Hi Harold,
Things are hooked up wrong....
(Also, you don't really want to read the same file with each repeat. Once is enough! )

How can I Manually Insert an Image into a Picture Control?

Hi,
I am able to insert an image programmatically into a picture control. But I want to insert an image into the picture control without any code that is manually. How can I Do that?

You may also drag and drop a picture directly to your front panel. You can also use paint, or some other tools, to copy a part of a picture and past it into your front panel. This actually works for the block diagram also. Se example
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

Scaling JPEGs to fit into picture control

Hallo NG,
I have a frontpanel with a fixed sized picture-control where I want to
display a JPEG-Image.
I use the ReadJPEG and DrawFlattenedPixmap to display. Now, if my JPEG is of
bigger size than my picture control, the rest of the image gets clipped.
How can I scale a JPEG image to fit it into the control. If the control and
the image have different aspect ratios, that's OK, I could scale it down
with fixed ratio, and leave parts of the control blank.
So again: How can I scale the images, is it possible with those two VIs
mentioned above or do I have to make it more low-level and complex ?
Oliver

A solution I prefer to use involves .NET and a GDI Resize, this method supports many file formats, and bit depths, and seems pretty quick when .NET can be used.

I used it in my quick drop show VIs, to scale VI icons to fill the window size.

PDA example: Reading a jpeg file into a picture control

Hi
Does anybody have a simple PDA example of how to read a .jpg file and show it in a picture control. The jpg examples I've found does not compile for PDA.

The hard way would be to write your own JPEG -> Bitmap / Array
de-compression routine. You will probably find example (C++) code at
the JPEG web site.

How limit the movement of the slider within the picture?

Hi Guys,
I have a before/after slider but divider is moving outside the image. How can i fix this - stop the slider near right and left border of the image?
Any ideas?
Many thanks!

I'm nor sure what you used to zip your files..
I can open WinRAR files and regular zip files on my pc but when I try to download your file it does not look like what you show in pic.

How to get a jpeg image to a movie with best possible quality

I've got a jpeg image from my 2 megapixel digital camera and I'm playing around with converting it to a movie. Yes, its a one image movie.
+QuickTime Pro+ does a superb job when I choose H.264, 1024 kb/s, but I can't get iMovie 5.0.2 to give me the same quality. This is what I have done:
1. Create a new movie as type MPEG-4.
2. Imported the jpeg image and adjust the time from 5 seconds to about 2 seconds.
3. Select Share, choose H.264, 1024 kb/s from the relevant option and after the movie making happens, the quality is obviously inferior to that from +QT Pro+.
*QUES 1*: Why is the quality inferior?
I have been to iMovie help and noticed this comment:
"When you import clips in a format different from your project, they are converted to the video format of your movie."
*QUES 2*: Is this why my jpeg image is losing quality? Is iMovie converting it to something else?
Further, when the jpeg image is first imported, it is assigned a clip time of 5 seconds. When I move one of the sliders to reduce the time to just a few seconds, I notice that a black band appears at the top of the image in the iMovie window and as I make the time smaller, the image zooms in and the black band becomes wider. Letterboxing at the top seems to be occuring. This I can't fathom.
*QUES 3*: Why does iMovie zoom in when I adjust time?
Any comments most appreciated, especially those that tell me if iMovie can make a movie from jpeg images with the same quality as QT Pro -- and how to do that.

Re the quality -- I think I have answered this one myself. Correct me if I'm wrong, but it seems to me that when I select a video option (DV, HD 1080 and so on), iMovie sets up a frame size to suit, and the frame size that iMovie sets up for MPEG-4 happens to be 640 x 480, thus the poor quality of my jpegs when I selected that option. The poor quality had nothing to do with the MPEG-4 format.
Now the interesting things is, MPEG-4 is not limited to 640 x 480. It can be any size. So my question is:
Ques: Can I set up a movie within iMovie that is any size I want? QT Pro gave better results because it allows any size movie at all, and thus adjusted the movie size to my jpeg size (1800 x 1200 pixels) when I imported an image from my digital camera.
As it stands, not even the highest quality option in +iMovie 5.0.2+ (HD 1080) can handle the images from my piddly-little 2 megapixel camera.

How do I get picture control to display PNG images with transparent background?

I have an image of a robot arm looking from the top with a transparent background and saved as PNG. When I drag the image directly to LabVIEW front panel, the image shows properly with the transparent background, but I want to manipulate it such as rotate the image. I used the Read from PNG.vi to read the image to a picture control, but the background isn't transparent anymore. Am I missing something?
Please help.

unclebump gets 5 stars for referring you to a document that I wrote.
Incidentally, I wrote it years back, for LabVIEW 7.0. A couple of notes to summarize:
The picture control doesn't "really" support transparency. However, the image data type supports masking, and stores the alpha channel, if present in your image data. So you use the "Create Mask By Alpha.vi" referenced in that document to mask out pixels whose transparency is above a certain level. It does not support partial transparency. You could try to implement your own blending algorithm based on the picture control's current pixel values, and the image data's RGB value and transparency value, but it would probably be very slow.
Also, that VI ships with 8.0 and later. I don't know if it's on the palettes but it lives here: vi.lib\picture\picture.llb\Create Mask By Alpha.vi
Good luck!

