Cropping an image to a percentage?

[Fruity]

What im aiming for is similar to below :

 

1 image - but the total width is cropped depending on the percentage.

 

i have percent to next level as so.

 

percentTNL = ((currentXp - currentLevelXp) / (nextLevelXp - currentLevelXp) * 100);

 

But i dont know how to crop the image to have the percent age D:

 

Sorry for being a nub :3

Is it possible to have the image move to the right and just have the left side covered by something else? I feel like this might be the best option as dynamic resizing or cropping may be a little tough.

g.drawRectangle(x,y,width,height);

                                 ^

                          percentTNL

 

or something along this line... I know it doesn't do exactly what you wanted, but it's much easier.

try this

 

Rectangle bounds = new Rectangle(Whatever bounds you want to crop to on the game screen);

int dx1 = bounds.x;

int dy1 = bounds.y;

int dx2 = bounds.x + bounds.width;

int dy2 = bounds.y + bounds.height;

int sx2 = bounds.width;

int sy2 = bounds.height;

g.drawImage(image, dx1, dy1, dx2, dy2, 0, 0, sx2, sy2, null, null);

 

You can calculate the bounding rectangle by having a pre-defined "full" (100%) rectangle, and transform its width according to your percentage variable.

You can work out the appropriate width like so:

int onePercentImage = (int)(image.width / 100);
int imageWidth = (onePercentImage * percentTNL);

Thank you this worked
