Convert HTML to TIFF

Converting a file to another format using the ConvertHTML() method is a sequence of operations among which document loading and saving:

1. Load an HTML file using the HTMLDocument class.
2. Create a new ImageSaveOptions object with TIFF ImageFormat. By default, the Format property is PNG.
3. Use the ConvertHTML() method of the Converter class to save HTML as a TIFF image. You need to pass the HTMLDocument, ImageSaveOptions, and output file path to the ConvertHTML() method to convert HTML to TIFF.

Please take a look over the following C# code snippet which shows the process of converting HTML to TIFF using Aspose.HTML for .NET.

// Prepare a path to a source HTML file
string documentPath = Path.Combine(DataDir, "nature.html");

// Prepare a path for converted file saving 
string savePath = Path.Combine(OutputDir, "nature-output.tiff");

// Initialize an HTML document from the file
using var document = new HTMLDocument(documentPath);

// Create an instance of the ImageSaveOptions class 
var options = new ImageSaveOptions(ImageFormat.Tiff);

// Convert HTML to TIFF
Converter.ConvertHTML(document, options, savePath);

Save Options

Aspose.HTML allows converting HTML to TIFF using default or custom save options. ImageSaveOptions usage enables you to customize the rendering process. You can specify the image format, page size, margins, compression level, CSS media-type, etc.

Property	Description
Compression	Sets Tagged Image File Format (TIFF) Compression. By default, this property is LZW.
CSS	Gets a CssOptions object which is used for configuration of CSS properties processing.
Format	Sets the ImageFormat (JPG, PNG, BMP, TIFF, or GIF). By default, this property is PNG.
BackgroundColor	This property sets the color that will fill the background. By default, this property is Transparent.
PageSetup	This property gets a page setup object and uses it for configuration output page-set.
HorizontalResolution	Sets horizontal resolution for output images in pixels per inch. The default value is 300 dpi.
VerticalResolution	Sets vertical resolution for output images in pixels per inch. The default value is 300 dpi.
UseAntialiasing	This property sets the image rendering quality. Antialiasing is enabled by default.
Text	Gets a TextOptions object which is used for configuration of text rendering.

Convert HTML to TIFF using ImageSaveOptions

To convert HTML to TIFF with ImageSaveOptions specifying, you should follow a few steps:

1. Load an HTML file using one of the HTMLDocument() constructors of the HTMLDocument class.
2. Create a new ImageSaveOptions object with TIFF ImageFormat and specify save options. By default, the Format property is PNG.
3. Use the ConvertHTML() method of the Converter class to save HTML as a TIFF image. You need to pass the HTMLDocument, ImageSaveOptions, and output file path to the ConvertHTML() method to convert HTML to TIFF.

The following C# code snippet shows how to convert HTML to TIFF using custom save options:

string documentPath = Path.Combine(DataDir, "nature.html");
string savePath = Path.Combine(OutputDir, "nature-output-options.tiff");


// Initialize an HTML Document from the html file
using var document = new HTMLDocument(documentPath);

// Initialize ImageSaveOptions 
var options = new ImageSaveOptions(ImageFormat.Tiff)
{
    Compression = Compression.None,
    BackgroundColor = System.Drawing.Color.Bisque,
    HorizontalResolution = 150,
    VerticalResolution = 150,
    UseAntialiasing = true,
};

// Convert HTML to TIFF
Converter.ConvertHTML(document, options, savePath);

The ImageSaveOptions() constructor initializes an instance of the ImageSaveOptions class that is passed to ConvertHTML() method. The ConvertHTML() method takes the document, options, output file path savePath and performs the conversion operation.

In the above example, we add:

• Compression property that sets TIFF compression. Available values are LVZ, CCITT3, CCITT4, Rle, and None. We use None compression schema. By default, this property is LZW.
• BackgroundColor property that sets the color that will fill the background. The default BackgroundColor is Transparent.
• HorizontalResolution and VerticalResolution properties that set horizontal/vertical resolution for output images in pixels per inch. By default, these properties are 300 dpi.
• UseAntialiasing property that sets the rendering quality for this image. Use UseAntialiasing = true when you want to improve the visual quality of rendered shapes, text, and images in your application, especially if clarity and smooth edges are essential.
