Detailed Description

Class representing a color.

Used for a variety of purposes in the engine.

Color values range from 0 to 255. To convert to a float-based color, use #Blam::Colors::D2DColorFromBlamColor.

Member Function Documentation

Equals()

bool BlamColor::Equals

(

BlamColor

other_color

)

Checks if this color is equal to another color.

This will check the r, g, b, and a values of the color against other_color. If all colors match, then this will return true. Otherwise, this will return false.

Parameters

other_color

- The color to check against.

Returns

true if all RBGA values are equal, otherwise returns false.

Here is the caller graph for this function:

FromString()

bool BlamColor::FromString

(

std::string

string

)

Attempts to set color information from a string.

String should be in either r,g,b or r,g,b,a format - the same format as is returned when using BlamColor::ToString();

Parameters

string

- The string to try to convert to a color.

Returns

true if the color was converted successfully, false if the conversion failed.

Here is the call graph for this function:

Here is the caller graph for this function:

FromVector3()

void BlamColor::FromVector3

(

BlamVector3

vector

)

Parses color information from a BlamVector3.

The XYZ values will be converted into RGB values, from 0 to 255. Any value which falls outside of this range will be clamped to the closest value - anything below 0 will become 0, and anything above 255 will be set to 255.

Parameters

vector

- The BlamVector3 to parse.

FromVector4()

void BlamColor::FromVector4

(

BlamVector4

vector

)

Parses color information from a BlamVector4.

The XYZW values will be converted into RGBA values, from 0 to 255. Any value which falls outside of this range will be clamped to the closest value - anything below 0 will become 0, and anything above 255 will be set to 255.

Parameters

vector

- The BlamVector4 to parse.

GetAlphaAsFloat()

float BlamColor::GetAlphaAsFloat

(

)

Gets the color's red value as a float, between 0 and 1.

Returns

The color's red value, converted to a float.

Here is the caller graph for this function:

GetBlueAsFloat()

float BlamColor::GetBlueAsFloat

(

)

Gets the color's red value as a float, between 0 and 1.

Returns

The color's red value, converted to a float.

Here is the caller graph for this function:

GetColorAsInt()

int BlamColor::GetColorAsInt

(

)

Gets the color's value as an integer.

This function will convert this color's value as an integer, in 0xAABBGGRR format. Each color is written in its hexadecimal format (ranging from 0x0 to 0xFF).

Returns

The color's value converted to an integer.

GetGreenAsFloat()

float BlamColor::GetGreenAsFloat

(

)

Gets the color's red value as a float, between 0 and 1.

Returns

The color's red value, converted to a float.

Here is the caller graph for this function:

GetRedAsFloat()

float BlamColor::GetRedAsFloat

(

)

Gets the color's red value as a float, between 0 and 1.

Returns

The color's red value, converted to a float.

Here is the caller graph for this function:

operator==()

bool BlamColor::operator==

(

const BlamColor &

other

)

Here is the call graph for this function:

ToString() [1/2]

std::string BlamColor::ToString

(

)

Converts the color value to a string.

Returns

The color information in r,g,b,a format.

Here is the call graph for this function:

Here is the caller graph for this function:

ToString() [2/2]

std::string BlamColor::ToString

(

std::string

format

)

Converts the color value to a string in the specified format.

The provided string can contain the following keys which will be replaced with the color values:

• {r} - Red
• {g} - Green
• {b} - Blue
• {a} - Alpha

Additionally, you can have a float representation of the value (instead of 0-255) by adding >f inside a color placeholder. Example: {r} of 255 would be 1.0 with {r>f}.

Parameters

format

- The string containing any color placeholders to be replaced.

Returns

The string with the color placeholders replaced.

Here is the call graph for this function:

ToStringForCSS()

std::string BlamColor::ToStringForCSS

(

)

Converts the color to a string that can be used with CSS.

Returns

The color represented as a string, in the following format: rgba(r,g,b,a)

Here is the call graph for this function:

ToVector3()

BlamVector3 BlamColor::ToVector3

(

)

Converts the color into a BlamVector3.

RGB will be converted into floats, and then set to the XYZ values of the vector. This can be used in cases (such as imgui) where we need to read full color information as a floating-point vector.

Returns

The color information, represented as a BlamVector3.

Here is the call graph for this function:

ToVector4()

BlamVector4 BlamColor::ToVector4

(

)

Converts the color into a BlamVector4.

RGBA will be converted into floats, and then set to the XYZW values of the vector. This can be used in cases (such as imgui) where we need to read full color information as a floating-point vector.

Returns

The color information, represented as a BlamVector4.

Here is the call graph for this function:
