How capture image at 800600 from videocapture at 640480??

the device can capture image at 1600*1200 max, but videocapture is only at 640 * 480.
Im using JMF.
Thanks.

Have u checked your refresh rates (you can set refresh rates from the drivers - for games (older drivers had this feature only for OpenGL, now they have it for D3D as well) -> in the advanced section). I'm not sure that this is the problem, but it' worth giving it a try.

How capture image to max. resolution??

Im using JMF and my videocapture frame is running at 320*240.
It`s possible capture images at 800*600, 1600*1200....... of resolution??
Only its possible capture at resolution of my livevideo JFrame?
Please i need help!!!!

Hello,
I am able to capture images using JMF. I wrote a applet (signed) that would capture an image and save it to a folder in server.
The image is being captured with dimensions 640x480. But at the client side, they are using a webcam to capture images. I am not sure whether with that webcam, the image, when captured still gets saved with the same resolution.
How can I programatically specify to save/capture the image in a pre-defined resolution i.e. 640x480. So that whichever device is used at client side, the image still has a universal dimension.You can't guarantee that, you can only capture in whatever format the web cam will allow. If the camera doesn't support 640x480, then you're not going to be able to capture in that.
I did search the forum but have not found any significant help. Could anyone please throw some light on this?The search features of the forum are pretty poor, but if you'd searched for "changing resolution of webcam", you'd have come across...
[http://forums.sun.com/thread.jspa?forumID=28&threadID=5365494]
There is sample code for changing the resolution of a capture device... you'll have to get as close to 640x480 as you can, and then probably scale the image using Java2D stuff beyond that to guarantee the image is the correct size.

So, please let me know step by step how can I perform this using the Lightroom software. Also I wan to know what should be the aspect ratio to do so.Thank you in advance

The aspect ratio should be set to 200x280, or equivalently 5x7.
I don't think it is possible to do the cropping automatically in Lightroom, you'd have to do this image by image to crop the faces correctly.

Capture image and get info from flv file

Hi everyone
would apprichate help from any one who can tell me how and is
their any batch software for win\linux that can prepare xml file
with movie length and jpg\gif image capture of one of the frames
(if i can set to to frame 20 and not 1 as dafualt) out of flv file.
its for academic fms project and we have thousands of courses
which we recorded and got them on flv, and need the data for the
catalog.
so - if any one can pls assist, got something ready or just
tell me how to do it, we really will apprichate it.
10x very much !

FLVMDI will create the XML file for you (it will have
additional nodes, but it will have the info you need). FFMPEG will
extract the images for you.
I'm not sure if either of those programs do batch
runs.

How do I change picture resolution from screen capture?

If I want to take the image on the screen in Encore CS5 and save it as a photoshop picture the resolution is 70 DPI. Is there any way to change this resolution? I would like sharper pictures if possible, 100 DPI to 200 DPI if this can be done.

Core 4 2.4 ghz processor
6 GB Ram
700 GB free on hard drive
Windows 7 64 bit

I completely agree with your goal - getting as a good a resolution print as possible. But your focus on dpi for the capture of a frame will not help you.
Kind of like scanning an image. If you are going to blow it up later you want to scan at higher resolutions than if you don't. There is of course image quality versus file size issues, etc. etc. but at least I would have the option to change resolutions on capture.
Scanning at a higher resolution adds more pixels. So, for example, scanning a finely detailed 7.2 x 4.8 inch image at 300 dpi produces 2160 x 1440 pixels. Scan a grainy photograph similarly, and it will be 2160 x 1440 and look lousy. Use a 5 megapixel camera to shoot the original scene, you've got more pixels. If you have only the SD video image, all you have is the 720 x 480 pixel image. It doesn't matter how you set the dpi on capture, just that you capture all 720 x 480 pixels.
In Premier Pro CS5 and Encore CS5 the image size is 10 inches by 6.667 inches and the resolution is 72 pixels/inch.
Pulling from womble the image size is 7.2 inches by 4.8 inches and the resolution is 100 pixels/inch.
The part you are not listing is the fact that for each of those the pixel size is 720x480. As long as you capture the 720 x 480, the resolution of the image is not improved by flagging it as 72 dpi or 100 dpi. You can change that in photoshop for either of those captures, and you get a different print size, but no more or less pixels.
In either case, re-sizing the image in photoshop doesn't change the pixels/inch resolution. I want to capture the original image in as good resolution as possible rather than having to correct it after capture.
"As good resolution as possible" is 720 x 480.

