[Phpmyadmin-devel] Visualizing GIS data.
Hi all, I have pushed into my repo, the code for visualizing GIS data. I used SVG for this purpose and i'm writing the SVG tags accordingly. This allows the users without JS support also to view the visualizing oppose to using jQuery SVG to generate SVGs. Further it allows the SVGs to be saved, which is one of the upcoming features. However I use jQuery SVG to manipulate the SVGs (zoom and pan), so the users with JS support gets a better user experience. I have also integrated two small libraries [1],[2] to allow panning the SVG on dragging and zooming on mouse wheel movement. These are not strictly needed but nice to have ones. One problem of SVG is the IE versions <=8 does not support is. I am using the GD library to generate a PNG image for them and this is in line with saving those visualization to various formats. You can test this out at my demo server[3] using the data in the opengis table. Please be kind enough to share your comments. -- Thanks and Regards, Madhura Jayaratne [1] http://brandonaaron.net/code/mousewheel/docs [2] http://threedubmedia.com/ [3] http://demo.phpmyadmin.net/gsoc-madhura/index.php

Please note that saving the visualization to various formats (SVG, PNG, PDF) is still not working. So please exclude them from your testings and trying outs -- Thanks and Regards, Madhura Jayaratne

The basic zooming and panning functionally works well. But, when I tried to zoom using mouse wheel, the page also scrolled (my screen height is 800 pixels). Maybe some javascript to prevent the default page scrolling behavior can be added. Also, I think a bounding box in the SVG will be great, since I get lost of the main graphic when I panned and zoomed too much. -- Aris Feryanto

Hi Aris,
The basic zooming and panning functionally works well.
Thank you for taking time to test the functionality.
But, when I tried to zoom using mouse wheel, the page also scrolled (my screen height is 800 pixels). Maybe some javascript to prevent the default page scrolling behavior can be added.
Zooming using mouse wheel happens only when you have the cursor over the image. When you have it elsewhere the page is scrolling. If you still find the prob pls. let me know.
Also, I think a bounding box in the SVG will be great, since I get lost of the main graphic when I panned and zoomed too much.

Yes, Madhura, I had my cursor over the SVG, and the page also scrolled. I've tested this on the latest chrome and firefox on ubuntu 11.04.
Also, I think a bounding box in the SVG will be great, since I get lost of the main graphic when I panned and zoomed too much.

2 things I noticed: - When zooming it doesn't zoom relative to the cursor position - I couldn't use any of the form fields below - the svg area was always in focus I'm using Chrome under Windows XP.

Hi Tyron, Thank you for your time.

Yes, I think this should be addressed. I'm looking into it. - I couldn't use any of the form fields below - the svg area was always in

What do you mean by 'form fields below'? You mean the links referring to the GIT version and all(bottom right)? Yes, that link does not seems to work. But the link in the advertisement on bottom left is working. Wonder how that happens.

Fixed. Should be able to see when the demo server updates.
