问题 This is the code for my background grid Background = pygame.display.set_mode((900 ,900)) Green = (45,198,14) Background.fill(Green) for i in range(0, 900, 50): pygame.draw.line(Background, (0, 0, 0), (0, i), (900, i)) pygame.draw.line(Background, (0, 0, 0), (i, 0), (i, 900)) pygame.display.update() while pygame.event.wait().type != pygame.QUIT: pass I can not get any images to load onto it would i have to convert this into n image and then a sprite or is there a way for me to load images onto

问题 I've used <img src={require('./somRelativePath/image.jpg)} in React many times. However, this time it seems not to be working. There are no errors whatsoever (such as that the image was not found etc.) but the broken image on website. After inspecting the element I was somewhat confused by the transpiled result in browser: <img src="[object Module]" style="width: 5rem;"> It appears as if it loads the image as a component not the acutual file. I've created the app with npx create-react-app and

问题 I am using image_dataset_from_directory to load a very large RGB imagery dataset from disk into a Dataset. For example, dataset = tf.keras.preprocessing.image_dataset_from_directory( <directory>, label_mode=None, seed=1, subset='training', validation_split=0.1) The Dataset has, say, 100000 images grouped into batches of size 32 yielding a tf.data.Dataset with spec (batch=32, width=256, height=256, channels=3) I would like to extract patches from the images to create a new tf.data.Dataset with

问题 I take a picture from the camera preview and then save the obtained byte array into a jpeg file. Now I want to save/encode that image file(jpeg) as a video file (mp4) of 2 seconds duration. I know about MediaMuxer in Android 4.3 and I tried with the examples from https://android.googlesource.com/platform/cts/+/jb-mr2-release/tests/tests/media/src/android/media/cts/EncodeDecodeTest.java, but with no success i.e I get a blank video mp4 file. I transformed an image to mp4 video with ffmpeg

问题 I am new to Mac OS App Development with Swift. But I tried to make the simple ImageResizer app. I have to resize 50k images. After 10 hours, the memory has increased to nealy 120GB. I thought Swift also has Garbage collector. Why does it increase memory? I will show you my code. for i in 0..<paths.count { let path = paths[i] if let image = NSImage(contentsOf: path) { ... if self.resize(image: image, size: size, to: URL(fileURLWithPath: resizedImagePath)) { print("Image saved to \
