Resize php1/17/2024 ![]() ![]() $wid_src It determine the width of old image. $hei_dest It determine the height of new image. $wid_dest It determine the width of new image. $y_src It determine the y-coordinate of source image. $x_src It determine the x-coordinate of source image. $y_dest It determine the y-coordinate of destination image. $x_dest It determine the x-coordinate of destination image. Parameters Explanation $image_p It determine the destination image. The function imagecopyresampled() accepts ten different parameters. It functions similarly to the imagecopyresized() feature, with the added benefit of sampling the image in addition to resizing it. Imagecopyresampled() copies an oblong portion of one image to a different, seamlessly interpolating pixel values to reduce the dimension of a picture, maintaining a high level of clarity. It returns the boolean value TRUE on success or FALSE on failure. Parameters Explanation $dst_image The destination image resource $src_image The source image resource $dst_x The x-coordinate of destination point $dst_y The y-coordinate of destination point $src_x The x-coordinate of source point $src_y The y-coordinate of source point $dst_w The destination width $dst_h The destination height $src_w The source width $src_h The source height We’ll use the value of this returned constant to figure out what kind of image to use and which feature to use.Īs discussed above, the imagecopyresize() function accepts ten parameters, which are listed below. This function returns a list of items, where the image’s width and height are stored at indexes 0 and 1, respectively, and the IMAGETYPE_XXX constants are stored at index 2. ![]() ![]() getimagesize() in PHPĪfter loading the image, we use getimagesize() to calculate the width, height and the type of the input image. Depending on the type of image we will resize, we will use a different function accordingly. To load the file, we need to use functions like imagecreatefromjpeg(), imagecreatefrompng(), and imagecreatefromgif(), among others. It is not the same as using functions like file_get_contents() to get the image file’s content. Load the Image Before Resizingīefore we resize an image, we must first load it as an image resource within the script. In this tutorial article, we will discuss resizing an image in PHP. ![]()
