ColorRecHelper

Jerry Dodge's ColorRecord Helper for easy manipulating of Web Colors, Delphi Colors. XE5 Example App, Use-cases, and bad but useful (to me) enhancements.

Notes:

• Delphi Hex order is not the same as HTML Hex order
• examples:
• HTML Hex Color (Web Development) = #FFFFFF
• HTML Hex Color Custom Constant (Inside Delphi, if we want to use) = $FFBF00 (Amber,#FFBF00 in web development)
• Delphi Hex Color = $F0CAA6
• Delphi TColor = clMoneyGreen
• R,G,B of a Color (0..255,0..255,0.255)
• H,S,V of a Color (0..1, 0..1, 0..1 )
• H(degrees),S,V of a Color (0..360, 0..1, 0..1 )

Some use cases:

Natural String to color from editor based input (Goodie Part)

Trick to make tints of color #Access as HSV and play with Value/Brightness(V field) #Use the final result as required.

procedure TForm1.btnHexDemosViaRecordHelperClick(Sender: TObject);
var
 col1 : TColorRec;
 myHTMLColor : TNaturalColorHTMLHex;
begin
    //Delphi to Hex
    col1 := clNone;
    edtHexDelphi.Text := col1.GetDelphiHexWithoutDollar;
    shp2.Brush.Color := col1;
    edtDelphiRGB.Text := IntToStr(col1.FRed) + ', '+IntToStr(col1.FGreen) + ', '+IntToStr(col1.FBlue);

//Delphi Hex to TColor
col1.SetDelphiHexWithoutDollarInput(edtHexDelphi.Text);
shp2.Brush.Color := col1;
edtDelphiRGB.Text := IntToStr(col1.FRed) + ', '+IntToStr(col1.FGreen) + ', '+IntToStr(col1.FBlue);

//Delphi Hex to HTML Hex
col1.SetDelphiHexWithoutDollarInput(edtHexDelphi.Text);
shp2.Brush.Color := col1;
edtHexHTML.Text := col1.GetHTMLHexWithoutHash;

//HTML Hex to TColor
col1.SetHTMLHexWithoutHashInput(edtHexHTML.Text);
shp2.Brush.Color := col1;

col1.SetHTMLHexWithDollar($FFD700);
myHTMLColor := TNaturalColorHTMLHex.green;
col1.SetHTMLHexWithDollar(Ord(myHTMLColor));

col1.SetColorFromNaturalString('rose');
shp2.Brush.Color := col1;

end;
