ColorsConverter

ColorsConverter is a class that contains all of the methods to convert colors.

a. RGBtoHEX

This function is available in version 1.5 and higher.

Compatibility

.NET Core 3.1	✔	✔
.NET Framework 4.5	✔	✔

This method allows you to convert a RGB color to a HEXColor. It's in:

LeoCorpLibrary.ColorsConverter.RGBtoHEX()

There is two variations of this method:

Variation 1 :

ColorsConverter.RGBtoHEX(Color color) {...}

Value	Argument	Description
Color	color	Color

Variation 2 :

ColorsConverter.RGBtoHEX(int red, int green, int blue) {...}

Value	Argument	Description	Example
int	red	Red	125
int	green	Green	45
int	blue	Blue	255

You can either use the System.Drawing.Color structure or put each RGB values.

Note

If, in the second variation of the method, you put an invalid number, the RGBInvalidValueException will be thrown.

Example of usage:

C#

// Example 1 :
HEXColor hexColor = ColorsConverter.RGBtoHEX(125, 45, 255);
Console.WriteLine(hexColor.Value); // Write value
// Example 2 :
Color color = Color.FromArgb(125, 45, 255)
HEXColor hexColor = ColorsConverter.RGBtoHEX(color);
Console.WriteLine(hexColor.Value); // Write value

VB

' Example 1 :
Dim hexColor As HEXColor = ColorsConverter.RGBtoHEX(125, 45, 255)
Console.WriteLine(hexColor.Value) ' Write value
' Example 2 :
Dim color As Color = Color.FromArgb(125, 45, 255)
HEXColor hexColor As HEXColor = ColorsConverter.RGBtoHEX(color)
Console.WriteLine(hexColor.Value) ' Write value

This method allows you to convert a HEX color to a RGB color. Returns a Color.

It's in:

LeoCorpLibrary.ColorsConverter.RGBtoHEX()

Here's this method's argument:

Value	Argument	Description
HEXColor	hexColor	HEX Color

Note

If you put an incorrect HEX value for hexColor, the HEXInvalidValueException will be thrown.

Example of usage:

C#

HEXColor hexColor = new HEXColor();
hexColor.Value = "ffffff";
Color color = ColorsConverter.HEXtoRGB(hexColor);

VB

Dim hexColor As HEXColor = New HEXColor()
hexColor.Value = "ffffff"
Dim color As Color = ColorsConverter.HEXtoRGB(hexColor)

This method allows you to convert a RGB color to a HSVColor.

It's in:

LeoCorpLibrary.ColorsConverter.RGBtoHSV()

There is two variations of this method:

Variation 1 :

ColorsConverter.RGBtoHSV(Color color) {...}

Value	Argument	Description
Color	color	Color

Variation 2 :

ColorsConverter.RGBtoHSV(int red, int green, int blue) {...}

Value	Argument	Description	Example
int	red	Red	125
int	green	Green	45
int	blue	Blue	255

You can either use the System.Drawing.Color structure or put each value individually.

Note

If in the second variation, you put an incorrect RGB color, the RGBInvalidValueException will be thrown.

Example of usage:

C#

// Example 1 :
HSVColor hsvColor = ColorsConverter.RGBtoHSV(125, 45, 255);
// Example 2 :
Color color = Color.FromArgb(125, 45, 255)
HSVColor hsvColor = ColorsConverter.RGBtoHSV(color);

VB

' Example 1 :
Dim hsvColor As HSVColor = ColorsConverter.RGBtoHSV(125, 45, 255)
' Example 2 :
Dim color As Color = Color.FromArgb(125, 45, 255)
HSVColor hsvColor As HSVColor = ColorsConverter.RGBtoHSV(color)

Dim hexColor As HEXColor = New HEXColor()
hexColor.Value = "ffffff"
HSVColor hsvColor = ColorsConverter.HEXtoHSV(hexColor)

HEXColor

The HEXColor structure allows to some methods to work correctly. It stocks the HEX value in a string.

To access the HEX value, you can use this example:

C#

HEXColor hexColor = ColorsConverter.RGBtoHEX(125, 12, 255);
Console.WriteLine(hexColor.Value);

VB

Dim hexColor As HEXColor = ColorsConverter.RGBtoHEX(125, 12, 255)
Console.WriteLine(hexColor.Value)

a. FromRGB

This function is available in version 1.5 and higher.

Compatibility

Frameworks	LeoCorpLibrary	LeoCorpLibrary.Core
.NET 6	✔	✔
.NET 5	✔	✔
.NET Core 3.1	✔	✔
.NET Framework 4.5	✔	✔

This method allows you to create a HEXColor form a RGB Color.

It's in:

LeoCorpLibrary.HEXColor.FromRGB()

There is two variation of this method:

Variation 1

HEXColor.FromRGB(Color color) {...}

Variation 2

HEXColor.FromRGB(int red, int green, int blue) {...}

You can either use the System.Drawing.Color structure or put each value individually.

Note

If in the second variation, you put an incorrect RGB color, the RGBInvalidValueException will be thrown.

Example of usage:

C#

// Example 1 :
Color color = Color.FromRGB(125, 12, 255);
HEXColor hexColor = HEXColor.FromRGB(color);
// Example 2 :
HEXColor hexColor = HEXColor.FromRGB(125, 12, 255);

VB

' Example 1 :
Dim color As Color = Color.FromRGB(125, 12, 255)
Dim hexColor As HEXColor = HEXColor.FromRGB(color)
' Example 2 :
Dim hexColor As HEXColor = HEXColor.FromRGB(125, 12, 255)

The HSVColor structure allows other methods to work properly. It stocks the value of an HSV color:

• Hue
• Saturation
• Value

Here's an example of code that you can use to get the different values:

C#

HSVColor hsvColor = ColorsConverter.RGBtoHSV(125, 12, 255);
Console.WriteLine(hsvColor.Hue.ToString() + "\n" + hsvColor.Saturation.ToString() + "\n" + hsvColor.Value.ToString());

VB

Dim hsvColor As HSVColor = ColorsConverter.RGBtoHSV(125, 12, 255)
Console.WriteLine(hsvColor.Hue.ToString() + vbNewLine + hsvColor.Saturation.ToString() + vbNewLine + hsvColor.Value.ToString())
