eXorithm – Execute Algorithm: Discuss Algorithm round_corners

by ToneDJCampbellin Comment

round_corners     version 0.2     Round the corners of an image. Transparency and anti-aliasing are supported.Subject: integration error

niwdalg posted: Dec 4, 2011 09:45 am [reply]

hi,

Can you help me in integrating this code? i am getting errors.

can you please give an example how this is integrated in image tag?

Subject: Image getting resized

Hi,

Thank you very much for your code. Finally I could get the transparency working on my thumbnails. The only problem is that the script is returned the images in a different size. I send thumbnails on 150px/150px and it returns an image with 214px/214px.

Any idea on how to fix this?

Thanks

My bad. It was my fault. Your script works perfect 😀

Embed This Algorithm

This page will help you embed the algorithm draw_cube on a page on your own website. Just configure the inputs, then click the generate button to get a snippet of code you can paste onto your site. You have two options.

  1. You can embed the entire form. Users will be able to enter their own arguments, and will need to press the run button to execute the algorithm.
  2. You can add only the output of the algorithm to your website. There will be no argument inputs or run button.
