If you want to create a new image file, you specify a new image file inside of the save() function. In this case, I created a new image file, examcover_rotated90.png. So, we'll have the original image, along with this newly created image file, which is rotated 90° counterclockwis...

All the rotation options above define rotations in steps of 90 degrees. If you need to rotate an image by another angle, then you can use .rotate():Python >>> rotated_img = img.rotate(45) >>> rotated_img.show() This method call rotates the image by 45 degrees counterclockwise, ...
you can now use the methods and attributes defined by the class to process and manipulate it. Let's start by displaying the image. You can do this by calling theshow()method on it. This displays the image on an external viewer (usually xv on Unix, and the Paint program on Windows)....

showStartScreen()函数将旋转 Surface 对象上的图像。第一个参数是要制作旋转副本的 Surface 对象。第二个参数是要旋转 Surface 的角度。pygame.transform.rotate()函数不会改变你传递给它的 Surface 对象,而是返回一个新的 Surface 对象,上面绘制了旋转后的图像。
该方法首先创建一个 Web 视图小部件,并将其添加到选项卡小部件的新选项卡中。 现在我们有了我们的 Web 视图对象,我们需要连接一些信号: webview.urlChanged.connect(lambdax: self.tabs.setTabText(tab_index, x.toString())) webview.urlChanged.connect(lambdax: self.urlbar.setText(x.toString())) ...
Ubelt contains functions to import modules dynamically without using the python import statement. While importlib exists, the ubelt implementation is simpler to user and does not have the disadvantage of breaking pytest.Note ubelt simply provides an interface to this functionality, the core ...
