Merge JPG to PDF

Merge JPG to PDF

Aspose.Imaging allows to merge images from, JPG to PDF. Below example shows how to perform it for horizontal merge

using Aspose.Imaging;
using Aspose.Imaging.FileFormats.Jpeg;
using Aspose.Imaging.FileFormats.Tiff;
using Aspose.Imaging.FileFormats.Tiff.Enums;
using Aspose.Imaging.ImageOptions;
using Aspose.Imaging.Sources;
using Aspose.Imaging.Xmp;
using Aspose.Imaging.Xmp.Schemas.DublinCore;
using Aspose.Imaging.Xmp.Schemas.Photoshop;
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;

string templatesFolder = @"c:\Users\USER\Downloads\templates\";
string dataDir = templatesFolder;

string[] imagePaths = { dataDir + "template.jpg", dataDir + "template.jpeg" };

string outputPath = dataDir + "result.pdf";
string tempFilePath = dataDir + "temp.jpg";

// Getting resulting image size.
List<Size> imageSizes = new List<Size>();
foreach (string imagePath in imagePaths)
{
    using (RasterImage image = (RasterImage)Image.Load(imagePath))
    {
        imageSizes.Add(image.Size);
    }
}

int newWidth = imageSizes.Sum(size => size.Width);
int newHeight = imageSizes.Max(size => size.Height);

// Combining images into new one.
Source tempFileSource = new FileCreateSource(tempFilePath, isTemporal: true);
JpegOptions options = new JpegOptions() { Source = tempFileSource, Quality = 100 };
using (JpegImage newImage = (JpegImage)Image.Create(options, newWidth, newHeight))
{
    int stitchedWidth = 0;
    foreach (string imagePath in imagePaths)
    {
        using (RasterImage image = (RasterImage)Image.Load(imagePath))
        {
            Rectangle bounds = new Rectangle(stitchedWidth, 0, image.Width, image.Height);
            newImage.SaveArgb32Pixels(bounds, image.LoadArgb32Pixels(image.Bounds));
            stitchedWidth += image.Width;
        }
    }

    newImage.Save(outputPath, new PdfOptions());
}

File.Delete(outputPath);
File.Delete(tempFilePath);

and vertical merge

}

using (MemoryStream memoryStream = new MemoryStream())

    using (JpegImage newImage = (JpegImage)Image.Create(options, newWidth, newHeight))
    {

            {

                newImage.SaveArgb32Pixels(bounds, image.LoadArgb32Pixels(image.Bounds));
                stitchedHeight += image.Height;
            }
        }

        newImage.Save(outputPath, new PdfOptions());
    }
}

File.Delete(outputPath);
