Design of rectangles using C#

[rokaf]

Greetings!

I have to create rectangle using C#, can anyone help me with this this?

Code for currently rectangle:

Code: Select all

 public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, int paragraphs)
        {
            var cd = dataLabels.Add();

            cd.LabelValueVisible = true;
            cd.TextFrame.Paragraphs.Clear();
            for (int i = 0; i < paragraphs; i++)
            {
                cd.TextFrame.Paragraphs.Append(CreateParagraph());
            }

            return cd;
        }

        public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, string text)
        {
            var cd = dataLabels.Add(1);
            cd.TextFrame.Paragraphs[0].Text = text;

            return cd;
        }

        public static TextParagraph CreateParagraph()
        {
            var paragraph = new TextParagraph
            {
                Alignment = TextAlignmentType.Left,
                Text = string.Empty
            };
            paragraph.FirstTextRange.Format.FontHeight = 8;
            return paragraph;
        }

Dear rokaf,

Thanks for your inquiry.
According to your picture, I guess below two requirements are what you want.
1. Change the color of shape line to black, if so, please refer to following code.

Code: Select all

            var cd = dataLabels.Add();           
            cd.LabelValueVisible = true;
            //change the line color
            cd.Line.FillFormat.FillType = FillFormatType.Solid;
            cd.Line.FillFormat.SolidFillColor.Color = Color.Black;
           //your code...

2. Do you want to change the data label shape as below ?

You could provide us with the expected MS PPT file for further investigation.

Yes, I need rectangle with rounded corners

Dear rokaf,

Thanks for your response.
Sorry that Spire.Presentation doesn't support that feature at present. We will consider adding it in our future upgrade. We will keep you informed once there is any update.

Okay, thank you.
How can I add transparency to my rectangle?

[Betsy.jiang]

Dear rokaf,

Thanks for your information again.
There is no direct way to set the transparency at present, yet there is a workaround that is using alpha when filling the color. Sample code for your reference:

Code: Select all

            cd.Fill.FillType = FillFormatType.Solid;
            cd.Fill.SolidColor.Color = Color.FromArgb(0x60,Color.Red);

I have one more question: how can I add outline shadow to my rectangle?

Here is how my code looks like:

Code: Select all

        public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, int paragraphs)
        {
            var cd = dataLabels.Add();

            cd.LabelValueVisible = true;
            cd.TextFrame.Paragraphs.Clear();

            cd.Fill.FillType = FillFormatType.Solid;
            cd.Fill.SolidColor.Color = Color.FromArgb(0x99, Color.White);
           

            cd.Line.FillFormat.FillType = FillFormatType.Solid;
            cd.Line.FillFormat.SolidFillColor.Color = Color.Black;
            for (int i = 0; i < paragraphs; i++)
            {
                cd.TextFrame.Paragraphs.Append(CreateParagraph());
            }

            return cd;
        }

Can I create it if I'll use the following algorithm?

Code: Select all

IAutoShape shape = slide.Shapes.AppendShape(ShapeType.Rectangle, new RectangleF(50, 100, 100, 50));

shape.ShapeStyle.LineColor.Color = Color.Red;

//Effect
PresetShadow shadow = new PresetShadow();
shadow.Preset = PresetShadowValue.FrontRightPerspective;
shadow.Distance = 10.0;
shadow.Direction = 225.0f;
shape.EffectDag.PresetShadowEffect = shadow;


Can I merge it with my code structure?

Code: Select all

  public static ChartDataLabel Add(this ChartDataLabelCollection dataLabels, int paragraphs)
        {
            var cd = dataLabels.Add();

            cd.LabelValueVisible = true;
            cd.TextFrame.Paragraphs.Clear();

           
            cd.Fill.FillType = FillFormatType.Solid;
            cd.Fill.SolidColor.Color = Color.FromArgb(0x99, Color.WhiteSmoke);
     

            cd.Line.FillFormat.FillType = FillFormatType.Solid;
            cd.Line.FillFormat.SolidFillColor.Color = Color.Black;


            cd.TextFrame.Paragraphs.Append(CreateHeader());

            for (int i = 1; i < paragraphs; i++)
            {
                cd.TextFrame.Paragraphs.Append(CreateParagraph());
            }

            return cd;
        }

Dear rokaf,

Thanks for your inquiry.
After an in-depth investigation, we found a way to set the shadow of the data lable.
Please refer to the below code.

Code: Select all

cd.Effect.PresetShadowEffect = new PresetShadow();
cd.Effect.PresetShadowEffect.ColorFormat.Color = Color.Red;           
cd.Effect.PresetShadowEffect.Distance = 10.0f;
cd.Effect.PresetShadowEffect.Direction = 225.0f;

Thank you!
But I still didn't get how to set shadow size, can you help me?
I need to create this shadow using code(check shadow.png).
For now I've successfully created shadow with needed blur and transparency:

Code: Select all

            cd.Effect.OuterShadowEffect = new OuterShadowEffect();
            cd.Effect.OuterShadowEffect.ColorFormat.Color = Color.FromArgb(99,154,154,154);
            cd.Effect.OuterShadowEffect.BlurRadius = 5;

Dear rokaf,

Thanks for your inquiry.
Please refer to the below code to set the size of shadow.

Code: Select all

cd.Effect.OuterShadowEffect.HorizontalScalingFactor = 102f;
cd.Effect.OuterShadowEffect.VerticalScalingFactor = 102f;

How can I create point like this?(point jpg)

And maybe there are any extra ways to make datalabel look like rectangle with rounded corners? For example using picture or something? (shape.jpg)
