Picturebox，SizeMode缩放和填充

Question

It is possible to set SizeMode Zoom and apply padding?

The following will work:

    ibPic2DLeft.SizeMode = PictureBoxSizeMode.Normal;
    ibPic2DLeft.Padding = new Padding(100, 100, 50, 50);

The following will not work:

        ibPic2DLeft.SizeMode = PictureBoxSizeMode.Zoom;
        ibPic2DLeft.Padding = new Padding(100, 100, 50, 50);

What are the alternatives of padding that are compatible with zoom?

Answer 1

you can better go for this approach, when your image size is less than the size of the picture box, you can use normal mode and when your picture size is bigger than picture box you can use zoom mode. This is the best dynamic approach i found for my application solution in past.

Image oImg = yourImage;

if ((oImg.Height > ibPic2DLeft.Height | oImg.Width > ibPic2DLeft.Width)) {
    ibPic2DLeft.SizeMode = PictureBoxSizeMode.Normal;
} else {
    ibPic2DLeft.SizeMode = PictureBoxSizeMode.Zoom;
}

Answer 2

Put the PictureBox inside a Panel. Set the PictureBox to Dock=Fill. Set PictureBox SizeMode=Zoom. Apply Padding to the Panel.