Movies To JPEG

Is there anyway of using the jmf api to extract all frames of an input movie to jpeg images (i.e. without using the robot class)?

I copied the code for DataSourceReader exactly and made the changes mentioned in this forum. However, my code only captures the first frame of the movie and makes 17 jpg copies of it. How do you make it capture every frame of the movie and make jpg copies of each one?

Lose Jpeg images when editing an existing PDF Form in Acrobat X - All other edits update OK

Have just upgraded to Acrobat X and am having problems trying to update an existing PDF Form which includes jpeg images. After all edits are done and I save, previewing the PDF identifies that all of the existing jpeg images within the form no longer display. Unable to figure out what to do to retain these images from the existing PDF.

Hi,
Based on your other post, the original form was developed in LiveCycle Designer. Therefore you would need to edit the form in LC Designer, to reestablish the link to the image files.

Moving images within Grid View in LR3beta2

Frustrated. In LR3Beta1 I could manually move and place images within Grid View or from the slide view at bottom for purposes of sorting "similar subject" content within a specified Text/Attribute naming. All of this was accomplished from the Parent folder, with no need for drilling down the Tree.
Now, since installing LR3Beta2 I can no longer manually move (sort) within Grid View...unless I am in the lower most folder of the tree. This change is not practical since a tree folder may not match the relevance of my specified Text/Attributes.
Can anyone tell me what I may be doing wrong, or is the ability to manually sort from Parent folder no longer an option?

Here's an example of how I catalog/label/sort my images...
Architectural images project - 3 locations of shootng, 4 areas of focus: Doors, Windows, Facades, Walls
So, I may have 20 images w/both a door and a facade in the shot, 20 images with a window and a door, etc. I prefer to Keyword all of the images as Architectural, and then Keyword those applicable to Doors, Windows, Facades, Walls, etc.
Now, suppose those all go into a folder labeled Architecture.
The next week I get an assignment for Urban settings. It may include shops, churches, etc. However, within those, I decide to Keyword (where appropriate) Doors, Windows, Churches, Shops, etc. That project goes into a folder labeled Urban Settings.
Now, let's say I have a request specifically for "Doors". Now, those Doors are spread across multiple folders at this point so I have no opportunity to manually sort all of the doors my similar content if they fall into multiple folders. Doesn't matter that I have pulled up Doors through Text, I still cannot sort them by similar style, shape, color, etc since they are spread across multiple folders.
In the 1st beta, I could slice and dice a hundred ways to arrive at a final view and then...sort those so that they always appeared that way whenever I called them up again. Didn't matter that they were in multiple folders. That was extremely useful and...sweet.
Any ideas?

View Aquired Image in a Tab control

In order to conserve space I would like to view a live image, aquired from a 1409 board,in a page of a tab control. Also to decrease cpu usage I have set up a Low Level ring. I have tried sending the image to a picture control, but the image is choppy (even if I slow down the loop). My image is perfect in a Vision Window, but this cannot be used as a control on a page. Any suggestions?

Terry,
Bruce has the right idea, try making a child panel and use WindShow to hide or show the display....Attached is an example I wrote using multiple boards and displaying two images on the pages of a tab control...I hope this helps.

Iplimage to picture control

Dear Guys,
While integration of opencv libraries in LabVIEW i had struck with this.. I can able to display the processed images in the window handle. i want to display it on the same iplimage(opencv image) to .NET Picture control or LabVIEW Picture in the front panel.. How can i do this. Can someone help me to sort out this issue...
Waiting for your reply.

You can convert IplImage to Bitmap image to show in .Net Control or Convert IplImage to 2D array to display on to the Picture control of labview.

plz help

Don't forget to use the "Code Formatting Tags",
see http://forum.java.sun.com/help.jspa?sec=formatting,
so the posted code retains its original formatting.

Using QuickTime Pro to convert a series of JPEG images into a QT movie?

Can I use QuickTime Pro to convert a series of JPEG images into a QT (uncompressed) movie? Thanks...
Windows XP

Yes.
One of the features of the QuickTime Pro upgrade is "Open Image Sequence". It imports your sequencially named (1.jpg, 2.jpg) liked sized images (any format that QT understands) and allows you to set a frame rate.
http://www.apple.com/quicktime/tutorials/slideshow.html
You can also adjust the frame rate by adding your image .mov file to any audio clip. Simply "copy" (Command-A to select all and then Command-C to copy) and switch to your audio track.
Select all and "Add to Selection & Scale". Open the Movie Properties window and "Extract" your new (longer or shorter) file and Save As.
As you've posted in the Mac Discussion pages but your profile says XP you'll need to subsitute Control key where I reference Command key.

I think it does that for QuickTime if you don't define the lineStride value in the VideoFormat (lineStride = pixelStride * width).
