Perhaps, not surprisingly, we use thecv2.resizefunction to resize our images. As I mentioned above, we’ll need to keep in mind the image aspect ratio when using this function. But before we get too deep into the details, let’s jump into an example: # import the necessary packages imp...
In this OpenCV tutorial, we learn the syntax of cv2.resize() and how to use this function to resize a given image. We can use cv2.resize() function to upscale, downscale, or resize to a desired size (considering or not considering the aspect ratio). OpenCV Python – Resize image Resiz...

I have made a simple highgui functionality to keep/restore aspect ratio after changing the size of the Window. It uses: cv2.getWindowImageRect(self.window_name) cv2.resizeWindow(self.window_name, width=nw, height=nh) However even if it never changes and only calls cv2.getWindowImageRect the...

so we needed it about 10 times its current size at least, if we created in illustrator and resize it, no matter how big we make it, it will look smooth and crisp. the magic of illustrator it constantly redraw image. 对尺寸有高要求的比如广告和商标最好用IA ,固定尺寸的比如商业名片,...
