How to use
Image Extractor will enable a new template function. It output a complete IMG tag to be inserted into your HTML code. The image source is retrieved from the first image found in the current post. Here is an example showing you how to use it:
while (have_posts()) : the_post();
image_extractor(true, 1, 395, 0, '', '', '<div>', '</div>');
The syntax is:
image_extractor($resize=false, $resize_type=1, $width='', $height='', $class='', $id='', $prefix='', $suffix='')
- resize: indicate if the plugin has to resize the image and store it in the cache folder
- resize_type: there are 3 type of resizing:
- 0 -> image will be resized to the new output size, regardless of the original aspectratio. (default)
- 1 -> image will be cropped if necessary to preserve the aspectratio and avoid image distortions.
- 2 -> image will be resized preserving its original aspectratio. differences to the new outputsize will be filled with white
- width: the destination width. If resize is false, this property only add/change the WIDTH attribute of the IMG tag
- height: the destination height. If resize is false, this property only add/change the HEIGHT attribute of the IMG tag
- class: add or change the CLASS attribute of the IMG tag
- id: add or change the ID attribute of the IMG tag
- prefix: add a prefix to the resulting IMG tag
- suffix: append a suffix to the resulting IMG tag
The resulting effect is cool! You can resize the post dimension as you want! Here is a screenshot!
