Plotting Image on a Map

I know that the MapKit API contains the functionality to place pins on a MapView, but is there any way to plot a small image (GIF, JPEG, etc) at a GPS coordinate?

Reposted ---- Cannot plot Ovals on the Map on mouse Clicks

Hi all...
I am able to load the map of the South Pacific but I am not able to plot ovals on it . The following is my cod and the exception is also given below the code when i click the mouse. code is based on java 1.5 sdk
Please could anyone correct me with the correct code so that i am able to load the map and click the mouse to draw the points. I am having no knowledge of Java so we have to learn on out own to do this project.

Generation of images of the map

Hi,
Some images of my map, are created with a box gray with a button to close. This seldom occurs and for a few levels of zoom.
After I clear the cache of the level of zoom they are generated successfully.
Is there as detect situation in the application?
Thank you.

Any help would be appreciated. I'm sorry I don't know much about how the classpath works and how data is loaded upon running a program, I've been raised in the safe environment of IDE's and buttons to click to run my programs.. :) Then you need to read the applicable class/classpath documentation here:

Roughly put, don't access Graphics object outside the
paintComponent() method.
And, don't use Graphics object other than that is
passed as the argument of the
paintComponent() method for painting on the
component.
If you want to draw on an Image object before
painting it on the component, use BufferedImage
and the Graphics object gotten from its method. After
that, use g.drawImage() method in the
paintComponent() method.
Your grf variable is complete nonsense.
Delete it.
Most importantly: learn Java GUI programming basics
before anything else.

Can't plot image into WDT waveform graph

I'm trying to plot an icon onto a WDT waveform graph but it doesn't seem to be working. The image plots while using the default (array of doubles) data type, but goes missing when I change to WDT. As far as I can tell, the two graphs are the same except for their data type.
Am I missing a step or is this a LabVIEW bug?

I was able obtain the icon on the WDT waveform graph in your code by changing the property selected on its property node to PlotImages.Middle.

Images in Flash Mapping Client??

Hi,
Now, I'm working with Mapviewer using the Flash mapping Client. It works quit well. I'd like to know if you can insert an image like a JPG or GIF.
Thanks

Hi,
What a pity!! :-( We work with aereal images and it is very important for us to work with them.
Do you know if the next version would support it?

Putting a contour image on a map

Hi there,
I am very new to Java 2d, and if someone can help me tell the basic steps/API I should look at to take a contour image ( basically contour lines on a white background) and overlay them on a map image.
What is confusing to me is how to define the shapes of the contours lines to overlay on the map, (its random).
Till now I get an image and overlay on each other via something like following:-
BufferedImage im2 = ImageIO.read(imageURL);
Graphics2D g = im.createGraphics();
g.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.4f));
g.drawImage(im2, (im.getWidth()-im2.getWidth())/2, (im.getHeight()-im2.getHeight())/2, null);
g.dispose();
however the above produces 2 semi-transparent images overlaying each other, I want the specific contour lines to overlay on my map image but not the white background on which the contour lines are on orginally.
thanks,
nandita.

Unfortunately Java only provides the one implementation of Composite, which is really quite frustrating.
You have two solutions.
Firstly, and this is the most effective solution but may be tricky depending on your source data, don't use white as the background: use transparent pixels. Then you can just slap the image on top without using a composite and get the exact effect you want. If you have antialiased contours then the antialiasing needs to be performed in the alpha channel.
Alternatively, you want a "multiply" style composite, where the output is the source multiplied by the overlay. I did write one a while back, I think I basically I rummaged round on the web for a different composite implementation to get the overall gist of it and then yanked out the guts of it and wrote the multiply algorithm.
The only thing you need to bear in mind is this,
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4833528
which means if you implement a custom composite you can only use it to render to off-screen images.
Actually, there is a way of getting the first solution even if you're loading images with white backgrounds, and that's to write a small algorithm to manipulate the image to convert white pixels to transparent ones - you can probably maintain any antialiasing as well. Shouldn't be hard to write - though it will obviously have a performance hit at conversion time.

Problem Loading images in Google/Mapping sites

I have recently bought an iMac, and find that when I search using Google Images, the thumbnails do not load, and the "loading" icon stays pretty much indefinitely.
I also have problems when using mapping in Multimap/Bing/Google Earth, in that the images again do not load properly much of the time.
This is extremely frustrating as these are functions that I use all the time. I downloaded Google Chrome to see if the problem was in Safari, and got the same result, so the problem appears to be in the operating system.

