Image quality

[malonso]

Hi All,

 

 

 

Another tip of the hat to the Fusion Charts team as they continue to develop new capabilities and improve older ones. It has been several months since I checked the site and the amount of changes you folks have made is astounding, great job.

 

 

 

I was testing out the new feature that allows you to save the chart as an image - I cannot tell you how long I've been getting hounded about this one - and I was wondering if maybe I am doing something wrong as the quality of the image seems a little off (see images below).

I am really sorry to even bring this up since this awesome feature is not even a week old and I am hoping that it is just me screwing something up. Is there a way to change the image quality, or anything else for that matter, that might help to achieve a clearer image? Again I am sorry about mentioning this and I am sure that it is just something I am messing up. Happy Holidays and keep up the good work in the New Year.

Hi,

 

 

 

Can you please send me the XML data you're using and with which chart SWF? We tried it with several charts and couldn't get this error.

 

 

 

Btw, the image quality setting is done in the ASPX page or PHP page.

Hi Pallav,

 

 

 

I am also getting this same problem but on the Powercharts Radar Graphs. When I use the 'Save as Image' function the fonts on the graph get distorted in the exported jpg.

 

 

 

I have noticed it only happens when I apply styles to the graph using the styles and application tags. This is a problem as my client has asked for certain styles to be applied to the captions etc on the graph.

 

 

 

I am using PHP version of the image save (FusionChartsSave.php)

 

 

 

The distorted jpg using 'Save as Image' with styles applied to the graph:

 

 

 

 

 

 

 

 

How it is supposed to look (this is a screenshot taken in the browser then saved as GIF in Adobe Photoshop):

 

 

 

 

 

 

 

OK jpg using 'Save as Image' without styles applied to the graph:

 

 

 

 

 

 

 

 

Here is the XML I am feeding the graph which produces the problem:

Any advice to get around this problem?

 

 

 

 

 

Thanks

 

 

 

Kind Regards,

Jonathan,

 

 

 

Can you make sure you're using v1.1 of the PHP image saving script - just look at the first comment in the file to see the version?

In the FusionChartsSave.php file I cannot see any version comments?

Here is the code:

Where can I obtain version 1.1 from?

Thanks

Kind Regards,

The Flash charts are displayed on a majority of devices and the JavaScript charts on devices that do not support Flash, all of it without writing a line of code.

 

Automatic rendering of JavaScript charts on devices (like iPad and iPhone) where Flash player is not supported.

* Support for line breaks and wrapping in all text elements including: caption, sub caption, X-axis title, Y-axis title, Labels and tooltips.

 

* In Line charts, data values can now be positioned either above or below the dataplots. Automatic positioning of data values is also supported.
