In Flex, I am using graphics.codec.JPEGEncoder to save image files that are edited inside application (normal manipulations like brightness etc.) I am able to save files perfectly. What I want to know is that is there any way I can save the image with a better dpi? Say, for instance the image that is loaded and manipulated was originally of 72dpi, now can I save it with a dpi of 150 or 300 ? If so, how to do it.
Doesn't have to be using the JPEGEncoder, if there's any way to do it at all, like using any library etc, I am okay with it. Any suggestions?
Note: If it matters, I am using Bitmapdata to store the image and manipulations and saving the image with JPEGEncoder by supplying it's data as bytearray like below.
var imageBytes:ByteArray = encoder.encode(myBitmapData);

If you say you want to save a 72 dpi image as 150 or 300 dpi image, then it should be in your case essentially an enlargement and you have to use something like bicubic interpolation for this.
