hi,
I’m trying to find out how to get the text size of a portion in the paragraph and how to get the background color and font color of a portion. Can you show me please? I need to gather information about text font color and background color to make sure that the text is more visible. For example, a purple font with black background is hard to read. I need a way to identify these. Thank you in advance for your help.

Hi,

Here is the complete code example for setting text formatting properties:

Presentation pres = new Presentation();

Slide sld = pres.GetSlideByPosition(1);

Aspose.Slides.Rectangle rect= sld.Shapes.AddRectangle(100, 100, 500, 500);

TextFrame tf= rect.AddTextFrame("Hello");

tf.Paragraphs[0].Portions[0].FontColor = Color.Green;

tf.Paragraphs[0].Portions[0].FontHeight = 15;

tf.FillFormat.Type = FillType.Solid;

tf.FillFormat.BackColor = Color.Black;

tf.FitShapeToText = true;

pres.Fonts[tf.Paragraphs[0].Portions[0].FontIndex].FontName = "Times New Roman";

pres.Write("d:\\ppt\\test\\fontPPT.ppt");

Hi,

Here is the sample code to find text from PPTX and set its formatting attributes:

PresentationEx pres = new PresentationEx("tst.pptx");

TextFrameEx[] tf = PresentationScanner.GetAllTextFrames(pres, false);

for (int i = 0; i < tf.Length; i++)

foreach (ParagraphEx para in tf[i].Paragraphs)

foreach (PortionEx port in para.Portions)

{

FontDataEx fnt = new FontDataEx("Times New Roman");

port.RawFontBold = NullableBool.True;

port.RawFontUnderline = TextUnderlineTypeEx.Double;

port.RawLatinFont = fnt;

port.RawFontHeight = 40;

}

pres.Write("tst1.pptx");
