Your first code does not seem to have any problem. I have checked it with little additions to make it running.

-------------------------------------------------------

Presentation pres = new Presentation(new FileInputStream("c:\\source.ppt"));

Slide slide2=pres.getSlideByPosition(2);

long mstrId = slide2.getMasterId();

pres.getSlides().remove(slide2);

System.out.println("master id -- "+mstrId);

Slide mstrSld = pres.getSlideById(mstrId);

int lastSlidePos=pres.getSlides().getLastSlidePosition();

//slide.changeMaster(mstrSld, true);

for (int i = 1; i <= lastSlidePos; i++)

{

System.out.println("mstrSld -- "+mstrSld);

System.out.println("lasslidePos -- "+lastSlidePos);

System.out.println("i -- "+i);

Slide normSld = pres.getSlideByPosition(i);

normSld.changeMaster(mstrSld, true);

}

pres.write(new FileOutputStream("c:\\output.ppt"));

-------------------------------------------------------

Table height cannot be set after a minimum height of it has reached, this is because of font size inside table cells. For example, if font size of text inside the cell is 45, then row height cannot be decreased further after some specific height, to decrease it further, you need to set the font size to lesser than 45 say 30, 20.

You can try it in MS-PowerPoint.

Also, there are two other important APIs for setting height and width, they are Tables.setColumnWidth and Tables.setRowHeight.

Dear rmarala,

 

Thanks for considering Aspose.Slides

 

Please see the following example. I have also attached the output presentation generated by the code, please see it. The code is commented for your ease of understanding, if you still have question, please feel free to ask.

 

C#

//Create a presentation

Presentation pres = new Presentation();

 

//Get a slide

Slide sld = pres.GetSlideByPosition(1);

 

//Create 4 rectangles

Aspose.Slides.Rectangle rect1 = sld.Shapes.AddRectangle(760, 1050, 1730, 430);

Aspose.Slides.Rectangle rect2 = sld.Shapes.AddRectangle(760, 1830, 1730, 430);

Aspose.Slides.Rectangle rect3 = sld.Shapes.AddRectangle(3170, 1050, 1730, 430);

Aspose.Slides.Rectangle rect4 = sld.Shapes.AddRectangle(3170, 1830, 1730, 430);

 

//Give them background colors

rect1.FillFormat.Type = FillType.Solid;

rect1.FillFormat.ForeColor = Color.Aquamarine;

rect2.FillFormat.Type = FillType.Solid;

rect2.FillFormat.ForeColor = Color.Aquamarine;

rect3.FillFormat.Type = FillType.Solid;

rect3.FillFormat.ForeColor = Color.Bisque;

rect4.FillFormat.Type = FillType.Solid;

rect4.FillFormat.ForeColor = Color.Bisque;

 

//Assign center aligned bold text to first two rectangles

//1st

TextFrame tf = rect1.AddTextFrame(" ");

Paragraph para = tf.Paragraphs[0];

para.Alignment = TextAlignment.Center;

Portion port = tf.Paragraphs[0].Portions[0];

port.Text = "Column Name";

port.FontBold = true;

 

//2nd

tf = rect2.AddTextFrame(" ");

para = tf.Paragraphs[0];

para.Alignment = TextAlignment.Center;

port = tf.Paragraphs[0].Portions[0];

port.Text = "Column Name 2";

port.FontBold = true;

 

//Assign center aligned text to other two rectangles

//3rd

tf = rect3.AddTextFrame(" ");

para = tf.Paragraphs[0];

para.Alignment = TextAlignment.Center;

port = tf.Paragraphs[0].Portions[0];

port.Text = "Data";

 

//4th

tf = rect4.AddTextFrame(" ");

para = tf.Paragraphs[0];

para.Alignment = TextAlignment.Center;

port = tf.Paragraphs[0].Portions[0];

port.Text = "Data, Data";

 

pres.Write("c:\\outRectangles.ppt");
