Hello team,
The file that Aspose.Pdf generates is more than twice as big as the file that Aspose.Pdf.Generator generates.
This is my code.
private MemoryStream ConvertSingleImageToPdf()
{
var pdfStream = new MemoryStream();
// Instantiate the License class
var license = new Aspose.Pdf.License();
license.SetLicense("Aspose.Total.lic");
var pdf = new Aspose.Pdf.Document();
using (var image = Image.FromStream(this._stream))
{
// PDFファイルにページを追加
var pdfPage = pdf.Pages.Add();
// ページの余白を0に、ページサイズを画像の大きさに設定
pdfPage.PageInfo.Margin.Top = 0;
pdfPage.PageInfo.Margin.Bottom = 0;
pdfPage.PageInfo.Margin.Left = 0;
pdfPage.PageInfo.Margin.Right = 0;
pdfPage.PageInfo.Width = image.Width;
pdfPage.PageInfo.Height = image.Height;
// PDFイメージオブジェクトを作成
var pdfImage = new Aspose.Pdf.Image()
{
FixWidth = image.Width,
FixHeight = image.Height,
ImageStream = this._stream,
};
pdfPage.Paragraphs.Add(pdfImage);
// PDF保存
pdf.Save(pdfStream);
}
return pdfStream;
}
Thank you,

@PFU.DSOL2,
Kindly send us your source image file and let us know the difference between the output PDF file sizes. We will investigate your scenario in our environment and share our findings with you. Your response is awaited.

Hello team,
I have attached the image files and the pdf files.
Aspose.pdf.zip (1.1 MB)
I think this incident is similar.
Aspose.Pdf generates larger files than Aspose.Pdf.Generator
Thank you,

@PFU.DSOL2,
We have generated a new PDF and inserted all your input images with the latest version 17.8 of Aspose.Pdf for .NET API. The output PDF file has the least file size than your output PDF documents. This is the output PDF: Aspose.pdf.17.8.pdf (307.4 KB)
Source code C#
// Instantiate Document Object
Document doc = new Document();
for (int i = 1; i <= 5; i++)
{
// Add a page to pages collection of document
Aspose.Pdf.Page page = doc.Pages.Add();
// Set margins so image will fit, etc.
page.PageInfo.Margin.Bottom = 0;
page.PageInfo.Margin.Top = 0;
page.PageInfo.Margin.Left = 0;
page.PageInfo.Margin.Right = 0;
// Load the source image file to Stream object
FileStream fs = new FileStream(@"C:\Pdf\test198\page_" + i + ".jpg", FileMode.Open, FileAccess.Read);
byte[] tmpBytes = new byte[fs.Length];
fs.Read(tmpBytes, 0, int.Parse(fs.Length.ToString()));
MemoryStream mystream = new MemoryStream(tmpBytes);
// Instantiate BitMap object with loaded image stream
Bitmap b = new Bitmap(mystream);
page.CropBox = new Aspose.Pdf.Rectangle(0, 0, b.Width, b.Height);
// Create an image object
Aspose.Pdf.Image image1 = new Aspose.Pdf.Image();
// Add the image into paragraphs collection of the section
page.Paragraphs.Add(image1);
// Set the image file stream
image1.ImageStream = mystream;
}
// Save resultant PDF file
doc.Save(@"C:\Pdf\test198\Aspose.pdf.17.8.pdf");
Hello team,
I have checked in Aspose 17.8 and it seems OK.
Thank you,
