Cursor moving and autosize of Image Display
I have LabVIEW 7.1 and vision7.1. I want the size of Image Display in the front panel to be auto enlarged when the cursor is moving into its field and to be auto shrunk when the cursor is out of it. how can I do?
thank you very much
I don't have vision, but the technique should be universal.
Here is a quick example in LabVIEW 7.1, is that what you had in mind?

Need to get rid of flicker in between image displays--the PC on which LabVIEW 8.2 is installed is routing images via LabVIEW code & 'extended desktop' to a typical visual projector and between each image display is a flicker--that we need to remove

How are you running this program? Is there a top level vi which calls the ones you posted? The Display image on screen.vi will display two images in succession, but according to the note on the block diagram the second image is blank. It seems as though this would intentionally create a flicker.
The sequence structure is unnecessary. Dataflow will determine the order of execution. The only exception is the time delay in the third frame. Since it has no data dependency, a single frame sequence may be useful to assure that the delay occurs before the picture is updated. A simple state machine might be a more versatile architecture for what you may be trying to do.
It is not necessary to write the FR.PanelBounds property immediately after reading it, nor is it necessary to read it a second time in the second frame. Just wire from the first read.

Mouse cursor moving mask over another image.
Hi, Is it possible to have where the Mouse cursor is on the page moving mask over another image. Imagine a black screen with a star cut out of the middle(where the cursor is) and u can see the image behind.
Any examples on how to do this?
Can it be done in html instead?Create the mask and the background as movieclips and then assign the mask as the mask property of the bacground movieclip... as in background.mask = msk (where msk is the instance name of the mask).
Then assign a MOUSE_MOVE event listener to the mask and in the event handler for that listener have its x and y properties assigned to be the mouseX and mouseY properties -

I'm not sure when it began, but now my Macbook Air only shows a black background and a User Name and Password dialog box when I wake it from sleep. It used to show my desktop background blurred with my user name and icon displayed with only a text field for entering my password. I'm currently using Yosemite (OS X 10.10.1) and all updates have been done. Any help or suggestions would be greatly appreciated as I know this isn't a real problem, just an annoyance since I couldn't find how to change it back in the System Preferences.
I just have to point out that after looking at a related post (https://discussions.apple.com/message/22661092#22661092), it brought to memory that my issue most certainly began happening after I added some DoD certificates to the keychain. This obviously has something to do with it, but it still leaves me wondering what actually causes this to happen. :/

I just updated to Firefox 11 and the new image display is awful. When I go to an image URL (like this http://www.google.com.br/images/srpr/logo3w.png ) it's displayed with a dark background. It would be better if the background was soft grey... but it's too dark!
Is there a way to use the old image display, with white background or changing the background color?<strike>I don't think that you can use code in userContent.css to fix this</strike>.<br />
<strike>There is no selector possible to set the background-color for the body if there is only an img (body > img:only-child) on that page.<br />
Only a script would be able to accomplish that AFAIK.</strike>
It looks that I'm wrong about this.

Why does moving the mouse over an IMAQ image display slow the GUI down so much?
I have a large application with several vi's running simultaneously under labview 8.6.1. When I mouse over an image display control in one of the vi's, everything slows down a shocking amount in all the other vi's. The windows task manager does not show a large increase in CPU use. My pc is has a quad cpu with 4GB of RAM, and the CPU and memory loads do not appear to be terribly taxing to the system. However, many of my vi's apparently come almost to a standstill if I just move the mouse in a circle around my image control.
This looks like it is largely a GUI display issue. If I make a new vi and put a while loop in it that only displays the iteration loop number to an indicator, I can see the iterating occurring, then stopping totally when I mouse inside the image display control. When I stop moving the mouse inside the control, or when I move it outside the control, the interation loop number jumps up, as if it had been incrementing behind the scenes the whole time. So only display of the interating was halted.
This problem occurs even if the vi with the image control is not executing. If the vi with the image control is open but not running, and I mouse over the image on it, the other guis all come to a screeching halt.
Does mousing in the image display control really utterly crush all other guis in all other labview windows? Is this an issue inherent to the image display control? If so, is there anything I can do about this?
Also, this issue is not entirely limited to display. I started looking at it in greater detail because this issue also exposed what I think is a race condition in my code. I have a vi that acquires an image from a ccd and puts it into an IMAQ image.ctl. This image then gets passed up to a vi up the call chain, and is put on a queue and sent over to be de-queued by a vi that has the image display control. Here's the kicker: when I mouse over the image display control, the image successfully gets acquired inside the subvi, and if I probe the wire leading to the output IMAQ image display.ctl, I see the image. If I simultaneously probe the wire coming out of the subvi one level up the call chain, the image gets lost about half the time. This only happens if I am mousing in the image display control IN A TOTALLY DIFFERENT AND SEPARATE VI. If I bump up the priority of the ccd image acquisition vi to 'highest priority', the problem only happens about 1% of the time, and I really have to mouse around to make it happen. Still, it's disturbing that mousing in the GUI in one window results in a failure of a separate subvi to simply pass an image up the call chain. I understand that IMAQ images are referenced rather than passed by value, but I don't see why there should be a failure to pass the image up the call chain. I've looked for a race condition, but can't find one.
EricI have finally been able to replicate the behavior that you are seeing on another computer once the image was large enough. Here are a few notes about this behavior:
First. The UI only slows down when the images are large, 16 bit images. The reason why this is unique to 16 bit images is that they can only be displayed on the front panel as 8 bit images. The workaround that Weiyuan suggested to change the 16 bit display mapping hints towards the root of the problem...that any time a mouse runs over the indicator, Windows asks the entire image to re-draw (having a separate indicator overlapping the image will create the same behavior). With a 16 bit image, not only does the image have to re-draw on the screen but the 16 bit pixels need to be mapped to 8 bits. When setting the 16 bit display mapping to Full Dynamic, this requires mor computation/pixel than 90% dynamic or one of the other mapping schemes.
This is expected behavior if your program is running and you're trying to display a large 16 bit image. To fix this behavior there are a couple options:
Change the 16 bit display mapping to something other than full dynamic. You can choose which 8 bits to display or if you want to map the bits.
Resize the image just for viewing purposes on your front panel (since you aren't going to view every single pixel of you image on the screen). You can use the IMAQ Resample.vi to do this. This will allow you to take your 1500x1500 pixel image and only display a 500x500 pixel version.
If you are interested in viewing small details of the large image, consider just displaying a smaller region of interest at a time.
Let me know if any of these solutions work for you. Good luck on your application.

