Image data
hi
how to load and view image data with georaster in oracle spatial ?
can you help with the steps involved ?
regards
I'd suggest you start by looking at the GeoRaster documentation:
http://docs.oracle.com/cd/E11882_01/appdev.112/e11827/toc.htm
I'd also suggest checking out GDAL as a way of loading data into GeoRaster:
http://www.gdal.org/frmt_georaster.html
Then come back to this forum when you've got some more specific questions.

Hello i am using TimeMachine to back-up entire Mac image (data + system) on an usb-local drive. I would like (on top of it) add a specific plan to back up some files on a remote network drive. Does TimeMachine support multiple back-up plans ? How ?
Time Machine is capable of backing up to multiple locations, and can be used to back up to both a local hard drive and a networked drive (provided that that drive is in or connected to a Time Capsule or another Mac that is sharing it over the network). The catch, though, is that you can't specify different things to back up to different destinations. Whatever you exclude from Time Machine backups is excluded from ALL backups, and whatever is included is included on all.
So, get a large enough drive that you can back up everything you want in all locations, or use something else for maintaining the network backup.
More information on these topics can be found here:

How can I get the image data from Clipboard with LV
Anybody knows How can get the image data after pressd "print screen button" with LV?
I want to program a software which can save a image as a bmp or jpeg etc, and the image data is from pressed print screen button.
How to get it out from clipboard. I am trapping about. thanks in advance.
Try to make everything AutomaticYou can have a look at Rolf Kalbermatter's post here (give him stars) or, if you're using scripting, you can use the Application class Get Clipboard Image method.

What is the fastest way to record and write image data?
Hello,
I am new to labview and am using the IMAQ software package to record and write data from a CCD camera to the hard drive. The end goal is a program that records and saves as much data as possible as quickly as possible, for experiments lasting on the scale of days. I have been experimenting with the snap, grab, and sequence methods of recording. To save the image data I was told by NI customer support that TDMS streaming would be the fastest method. I have also been experimenting with the TDMS VIs, however I have found the IMAQ Write File 2 VI to be faster in practice. Am I doing something wrong with the TDMS file structure? Is there a more efficient way to convert IMAQ image data to a dataform that can be written as TDMS? I am posting two of my programs to provide a clearer example of what I am trying to do. The first takes a snap of the image and appends it to a TDMS file. The second is the fastest I have found so far and uses Grab to record the images and the IMAQ Write File VI to save them.
Thanks

Camera Capture (Grab) and write image.vi 24 KBHi
For me it is no surprise that the second VI is faster then the first one, the reason is you can not compare this two VI with each other.
In the first VI you work with TDMS files, in the second with png files. That would be much faster, because TDMS files need a lot of diskspace.
Second point, why do you open, write and close for eacht iteration of the for loop a TDMS file in your first VI? That need really a lot of resources, so it coudn´t be fats as well.
Save your converted pictures in one array, an after the acquisition you can save it in one TDMS file. When you need for each picture a TDMS file you have to know that this need some time to do this.
So now for the architecture of your first VI, please look to the LL Sequence.vifrom the examples (C:\Program Files\National Instruments\LabVIEW 8.6\examples\IMAQ\IMAQ Low Level.llb\LL Sequence.vi), there you can see how an acquisition of a number of images have been to do.
When you like it really fast, you make a producer/consumer architecture (see examples in LabVIEW for that).
So in the first whileloop you acquire the images, write into a queue and in the second, parallel whileloop you read the queue and save the images. (see attachment)
Hope that helps
Kind regards

I want to load a picture from the Windows clipboard (and if not possible, then from the Labview clipboard) into actual numerical image data so that it can be processed in lab view. When I'm at the main screen where I can add controls, I see a section of controls called "Vision" in the tool bar where all the different controls can can be added from. When I go to the control called "Image" and put that on my form, and then look at the flowchart/blockdiagram programing window to see what inputs and outputs it has, I only see one output, and no inputs. And when I right click on it, I see NO way to load an image into the Image control. PLEASE help me.
Message Edited by Ben321 on 11-09-2008 04:32 PMHi Ben,
National Instruments has an image processing software called Vision and although I am not completely sure, I think the controls that you found in the control pallet are used in conjunction with the software. Depending on what kind of image processing you want to conduct in LabVIEW, you might want to consider purchasing that product.
If cost is an issue, there are functions in LabVIEW which allows you to take in image files and process them. However, please keep in mind that the capabilities are limited.
Images should be loaded onto LabVIEW not via the clipboard but through loading it from folders or directories. (There might be a way to and so if you find a way please let me know! I would like to know myself =D) If you open the function pallet by right clicking on the block diagram, in the programming folder you should find a directory called "Graphic and Sound". There, you'll find functions in which allows you to process images.
In the "Graphic Type" directory there should be a function called Read JPEG file.vi. There are also others which allows you to read png and bmp files. Please note that there are functions which write as well. Set a file path on the block diagram and inside the "Grahic and Sound" there is a "Picture Function" directory and inside there, there should be a function called "Draw Flattened Pixmap.vi" That changes the image into a format where you can process on LabVIEW. Inside the "Picture Function" directory there are several functions which allows you to process the specified image. Play around with it and see how it goes. And don't forget to Write the file in the end to save any changes.
I hope this helps

How to convert an AVI frame to an image data cluster ?
Hi everybody,
I have previous VIs that manipulate pictures (image data cluster) readen from JPEG files. I'd like to use these VIs to analyse individual frames from an AVI file.
How can I connect the image out of the IMAQ AVI read.vi to the picture input of the Draw Flattened Pixmap.vi?
Thanks for helping,
Olivier
Solved!
Go to Solution.Thanks for the tip but, in my implentation, it generates that the no picture can be manipulated. Could you tell me where is my mistake?

