How do I change the size of the point tool in an image

Dear LabVIEW fans
I want to have a very large "Point Tool" in an image display, actually it should cover the whole image as a crosshair. Does anyone know how do this? I've searched among the long list of image properties, but haven't found anything useful.
Solved!

Lefi,
You can use the Draw Line.vi to create a series of lines corresponding to the crosshairs. The line style and thickness can be changed using the "pen" input the vi. I tetsed this out a bit and attached a screenshot of the front panel and block diagram. I got it pretty close but an extra line seems to be there and i'm not sure why. I'm sure you can figure that part out
The event case captures a user mouse move event for the picture indicator, the coordinates of the cursor are in the event node but need to be converted to be relative to the picture indicator, therefore the subtraction (this may be where I was off a bit). The new coords are input to the Move Pen.vi in order to set the current pen position to the mouse position. Thsi way the center of the crosshairs will be on the cursor.
Hope this works for you.
Dan

How do i change the gray background to an image of my choice

how do i change the gray background to an image of my choice when exporting an swf in indesign cs6. i want like the wooden destop look behind my flipbook. please help.

appletv play audio out of optical out of hdmi and the old alu one play out the RCA too
the typical the white and red plug ins would be RCA if you have a atv2 (the black one) you cant use
RCA as that is analog and optical and hdmi are digital
you can get converters but some would be pricy and could cause delay between image and pictures for video

How can I change the aspect ratio of an image display

I am snapping a sequence of images and using imgPlot to diplay the images. However, due to my camera specifications [it's a Pulnix 9701 with Pixel Size 11.6μm (H) X 13.3μm (V)], the image I get displayed is elongated in the horizontal direction, i.e. if I snap an image of a square, I get a rectangle on my computer display.
How can I change the aspect ratio of the display on my computer? The only parameters I have seen so far just control what portion of the image is acquired or diplayed, but none actually changes the aspect ratio.
Thanks in advance for any help.

If you are using an analog camera, you can set the aspect ratio in MAX. This will correct for non-square pixels.
If you are using a digital camera, I don't think there is a way to fix it during acquisition. You could resample the image to correct the ratios, but that would be a slow, time consuming process.
One other possibility is that your computer monitor is in a mode which is not a standard 4x3 configuration. For example 640x480 and 800x600 are 4:3 ratios. 1200x1024 is not, which tends to distort your displayed images.

How do I change the pointer and workspace size in InDesign?

I installed the new 2014 version of InDesign and now my workspace and pointer are huge but the document is normal size. See pics that show difference from previous version to new. It is kind of hard to see the difference in these pics, but there is a huge difference and very annoying because the workspace is taking up so much of my screen and giving me less area to work in...

Change the font size in the O/S to 124% or less

How do I change the pencil tool to smooth or ink in CC?

In most other versions of flash that I'm aware of, you could change the settings on the pencil tool to smooth or ink, rather than straighten, which straightens out all of your lines and puts in fun corners and makes shapes into rectangles for you.
In CC though, I couldn't find where to change this?
Can you even do this, and if so, how?

These options are available in Flash CC as well. If you can't see them at the bottom of your tools panel, they might be getting cut due to a smaller screen size. Try expanding the tools panel to double column or just undock it and check again.
Let me know if you still can't find them.

How can I change the geo tag of an image in iPhoto '11?

A lot of my old photos either have no geo tag, or have incorrect tags (apparently I took some pictures in the middle of the Yellow Sea).
So, how do I change or at least erase the geo tag for one or more photos? I've tried "Rescan Location" and nothing happens.

