Hi group I already posted this problem yesterday, and I''ve found a
"solution", but I don''t like it, in my opnion there has to be an easier way
to do this, but I can''t find, I hope some one can help me with this. Just
copy paste the code in an empty form and press the draw button, then press
the resize button to see what it does, but I just don''t like the way I do
it, and I can''t seem to find an easier way

推荐答案

彼得，


取决于你想做什么，你真的想拍一张小图片吗？或者你想在一个较小的图片框中显示图片。


当我想剪切图片的某些部分时，我使用了一种这种方法。


当它以另一种方式显示时，我会使用它的sizemode

picturebox。


Cor

Peter,

Depends on what you want to do, do you really want to make a smaller picture
or do you want to show the picture in a smaller picturebox.

I use a kind of this methode when i want to cut of parts of the picture.

When it would be for showing in another way I would use the sizemode of the
picturebox.

我真的想要调整图片大小然后保存它，因为我需要128 * 128的

图片

彼得，


而不是缩略图，因为这是一个特殊的方法？

Peter,

And not a thumbnail, because therefore is a special method?
