can you tell how it can be done by manipulating BitmapData??

Hi,

Yes, this is relatively straightforward to do. The described technique works for any UIComponent, not just charts. So, for example, you could pass a VBox with a label containing the title and the chart to ImageSnapshot.captureImage, thereby obtaining an image with the chart and a title. There is an alternative, more involved, approach involving manipulation of BitmapData, but it sounds like the simple solution will work for you.

Is there any way to add the title to image.
for eg:’Line Chart’ to Top of Image when printing the image?

As mentioned in the post, this functionality is only available when targeting Flash Player 10. Since you are using Flex Builder 3, I suspect the project is set to target Flash Player 9 as this will be the default. To change check/change the Flash Player version, go to Flex Compiler in the project’s properties and check/set the Adobe Flash Player Options section appropriately.

I hope this helps.

The above code doesnt works for me.
It shows the error message on the line
file.save(image.data, “chart.png”);

as follows:

1061: Call to a possibly undefined method save through a reference with static type flash.net:FileReference.

I am using flex builder3
It seems like there is no save method available in FileReference class.

Vijay,

I wouldn’t like to say for certain, but I do not believe what you are wanting to do is possible.

Hi Faizal, If you are creating the .doc file in the Flex application then I would guess that this is possible, but the details of how to do this would depend on whatever library you are using to create the file. If you mean that you would like the images to be inserted into a .doc file the user has open on their machine then a different mechanism is required. To do this you would have to base64 encode the image data and pass it to a JavaScript function using ExternalInterface functionality. The JavaScript function can then ensure that the image data is copied to the clipboard, e.g. using the jQuery Copy plugin, thereby allowing the user to paste the image into their document. I hope this helps. Regards, Graham
