I want to change the colour of the particular thing during the coping process.
For Example:
There is a bmp in which a man is standing wearing a sky blue shirt and a navy blue pent in front of the blue car.
I can copy the image by the following code.

Now, I want that when I open the copied image, the blue colour of the car in the image
turns black.
How can I do this.

  • If you are going to be using .BMP images, you'll have to use the JAI (Java Advanced Imageing) API.
  • Is this image a photograph or a drawing? Is more than one color used in the blue of the car? Is the "blue" of the shirt a different "blue" (RGB value) from the man's shirt?
  • Image filters are good at things like "find all colors of this RGB value and replace them with colors of another RGB value", but are bad at "find the car in this picture, ignore the man standing in front of it, and change these multiple shades of blue to multiple shades of black".
