dna	If load a image like this: IMG_01=LoadImage("e:sep10.jpg") does BB use black as the default masking color? -=-=- DNA

CodersRule	IIRC you can use "MaskImage r,g,b" to change it.

Afr0	Yup. CodersRule is correct. Black is a stupid masking color. Who wants to make a game that doesn't use black? -=-=- Afr0 Games Project Dollhouse on Github - Please fork!

JL235	Afr0 Yup. CodersRule is correct. Black is a stupid masking color. Who wants to make a game that doesn't use black? Agreed, but it's also an easy one to remember. Although lots of people use pink these days, it's harder to remember it's rgb values of the top of your head.

waroffice	255,0,255 i think but its been a long day

CodersRule	I disagree that it's hard to remember. I don't have that much experience, and I c an mix lots of basic colours in my head. Magenta is one of the easiest ones. If you watch this video all the way through without interruptions, it'll glue to your head. Trust me. www.youtube.com/watch?v=VN4_Q7SBC7s

waroffice	I would rather watch that 10 min video than an entire game of football

steve_ancell	waroffice 255,0,255 i think but its been a long day That's Magenta apparently, but I suppose you could pass it off as Pink.

9572AD	I never had a problem using Black(0,0,0) as a masking color and using (1,1,1) for the color black. shrug -=-=- All the raw, animal magnetism of a rutabaga.

dna	If you do not match the color correctly then you will have artifacts in your image. -=-=- DNA

Jayenkai	Be wary of using 1,1,1.. On certain systems, in certain bitdepths, 1,1,1 becomes 0,0,0.. -=-=- ''Load, Next List!''

dna	That can't be right Jay. If so then it must happen at low bit resolutions. Numerically I cannot see that happening in 32 or 48 bit modes with all the colors. -=-=- DNA

Jayenkai	Blitz does 16 and 24 bit modes, and works on a multitude of DirectX7 graphics card, with a whole variety of quirks. Even if everything modern has swings and whistles, never forget that you "could" be running on your granny's PC. -=-=- ''Load, Next List!''

mindstorm8191	I have to agree with Jay. Not everyone has the latest and greatest PC hardware. Heck, some people are still running systems with Win98. If you exclude systems like that, you are shrinking your possible market. I honestly don't see why so many companies require the latest and greatest hardware out at the time, if it means most people will have to upgrade. But then, maybe people don't mind shelling out more money for hardware, to see the awesome effects the games can create. -=-=- Vesuvius web game

dna	When I run B2D to use the graphics, I run it in 32bit color mode. At that resolution 0,0,0 and 1,1,1 as a mask should be different, in the software. -=-=- DNA

JL235	Not everyone builds their games to run in 32-bit mode, so again I agree with Jay! Pretty certain you can also force applications to run in certain bit-modes, regardless of which one you've set. But IMHO this is only an issue with BB since it doesn't support transparency (full or bitmasked) in images. In anything else (like C#, Java or a wide range of C++ libraries) this is a non-issue.