And did you look at iPhoto help on adding places?
Add places to your photos
If you have photos that don’t have GPS information, including print photos that were scanned to a disk, you can still map your photos in Places.
https://help.apple.com/iphoto/mac/help/index.html?lang=en#
Watch the movie (about 2 minutes)
View and organize photos using Places
iPhoto matches recognizable location names you enter, such as “Seattle” or “Milan,” to a mapping database. When you add a location to a single photo or an entire Event, those photos are marked on the Places map.
Or, if you have latitude and longitude information for the place where you shot your photos, you can use that information to add the location.
Important: You must be connected to the Internet for the Places feature to show photo locations on the map.
Hide
To add a place name:
Select the photo or Event you want to add location information to.Tip: If you select an Event, the location is added to every photo in that Event. But you can add locations to selected photos without adding locations to them all. To do so, select the photos you want, move your pointer over them, and then click the Info button. Skip to step 3.
Click the Info button in the toolbar to open the Information pane.
Select “Assign a Place” and start typing the location name to see the related names iPhoto suggests.You can type city names, place names (such as “Empire State Building”), and addresses (such as “12345 Main St., Lincoln, NE”).Note: If no locations appear, check to make sure that iPhoto is set to look up locations.
As related names appear, do one of the following:
If you see the location you want appear in the pop-up menu, choose it. iPhoto marks your selected location with a red marker pin on the map in the Information pane.
If you don’t see the exact location you want in the pop-up menu, choose a location that’s nearby. For example, if you took a photo of a star at Mann’s Chinese Theater in Hollywood, you can type “Hollywood” into the location field and then choose the Hollywood, California, option from the pop-up menu. Then go to step 5.A red marker pin appears in the map in the Information pane.
To fine-tune the location, you can click the marker pin (it turns yellow) and drag it to a different location, such as a neighboring town, or a more specific location, such as a particular intersection.You can click the plus and minus buttons to zoom in or out, and drag the map to show a different area.To center the map on the pin, click the circle icon.Note: You can move marker pins only in the small map that appears below Places in the Information pane. You can’t drag marker pins on the full-size Places map.
When you’re satisfied with the location as it appears in the Information pane, click the arrow next to the location name to view the marker on the full Places map.
HideTo use latitude and longitude to add a place:
Select the photo or Event you want to add location information to.Tip: If you select an Event, the location is added to every photo in that Event. But you can add locations to selected photos without adding locations to them all. To do so, select the photos you want, move your pointer over them, and then click the Info button. Skip to step 3.
Click the Info button to open the Information pane.
Select “Assign a Place,” and then type the latitude and longitude, separated by a comma.For example, you can type “24, -110” or, if you prefer, you can use a longer format, such as “24.15988731, -110.50838234.”It’s important to always put the latitude first.
Look at the map to confirm the location, and then do one of the following:
If the location is correct, continue to step 5.
If the location is incorrect, retype the latitude and longitude, or drag the pin to a more exact location on the map.You can use the plus and minus buttons to zoom in and out, and drag the map to center it on a better spot.Note: You can move marker pins only in the small map that appears below Places in the Information pane. You can’t drag marker pins on the full-size Places map.
If you want, you can view the location marked on the full Places map by clicking the arrow next to the location name.
HideTo copy the location of one photo to other photos:You can copy the location of one photo to another photo or photos.
Select a photo that has the location assigned to it that you want to copy, and then choose Edit > Copy.
Select one or more photos that you want to assign the same location to, and choose Edit > Paste Location.The location is added to the photos, which you can then view using Places.

How does one change the folder to which scanned images are saved?

Using a CanoScan 9000F Mark II scanner
Using the ScanGear driver software that came with it
Right now every time I scan something, it is automatically saved in "My Documents", and I have to drag and drop the file where I really want it to go. How do I change it so that the file is saved where I want it to go in the first place. Also, it is automatically assigning a file name so that I have to go to the file and change that to what I would like it to be too. How do I make it so that I can name the file before it gets saved. Neither do I see where it gives me the option to choose the format in which the file is saved; it is saving the files automatically as JPG, but I would like to save them as TIFF or BMP.
These seem to be very standard options; so I don't know why I'm finding it so hard. I must be blind or something.
Thank you for your time and assistance.

Hello barbarossa,
Great question! You can change all these settings through the My Image Garden software. The exact procedure will vary depending on the version of Windows you are using.

How can I change the coding of a background image?

