How to compress images to video?

Hi All,
I generate 15 images every second, and I want to make it into a video
stream and send it to someone else through network.
To elaborate: I have a Frame window and I want to show the other person
what is happening on the window. So I capure image of window 15 times
in a second and want to convert to video stream, send to other person, and the
want the other person to view the video.
Can someone give me an idea how can I achieve this..
Thanks,

PS: There is "video compression manager" in windows API to compress image
data for use in an AVI file
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_video_compression_manager.asp)
Is there something similar in java?

I don't know what is an API key.
However in the context of visual Net you can create very simple a thumbnail.
Be aware this method seems to be to extract a thumbnail. But it is not, it simply creates one.

How to compress image files, jpeg, bmp, gif, png, tiff, etc

I am new to Jave imaging, does anybody know how to compress an image file, including jpeg, bmp, gif, png, tiff format.
Thanks
JC

some are already compressed.
If you just want generic compression, it doesn't really matter what type of file they are. A simple approach would be to use ZipOutputStream

How do I create auto run from one slideshow to another in idvd?

Hi! It is my 1st time using iDVD. I've created 6 buttons with each button for 1 set of slideshow. Every time 1 slideshow finishes, it goes back to the main menu and I have to select the next button to play the next set of slideshow. How can I set it to have all the slideshows automatically played sequentially? Other words, can I have a PLAY ALL button on top of all the 6 buttons?
Thank you.

... When I burnt my idvd slideshow project to a dvd on best performance, the image quality is really bad. It has lost all his sharpness and it just looks blur.
You'll need to understand that pictures and video are not the same thing and if you convert on to the other you will loose quality. What you are doing is taking a still image that consists of millions of pixels and putting it into a 720x480 frame that consists of two interlaced fields.
If you are not happy with the quality you can try software like Photo to Movie or Fotomagico. Both seem to do a good job creating video from stills.

My TV is a HD flat screen.
And that is about four times bigger than the SD DVD you created. Already the process of going from stills to video is not easy and enlarging a compressed image is only going to make it worse. If you want to play on an HDTV you'll need either to create a Blu-Ray disc or get a player with outstanding upscaling qualities.

How to create transparent image at run-time?

How to create transparent image at run-time? I mean I want to create a (new) transparent image1, then show other (loaded) transparent image2 to image1, then show image1 to a DC. The problem is - image1 has non-transparent background...

i'm not sure, but you can set the alpha value to 0 in all pixels which are 'in' the background..

How to show a compressed image in the report?

Hi
I have created a new report.what i do in application is i compress the image and save it in database.now i need to retrieve the compressed image and display in the report. I have used the following code to decompress the binary data save in the image.I
dont know after that what should i do. Please help me to show the picture in SSRS Report. I need to show picture in many reports.one of my doubt is how to call this function in SSRS Report. The function accepts input as byte but in database the column in varbinary.
should i convert the input type of function to varbinary instead of byte array? Please help me.
Public Function Decompress(ByVal arr As Byte()) As Byte()
Dim notCompressed As Boolean
notCompressed = False
Dim MS As MemoryStream
MS = New MemoryStream()
MS.Write(arr, 0, arr.Length)
MS.Position = 0
Dim stream As GZipStream
stream = New GZipStream(MS, CompressionMode.Decompress)
Dim temp As MemoryStream
temp = New MemoryStream()
Dim buffer As Byte() = New Byte(4096) {}
While (True)
Try
Dim read As Integer
read = stream.Read(buffer, 0, buffer.Length)
If (read <= 0) Then
Exit While
Else
temp.Write(buffer, 0, buffer.Length)
End If
Catch ex As Exception
notCompressed = True
Exit While
End Try
End While
If (notCompressed = True) Then
stream.Close()
Return temp.ToArray()
Else
Return temp.ToArray()
End If

Thanks & Regards Manoj

Please try this
Public Function Decompress(ByVal arr As Byte()) As Byte()
Dim s As Byte()
Dim notCompressed As Boolean
notCompressed = False
Dim MS As System.IO.MemoryStream
MS = New System.IO.MemoryStream()
MS.Write(arr, 0, arr.Length)
MS.Position = 0
Dim stream As System.IO.Compression.GZipStream
stream = New System.IO.Compression.GZipStream(MS, System.IO.Compression.CompressionMode.Decompress)

How to auto rotate Images on Full Screen Slideshow if pictures were taken mixed Portrait and Landsca

In Muse: How to auto rotate Images on Full Screen Slideshow if pictures were taken mixed Portrait and Landscape

There is no way that Muse would automatically rotate the images. What you can instruct Muse to do is whether you want to show all image content and leave blank space in either direction OR scale the image to fill the frame resulting in some cropping, but filling the otherwise blank space.
The options are Fit Content Proportionally and Fill Frame Proportionally respectively.

