Convert HTML to an image in C++

Modern C++ library allows C++ developers to convert HTML to an image with a few lines of code. HTML conversion engine analyses the original content, and exports the combined result as an image.

Use C++ to convert HTML to image format with maximum flexibility and speed. Run online live demo and check the highest output image quality right in a browser. HTML Conversion API supports a bunch of useful options.

Merge HTML into one image in C++

To convert HTML files to an image just use C++ library that handles all low-level details.

Convert multiple HTML and save the result as a single image. If you develop code in C++, HTML format conversion will be simpler than it sounds. See C++ example that iterates through source HTML files and combines them into an image:

Code example in C++ to combine multiple HTML to JPG

using namespace Aspose::Words;

std::vector<String> fileNames { u"Input1.html", u"Input2.html" };

auto output = MakeObject<Document>();
// Remove all content from the destination document before appending.
output->RemoveAllChildren();

for (const auto& fileName : fileNames)
{
    auto input = MakeObject<Document>(fileName);
    // Append the source document to the end of the destination document.
    output->AppendDocument(input, ImportFormatMode::KeepSourceFormatting);
}

for (int page = 0; page < output->get_PageCount(); page++)
{
    auto extractedPage = output->ExtractPages(page, 1);
    extractedPage->Save(String::Format(u"Output_{0}.jpg", page + 1));
}
