    Default removing image background color using java??

    i have a sprite sheet(image) and i want to draw on screen.


    image = sprite sheet image
    x = player x postion
    y = player y postion
    width = player width
    height = player heigh

    public class main extends japplet
    {
     ...
     
     
     public void paint(Graphics g)
      {
          g.drawImage(image, x, y, x+width, y+height, 
    	               0, 0, 40, 40 ,sprite_sheet.m1);
      }
    }

    so on spreet sheet i have a image of player, and its background color is blue. when i drawImage it create image background blue. now i cloud remove the color by using photoshop but i really dont want to do this. bc it will remove part of my player.

    In my opinion, photoshop is probably your best option since you can remove the background without removing the player's color that is similar to the background.

    If the image of the player has a continuous boundary and the color of all the pixels outside the boundary is the same,
    you should be able to write code to change those pixels.
    Are there any folds in the boundary?
    If not do it row by row,
    start at left edge and work to the right towards boundary changing pixels
    then do the same starting at the right edge and work left to boundary.

    With folds, it will be harder unless there aren't any color matches in the player.
    If you don't understand my answer, don't ignore it, ask a question.