How do you run a slideshow with no music in new Photos app

In the new Photos app I can find no way of running a slideshow without music - either the standard themes or selecting my own music. How can I run a slideshow with no music at all? No setting, tab or option seems to be available to achieve this.

Hit top right arrow for slide show; click on Music, click button next to search; choose Theme songs, click on blue check mark to remove it, then hit PLAY SLIDESHOW.

How do you configure a VM image to run a custom script ONCE on startup?

Hello,
I am creating a Windows image that will be deployed to the VM depot:
https://vmdepot.msopentech.com/List/Index
When the image is run for the first time, I'd like to run a custom script. However, I only want this script to run the first time the VM is run (and never again).
How would I do this?
Thanks!

How to compress non-image object streams using maximum compression in acrobat x pro

Please provide the screenshot if possible. Thanks!

ZIP is the best compression for non-image streams, and it will almost certainly already have been used.

How does the TIFF format compress images?

When we choose "File> Save As" to save an image to a TIFF file, a TIFF Options dialogue box appears with 4 image compression options( None, LZW, Zip, Jpeg). What is this for? Does the TIFF format compress images? Are they destructive to the image quality? THANK YOU

If you select no compression, it will take up too much space, guaranteed. TIFF lets you pick any compression method supported by your program and the viewing program. Some are lossy, some are lossless. Most TIFFs tend to be compressed in LZW or ZIP, both of which are lossless. You can also choose to compress your TIFF using JPEG compression, which is lossy, but I can't imagine why you would do this instead of simply saving as a JPEG file, which is more likely to be properly opened in browsers than a JPEG-compressed TIFF file.
And in response to one of the previous posts, not all compression throws away details from your file. Only lossy compression (e.g., JPEG, or in the music area MP3) throws away data. The lossless compression techniques simply encode the data in fewer bits if possible. (One important fact not relevant to the web, where you will use 8-bit-per-channel files: If your photos are 16-bit-per-channel, don't save in LZW compressed format; they will actually become larger than the uncompressed image.) For a simplified example, if there is a series of 16 pixels of solid white, a losslessly compressed image will have code that says, in effect, 16 pixels of (255,255,255) using an abbreviated code instead of simply listing (255,255,255) sixteen times. It builds up a directory of byte combinations and can use just a few bytes to refer to many bytes of image data. Because the coding and decoding is exact, there is no change in the image data when it's opened.
JPEG is a lossy compression technique that doesn't actually record pixel values at all. It uses formulas to specify averages and changes within regions. In effect, it records the fact that a given group of pixels has values centered on X color, and that the upper left is much pinker and the lower right is much greener than the average. When you pick the degree of quality for JPEG compression, you tell it how small to make the comparison cells. As you can imagine, if the image has text, tree branches, or other highly contrasty subject matter, this will cause serious weirdness if the comparison cells aren't very small (i.e., you don't have the quality set to max).

How does the quality of Previews effect slideshow performance?

Does anybody know how Aperture uses the Image Previews in a slideshow? The default image preview is half size and medium quality. Does this mean Aperture has to generate full size previews on-the-fly during the show?
If I changed to full-size previews at high quality am I helping Aperture display the images during a slidshow, or not?
Maybe Aperture doesn't use the previews at all during a slideshow and making a few hundred full-size previews would only be filling up my hard drive for no useful purpose.

And another quote from the fine manual:
Re Slideshow:
Rendering Preview Images
Aperture renders preview images in four situations:
When a library is upgraded—provided that the “Create previews for existing images” checkbox is selected in the Welcome to Aperture dialog
When an image is imported, or a version is created, rotated, or adjusted—provided that the Maintain Previews item is selected in the Library Action pop-up menu (with a gear icon)
When you Control-click the library, a project, or an image selection and choose Update Previews from the shortcut menu
Immediately before a slideshow, if the previews are not up to date, and the slideshow preset uses the Best quality setting
When rendering a group of preview images, Aperture uses the current application preference settings for compression quality and picture size, not the settings that were specified when preview rendering began. For example, if you have the quality set to 6, and then halfway through rendering you change the setting to 8, the previews that have not yet been rendered will be compressed at setting 8. Previously rendered previews are unaffected.
So, a high quality slideshow will require high quality previews, and indeed Aperture will render previews before rendering a slideshow, if the preview quality is not sufficient.
Regards
Léonie
