Hello All, What ever the color

Hello All, What ever the color

Hello All, What ever the color

Hello All,
What ever the color code i am using for the sub string in a drawing text, it is changing to black color. Can any one help me in solving this. The below is the code. Thanks in advance.

DrawingText.setparameteronsubstring catcolor, starting position, length, ival


RE: Hello All, What ever the color

Which means that you fail to set catcolor in a correct way.
CATIA expects it to be encoded in RGBA:


catcolor = 255 * 255 * 255 * red + 255 * 255 * green + 255 * blue + alpha 

RE: Hello All, What ever the color

Hello Little,
Thanks for the answer. I have taken the color codes from google. I have given 32 and 5 also. For both the values it is changing to Black only. Please help me.\


RE: Hello All, What ever the color

Use this functions to convert between RGBA and Long:


' Courtesy of Little Cthulhu, 2020
Function RGBAtoLong(r, g, b, a)
    Dim lColorRGBA
    If (r >= 128) Then
        ' first bit is not 0, resulting long is negative
        lColorRGBA = &H81000000 + (r - 129) * &H1000000 + g * &H10000 + b * &H100 + a
        ' first bit is 0, resulting long is positive
        lColorRGBA = r * &H1000000 + g * &H10000 + b * &H100 + a
    End If
    RGBAtoLong = lColorRGBA
End Function

Function LongToRGBA(lngColor) ' Array[4]
    Dim lColor: lColor = Abs(lngColor)
    If lngColor < 0 Then
        lColor = lColor - 1
    End If
    ReDim rgba(3)
    Dim i: For i = 0 To 3
        rgba(3 - i) = lColor Mod 256
        lColor = (lColor - rgba(3 - i)) / 256
        If lngColor < 0 Then
            rgba(3 - i) = 255 - rgba(3 - i)
        End If
    LongToRGBA = rgba
End Function

eBook - Functional Prototyping Using Metal 3D Printing
Functional prototypes are a key step in product development – they give engineers a chance to test new ideas and designs while also revealing how the product will stand up to real-world use. And when it comes to functional prototypes, 3D printing is rewriting the rules of what’s possible. Download Now