Capturing images from camera and uploading to sharepoint library automatically.

Hello Everyone,
My requirement is to capturing images from camera and uploading to sharepoint library automatically. No manual uploading will take place.
Please suggest me.
Thanks,
Rajesh

Hi,
From your description, my understanding is that you want to capturing images from camera and uploading to sharepoint library automatically automatically upload images to SharePoint library.
You will save images in your local computer after capturing visitors’ image. You could develop a custom timer job to periodically get pictures from the local folder in your computer. Please refer to this article:
Create and Deploy Custom Timer Job Definition in SharePoint Programatically
http://www.codeproject.com/Tips/634208/Create-and-Deploy-Custom-Timer-Job-Definition-in-S
you could upload pictures to your SharePoint from the folder with C# code, please refer to this article:
How to: Upload a File to a SharePoint Site from a Local Folder
https://msdn.microsoft.com/en-us/library/office/ms454491%28v=office.14%29.aspx?f=255&MSPPError=-2147217396

Capturing image from Webcam

Hi,
Is there any way in which Java can be used to capture images from the webcam and save it to a predefined image file name?
Any examples out there?
Alternatively, I could have the application written in other languages, but still, I would need my main Java app to launch this external app.
Thanks alot.

Hi,
Is there any way in which Java can be used to capture
images from the webcam and save it to a predefined
image file name?
Any examples out there?
Alternatively, I could have the application written in
other languages, but still, I would need my main Java
app to launch this external app.
Thanks alot.Yes, the ExampleSave from the JavaTwain package at http://www.gnome.sk does this job :)
If you just want to see how Java Twain works with your webcam (works with a scanner too):
- java (1.2 or higher for Windows, 1.3 or higher for Mac OS X) has to be installed on your computer
- a scanner or camera has to be installed on your computer
- download the trial package from http://www.gnome.sk
- unzipp it
- go to the examples directory of the unzipped package
- in Windows: doubleclick the runExampleShow.bat
- in MacOS:
- open the Terminal window
- change the working directory to the examples
- run .sh file (type ExampleShow.sh or sh ExampleShow.sh)
This will pop up the Twain Source Selection user interface. There, all your scanners and cameras which do have a twain driver should be listed. (About 90% of scanners and cameras on the market do have a twain driver for Windows, only a few do have a twain driver for MacOS.) Select one of them. The user interface of the selected scanner (camera) will appear. Confirm the scanning (you can set the scanning parameters first). The scanned image will be displayed in a separate window. To end the application, close that window.
Running different examples, you can test scanning with hidden UI, saving the scanned image, using ADF, ...
If there is any problem, do not hesitate to inquire about it at the technical support, email: [email protected] . I am the member of the staff :)

Capture image from isight

What is the best way to capture images from iSight using Applescript ?

erritikamathur wrote:
What is the best way to capture images from iSight using Applescript
(1) Depending on what you want to do, you may be able to use your "Automator" application to make your scripts instead (Automator calls them "workflows".)
When you launch Automator, you can immediately select the "Photos & Images" as a starting point to see if it will meet your needs by selecting "my Computer's Camera" in the "Get content from:" choices bar there.
For more info on Automator, start with Mac 101: Automator and then launch Automator on your Mac and use its Automator > Help as needed.
(2) If you really need to use AppleScript, you need to understand that you script applications (such as iChat), not devices (like iSight.) Therefore, first decide what you want to do with your iSight. Click -> here to see a list of some applications that can operate your iSight.
Once you have decided what you want to do, launch your Mac's AppleScript Script Editor.
Next, open Script Editor's Library window to see a list of Apple apps that are scriptable. Those that can control iSight include iChat, iMovie, and iPhoto. Double-click on one of the apps of interest to see the dictionary of functions that can be scripted in that application. Reviewing the library for any app will help you determine whether the functions you want to control can be scripted in that app. If not, you need to find another app that can control that function, develop an alternate process flow that can be scripted, or look for a way to accomplish your task other than with AppleScript.
Some third party apps may also be scriptable. See the documentation or support info for particulars directly from the developers of those apps.
More help is available from a variety of sources. For instance, you can check your Mac's Help on specific applications to see if they contain info on automating them. One specific example is iChat > Help, which gives a good start on your iChat study.
Unless you already know how to use AppleScript, you may also need to do some more general study or perhaps take advantage of the Apple training series book available from the Apple Store.

