Convert IColor to Drawing.Color

[lidds]

Please could you help as I cannot seem to figure this out and have spent a good amount of time searching the forum.

All I want to do is convert an IColor to the equivalent Drawing.Color. e.g.

Code: Select all

Dim annotColor As Color =  Color.FromArgb(annot.Data.Color.RGB)

Thanks

Hi, lidds

Is this intended to be in the SDK forums? you seem to have posted on the End user Forums instead. Please let me know which SDK this is pertaining to and I can move the topic to the appropriate forum for you.

Kind regards,

Hi Daniel,

Yes my mistake it is meant to be in the PDF Xchange Editor SDK forum. If you could move it that would be great.

Thanks

Hello Simon,

Please check the CoreAPIDemo application for the Annotations samples - there are many places that the color is being set:

Alex,

I don't want to set the colour of the annotation, I know how to do this. I want to get the colour of the annotation as Drawing.Color

Thanks

Hello lidds,

We have this method in the FullDemo application:

Code: Select all

public static Color rgb2clr(int c)
{
	int r = c & 0x000000FF;
	int g = (c & 0x0000FF00) >> 8;
	int b = (c & 0x00FF0000) >> 16;
	return Color.FromArgb(r, g, b);
}

Cheers,
Alex

Hi Alex,

Sorry to bring this forum back up again, however I'm not sure if I am passing the correct value to get converted (I am using the following value annot.Data.Color.RGB which is returning a value example of 4282400768) as I get the following error:

I'm sure I am doing something stupid, but am unsure as to how to convert the color and what value to use?

Thanks

Hello lidds,

The Color should be in the 0XFFAABBCC format. First one is alpha (that is not used), then all of the other components based on code.

Cheers,
Alex

Hi Alex,

Thanks for the information however what property do I get that colour value from on the annotation item as there is no property that returns that value, see screen shot:

Sorry for asking what might be a simple question

Thanks

Don't worry Alex I figured it out, thanks for your help.

Code: Select all

Public Function IColorToColor(ByVal IColourRGB As UInteger) As Color
        Dim hexColour As String = Hex(IColourRGB)
        hexColour = hexColour.Substring(hexColour.Length - 6)

        Dim r As String = hexColour.Substring(4, 2)
        Dim g As String = hexColour.Substring(2, 2)
        Dim b As String = hexColour.Substring(0, 2)

        Return ColorTranslator.FromHtml("#" & r & g & b)
    End Function