How can I see the entire image date in Metadata EXIF DD/MM/YY?
I cannot see the full image date under metadata EXIF, just the day and month. Could you help me to see the year the picture was taken? Thanks a lot.
Where are you not seeing the full date information? If it is on one of the Browser Metadata Overlays, you may have to increase the size of the thumbnails or remove some of the other data being shown (and/or the metadata labels).
On my Metadata Overlays for Browser, Viewer, and Tooltip, as well as on the Metadata tab of the Inspector, the full date-time stamp is shown, e.g.:

Import from Designer crashes with IMAGE data type
Hello,
I'd like to report an issue with Data Modeler while importing from Oracle Designer. If you consider this a bug, please let me know if I need to do anything else to request a fix for it.
I've used the import > Oracle Designer Model tool to import an application model. The import runs fine for a while, then crashes with a message "There are errors in import - check log file".
The application to be imported has 509 domains, 963 entities to import.
The summary info displayed after the import (when I close the error message pop up) is:
All statements: 1472
Imported statements: 538
Failed statements: 0
Not recognized statements: 934
The log file has the lines below:

I see the issue with the IMAGE data type in the log. The model to be imported does have domains and entities using this data type. The domain actually did get imported, but it shows as "Unknown" logical type, even though there is an Image type available in the Data Modeler type list. None of the entities using IMAGE got imported.
Please let me know if you can provide a fix or workaround for this (other than changing the format in Designer).
Thank you,
Beatriz.Hello Beatriz,
definitely this is a bug. The problem with entities is not IMAGE data type it's supported there (it's overlooked for domains). The problem is volume information - Initial, Maximum, Average, Growth rate. No workaround for that.
Domain can be changed manually if it's just one affected.

Sony Image Data Converter no longer opens RAW files
After upgrading to Snow Leopard Sony Image Data Converter (ver 3.1) cannot open my RAW files. It sees the files but claims they are 0x0 pixels in size. It worked fine with Leopard 10.5.8.
Image Data Converter v2.2.02 also fails to open any files but was OK in 10.5.8. Image Data Lightbox v1.0.02 does run OK, opens a directory of files fine, and converts them. The app crashes on exit every time however!

Can I use Bridge to export image data into a .txt file?

Hello
You may try the following AppleScript script. It will ask you to choose a root folder where to start searching for *.map files and then create a CSV file named "out.csv" on desktop which you may import to Excel.
set f to (choose folder with prompt "Choose the root folder to start searching")'s POSIX path
if f ends with "/" then set f to f's text 1 thru -2
do shell script "/usr/bin/perl -CSDA -w <<'EOF' - " & f's quoted form & " > ~/Desktop/out.csv
use strict;
use open IN => ':crlf';
chdir $ARGV[0] or die qq($!);
local $/ = qq(\\0);
my @ff = map {chomp; $_} qx(find . -type f -iname '*.map' -print0);
local $/ = qq(\\n);
# CSV spec
# - record separator is CRLF
# - field separator is comma
# - every field is quoted
# - text encoding is UTF-8
local $\\ = qq(\\015\\012); # CRLF
local $, = qq(,); # COMMA
# print column header row
my @dd = ('column 1', 'column 2', 'column 3', 'column 4', 'column 5', 'column 6');
print map { s/\"/\"\"/og; qq(\").$_.qq(\"); } @dd;
# print data row per each file
while (@ff) {
my $f = shift @ff; # file path
if ( ! open(IN, '<', $f) ) {
warn qq(Failed to open $f: $!);
next;
$f =~ s%^.*/%%og; # file name
@dd = ('', $f, '', '', '', '');

Using image data read out from a file
Hi,
Having used the GetBitmapFromFileEx(), GetBitmapInfoEx() to acquire the necessary image data (most of them is the .png format), then using the FileToArray() to put the image data in my own binary file, e.g., "mypicture.dat". My idea is that whenever need to use the image, I can read out it from mypicture.dat and then display it on a pcture control. But when loading the image data to the memory, I have no idea to map the image data buffer to an image resource, which can let to acquire a bitmap ID. Because from the cvi's image processing function lists, it seems that must through such as the GetBitmapFromFileEx(), GetBitmapFromFile() to acquire the image data buffer and the bitmap ID, then using SetCtrlBitmap() to diplay it. Is there any way to resolve the problem? Thanks.
DavidWell, to read and write raw data file informations from a PNG image you must adhere to this standard. As a source of informations you may take a look to this Wikipedia page and to the links in this page from the PNG Home site.
So the problem is: does your application worth the effort to study this documentation?
Edit: FYI part of this job has been already made in CVI by Guillaume Dargaud for his ReadSavePNG instrument driver. It's been a long time since I have used this instrument, as I/O operations on PNG files have been integrated into CVI since release 8 and support for JPEG files in release 7 or so. Nevertheless I saw functions in that instrument for accessing raw data in a PNG file so you may find them useful for your needs.
Proud to use LW/CVI from 3.1 on.
