[How is the "Overlay" Blend Function working (Algorithm)?]

Well, yeah, true... anyone finding this topic over Google:

rhs is the pixel color of the top layer (the one set to overlay)

lhs is the blend color of the bottom layers

The Screen blend mode uses a totally different algorithm, and is not involved in the code I posted.

I was referring to the documentation, I haven't actually checked

So it takes the destination color in order to decide between Screen and Overlay and not the source color. Interesting.

Thank you very much. Very helpful.

I am trying to wrap my head around it, but I can't find a function that blends these colors

(122, 141, 153)

and

(0, 0, 0)

 

into this one

(0, 27, 51)

[.dds mipmap quality]

Hi,

 

when saving your images as .dds files you have different options to pre-create mipmaps.

What offers the best quality?

- Fant (What is "Fant"? - Fantastic? ^^)

- Supersampling

- Bilinear

- Bicubic

- Nearest

 

(I am using the German version. This is a rough translation - names might be different.)

 

Thank you very much

[Layer add transparent color]

The more I am thinking about it the more it makes sense. I now also noticed that the standard transparency color is white. That would cause a mess and is totally useless for many users

 

The alpha mask plugin works more or less like expected. The alpha values are not exactly correct (1, 3, 6 instead of 1, 2, 3 i.e.), however they are located in the right position.

 

I guess you will see me in the plugin section in a few days, again. Adding a new skinning mode.

 

Thank you very much for your help

[Layer add transparent color]

Hi,

 

I am using paint.net for a game project I am recently working on. For my textures I need

- a "light map/texture" (which stores only rgb values and alpha is zero)

- and a camouflage map (which stores only alpha values but rgb is zero)

 

Now I wanted to combine both layers to one layer. Sadly paint.net seems to ignore pixels with an alpha value of zero no matter which option I choose.

 

Little example, we have a 1x1 image. So one pixel.

> Layer 1: r = 1, g = 1, b = 1, a = 0

> Layer 2: r = 0, g = 0, b = 0, a = 1

 

When combining both layers (no matter what blending option used) the result is:

r = 0, g = 0, b = 0, a = 1 (Pixel from layer 2)

However, the result should be

r = 1, g = 1, b = 1, a = 1

 

How can I avoid that? I want both layers to be added together and alpha zero values not to be ignored. Is this a bug of the additive mode?

 

I need this because the alpha values are representing channels to indicate the graphics card which color to set for this pixel from 1 to 255 different colors. While the r, g, b colors are modifing those colors represented by the alpha values.

 

Thank you very much,

Icca
