Madhura,
I have issues operating panning and zooming. Here is the scenario:
1. Browse world_cities and click Visualize GIS data 2. Click-drag: pans OK 3. Double-click: this is a zoom out, I guess 4. Click-drag: no panning 5. Click "zoom out": data points are enlarging, isn't this a zoom-in?
Marc,
This is a Firefox compatibility problem. Resolved and pushed to the repo. Demo will take some time to upgrade to the new version. Meanwhile if you have Chrome, you can still experience what it's suppose to
do.
Madhura, ok, panning and zooming are fine now.
Is the saving feature ready? I tried to save in PNG and got a bunch of binary data on-screen.
Saving in PDF generates Fatal error: Call to undefined method PMA_GIS_Visualization::toFileAsPdf() in

Hi Marc, In my previous mail to the group, I mentioned that this feature is not yet ready. BTW, this is a feature which is to be delivered in the second half of GSoC (after mid-term eval), according to the schedule. However I started working on it, since it is very much related to what I've done so far. I should be able to get it ready (for all 3 formats, SVG, PNG and PDF) by the end of this week.
Just in case I'm allowed to use Highcharts, could you make your conversion code generic enough so I could use it too? :) And just for your information, the current SVG converter of highcharts uses following post variables to a php file that calls a java tool (source is available btw):
* $tempName string The desired filename without extension * $type string The MIME type for export. * $width int The pixel width of the exported raster image. The height is calculated. * $svg string The SVG source code to convert.
Hi Tyron, For my work I am not doing any conversions as such. I am generating SVGs and PNG separately in their basic forms. It's not that I generate it in one form and converting it to the other. --
Does that mean you use jQuery SVG to generate the SVG and build/use another rendering library that generates the PNG/PDF? Why not just build a converter? That seems like a more reusable solution.
I use GD extension to generate PNGs and will be using TCPDF (which is already included in PMA) to generate PDFs. Since both GD and TCPDF support rendering basic shapes, I find this approach needs only few additional lines of code, which would not have been the case if I am to build a converter.
