You need to set the format parameter in your call to the save function to ‘JPEG’: from PIL import Image img = Image.open(‘car.jpg’) new_img = img.resize((500,500)) new_img.save(“car_resized.jpg”, “JPEG”, optimize=True)
This is absolutely incomparable matters. Resizing images on the fly, in fact, is like running a DoS attack on your own server. Resize of one usual image require more CPU and RAM than serving one usual request to php script. That’s ALREADY a huge impact on performance. Yet a usual thumbnail being shown not alone, … Read more
I’ve managed to further test this with Imagick: The left half of the image was processed with Imagick and the sRGB_IEC61966-2-1_no_black_scaling.icc color profile, the right half has no color profile associated and shows exactly the same if processed with Imagick or GD; here is the code I used: header(‘Content-type: image/jpeg’); $image = new Imagick(‘/path/to/DSC07275.jpg’); if … Read more
Step 1: Add “intervention/image”: “dev-master” to the “require” section of your composer.json file. “require”: { “laravel/framework”: “4.1.*”, “intervention/image”: “dev-master” }, Step 2: Run CMD; $ composer install If you’ve got this warning: Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. Run update … Read more
Using Bitmap.compress() you just specify compression algorithm and by the way compression operation takes rather big amount of time. If you need to play with sizes for reducing memory allocation for your image, you exactly need to use scaling of your image using Bitmap.Options, computing bitmap bounds at first and then decoding it to your … Read more
For version 4 you have to call asBitmap() before load() GlideApp.with(itemView.getContext()) .asBitmap() .load(data.getImageUrl()) .into(new SimpleTarget<Bitmap>() { @Override public void onResourceReady(Bitmap resource, Transition<? super Bitmap> transition) {} }); } More info: http://bumptech.github.io/glide/doc/targets.html
You can read image from the disk using the image.file constructor. For more features you can use the Image library A Dart library providing the ability to load, save and manipulate images in a variety of different file formats. Sample from the documentation examples Load a jpeg, resize it and save it as a png … Read more
As to the resizing itself, using WPF’s TransformedBitmap seems a bit easier: var bitmap = new TransformedBitmap(bitmapSource, new ScaleTransform( newWidth / bitmapSource.PixelWidth, newHeight / bitmapSource.PixelHeight));
According to this blog post: http://i-proving.com/2006/07/06/java-advanced-imaging/ you can use the Java Advanced Imaging Library to do what you want. The following sample code should provide you a good starting point. This will resize the image, both in height and width, as well as image quality. Once your image is of the desired file size, you … Read more
