Uploader Image Resizer

Uploader Image Resizer

The uploader added to the Imagevue X2.5 release, includes the option to resize images before they are uploaded. This makes it much more convenient to upload images without the hassle of having to resize them first manually. No longer do you need to make a copy of your folder with resized images prior to upload. In the uploader module, you also now have the option to choose the size for your resized images!

How To Resize

To resize images on upload, simply log in to your Imagevue admin and navigate to a folder where you want to upload some images. Click the “upload” button on the top right, and the uploader window will appear. To resize images on upload, make sure you have checked the [ ]Resize to checkbox, and that you are satisfied with the bound box values:

Setting and understanding the Bounding Box

The Bounding box represents the maximum width and height for your resized images. For example, when using the default values of 800 x 800, your image will never be longer than 800px in width or height. If your original image is 4752 × 3168, it will resize to 800 x 533, keeping original aspect of course. If you upload a portrait-aspect image in the same dimensions 3168 x 4752, it will resize to 533 x 800. Basically, it will resize all images within the bounding box limits.

More Examples

If you for some reason want landscape images to be bigger(and longer) than portrait images, you could for example set 800×600 in the bounding box settings. This would create landscape images that are maximum 800 px width, while portrait images would be maximum 600px height. The re may be some logic to this as most screen are horizontal and widescree, can handle wide images, but cannot handle tall images so they might as well be smaller

If you want ALL images to be 800px width no matter what, then set 800 x 99999 in the boundary box settings. This means that no matter what aspect your image is, it will always resize to 800px width, while the height will resize proportionally depending on the aspect. You can also do it the other way around and use the height.

The resizer does not crop images in any way

Other Notes

• The default resize boundary box parameters are 800 x 800. You can change this by going to admin › settings › uploader, and change the width and height.
• The default quality of resize images is set to 95. If you really need to change this, you can open the document iv-admin/js/imagevue.upload.js and change the setting on line 7:

  Imagevue.Environment.resizeQuality = 95;

• The Imagevue uploader is based on SWFupload
