Edit Text and Image Properties ​

ComPDFKit supports to modify the properties of text and images. To configure text and image properties, you can utilize the PDFEditActiveHandler event of CPDFViewer.

Edit Text Properties ​

ComPDFKit supports modifying text properties, such as text font size, name, color, alignment, italics, bold, transparency, etc.

This example shows how to set text to 12pt, red, and bold:

C#
viewer.PDFEditActiveHandler += Viewer_PDFEditActiveHandler;
private void Viewer_PDFEditActiveHandler(object sender, PDFEditEvent e)
{
    // Text properties
    if (e.EditType == CPDFEditType.EditText)
    {
        e.FontColor = Colors.Red;
        e.FontSize = 12;
        e.TextAlign = TextAlignType.AlignJustify;
        e.FontWeight = FontWeights.Bold;
        e.FontStyle = FontStyles.Italic;
        e.FontFamily = new FontFamily("TimesNewRoman");
        e.Transparency = 255;
        e.UpdatePDFEditByEventArgs();
    }
}

Edit Image Properties ​

ComPDFKit supports modifying image properties, such as rotating, cropping, mirroring, and setting transparency.

This example shows how to rotate an image and set it to semi-transparent:

C#
viewer.PDFEditActiveHandler += Viewer_PDFEditActiveHandler;
private void Viewer_PDFEditActiveHandler(object sender, PDFEditEvent e)
{
    //Image properties.
    if (e.EditType == CPDFEditType.EditImage)
    {
        e.VerticalMirror = true;
        e.HorizontalMirror = true;
        e.ClipImage = true;
        e.Rotate = 90;
        e.ReplaceImagePath = "***";
        e.Transparency = 255;
        e.UpdatePDFEditByEventArgs();
    }
}
