TIFF format is not very common, so standard applications
like Microsoft Word don't support it properly. But if you have another
professional image processing application (e.g. Optimas, Matrox
Inspector, ...) which supports 16-bit TIFF, you should be able to
exchange image data via TIFF.
There are also some free programs available over the Internet (e.g.
UTHSCSA ImageTool at http://ddsdx.uthscsa.edu/
or OSIRIS32 at www.expasy.org,
which support 16 bit TIFF. TIFF is
a very flexible data format. As a result there are many programs
that claim to be able to read TIFF, but virtually none of them supports
all valid TIFF variations. If you use a program which claims to
be able to read and write 16-bit TIFF, but which can not read Vision's
TIFF, please e-mail
us a sample 16-bit TIFF file from this program.
Vision supports the standard way of data exchange via Clipboard
(Edit/Copy and Edit/Paste). By using Edit/Copy on an image window,
you'll get an 8-bit image which looks like the displayed one.
To export a whole sequence mark it in the workspace view and use
File/Save as... Alternatively, use the Macro Export.bas provided
in the Samples directory.
Q: I would like to export image sequences in Quicktime format but I did not find this format in the file export dialog.
A:
You can install Quicktime export using the qtime patch found in Support/Downloads qtime.zip.
Note: in order to work, Quicktime has to be installed on the machine where TILLvisION runs.
Q: I am not satisfied with the kinetic display in TILLvisION and would like to export the data. How can I do this?
A: Since most of our customers use specialized software for numerical data analysis and scientific graphing we decided to concentrate on the imaging-related features. Export of data can be carried out through several methods like saving as text files, copy and paste via the clipboard, or by using more flexible macros like OLExcel, GridExpo or IGORExport.