I am close to successfully uploading my first website. My one remaining issue: one of my pages isn't showing properly. When I called my hosting service, they tell me that there is an error in the coding of the background image.
It is currently:
http://cashmerepersonalconcierge.com/ContactUs__files/backgroundimage1.png
There is an extra underscore between "Us_files". It should be:
http://cashmerepersonalconcierge.com/ContactUs_files/backgroundimage1.png
but I have no idea how to change the coding in iWeb. Any ideas?
Here's the full URL for the page: http://cashmerepersonalconcierge.com/ContactUs.html

Thanks! That worked and was a fairly simple pick. Thanks for saving me hours!
I almost have it fixed. One small remaining problem:
My link to the "Contact Us" page isn't working from the top Nav bar. That's the one that is in the iWeb template I used. It's linking to:
http://www.cashmerepersonalconcierge.com/ContactUs.html
which doesn't exist.
The nav bar at the bottom link to:
http://www.cashmerepersonalconcierge.com/Contact_Us.html
which works.
Once again I see the extra space/underscore is the problem, but I can't figure out how to get to it. I resaved my folders and re-uploaed the "Contact_Us.html" page as well as all my other html pages to troubleshoot.
Thanks!!

How do I change the duration of a still image in iMovie to less than 0.1 second?

I am creating a movie using iMovie where I need the still images to be 0.05 seconds each or maybe even less., but whenever I select the still images and go to "Clip Adjustments" and under duration change 0.1s to 0.05s and select "Done", iMovie changes the duration back to 0.1s. I'm fairly new to iMovie and I've been messing around with it for quite a while now and still can't figure it out. Could someone help me?

How do you change the location of a small image within an IMAQ image display?

I have an image that exactly fills the display. But then I want to extract a portion of the image and display that small piece, but have it be in the same location as it was before, not centered in the display (essentially I want to crop the image but leave it in the same location). I tried the 'Image Center Position' property node for the image display, but is resets itself to the center of the display. Can anyone offer any suggestions?
Thanks,
Marty

You misused the Image Center position property : it works only on images larger than the display area. Have a look at the simplified version of your sample vi.
One way to achieve your objective will be to create a black (or white) background image, with the same size as the original image and to paste the small piece over this BG.

You can associate files from the Bridge level and the Desktop level.
In Bridge CS4, go to Preferences > File Type Associations and change it to Photoshop CS4 for the file types you want.
If you want to open files from the Windows Desktop in CS4, these are the instructions:
Do this from the Windows Desktop:
If you want your image file to open in Photoshop and it doesn't, right click on it and choose
Open with > Choose default program… select Photoshop CS4 or CS6 and checkmark "always use the selected program to open this type of file".

Change the point: 3.388443E-4 -- 0,0003388

how can I change the point?
I�ve got the following method to calculate 10^(-3,46)
public double AP1 (double S1)
double s = 123 - S1;
int f = 5;
double c = ((s/20) - (92.4/20) - f);
double base = 10;
double distanz = Math.pow(base, c);
System.out.println(s + " " + c);
return distanz;
the output is 3.3884415613920273E-4
but do I have to change that the output is without E-4 like 0,000338844156
??

How does one change the font size for folders and/or file lists in the Bookmarks Library?

How does one change the font size for folders and/or file lists in the '''Bookmarks''' Library?
Since the upgrade to version 9.0.1 of Firefox, the Bookmarks feature changes are confusing me. They seem to be confusing themselves as well. The list of bookmarks has changed. The font size is so small that my aging eyes cannot read it without fogging the screen with my breath. Some folders are out of alphabetical order (where I know they were previously good), and some are missing altogether (folders to which I frequently add references).
As for missing or deranged files or folders, was there something that I should have done or now need to do to recover those after the upgrade (or before)?
With regard to font size,
1. there is no “Edit Bookmarks” or like option to edit the list in this version
2. the “zoom” option in the “view” list of functions is greyed out when in “Show All Bookmarks” window
3. expanding the browser window has no effect on font size
4. “Preferences” settings for font size has no effect in that window either, including advanced settings
5. “Help” offers none that I can find.
Can any of you Help?!?

Maybe this extension helps:
