MHTML to JPG by a few lines of Java code

The static methods of the Converter class are primarily used as the easiest way to convert an MHTML file into various formats. You can convert MHTML to JPG in your Java application literally with a few lines of code!

1    // Open an existing MHTML file for reading
2    final  FileStream stream = File.openRead(StringExtensions.concat(getDataDir(),  "sample.mht"));
3    try {        }
4    finally { if (stream != null) ((IDisposable)stream).dispose(); }
5
6    // Invoke the convertMHTML() method to convert MHTML to JPG
7    com.aspose.html.converters.Converter.convertMHTML(stream, new ImageSaveOptions(ImageFormat.Jpeg), Path.combine(getOutputDir(), "convert-by-few-lines.jpg"));

Convert MHTML to JPG

The JPG format is known for its high-quality image data with lossless compression, which makes it a popular choice for sharing images on the web, computers, and mobile devices. Using Aspose.HTML, you can easily convert MHTML files to JPG format with full control over various conversion parameters.

Let’s walk through the step-by-step instructions for a simple MHTML to JPG conversion scenario:

Open an existing MHTML file. In the example, we use the openRead() method to open and read an MHTML file from the file system at the specified path.
Create an instance of ImageSaveOptions with JPG ImageFormat. By default, the ImageFormat is PNG.
Use the convertMHTML(stream, options, savePath) method of the Converter class to save MHTML as a JPG image file. The method takes as parameters stream, options, and savePath and performs the conversion.

Using convertMHTML() methods is the most common way to convert MHTML files into various formats. The following Java code snippet shows how to convert MHTML to JPG using Aspose.HTML:

 1    // Open an existing MHTML file for reading
 2    final  FileStream stream = File.openRead(StringExtensions.concat(getDataDir(),  "sample.mht"));
 3    try {        }
 4    finally { if (stream != null) ((IDisposable)stream).dispose(); }
 5                    
 6    // Create an instance of ImageSaveOptions
 7    ImageSaveOptions options = new ImageSaveOptions(ImageFormat.Jpeg);
 8
 9    // Prepare a path to save the converted file 
10    String savePath = Path.combine(getOutputDir(), "sample-output.jpg");
11
12    // Convert MHTML to JPG
13    com.aspose.html.converters.Converter.convertMHTML(stream, options, savePath);

Convert MHTML to JPG in Java using ImageSaveOptions

Aspose.HTML for Java allows converting MHTML to JPG using default or custom save options. Setting different options of ImageSaveOptions class gives you control over the page size, margins, background color, and resolution settings for the output image. These are the steps to convert an MHTML file to JPG format with ImageSaveOptions specifying:

Open an existing MHTML file. Use the openRead() method of System.IO.FileStream class to open and read source files from the file system at the specified path.
Create a new ImageSaveOptions object with JPG ImageFormat and specify the required save options:
- Use the getBackgroundColor() method to set the background color of the image to Beige.
- Use the setAnyPage() method to set the size of the image.
Use the convertMHTML(stream, options, savePath) method to save MHTML file as a JPG image. The method takes the stream, options, output file path savePath and performs the conversion operation.

The following Java example shows how to use ImageSaveOptions and create a JPG file with custom page-size, margins, resolution, rendering quality, and background color:

 1    // Open an existing MHTML file for reading
 2    final  FileStream stream = File.openRead(StringExtensions.concat(getDataDir(),  "sample.mht"));
 3    try {        }
 4    finally { if (stream != null) ((IDisposable)stream).dispose(); }
 5
 6    // Prepare a path to save the converted file 
 7    String savePath = Path.combine(getOutputDir(), "sample-options.jpg");
 8
 9    // Initailize the ImageSaveOptions with a custom page size and a background color 
10    ImageSaveOptions options = new ImageSaveOptions(ImageFormat.Jpeg)
11    {,
12        PageSetup =
13            {
14                AnyPage = new Page()
15                {
16                    Size = new com.aspose.html.drawing.Size(Length.FromPixels(1000), Length.FromPixels(500))
17                }
18            }
19        BackgroundColor = com.aspose.ms.System.Drawing.Color.getBeige()
20    };
21
22    // Call the convertMHTML() method to convert MHTML to JPG
23    com.aspose.html.converters.Converter.convertMHTML(stream, options, savePath);
