PDF Background Color from Hex

[Nils Steinle]

Hello,

i'm trying to change the Background-Color from the PDF i generate.
I need to use HEX Values, not the Syncfusion.Drawing Colors.

I'm trying to use the ColorTranslator.Fromhtml:

Data from Syncfusion.Drawing.ColorTranslator.FromHtml("#000000"):

With FromHtml(Hex) the Background is still white.

----------------------------------

This is working:

Data from Syncfusion.Drawing.Color.DodgerBlue:

With DodgerBlue the PDF Background is Blue and works.

What can i do to use Hex values for the PDF Background?
(I'm using the Webkit Engine)

Thanks for help,

Nils

Hi Nils,  

  

Sorry for the inconvenience caused.  

  

We have checked the reported issue with “White background color while using color from hex value” . We do not have complete support to set background color using hex values. It is returns the RGB value of the hex values. Generally, the RGB can be different combination and each has some color name. Syncfusion.Drawing cannot provide names for these combinations to set background color. We can use color name directly to set the background color using Syncfusion.Drawing.Color property. 

 

Please let us know if you need any further assistance on this.

Hello,

so there is no way to take the color out of the colorpicker?

<SfColorPicker Mode="ColorPickerMode.Palette" ShowButtons="false" ModeSwitcher="false" ValueChange="@ColorPicked"></SfColorPicker>

And use it as PDF Background? :/

 

that would be very annoying. is there an alternative? or do you have another idea?

Regards,

Nils

I've built my own color-picker with the drawing.colors now, so this topic is solved.

unfortunately the colors are not as nice and flexible as the ones from the hex-palette and the hex-picker is unusable. it would be nice if the translation from hex to syncfusion.color is integrated sometime in the future.

thanks for your assist

Hi Nils, 

 

Thank you for your patience.

 

We have checked the possibilities on our end. Unfortunately, we can’t implement it in our control. Because comparing the RGB values for known colors takes time and it will result in performance degradation. However, we have found a workaround using System.Drawing which can be implemented on your sample level. It will provide known color names while getting color using HTML Hex values.  

Code snippet: 

Syncfusion.Drawing.Color color = Syncfusion.Drawing.ColorTranslator.FromHtml("#1e90ff"); 

 

foreach (string name in Enum.GetNames(typeof(System.Drawing.KnownColor))) 

{ 

   if (color.ToArgb() == Syncfusion.Drawing.Color.FromName(name).ToArgb()) 

   { 

      Console.WriteLine(name); 

      settings.BackgroundColor = Syncfusion.Drawing.Color.FromName(name); 

      break; 

   } 

} 

 

Please let us know if you need any further assistance with this.