I just bought an Epson Stylus Pro 3880 and the printed images look yellow. I calibrate my MacBook Pro monitor with a ColorMunki Display. I want to make sure my Lightroom print settings are correct.
This what I have been trying...... Maybe my eyes are screwed up or don't understand the process....
What I have been trying to do is squint and make the apple disappear by moving the sliders around in each step. Is that correct? -

What I want to do is , have two images on image displays and the pass them through the same setup as the pattern matching example to get the number of matches , I have attached what I have done and also given the pattern matching example program as well.
Hope to get answers back soon,

Pattern Matching Example.vi 100 KBHi there!
The example used can be adapted for comparing two images, however the algorithm and coding for finding the differences is more specific to your actual problem. In terms of the loading and displaying of the images, this can be done in the same way.
Once you have some sort of algorithm, then you can automate the learning and matching by simply wiring them in order. (in the example, these are put in case structures as they are waiting on response from the front panel)
I hope that this helps,

I have downloaded and installed Lightroom for a 30 day trial. Library works fine, but when I try to edit images in Develop, I can't see the full size image just a blue box with a white X on it. If I switch on to Before & After mode, the image displays fine in the before, but still just blue box in the 'after'. Can't find any answer to this anywhere! Please help as my trial days are running out.

Image: display from local drive, upload to server file system, and display from server
Hello,
I am using jdev 11.1.2.4.0...
The requirement is that users would like to upload images from their local drive to server drive and they would like display images from server drive later.
We don't want to keep images in database. I am not sure what the solution should be; however, I plan to ....
1. create a table to keep an information of images -- image_id, image_location (server drive), image_filename
2. create a page where users can enter image information and specific filename from a local drive (I think I will use inputFile component) and provide the preview button to display an image on screen before save it. To save data is to save information to the database and copy an image file to the server drive (the destination location for image files is predefined.)
3. create another page where users can browse information from the database and display an image for a selected record by getting from the server.
I need suggestions on...
1. how to display an image on page from the local drive?
2. how to copy a file from a local drive to a server?
3. how to display an image on page from the server drive?
Thank you.

Where Timo saves images to the database, you save it to the file system (examples on how to do this from Java are available plenty if you just Google for it). Similar to Timo you then use the image tag to display images. The difference is that you can directly add the URL from the database table.
The benefit of using a database to host images is that you are not dependent on file server structures though

