Modern C++ library allows C++ developers to convert HTML to PNG image format with a few lines of code. HTML conversion engine analyses the original content, and exports the combined result as one PNG image.
Use C++ to convert HTML to PNG image format with maximum flexibility and speed. Run online live demo and check the highest output PNG image quality right in a browser. HTML Conversion API supports a bunch of useful options.
To convert HTML files to PNG image just use C++ library that handles all low-level details.
Convert multiple HTML and save the result as a single PNG 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 one PNG image:
dotnet add package Aspose.Words.Cpp
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}.png", page + 1));
}
There are three options to install Aspose.Words for C++ to your developer environment. Please choose one that resembles your needs and follow the step-by-step instructions:
You can use this C++ library to develop software on Microsoft Windows, Linux and macOS operating systems:
If you develop software for Linux or macOS, please check information on additional library dependencies (fontconfig and mesa-glu open-source packages) in Product Documentation.
You can merge HTML to many other file formats:
