Hello.

I am using Aspose.Pdf for Java and encountered a problem when I added a PNG image with a transparent background to pdf. The background turned into black color. I searched the forum and found someone had the same problem with Aspose.Pdf for .NET in Aug 2008 and Aspose support team gave him a solution. But for Aspose.Pdf for Java. Do you have a solution for this scenario?

By the way, here is your solution for .NET.

I’m using Aspose PDF 3.0.1 and still see this issue.

Code:
Section section = pdf.getSections().add();

                    Image image = new aspose.pdf.Image(section);
                    image.getImageInfo().setImageStream(new FileInputStream("/some dir /davebrown/Downloads/out.png"));
                    // Add image object into the Paragraphs collection of the section
                    section.getParagraphs().add(image);

pdf.save(pdfFile.getAbsolutePath());

Hello Dave,


Thanks for using our products.

I have tested the scenario while using Aspose.Pdf for Java 3.0.1 where I have tried converting the attached Penguin.PNG into PDF format and as per my observations, the image still has white background. Please take a look over the attached resultant PDF document.

Can you please share the source PNG image so that we can try converting it in our environment. We are really sorry for this inconvenience.

Sure! Attached is the input image and resultant pdf.



Note - this is Java.

Hi Dave,

Following is the code I used to generate the attached PDF file:

//Instantiate a Pdf object by calling its empty constructor`
Pdf pdf1 = new Pdf();

//Create a section in the Pdf object`
Section sec1 = pdf1.getSections().add();

//Create an image object in the section`
aspose.pdf.Image img1 = new aspose.pdf.Image(sec1);

//Add image object into the Paragraphs collection of the section`
sec1.getParagraphs().add(img1);

//Set the path of image file`
img1.getImageInfo().setFile("E:/AP Data/Feb2012/Archive/out.png");

//Set the title of image file`
img1.getImageInfo().setTitle("PDF image");

//Save the Pdf`
pdf1.save("E:/AP Data/Feb2012/Archive/PNG_image_toPDF.pdf");

I am using Java 1.6 version, Aspose.Pdf for Java 3.0.1 on a Windows 7 32 bit machine. Please share your complete code and environment details with us to help us reproduce the issue.

Hello Dave,

Adding more to Nausherwan's comments, I have also tried executing the same code snippet on Windows 7 Professional X64 machine running jdk1.6.0_20 and as per my observations, the source Image is properly being converted into PDF format. Please take a look over the attached resultant PDF document that I have generated. For your reference, I have also attached Aspose.Pdf for Java 3.0.1 which I am using in my environment.
