We are pleased to announce the release of Spire.Presentation 8.10.2. This version supports getting location information of the text within shapes. Besides, it also supports getting the Ascent and Descent properties of the text within shapes and converting shapes to SVG format. What's more, it has fixed the issue that there was a blank space when opening SVG files in the browser after converting PPT to SVG. More details are listed below.
Here is a list of changes made in this release
| Category | ID | Description |
| New feature | SPIREPPT-2324 | Supported the functionality to obtain the text position information within a shape.
Presentation ppt = new Presentation();
ppt.LoadFromFile(inputFile);
StringBuilder sb = new StringBuilder();
ISlide slide = ppt.Slides[0];
for (int i = 0; i < slide.Shapes.Count; i++)
{
IShape shape = slide.Shapes[i];
if (shape is IAutoShape)
{
IAutoShape autoshape = slide.Shapes[i] as IAutoShape;
string text = autoshape.TextFrame.Text;
//obtain the text position information
PointF point = autoshape.TextFrame.GetTextLocation();
sb.AppendLine("Shape " + i + "：" + text + "\r\n" + "location：" + point.ToString());
}
}
File.AppendAllText(outputFile, sb.ToString());
ppt.Dispose();
