推荐答案

将缩略图保留在数据库中并加载它.而已.您无法快速加载巨大的图像并执行您要说的操作.但是，一个100 MB的图像非常巨大，为什么您需要以该大小显示它?以控件的大小显示它，并在放大时加载更大的图像.我想像一下，需要一个切片库来保持完全缩放的100 MB图像上的平移速度的良好质量.

Keep a thumbnail in your DB and load that instead. That''s it. There''s no way you can quickly load a huge image and do the operations you''re speaking of. But, a 100 MB image is huge, why would you need to show it at that size ? Show it at the size of your control, and load larger images as you zoom in. A tiling library would be needed to maintain good quality of pan speed on a 100 MB image fully zoomed, I would imagine.
