如果我从像
Image1.Picture.LoadFromFile(imagePath)这样的文件加载图像;并且JPEG I加载比Image1大,这是一个TImage – 如何缩放它以适应？
将TImage控件的
Stretch属性设置为True.
Indicates whether the image should be changed so that it exactly fits the bounds of the image control.
Set Stretch to true to cause the image to assume the size and shape of the image control. When the image control resizes,the image resizes also. Stretch resizes the height and width of the image independently. Thus,unlike a simple change in magnification,Stretch can distort the image if the image control is not the same shape as the image.
如本文档所示,相关替代方案是Proportional属性.
Indicates whether the image should be changed,without distortion,so
that it fits the bounds of the image control.
Set Proportional to true to ensure that the image can be fully
displayed in the image control without any distortion such as occurs
with the Stretch property. When Proportional is true,images that are
too large to fit in the image control are scaled down (while
maintaining the same aspect ratio) until they fit in the image
control. Images that are too small are displayed normally. That is,
Proportional can reduce the magnification of the image,but does not
increase it.
When the image control resizes,the image resizes also.
