Image width resize new!
by joostvm, 15 years ago
My image upload works, the images will upload in 2 folders, but the resize don't work's fine. The first uploaded image will have a width of 200px, the second image will have a width of 800. This is my code:

$handle = new Upload($_FILES['Filedata']);
if ($handle->uploaded) {
  $handle->image_resize            = true;
  $handle->image_x                 = 200;
  $handle->image_ratio_no_zoom_in = true;
  $handle->file_new_name_body = $_GET['nieuwsid'];
  $handle->Process($targetPath."klein/");
  
  // we now process the image a second time, with some other settings
  $handle->image_resize            = true;
  $handle->image_x                 = 800;
  $handle->image_ratio_no_zoom_in = true;
  $handle->file_new_name_body = $_GET['nieuwsid'];
  $handle->Process($targetPath."groot/");
        
  // we check if everything went OK
  if ($handle->processed) {
    echo '1';
  }
  $handle-> Clean();
}

But, my images are 100 and 150 or so pixels. When the image width is larger then 200 and/or 800, the image(s) must be resized, other the size must be original size.

How can I do this?Reply

Using image_ratio_no_zoom_in should be doing what you want. If the image's width is smaller than 200px, then the image will not be resized. Isn't it what you want?

What are the dimension of the images that you are uploading? If it doesn't do what you want, can you copy here the log produced by the class?Reply

The image before the upload is 2048 x 1536. When the upload is done, the first image should have a width of 200px, the second picture 800. When the upload is finished, both pictures are uploaded, but with a width of (must be 200) 150, and the second image (must be 800, right?) 200.Reply

Could you tell me how to make a log?Reply

At the end, before calling clean();
echo $handle->log;

Your image is being resized to fit within 150x150 by default. So if you set only image_x to be 200 (or 800) and not image_y, then image_y defaults to 150. So for the second process(), you are resizing within 800x150, and because your original image aspect, it ends up resizing into 200x150 to keep the ratio.

This is why your image is always being resized to an height of 150 pixels. Set image_y to be something (150 pixels, or 600 pixels, etc...) and it will work.

If you use image_ratio_no_zoom_xxx, you must set image_x and image_y.Reply

Yeah, that seems to work fine! It's now: 800 width, 600 height, what meens: The image width will never higher then 800, and the height of the image will never be higher then 600? If so, great!Reply
