Thank you, I tested with, but it did not added the “¤” signs, please check the source file is the:
test.pptx
the final file is:
text_replace.pptxtext_replace.zip (52.7 KB)
I suggest you to please try using following sample code on your end.
public static void TestReplaceText()
{
String path = @"C:\Aspose Data\text_replace\";
Presentation pres = new Presentation(path + "test.pptx");
for (int i = 0; i < pres.Slides.Count; i++)
{
ISlide slide = pres.Slides[i];
foreach (IShape shape in slide.Shapes)
{
IParagraphCollection paragraphCollection = ((IAutoShape)shape).TextFrame.Paragraphs;
foreach (IParagraph para in paragraphCollection)
{
IPortion first = null;
IPortion last = null;
IPortionCollection portions = para.Portions;
for (int p = 0; p < portions.Count; p++)
{
IPortion portion = portions[p];
IPortionFormat portFormat = portion.PortionFormat;
// IPortionFormatEffectiveData portFormat = portion.CreatePortionFormatEffective();
//if (portFormat.FillFormat.SolidFillColor.Color == Color.Black)
if (portFormat.FillFormat.SolidFillColor.Color.R==0 && portFormat.FillFormat.SolidFillColor.Color.G==0
&&portFormat.FillFormat.SolidFillColor.Color.B==0)
{
if (first == null)
{
first = portion;
}
last = portion;
}
if (((portFormat.FillFormat.SolidFillColor.Color.R ==255
// if (((portFormat.FillFormat.SolidFillColor == Color.Red
|| (p == portions.Count - 1)) && first != null && last != null))
{
if (first == last)
{
String portionText = first.Text;
first.Text = "¤" + portionText + "¤";
}
else
{
String firstPortionText = first.Text;
String lastPortionText = last.Text;
first.Text = "¤" + firstPortionText;
last.Text = lastPortionText + "¤";
}
first = null;
last = null;
}
}
}
}
}
pres.Save(path + "text_replace2.pptx", Aspose.Slides.Export.SaveFormat.Pptx);
}Hello,
With the test file, it was worked amazingly, with a complicated file I got an invalid cast exception, as unfortnately I am not an expert of this API, I can’t figure it out.
Can you please check with the attached file.new_test.zip (3.8 MB)
The exception that you have received is owing accessing paragraph collection from a PictureFrame. Please use following amended sample code.
public static void TestReplaceText()
{
String path = @"C:\Aspose Data\text_replace\";
path = @"C:\Aspose Data\new_test\";
Presentation pres = new Presentation(path + "new_test.pptx");

{
ISlide slide = pres.Slides[i];
foreach (IShape shape in slide.Shapes)
{
if (shape is IAutoShape)
{
IParagraphCollection paragraphCollection = ((IAutoShape)shape).TextFrame.Paragraphs;
foreach (IParagraph para in paragraphCollection)
{
IPortion first = null;
IPortion last = null;
IPortionCollection portions = para.Portions;
for (int p = 0; p < portions.Count; p++)
