Implementation Guide

Rendering TGA to HTML

Overview: Convert a Truevision TGA file into an HTML format with embedded resources for easy web display.

Step 1: Define Output Directory

Create an output directory path where the rendered HTML files will be stored:

import java.nio.file.Path;

Path outputDirectory = TestFiles.getOutputDirectoryPath("YOUR_DOCUMENT_DIRECTORY", "RenderingTga");

Step 2: Set Up Rendering Options

Configure rendering options for HTML with embedded resources:

import com.groupdocs.viewer.Viewer;
import com.groupdocs.viewer.options.HtmlViewOptions;

Path pageFilePathFormat = outputDirectory.resolve("tga_result.html");

try (Viewer viewer = new Viewer(TestFiles.SAMPLE_TGA)) {
    HtmlViewOptions options = HtmlViewOptions.forEmbeddedResources(pageFilePathFormat);
    viewer.view(options);
}

Rendering TGA to JPG

Overview: Convert a Truevision TGA file into a JPEG image for better compatibility with various platforms.

Step 1: Define Output Directory and File Path

Path outputDirectory = TestFiles.getOutputDirectoryPath("YOUR_DOCUMENT_DIRECTORY", "RenderingTga");
Path pageFilePathFormat = outputDirectory.resolve("tga_result.jpg");

Step 2: Set Up Rendering Options

Configure rendering options for the JPG format:

import com.groupdocs.viewer.options.JpgViewOptions;

try (Viewer viewer = new Viewer(TestFiles.SAMPLE_TGA)) {
    JpgViewOptions options = new JpgViewOptions(pageFilePathFormat);
    viewer.view(options);
}

Rendering TGA to PNG

Overview: Convert a Truevision TGA file into a PNG image, ideal for high-quality graphics.

Step 1: Define Output Directory and File Path

Path outputDirectory = TestFiles.getOutputDirectoryPath("YOUR_DOCUMENT_DIRECTORY", "RenderingTga");
Path pageFilePathFormat = outputDirectory.resolve("tga_result.png");

Step 2: Set Up Rendering Options

Configure rendering options for the PNG format:

import com.groupdocs.viewer.options.PngViewOptions;

try (Viewer viewer = new Viewer(TestFiles.SAMPLE_TGA)) {
    PngViewOptions options = new PngViewOptions(pageFilePathFormat);
    viewer.view(options);
}

Rendering TGA to PDF

Overview: Convert a Truevision TGA file into a PDF document for easy distribution and archiving.

Step 1: Define Output Directory and File Path

Path outputDirectory = TestFiles.getOutputDirectoryPath("YOUR_DOCUMENT_DIRECTORY", "RenderingTga");
Path pageFilePathFormat = outputDirectory.resolve("tga_result.pdf");

Step 2: Set Up Rendering Options

Configure rendering options for the PDF format:

import com.groupdocs.viewer.options.PdfViewOptions;

try (Viewer viewer = new Viewer(TestFiles.SAMPLE_TGA)) {
    PdfViewOptions options = new PdfViewOptions(pageFilePathFormat);
    viewer.view(options);
}

Practical Applications
