ryanr23 2 Report post Posted September 30, 2006 (edited) This plugin creates a shadow as if from a direct light source in front of the object in question. As with the other shadow plugins, you need to be working on a layer with transparencies. The shadow is applied to all opaque pixels on the layer. Also, the bottom of the image is assumed to be the "ground" and the shadow is relative to that point.

Rick Brewster 1,459 Report post Posted September 30, 2006 The shadow is applied to all opaque pixels on the layer Are you just checking for pixels with an alpha value of 255? I would suggest, instead, rendering the drop shadow for all pixels and then blending that based on the source texel's alpha value. You can use UserPixelOps.Normal.ApplyStatic() to do this on a per-pixel basis. Paint.NET 3.0 will have some blending utility functions that make this sort of stuff (taking the alpha channel in to account) easier. Quote Share this post Link to post Share on other sites
ryanr23 2 Report post Posted September 30, 2006 Thanks for the feedback! No, the operation isn't simply looking for alpha values of 255, but it isn't much more complex than that. Sorry for the simplistic explanation. It takes the source pixel, converts to black and scales the alpha based on the configured shadow alpha. So if your configured alpha is 115, a pixel with alpha of 255 will get scaled to 115, a pixel with an alpha of 128 will get scaled to 58. Obviously 0 goes to 0. I assume that you are implying that multiple src pixels get mapped to one destination pixel in the shadow in which case you would want to blend the source pixels to calculate the destination pixels value. In which case, I agree... I haven't gotten there yet. However, I might be able to accomplish the same thing by blurring the image before calculating the shadow, rather than blurring the shadow after the fact. I'm not sure... Also, if it wasn't apparent from the original post, the current plugin translates the source layer into a shadow layer. The source layer is not preserved. The result of the operation is a mostly transparent layer that can be overlayed on other images to appear to give it depth. This is how the google maps API works. BTW, I'm not super familiar with the entire Paint.NET API at this point, but by "UserPixelOps.Normal.ApplyStatic()" did you mean "UserBlendOps.NormalBlendOp.ApplyStatic()"?

BoltBait 2,603 Report post Posted October 2, 2006 Wow! Nice job. However, I think you should avoid using the word "Google" in the project. Potential copyright issues. Quote Share this post Link to post Share on other sites
