推荐答案

使用 PictureBox 控件来显示图片。对于图像的大小，您可以使用PictureBox的 SizeMode [ ^ ] 。



正常：图像位于PictureBox的左上角。如果图像大于包含它的PictureBox，则剪裁图像。



StretchImage： PictureBox中的图像被拉伸或缩小适合PictureBox的大小。



AutoSize： PictureBox的大小等于它包含的图像的大小。 />


CenterImage：如果PictureBox大于图像，则图像显示在中央。如果图像大于PictureBox，则图片放在PictureBox的中心，外边缘被剪裁。



缩放：保持尺寸比例增加或减少图像尺寸。

Use a PictureBox control for displaying the image. For the size of the image you can PictureBox''s SizeMode[^] property.

Normal: The image is placed in the upper-left corner of the PictureBox. The image is clipped if it is larger than the PictureBox it is contained in.

StretchImage: The image within the PictureBox is stretched or shrunk to fit the size of the PictureBox.

AutoSize: The PictureBox is sized equal to the size of the image that it contains.

CenterImage: The image is displayed in the center if the PictureBox is larger than the image. If the image is larger than the PictureBox, the picture is placed in the center of the PictureBox and the outside edges are clipped.

Zoom: The size of the image is increased or decreased maintaining the size ratio.

Good luck,
