GETPIXEL()

[WPShadow]

Hi!

Wie genau kann man den einzelnen Farbwert bei Getpixel raus bekommen? Die Werte die ich bekomme sind vermutlich HEX, brauchen w?rde ich widerum RGB - Werte von 0 - 255, um einzelne Werte zu errechnen...

Gru?

SuFu:

Code von Quentin:

Code (glbasic) Select Expand

  color = RGB(250, 13, 56)
  red = bAND(color, 255)
  green = bAND(color / 256, 255)
  blue = bAND(color / 256 * 256), 255)

Hey there WP
The getpixel command is sensitive..

Just a couple tips from a little experience with this command:

Getpixel has a margin of error, if your computer or any computer your program is installed on, has a video card using "antialiasing"(this is very common for game players to use for smoothness of colors).
So to solve this you can do 2 things:
1. If you need it to run dynamically(realtime) then turn off antialiasing...and make a help file for your program to tell your users to do that too.
2. use getpixel(again make sure AA is off) in the development phase of your software, convert the data into data files(you may need to encrypt them), this will allow you to develop, and not need to worry about your users needing to shut off antialiasing.

But not as professional as ATI do!

That is a tile demo, why do you need getpixel for this?

Need a little time to show you the first demo!
