Changing the color of an image
Is there a way to have an image that is allready created be changed in java by passing in the color?
Say I create a circle that is black. Is ther anyway I can change this allready created image's color?

No need to use JPEGImageDecoder to read a jpeg file.
True! Must have been an involuntary reflex on my part ;-)
The links CEHJ posted show about the only way you can do that to a pre-created image.
Is what you are trying to accomplish along the same lines as your previous posts? I thought you were creating the images yourself???
If this still happens to be the case, you could wrap the image your own class, store the drawing operations you are performing, and just call the same op with a different color. For instance, if you draw a black square, store the op and the rect, poly, line, etc. If you want to change it to a red square, get the same op/shape and re-perform it with the new color.

it is not an image i create. would be a red circle made in something like photoshop.... be able to read it in and change the red to another color is what i want to do.
The examples i posted are fine for this