Moving and Tilting the Camera for an optimum Lens Profile Creator image set
When framing the chart in different areas of the image frame, use a combination of physically moving and tilting the camera to achieve an optimal balance for LCP generation.
The following two passages are from the AdobeLensProfileCreatorCalibrationChartShhtingGuide.pdf
Page11/a -Move camera a bit to the left (so that when turning to the right to face the chart, it is about 10 to 30 degrees). Take a series of shots similar to the first three, above, except that the chart is framed at the center-left, top-left, and bottom-left areas of the image.
v. Move camera to the right, and do the same for the center-right, top-right, and bottom-right areas of the image
pg11/e - When framing the chart in different areas of the image frame, use a combination of physically moving and tilting the camera to achieve an optimal balance for LCP generation.
i. Only moving the camera to frame, so that image plane stays perfectly parallel to the chart, can have an adverse affect on LCP calibration data.
ii. Only tilting the chart may cause depth-of-field issues, where part of the chart may go too far out of focus due to the large angle of the chart in regards to the image plane. This can also have an adverse affect on LCP calibration data.
Does this mean to center the camera with the center/center shot so that the film plane is parallel with the calibration grid, then only use camera tilt on the tripod up and down for the top center an bottom center image. Then move the camera/tripod left (so that when turning to the right to face the chart, it is about 10 to 30 degrees) AND also pan the camera left to shoot the left top center and bottom image.
I think this combination of instructions have me stuck. Move left but not so much that the calibration target image is parallel with the film plane then pan the camera to get the desired framing.
Would I be correct to say - move left until the angel to the calibration image is 10-30 degrees and then use camera pan on the tripod to get the image framed properly. ... Is the desire to move as little as possible, or pan as little as possible, or to balance moving and panning in some way.
I am profiling a Nikon D7000/TAMRON 11-18mm F/4.5-5.6 lens and have a large target 36"x48" and read that I should shoot at minimum focus distance, 3x minimum, and 5x minimum which equates to 9.8 inches, 29.4 inches and 49 inches... I use this combo to shoot home interior shots at an focal distance of more like 10-20 feet from surrounding walls.. would I also need shots at (120 inches?) 10 feet?
I really (really) want to get the distance to subject and camera moving/pan combination right.
Please help.There are a number of things darks/flats/bias can't remove: curvature, coma, pincushion, chromatic aberration. Some of those (pincushion i.e. showing stars on the chip in a slightly different position from their true position) may or may not be correctable with this sort of an app. It's possible using outside data (comparing the star locations in the image to their true locations in a catalog - that's a common astrophotography measurement and only takes seconds). Correcting curvature (differing focus off axis) chromatic aberration and coma (distorted star shape off axis) seem just what this app is about.
Printing a checkerboard on a nearby hill top sounds involved. Maybe I could get them to plough it in a regular pattern? :-)
The camera does not capture the data you mention. The images are usually in FITS format which has an enormous amount of data about the focal length, exposure time, amount of atmosphere through which you are looking, etc.
Calculating from the book value for the lens(es) camera chip etc would likely not be give a better result than the value obtained before correction. In some designs of scopes, particularly the most common ones, the focal length changes as you focus for example. The lenses and mirrors, comparing one scope to the next, are not perfectly identical.
But a dense star field would be something against which you could measure changes in star shape, focus, chromatic aberration and possibly even position. Once you figured out the parameters for your particular scope+corrector lenses+camera setup you could then use that profile thereafter.
I'd love to chat with that engineer I had heard you have one person who got a Meade SCT and started astroimaging just to learn the things we need and most astroimagers do use photoshop.

Table layout and image display problems
Im having a few problems at the moment, designing a layout
using tables. I need to have 3 seperate tables, 1 for the left
side, 1 for middle and 1 for the right. However I can only get the
left and middle table on the same row, after that the right table
jumps down to the next row.
My second problem is with some images displaying in the
preview. 3 images wont display, they are the same extension (.jpg),
in the same folder as the rest but unlike the others wont display.
I can swap them out for other images which display fine so I cant
understand why they arent showing.
Any help would be most appreciated.> Im having a few problems at the moment, designing a

Use a three column, 1 row table, and put one of your tables
into each of the
three cells.

Indesign image display is very slow and jerky
good morning
I contacted Adobe Customer Service in Italy because I have big problems with the Creative Suite CS 5.5, in particular with Indesign and in general with the display of images of AI and Acrobat.
As I work with Indesign image display is very slow and jerky. Even with AI and Acrobat work experience is not good, the images are jerky and there are hesitations in the fluidity of view.
The software is installed on windows 7 64bit Utlimate, the workstation is very powerful: Supermicro motherboard, dual Xeon E5620 2.4ghz, 16gb ram, SSD OCZ vertex4, PNY Nvidia Quadro 4000.
The customer service has sent me several tips for email, I have followed all the instructions but I did not get results. In conclusion, when I pointed out that reading on the forums I was not the only one who showed this problem and after discussing about my hardware configuration, they told me that the problem is probably due to the fact that I have two Xeon processors!
In efects had observed that CS 5.5 on my notebook works better, but I never thought about having problems because the PC is powerful. I checked the CPU and GPU when using Indesign and I could see that uses a single CPU, and most "only 1 core"! But of CPUs in the system there are two for a total of 8 cores. Indesign seems to use only 1/8 of the available computing power ... In addition, practically does not use the GPU (only 10-15%).
From the customer service was suggested to disable or remove a processor from the system. All this seems to me incredible. I use the workstation for applications that can take advantage of the power of the machine, should I remove the processor whenever I have to use CS 5.5? If things are this way I'm thinking of asking if Adobe buy me a PC with a single processor only for use with CS 5.5 ...
Thank you.Interesting idea, I'll investigate in this direction, I should try to make a mirror of the ssd on a traditional hard drive, exchange them and see if the situation changes. It must, however, be a further factor in the eventual bad combination hardware ... on my laptop I have: windows 7 x64, intel core i7 processor, 16gb of ram, nvidia quadro 3000m, and .... a ssd ocz agility 3, but indesign is more responsive.
But why indesign should be influenced by the hard-drive? With 16gb of ram and working files on NAS because in design interacts with the hard drive?