How can I make different catalogs from the same image

How can I make different catalogs from the same image where that image has been changed in some way between the catalogs. For instance if I wanted to have a catalogs for cropped images and have 3 catalogs one for 4x6 , 5x7 and 8x10 cropping. When I tried this , if I changed a file in one catalog that same image in the other would change also.

Do not confuse the creation of the crops and the display in collections per crop ratio.
Of course one virtual copy (VC) per crop ratio is needed. If the same image should be cropped in all 3 mentioned ratios there would be 3 VCs.
The OP asked how to have/see a set of same-crop-ratios.
After having created the virtual copies for whatever crop ratio he wants, the way to display this result in the fashion asked for is via smart collections, provided they can be found. Without a plugin the naming of the VC with the crop ratio applied is a straight way to achieve that.
IF the wish is to get new crops automatically added. (See my answers 2+3)
IF the wish is to creat static collections per crop ratio for a certain set of images, I'd go as follows:
1. Select all images you want to have cropped in that way,.
2. With this selection click on the + to add another collection and fill the dialog box like this:
Then navigate into this newly created selection and perform the 4x6 crop - according to taste individually or by synchronizing the first crop.

Capture images (JPEG) from IP-Camera

Hey there!
I have been trying to capture images from an IP-Camera. I understand that this has to be done by using a custom DataSource and I have tried many many example found here on the net, but with no results.
I think I've tried every piece of code found here at this forum regarding this subject.. :/
The best I could do was not getting an error while creating a custom DataSource from a BufferedStream..but the when I try to configure/realize the Processor - created with Manager.createProcessor(customdatasource) - it gives me an error which, I think, has something to do with unrecognized content..
I could post all the examples I tried but I think it would be too much of a confusion so...does anyone have a full working example of code to achieve this? WITH the frame grabber class? plizzzzzzzzz?
Thanks,
Edd

How to create a pdf file from multiple images ?

Dear All,
I want to create a SINGLE page pdf file from two or more page size images that are combined to make a single page pdf. Again, this question is on pdfs that are made out of several, atleast two color images and a black-and-white mask for one of them.
I have such pdf files from an unknown source (the producer is edited out) whereby there are three tiff images, obtained using the well known pdfimages extractor.
When I want to make a pdf out of tiff or png or other image formats, I right click and tell Adobe Acrobat to make a pdf.
However, I dont know how I can give a command to select say, three tif images and specify which is the mask for which and then join them in a way that I get the pdf from the composite of the two color images and a mask for one of them.
Please help me out.
I am a little familiar with the pdf structure skeleton and when necessary, fixed xref tables in one of my favorite editors. A few years ago, I also wrote a bunch of javascripts to make some annotations and needed some automation and used some itext type libraries. However, I need your help in this problem as I am now rusty and forgot some of what I studied to solve my earlier problems. This is a new problem for me. Gentle hints from you would be very nice to help me in this problem. Please specify if necessary what manual and pages to read. in the pdfspec.
Best Regards

I would gladly mention that I am working on windows platform, preferably XP.
I can also work on linux for free products that come with it.

But adding other products, for the help of an adobe products user,
even if it outside adobe, shall add greater prestige to your company
and give impression of user-centeredness.

Well, just add the few pdf stanzas since you are proficient on it and
I am presently a little rusty as I mentioned. Just asking a little
extra yard, not even to go an extra mile.

Well, ascii format or uncompressed format that is human readable. I
know its a binary file, but human readable ascii version of it.
I hope you can give me some stanza and various other approaches
possible so I can select or combine things for myself. I see only a
miniscule number of posts claiming to have written masks in this forum
and then with no details.

How do I move a picture from camera raw to photoshop? When I click open image I get a checker board

How do I move a picture from editing in camera raw to photoshop? When I click "open image" I get a checker board in photochop

Sindbad. A suggestion, to let us know all the specifics of your machine: go the the help menu, and select System Info...
Copy the contents, and paste it in an answer there.
You might want to remove your serial number.
Thanks to that we will know: the exact version of Photoshop, your memory, where Photoshop is installed, the graphic card and its drivers, and also if you are using third party plug-ins.
Some other users reported that when launching Photoshop holding down the shift key (this disables the plug-ins), he was able to see the images.
The solution in that case is to search for updated plug-ins (or to report the plug-in manufacturers that their plug-ins causes issues in Photoshop.
