如何使用WIN32核心和VC ++将位图图像拉伸到某些特定的Co Ordinates？

Question

I just want to create a program which crops an image and sends the cropped image to some remote location.

I have loaded the image using BitBlt(). I dont know, How to uniformly display all the images ? all of same size. stretching is allowed. I have created a static control and now I want to display all the images inside this static control only...

I am able to display images using STM_SETIMAGE, but the problem is that images are not displayed uniformly. So I thought to resize the images before sending them to SendMessage(). I have tried BitBlt() and StretchBlt() but I dont know why nothing works in my code.

The detailed Code

Any Help, will be appreciated...

Thanks in advance,

Answer 1

You might want to try using StretchBlt() instead of BitBlt(). It allows you to specify the source and destination rectangles which will crop and stretch the image.

如果您将图像内部存储为DIB，建议使用StretchDIBits （）。
