Hi, i get wrong visual representation fo gradient format in saved file even tho i set the same values as in original file, am thinking that here is a problem when i read gradientDirection, you can see the picture and code below.
pic: gradient.PNG (10.7 KB)
file: FillEffect.pptx.zip (20.7 KB)

String path = "FillEffect.pptx";

Presentation presentation = new Presentation(path);
ISlide slide = presentation.getSlides().get_Item(0);
AutoShape shape = (AutoShape) slide.getShapes().get_Item(0);
IParagraph paragraph = shape.getTextFrame().getParagraphs().get_Item(0);
IPortionCollection portions = paragraph.getPortions();
IPortion portion = portions.get_Item(0);

IGradientFormatEffectiveData gradientFormat = portion.createPortionFormatEffective().getFillFormat()
	.getGradientFormat();
int direction = gradientFormat.getGradientDirection();
byte gradientShape = gradientFormat.getGradientShape();
IGradientStopCollectionEffectiveData stops = gradientFormat.getGradientStops();

Portion newPortion = new Portion("Text2");
IFillFormat fillFormat = newPortion.getPortionFormat().getFillFormat();
fillFormat.setFillType(FillType.Gradient);
IGradientFormat newPortionGradient = fillFormat.getGradientFormat();
newPortionGradient.setGradientDirection(direction);
newPortionGradient.setGradientShape(gradientShape);
newPortionGradient.getGradientStops().add(stops.get_Item(0).getPosition(), stops.get_Item(0).getColor());
newPortionGradient.getGradientStops().add(stops.get_Item(1).getPosition(), stops.get_Item(1).getColor());


portions.clear();
portions.add(newPortion);
presentation.save("saved.pptx", SaveFormat.Pptx);

can you please check this out?
Thanks,
Zeljko.

Thank you @mudassir.fayyaz

Can you please help me figure out what direction correspond to what enum? Check the picture
picture: direction.png (8.7 KB)

|FromCenter|
|FromCorner1|
|FromCorner2|
|FromCorner3|
|FromCorner4|

From center is clear, but can you tell me what corners are 1 2 3 4?

Thanks,
Zeljko.

@Zeljko,

I suggest you to please try using below sample code with attached presentation for better elaboration of Gradient direction types.

public static void GetGradientDirections()
{
 String path="C:\\Aspose Data\\";
 
 Presentation pres=new Presentation(path+"Test Gradient Directions.pptx");
 ISlide slide=pres.getSlides().get_Item(0);
 
 for(int i=0;i<slide.getShapes().size();i++)
 {
     
  IAutoShape ashp=(IAutoShape)  slide.getShapes().get_Item(i);
  
  System.out.println("Shape Text: "+ashp.getTextFrame().getText());
        
  if(ashp.getFillFormat().getFillType()==FillType.Gradient)
  {
      
   System.out.println("Shape Gradient Direction: "+ashp.getFillFormat().getGradientFormat().getGradientDirection());
      
  }
     
 }
}

The following output shall be obtained:

Shape Text: From Bottom Right Corner
Shape Gradient Direction: 3 : FromCorner4
Shape Text: From Bottom Left Corner
Shape Gradient Direction: 1: FromCorner1
Shape Text: From Center
Shape Gradient Direction: 4 : FromCenter
Shape Text: From Top Right Corner
Shape Gradient Direction: 2: FromCorner3
Shape Text: From Top Left Corner
Shape Gradient Direction: 0: FromCorner1
