How to manipulate Image

[vitor.eduardods]

Hey folks,

I have a new challenge for you. How to manipulate image?

As a matter of fact, I need to render an image that should be picked in a list. There is a place where I will render it. But depending on the size of screen I need resize the image to accomodate it in its determinate area. My question is:

How could I load the image, get its properties, like width and height in order to resize keeping its aspect ratio?

I know that there is ImageResource and ClientBundle. But I did not get a way to load dynamic since these classes use @Source annotation in order to identify the resource.

Waiting for ideas...

Hi folks, I figured out how!

Please, if this topic is useful for you, take a look below:

public void setPreviewImg(Image image) {
        
        // reading the current image dimensions
        int cwidth = image.getWidth();
        int cheight = image.getHeight();
        
        // getting the relative available space towards accommodate image
        int wavailable = formVorschau.getWidth();
        
        /* calculating the aspect ratio to arrange the image into the available space
         * this will keeps the image aspect without distortions
         */
        int nwidth = wavailable - 10;
        int nheight = ( ( cheight * nwidth ) / cwidth );
        
        // resizing the image
        image.setPixelSize(nwidth, nheight);
        
        // rendering the image
        formVorschau.addChild( image );
    }

Bye for now!
