Serious Problem with Images

[Anu maheswari]

Hi friends,
I'm having one serious problem while dealing images. I 'm in need to find
the size of the image occupied in memory. How to find that.


Also, how to find the properties of the image which should provide number
of colors for that image ? That is, by using pixel grabber class, we can
get the individual pixel and do the calculation, but that will be giving
only the number of colors used in the image. But, what I need is total number
of colors., irrespective of used or unused.

thanks in advance

Hello,
getting the size of an image sometimes causes troubles
heres a trick I learned to overcome

// creating image
Image theImage = createImage(somewidth, someheight);

..... etc ... etc

// get sizes
while(theImage.getWidth(null) == -1){}
while(theImage.getHeight(null) == -1){}
int width = theImage.getWidth(null);
int height = theImage.getHeight(null);

As for other question dont quite understand what you want,
hope this was of some help
