problem with mask and pixamp
BlitzMax Forums/BlitzMax Beginners Area/problem with mask and pixamp
| ||
It's write in doc that the Mask is 8 bits channel, so 256 level of grey, but when i try to copy somethink inside or just draw stuff in, my mask is or black or white. How can i put 8 bits of information inside it? |

The definition of mask is either draw the pixel or don't. Alpha blend mode uses the full 8 bits to blend the pixel so try: SetBlend ALPHABLEND to draw with alphablending instead. |

Also I think any alpha value over 0.5 intensity (ie 128?) means draw the pixel, while anything below that means make it transparent. |

I was talking about Pixmap, sorry. So, i don't want to use SetBlend coz i want precisely to made my own blending mode. |
