Yeah, you can install opencv (this is a library used for image processing, and computer vision), and use the cv2.resize function. And for instance use: import cv2 import numpy as np img = cv2.imread(‘your_image.jpg’) res = cv2.resize(img, dsize=(54, 140), interpolation=cv2.INTER_CUBIC) Here img is thus a numpy array containing the original image, whereas res is a … Read more
WebKit provides the pseudo-element ::-webkit-resizer for the resize control it automatically adds to the bottom right of textarea elements. It can be hidden by applying display: none or -webkit-appearance: none: ::-webkit-resizer { display: none; } <textarea></textarea> This displays as follows in Chrome 26 on OS X: Note: Adding display: none to ::-webkit-resizer doesn’t actually prevent … Read more
You can do this by checking the touch-start point. If it hits one of your four corners you can resize based on the distance between that touch-start point and the current-touch point. (If the touch-start point didn’t hit a corner, we just move the view instead of resizing.) Define the size of your draggable corners. … Read more
I just discovered another problem which might help you. I am using jQuery and I have window.resize event to call a function which will re-position the div appended to the body. Now when I set the LEFT css property of that appended div, the window.resize event get trigger for NO GOOD REASON. It results in … Read more
You can put the textboxes inside a grid to do percentage values on the rows or columns of the grid and let the textboxes auto-fill to their parent cells (as they will by default). Example: <Grid> <Grid.ColumnDefinitions> <ColumnDefinition Width=”2*” /> <ColumnDefinition Width=”3*” /> </Grid.ColumnDefinitions> <TextBox Grid.Column=”0″ /> <TextBox Grid.Column=”1″ /> </Grid> This will make #1 … Read more
If you wish to use CV2, you need to use the resize function. For example, this will resize both axes by half: small = cv2.resize(image, (0,0), fx=0.5, fy=0.5) and this will resize the image to have 100 cols (width) and 50 rows (height): resized_image = cv2.resize(image, (100, 50)) Another option is to use scipy module, … Read more
I got it working from one I made. <?php $dest = imagecreatefrompng(‘vinyl.png’); $src = imagecreatefromjpeg(‘cover2.jpg’); imagealphablending($dest, false); imagesavealpha($dest, true); imagecopymerge($dest, $src, 10, 9, 0, 0, 181, 180, 100); //have to play with these numbers for it to work for you, etc. header(‘Content-Type: image/png’); imagepng($dest); imagedestroy($dest); imagedestroy($src); ?>
Here’s code from my personal grab bag of image resizing code. First, data you need: list($originalWidth, $originalHeight) = getimagesize($imageFile); $ratio = $originalWidth / $originalHeight; Then, this algorithm fits the image into the target size as best it can, keeping the original aspect ratio, not stretching the image larger than the original: $targetWidth = $targetHeight = … Read more
For reference, here is the same program using Swing. Because JPanel is double buffered, it doesn’t flicker as the mouse is released after resizing. import java.awt.*; import java.awt.event.*; import java.util.Random; import javax.swing.*; public class SwingPaint { public static void main(String[] args) { JFrame frame = new JFrame(); frame.add(new CirclePanel()); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.pack(); frame.setVisible(true); } private static … Read more
A way to avoid the main HTML to be affected is to create an off-screen canvas that is kept out of the DOM-tree. This will provide a bitmap buffer and native compiled code to encode the image data. It is straight forward to do: function imageToDataUri(img, width, height) { // create an off-screen canvas var … Read more
