Hi

There have been some plugins that have had a quad mark showing ( I have also made plugins with quad showing, but won't upload them )

Anyway Malone once said he checks the plugin submissions and corrects the quad fault.

If you tell us how to correct them then it should save you a lot time and help us produce better plugins.
thanks

The quad never shows up on rendering in AlamDV2 - it isn't possible. Some people made plugins in Illusion which adds a line of light coloured pixels to all the images it renders (god knows why) and these then show up in the AlamDV2 effects they made. Check your images.

The problem is with plugins that don't fade to nothing by the edge of the quad. This creates an obvious 'light box' around the plugin which looks really bad.

Check out this example


The image looks fine. It should make a lovely plugin yes?

This is what it looks like in AlamDV.



Not very good

With luminosity effects this is caused by the image not being completely black by the time it gets to the edge. Even a couple of shades lighter than black can look really obvious when in AlamDV.

The way to fix this is to simply make sure you don't crop the image till its disappeared! Don't do this by eye, 9 times out of 10 you'll get it wrong. Most paint programs have tools that let you create a flood selection (in psp its called the magic wand). Simply select all the pure black around the edge of the plugin. Then invert the selection and you will end up with the bits of the image that you must not crop (ie this is the smallest size your image must be)

Obviously if a submitted plugin has been cropped too much I have no way to uncrop it. So what I do is simply darken the edges of the image until they are properly black. This method isn't ideal and it would be much better if the submitter had just cropped it right in the first place.

The same is true with alpha plugins. The alpha channel should make the image completly transparent by the time it gets to the edge of the quad.

ada yeah. Your method just makes all the images darker. Which would work but isnt as nice as cropping it properly in the first place. Even my method of darkening the edges is a little better because you dont damage the intensity at the center of the image.

Are any of my plugins guilty of this? I try as far as possible to avoid this quad problem, but some may have slipped through my fingers. I always try out the plugins I make in AlamDV2 before I post 'em, but sometimes I may not notice fine lines at the edges or other less obvious problems. I know the slimer plugin has this problem - any others?
