Detailed Description
This interface attempts to provide an intuitive wrapper around "raw" unsigned integer colors.
An unsigned integer color is packed 32-bit value consisting of 4 pixel elements: RGBA. These elements are stored as written: RGBA, or, visually mapped as hex symbols: RRGGBBAA.
Function Documentation
◆ ColorGetFloat()
| float ColorGetFloat | ( | struct color | color, |
| char | component | ||
| ) |
Get the color component.
The component is returned as a float in the range [0.0,1.0]
- Parameters
-
color color object to read component 'r', 'g', 'b' or 'a' exclusively.
- Returns
- value of the color component
◆ ColorGetInt()
| unsigned int ColorGetInt | ( | struct color | color, |
| char | component | ||
| ) |
Get the color component.
The component is returned as the raw integer value, in the range [0,255]
- Parameters
-
color color object to read component 'r', 'g', 'b' or 'a' exclusively.
- Returns
- value of the color component
◆ ColorInitFloat()
| struct color ColorInitFloat | ( | float | r, |
| float | g, | ||
| float | b, | ||
| float | a | ||
| ) |
Initialize a new color with individual R, G, B, A components as floats.
- Parameters
-
r Red component from 0 to 1 g Green componenet from 0 to 1 b Blue component from 0 to 1 a Alpha component, from 0 to 1
- Returns
- resulting color object
◆ ColorSetFloat()
| void ColorSetFloat | ( | struct color * | color, |
| char | component, | ||
| float | value | ||
| ) |
Set the color component.
The value should be a float in the range [0.0,1.0]
- Parameters
-
color pointer to the color object to write component 'r', 'g', 'b' or 'a' exclusively. value value of the color component to set
◆ ColorSetInt()
| void ColorSetInt | ( | struct color * | color, |
| char | component, | ||
| unsigned int | value | ||
| ) |
Set the color component.
The value should be an integer in the range [0,255]
- Parameters
-
color pointer to the color object to write component 'r', 'g', 'b' or 'a' exclusively. value value of the color component to set
