Remember, when uploading files you need to set the formâs enctype attribute to âmultipart/form-dataâ.Īn upload script handles the image upload and resizing the image if required. The thumbnailImage () method simply accepts the height and width of the resized image and can be used as follows: don't mess with images much so idk the whole ratio thing. Of course weâll need to create an HTML form with which users can upload photos: Īs soon as the user hits the upload button a POST request will be sent to a script which will handle the file upload process and show the uploaded image to the user for cropping. Hey, I know how to use the PHP GD functions but how would I resize an image > 1000 width to 1000 width and just resizing the height to w/e needed to keep aspect ratio if the image is set to 1000 width in pixels of course. Now that youâre familiar with the two methods, weâre good to go. The new dimensions are less than or equal to the specified dimensions. For example, a call to thumbnailImage(400, 400, true) on a 1200Ã768px image will produce a 400Ã200px version. We can also pass a third argument known as bestfit If this is set true, the image will be resized in such a way that the new dimensions can be contained within the height and width specified. If either the width or height argument to thumbnailImage() is set as 0, the aspect ratio is maintained. The above code produces a 200Ã200px version of image. The thumbnailImage() method simply accepts the height and width of the resized image and can be used as follows: thumbnailImage(200, 200) Finally, writeImage() saves the result back to disk for us. In this case the code will produce a cropped image of size 400Ã400px starting at 30px from the top and 10px in from the left of the original image. Then we call cropImage() with appropriate arguments. Also, the image should be resized in 500 x 500 px. The image should be compressed while uploading without disturbing its resolution. We create an Imagick object first, passing to its constructor the filename of our image. how to resize the image while uploading using php Ask Question Asked 7 years, 9 months ago Modified Viewed 9k times -2 Please help with the php code to upload an image. The first two arguments indicate the height and width of the cropped region, and the last two indicate the X and Y coordinates of the top-left corner of the cropped area. The cropImage() method accepts four arguments. Since weâre going to create an image cropper, weâll mostly be using the two methods: cropImage() and thumbnailimage(). It offers a simple object-oriented interface to use the API you just need to create an instance of the Imagick class and then call the appropriate methods to start manipulating the images. ImageMagick provides a lot of API methods through which you can manipulate an image. The ImageMagick extension performs image processing using the ImageMagick library.
