Cloudinary Upload Fixed Image Height, Variable Width

Question

I require all my image uploads to have a fixed height of 225px and fit in a 225x225 square. The width will vary based on the aspect ratio with a maximum of 225.

The below doesn't allow for a flexible width and just makes every image 225x225.

cl_image_tag("sample.jpg", array("width"=>225, "height"=>225, "crop"=>"fill"))

Here are my requirements:

1) If the image uploaded is 150w x 300h. The result will be 112w x 225h.

2) If the image uploaded is 500w x 250h. The result will be 225w x 225h.

3) If the image uploaded is 500w x 100h. The result will be 225w x 225h.

4) If the image uploaded is 50w x 100h. The result will be 112w x 225h.

5) If the image uploaded is 100w x 50h. The result will be 225w x 225h.

Answer 1

Needed to use chain transformations to accomplish this. Scale first then crop using LIMIT fill. Limit fill only crops if the image is bigger than the size of the crop box, therefore smaller images are not cropped.

array("height"=>225, "crop"=>"scale"),
array("width"=>225, "height"=>225, "crop"=>"lfill")

Full PHP code:

    echo cl_image_upload_tag('test',
        array(
            "public_id" => "filepath",
            "format" => "jpg",
            "callback" => $cors_location,
            "html" => array(
                "multiple" => true
            ),
            "transformation" => array(
                array("height"=>225, "crop"=>"scale"),
                array("width"=>225, "height"=>225, "crop"=>"lfill")
            )
        )
    );
