image

问题 I am currently trying to make a script that will find images with *.jpg / *.png extensions in directories and subdirectories. If some picture with one of these extensions is found, then save it to an array with path, name, size, height and width. So far I have this piece of code, which will find all files, but I don't know how to get only jpg / png images. class ImageCheck { public static function getDirectory( $path = '.', $level = 0 ){ $ignore = array( 'cgi-bin', '.', '..' ); // Directories

问题 I'm trying to send base64 encoded images to a server using HttpUrlConnection. The problem I'm having is that most images gets sent successfully, however some generate a FileNotFound exception. My code for encoding the image can be found below. public static String encodeImage(Bitmap thumbnail) { ByteArrayOutputStream baos = new ByteArrayOutputStream(); thumbnail.compress(Bitmap.CompressFormat.JPEG, 100, baos); byte[] b = baos.toByteArray(); String imageEncoded = Base64.encodeToString(b,Base64

问题 I hope you all are safe. I know this question asked several times but not getting a perfect answer. I just wanted to capture an image from UIView with high resolution the main this is that image should not be a blur. I have tried this code extension UIView { func asImage() -> UIImage { let renderer = UIGraphicsImageRenderer(size: self.bounds.size) let capturedImage = renderer.image { (ctx) in self.drawHierarchy(in: self.bounds, afterScreenUpdates: true) } return capturedImage } } Right now

问题 How can we get the number of rows and columns in an Image table via Opencv. Code for getting boxes in table which I am getting right contours, hierarchy = cv2.findContours(img_final_bin, cv2.RETR_TREE, cv2.CHAIN_APPROX_SIMPLE) def sort_contours(cnts, method="left-to-right"): # initialize the reverse flag and sort index reverse = False i = 0 # handle if we need to sort in reverse if method == "right-to-left" or method == "bottom-to-top": reverse = True # handle if we are sorting against the y