I have since found this thread:
http://discussions.apple.com/thread.jspa?threadID=2199926&start=0&tstart=0
...which suggested that the problem is with the router firewall, and suggests adjusting it. Mine's a Belkin (ADSL Modem with Wireless G Router), which seems to only have an "on/off" option on the firewall.
I tried turning it off, and the images now seem to load normally. However I am not happy about leaving the router with no firewall... anyone got any ideas for more specific configuration of the firewall?

Image Sizing and Mapping

Hi,
I am trying to create a navigation bar here, and I have one
image for the entire navigation. It includes home, about us, etc.
Now I want the image to always fill the horizontal and vertical
aspects of the users browser, so using percentages I accomplished
that. Now I want to map the image so when someone clicks the home
or about us area it leads to a frame below, now when the image size
changes due to variances in the browsers and resolution, the
mapping stays in the same area while the image changes and in
affect the buttons are not in sync with the mapping. What fixes are
there to this?
Thanks in advance!

Create basically 3 images. A center image with all of your
navigation that
never changes size and a left and right background image that
stretches when
the browser size changes.
But, better than that, don't put your navigation images as
part of the
image. Use css styles to create your links with text links
and image
backgrounds that can float over your stretching background
image.
Text links always work better and give the search engine
crawlers something
to look at. They can't see image links (or won't look at
them.)

Image pixelates when mapped onto 3D object

I have created a bottle by revolveing an object in Illustrator. I created a custom sybol and that is not pixelated at all. The symbol is made of text and an image. To the left is the symbol before it is mapped. As you can see the leaf is not pixelated, but once it is mapped it gets pixelated and blury as seen to the right. Does anyone know why this is and how to fix it!!!??

Check your document raster effects settings. You may actually see something with an effect inside the symbol being wrongly rasterized...

How can I use or convert a imaq image to plot images back on waveform graph

Hi
I am currently opening and manipulating (rotate and resize) a PNG image using IMAQ Vision in LabView 8.2.1 This works well and I can display the Image on the front panel using a IMAQ Image Control.
In addition to this I would now like to display the image as a background on waveformgraph. I can do this with the original PNG file by reading it and then flatten it to a pixmap ie make it a Picture but this is of little use as I need to use the manipulated IMAQ image.
Therefor I would like to know how to convert the manipulted IMAQ Image to right Picture Format (without resaving) in order to use it on the PlotImages.Back property node of a wavefrom graph.
I very much welcome your suggestions as I feel it should be easy yet can not seem to solve it. Thank you for your time!!!

Hi Randall
Apologies for replying somewhat late but I have been out of the office for a few days.
Your suggestions and code helped me greatly and led to solving my query so thank you for that.
There is one more thing (well many many more but I will place new posts for those however that you might be able to answer for me.
Following your suggestion to use the image to array function I searched through more examples and found the code that did exactly what I wanted to do. Please see attached.
In this code a For loop is used to add 65793 to the color table. It works very well but I do not know why it is used exactly. Can you exlplain? I also realize I never made it clear that I use grayscale PNG files rather then color images.
Thanks again for your excellent help, it is much appreciated.

SRM-MDM Catalog image mapping

Dear All,
I am trying to map image field but the field does not appears on the web dynpro user interface, can anyone advise me how to map image field in order to display the images in SRM.
And I am using standard Repository SRM-MDM.
Regards,
Aklilu

Hi Aklilu,
Hope you have followed the following steps.
You have created the mask containing Image field and mapped to the end user say User1.
In the WebDynpro UI config logged in as UI Configuration Manager.
Go to Customize Display tab
Select Result set radio button
Select the image filed and add to the display item.
The problem would be you might have included Image field in the webdynpro and forgot to include the Image field in the Mask.
The fact is that the display fields assigned to the user can be over ridden by the mask assigned to the user.
Please check the fields in the Mask and field added using Webdynpro UI Config for the end user.
Thanks,
Arun Prabhu S

Image map rendered correctly in Firefox, but with problems in chrome & IE

Hi All,
I have created a simple application with JSF 2.0.
The page is made by an image with a map. Clicking on the hotspot another page is shown.
I use a graphicImage tag with reference to a map with some link "hotspots".
Everything works fine in Firefox.
But, in Chrom the Image is shown, but the hotspot is not there....
In IE, the page does not open up, and I'm prompted for the download of the file (!?).
Any help? what I'm doing wrong?
Thanks in advance,
