A file with the .ODT file extension is an OpenDocument Text document file. These files are most often created by the free OpenOffice Writer word processor program. ODT files are similar to the popular DOCX file format used with Microsoft Word. Both of the two file types can hold things like text, images, objects, and styles.
However, when you open an ODT document in Microsoft Word, the formatting of the ODT document may differ as a result of the two programs not sharing the same features. When converting ODT to DOCX or vice versa, the data and content will be converted successfully, but may not including the original formatting.
Following code snippets introduce how to convert ODT to DOC or DOCX and vice versa using Spire.Doc.
ODT to DOCX
To convert ODT to DOC, change the file extension and file format to .Doc in SaveToFile method.
using Spire.Doc;
namespace ODTtoDOCX
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
doc.LoadFromFile("SampleODTFile.odt");
doc.SaveToFile("output.docx", FileFormat.Docx)
}
}
}
Imports Spire.Doc
Namespace ODTtoDOCX
Class Program
Private Shared Sub Main(args As String())
Dim doc As New Document()
doc.LoadFromFile("SampleODTFile.odt")
doc.SaveToFile("output.docx", FileFormat.Docx)
End Sub
End Class
End Namespace
DOCX to ODT
To convert Doc to ODT, load a .Doc file format document when loading the source file.
using Spire.Doc;
namespace DOCXtoODT
{
class Program
{
static void Main(string[] args)
{
Document doc = new Document();
doc.LoadFromFile("SampleODTFile.odt");
doc.SaveToFile("output.docx", FileFormat.Docx);
}
}
}
Imports Spire.Doc
Namespace DOCXtoODT
Class Program
Private Shared Sub Main(args As String())
Dim doc As New Document()
doc.LoadFromFile("SampleODTFile.odt")
doc.SaveToFile("output.docx", FileFormat.Docx)
End Sub
End Class
End Namespace
A Scatter (X Y) Chart has two value axes – X value axis and Y value axis. It combines X and Y values into single data points and shows them in irregular intervals, or clusters. This article will show you how to create scatter chart in PowerPoint using Spire.Presentation with C#.
Step 1: Create a Presentation object.
Presentation presentation = new Presentation();
Step 2: Add a "Scatter with Smooth Lines and Markers" chart to the first slide, and set the chart title.
IChart chart = presentation.Slides[0].Shapes.AppendChart(ChartType.ScatterSmoothLinesAndMarkers, new RectangleF(40, 80, 550, 320), false); chart.ChartTitle.TextProperties.Text = "Scatter Chart"; chart.ChartTitle.TextProperties.IsCentered = true; chart.ChartTitle.Height = 20; chart.HasTitle = true;
Step 3: Write data to the chart data.
Double[] xdata = new Double[] { 1.0, 2.4, 5.0, 8.9 };
Double[] ydata = new Double[] { 5.3, 15.2, 6.7, 8 };
chart.ChartData[0, 0].Text = "X-Values";
chart.ChartData[0, 1].Text = "Y-Values";
for (Int32 i = 0; i < xdata.Length; ++i)
{
chart.ChartData[i + 1, 0].Value = xdata[i];
chart.ChartData[i + 1, 1].Value = ydata[i];
}
Step 4: Set up the data source of the X values, the Y values, and the series label.
chart.Series.SeriesLabel = chart.ChartData["B1", "B1"]; chart.Series[0].XValues= chart.ChartData["A2", "A5"]; chart.Series[0].YValues = chart.ChartData["B2", "B5"];
Step 5: Add and display the data labels in the chart.
for (int i = 0; i < 4; i++)
{
ChartDataLabel dataLabel = chart.Series[0].DataLabels.Add();
dataLabel.LabelValueVisible = true;
}
Step 6: Set the axis titles.
chart.PrimaryValueAxis.HasTitle = true; chart.PrimaryValueAxis.Title.TextProperties.Text = "X-Axis Title"; chart.SecondaryValueAxis.HasTitle = true; chart.SecondaryValueAxis.Title.TextProperties.Text = "Y-Axis Title";
Step 7: Format the gridlines.
chart.SecondaryValueAxis.MajorGridTextLines.FillType = FillFormatType.Solid; chart.SecondaryValueAxis.MajorGridTextLines.Style = TextLineStyle.ThinThin; chart.SecondaryValueAxis.MajorGridTextLines.SolidFillColor.Color = Color.Gray; chart.PrimaryValueAxis.MajorGridTextLines.FillType = FillFormatType.None;
Step 8: Format the outline.
chart.Series[0].Line.FillType = FillFormatType.Solid; chart.Series[0].Line.Width = 0.1f; chart.Series[0].Line.SolidFillColor.Color = Color.RoyalBlue;
Step 9: Save the file.
presentation.SaveToFile("ScatterChart.pptx", FileFormat.Pptx2010);

C# Set animation effect for the animate text on the presentation slides
2018-01-24 08:24:09 Written by KoohjiWe have already demonstrated how to set the animations on shapes in PowerPoint. Now Spire.Presentation starts to support set the Animation Effect for the type and time of the animate text. This article will show you how to use IterateType property and IterateTimeValue property for animation Effect to set the type and time of animate text in C#.
Firstly, view the original sample document with animate text effect with "All at once".
Step 1: Create a presentation instance and load the sample document from file.
Presentation ppt = new Presentation();
ppt.LoadFromFile("Sample.pptx",FileFormat.Pptx2010);
Step 2: Set the AnimateType as Letter.
ppt.Slides[0].Timeline.MainSequence[0].IterateType = Spire.Presentation.Drawing.TimeLine.AnimateType.Letter;
Step 3: Set the IterateTimeValue for the animate text.
ppt.Slides[0].Timeline.MainSequence[0].IterateTimeValue = 10;
Step 4: Save the document to file.
ppt.SaveToFile("Result.pptx", FileFormat.Pptx2010);
Effective screenshot of the animation effect for the animate text effect with "by Letter".
