Well I have an assignment for General Programming for school. Our assignment is to make a game. I've thought up a game called target practice where you use angles to shoot the target that pops up in random spots on the form. But it seems that I've got stuck way earlyier then I expected to.

If you look at the screenshot the picture of the man ("Kevin Rudd LOL") is transparent but the problem is the bits that are transparent go right back to the grey form. When I want them to go to the picture box behind kevin rudd. I hope that makes sense. You'll understand when you see the screenshot.

I forgot to mention that grey is the transparent key on the form.

Please shed some knowledge on this subject

short answer, vb says no

i have tested this before, it doesnt like the fact that there are controls underneath, if its set to transperant it just uses the form colour, so id say you need to photoshop that sucker

VB hates alpha channels

[dnsi0]

that's why you should use directdraw or direct3d with vb. It runs pretty well (surprisingly). (You should use Direct3D since directdraw doesn't support alpha channels or at least I can't find them...)

So what would be the most logical way around this. It's really difficult to get the gradient on the target to match the gradient on the background image so photoshop isn't really an option. Some snippets would be really helpful but I know that's a lot to ask.

EDIT: I've been doing some research I found this.

I know that C# has a class "System.Drawing.Drawing2D.ColorBlend".

I doubt it will be of any use though. :\

Best thing to do is use a tranparent PNG. Load the image up in Photoshop, select the grey background section, then delete it. It'll show up as transparency. Go to File -> Save As, set the file type to PNG. Make sure that you enable transparency, leave interlacing as none.

Make sure you set the background colour of the picture box to Transparent.

Dude the image isn't grey. The form colour is grey. The image already is transparent.

Using the .NET drawing class is probably the smartest way in this case... but I've never used GDI+ so I'm not sure if there's a nice, native way of ignoring a certain color.

There seems to be a method for locking the bits to the image though. I suppose you can manually iterate through each pixel and ignore what should be transparent, but this may be overkill and out of your scope.



Looking through MSDN though it looks like you should be able to just create a Bitmap object, set the PixelFormat to 32 ARGB, set the transparency key with the MakeTransparent method and draw it.

I'll look into that. Even though almost everything is out of my scope. I'm not a big fan of vb.net. But yeah I'll keep researching. Any snippets that you can give me would be nice .
