I don't think you can increase the DPI. Assuming you need this for high quality printouts, you could, however, generate a larger image. DPI is just a measure of the number of pixels which are used when taking a printout. If your image is made up of 720 pixels and is used to generate a print 10 inches wide, you're left with 72 pixels per inch. Instead, double the image size to 1440 and then take a printout on the same size of paper, you have 144 pixels per inch.
The downside is that the image will take up big gobs of memory. And if this is done on the client-side, it could possibly bring the client computer down on its knees. Make sure to clear memory after you're done. Setting the bitmap data to null explicitly causes it to be garbage collected immediately in most cases. .p On Wed, Apr 27, 2011 at 1:56 PM, S k R p <[email protected]> wrote: > > Hi All, > > I am getting the generated image of Charts , processes etc from > Java(JFree Charts) to Flex. > But my requirement is to increase dpi of those charts in flex. > > How to do that ...is there any solution for that?? > -- > View this message in context: > http://old.nabble.com/Increase-dpi-of-a-image-%28Chart-%2C-process-%29-tp31485455p31485455.html > Sent from the Flex India mailing list archive at Nabble.com. > > -- > You received this message because you are subscribed to the Google Groups > "Flex India Community" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]. > For more options, visit this group at > http://groups.google.com/group/flex_india?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Flex India Community" group.
