So i've been trying for over a day to solve this issue and i'm about to cry lol (ok maybe not that dramatic but close enough).

I'm trying to rotate an image but everytime i try no matter the method or it either truncates or it doesn't resize.

This is what i'm doing in general:

i have an image wich is (let say) 150 x 300 then when i draw it i resize to about 55% of its original size.

but on double click i have to rotate it 90 degrees (goes back and forth to 90 degrees, -horizontal and vertical position-)

and i have tried 2 methods but i get undesired behavior:

this is one:

cardImage is the original full-sized card.
flippedCardImage is where i store the flipped version of cardImage.

public void rotateImage (double degrees){
        ImageIcon icon = new ImageIcon(cardImage);
        BufferedImage blankCanvas = new BufferedImage(icon.getIconWidth(), icon.getIconHeight(), BufferedImage.TYPE_INT_ARGB);
        Graphics2D g2 = (Graphics2D)blankCanvas.getGraphics();
        g2.rotate(Math.toRadians(degrees), icon.getIconWidth()/2, icon.getIconHeight()/2);
        g2.drawImage(cardImage, 0, 0, null);
        flippedCardImage = blankCanvas;

with that code i get the image but it is shrinked.

and with this:

public BufferedImage rotateImage(BufferedImage img, double degrees) {

        //making image with the rotated size
        BufferedImage rotated = new BufferedImage((int) cd.getSCD().getHeight(), (int) cd.getSCD().getWidth(), img.getType());

        //We create a Graphics2D object...
        Graphics2D f = rotated.createGraphics();
        f.translate(rotated.getWidth()/2, rotated.getHeight()/2); //translate half the width and height
        f.rotate(Math.toRadians(degrees)); //rotate the image...
        f.translate(-img.getWidth()/2, -img.getHeight()/2); //translate-back to half the original width and height
        f.drawImage(img, 0, 0, null); //draw image        
        return rotated;

with that when i draw it it draws like if i cropped the 55% sized rectangle off the full sized image and draw that instead of resize it.

how do i do rotate and resize it properly can someone please help me? T_T

You can, but you shouldn't.

If your thread wasn't informative enough for people to respond, shoving it through their throats certainly won't help.
