Question

I’m having problems scaling an image in nsimageview correctly. What happens is when the image is loaded, it doesn’t fill up the entire nsimageview. I used NSScaleToFit and it completely stretched the image. Since I don’t know the dimensions of the photo (it changes, depending on what image is used) I can’t set the nsimageview to a size and leave it there. What I want to do is fill the entire nsimageview with an image, proportionally, even if some of the image is cut off.

This is the code that I’m using:

NSString *image_path = [applicationSupportDirectory stringByAppendingPathComponent:desktop_name];
        NSImage *imageFromBundle = [[NSImage alloc] initWithContentsOfFile:image_path];
        [ViewImage setImageScaling:NSScaleProportionally];
        [ViewImage setImage: imageFromBundle];

Answer 1

I made my own solution, since the ones that were built-in didn’t work.

NSRect frame = [MyWindow frame];

   if (abs(windowHeight-[imageFromBundle size].width) > abs(windowWidth-[imageFromBundle size].height)) {
        frame.size.height = windowWidth;
        frame.size.width = 1+windowWidth*(([imageFromBundle size].width/[imageFromBundle size].height-(10*pow([imageFromBundle size].width, 2))/(pow([imageFromBundle size].height, 2)* windowHeight)));
    } else {
        frame.size.width = windowHeight;
        frame.size.height = ((windowHeight/[imageFromBundle size].width)*[imageFromBundle size].height);
    }

    [MyWindow setFrame: frame
             display: YES
             animate: YES];
