Hi,

I'm doing my project as image editor by using JAVA.

Here I've a doubt about how to get the image pixel, and want to increase the pixel rate, for increasing the quality of an image.

Please reply and help me...

Thanks

If by "Increasing the Pixel Rate" you mean increase the resolution of the image, you cant.
The highest resolution available is the original image taken.
(Eg. 1.2 megapixel image from a phone)

An image's resolution can be reduced, but once reduced, it cannot be increased again.

Solution 1

You may use the PixelGrabber[^] class.
Example of usage here[^].

BTW what do you mean with :"I want to increase the pixel rate"?

[Update]
If you need to scale the image without lossing much quality, why don't you use the getScaledInstance method of the Image class (with SCALE_SMOOTH)?
