DPI is not properly update to pdf output while converting tiff file as input

While trying to convert a sample tiff to pdf/a-2 the DPI does not set properly to the resulting PDF with the same value.

@ssamidis,

Can you please share that which API you are using along with used sample code, source file and generated output with us.

Hi mudassir.fayyaz

i am using aspose.pdf and aspose.imaging .

Code snippet:

public void Imagetif2() throws Exception {
java.io.FileInputStream fs;
com.aspose.imaging.Image image = com.aspose.imaging.Image.load(“file_example_TIFF_10MB.tiff”);
try {
//
System.out.println(" Image details before conversion ");
System.out.println(“image width:” +image.getWidth());
System.out.println(“image height:” + image.getHeight());
System.out.println(“image horizontal resolution:” + ((RasterImage) image).getHorizontalResolution());
System.out.println(“image vertical resolution:” + ((RasterImage) image).getVerticalResolution());
PdfOptions pdfOptions = new PdfOptions();
double width=image.getWidth()(72/((RasterImage)image).getHorizontalResolution());
double height=image.getHeight()
(72/((RasterImage)image).getVerticalResolution());
System.out.println(width);
System.out.println(height);
pdfOptions.setPageSize(new SizeF((int)width, (int)height));
image.save(“file_example_TIFF_10MB.pdf”, pdfOptions);
}
finally
{
image.close();
}

			com.aspose.pdf.Document document = new com.aspose.pdf.Document("file_example_TIFF_10MB.pdf");
			  ImagePlacementAbsorber abs = new ImagePlacementAbsorber();		
			  document.getPages().accept(abs);
			  
			  for (Object imagePlacement : abs.getImagePlacements())
			  {
			  	ImagePlacement placement = (ImagePlacement) imagePlacement;
	System.out.println(" Image details after conversion ");		  	

System.out.println(“image width:” + placement.getRectangle().getWidth());
System.out.println(“image height:” + placement.getRectangle().getHeight());
System.out.println(“image horizontal resolution:” + placement.getResolution().getX());
System.out.println(“image vertical resolution:” + placement.getResolution().getY());

			  }
	
}

output :

out put :

image width:1950
image height:1301
image horizontal resolution:72.00900268554688
image vertical resolution:72.00900268554688
