I am having a little graphics problem. Here is what I am trying to do: 1. Make a logo in Adobe or similar graphics program. Unless your logo is a solid square, you will need to open a alpha channel. There are 2 ways to do this.
The first method is
the easiest. If you have any other black in the logo, that'll disappear
using this method. The second method requires making two images,
both this same size. Use grey in areas that you want transparent
on the first image. Save the images as a targa (tga) or bitmap
(bmp). I am trying to do
the first method and saving it as a bmp file. The program does not seem
to accept TGA files whatever it says. The image attributes are Width
375 Height 288. The file that I am adding to the back background is:
http://www.huwnet.org.uk/images/shuwnet.jpg . The logo should go at the
bottom right. I have tried doing this the simple way in MSpaint but the
virtual dub program does not seem to like it. I have no advanced
graphics programes so if anyone could help I would be very grateful. |

I'm not sure what you're trying to do with the logo. Are you trying to make it semi-transparent? -------------

Adobe supports layers and opacity. First design the logo, then, if you want the background color to be part of the logo, use the alpha channel. ------------- Gone.. |

| OK! I don't have adobe :( Is there any other way of doing it? The logo I mentioned in my first post is going to be bottom right and the background when you make it black should not come out when it has been dubbed. |

I still don't know what you're trying to do with the logo other than to add an alpha channel to it. -------------

| Well I don't really understand myself. I am trying to add my logo to a film (.avi) using Virtual Dub. You create a black alpha chanel. You add the logo to the bottom right. Then when you add it the program will make the alpha channel transparent so you only see the logo. |

Don't know if AVI and alpha channel PNG's are combined that well... ------------- Gone.. |

| LOL! I am not mixing this myself. It goes through a free program called virtual dub. I would love to do this myself but I do not have adobe photoshop etc. |
