C++ library allows C++ developers to convert PNG images easily. PNG image conversion engine analyses the original PNG content, then exports the combined graphical content to the required format.
PNG image conversion may be tricky, unless you have a professional tool to do the job. Use C++ to convert PNG images with maximum flexibility and speed. Run online live demo and check the highest image quality right in a browser. PNG Conversion API supports a bunch of useful options.
Enhance PNG image format capabilities with Aspose.Words for C++. This is a simple way to combine PNG images with C++ library that handles all low-level details.
Merge PNG images and save the result as a single file. If you develop code in C++, this will be simpler than it sounds. See C++ example that iterates through PNG images and combines them:
using namespace Aspose::Words;
std::vector<String> fileNames { u"Input1.png", u"Input2.png" };
auto doc = MakeObject<Document>();
auto builder = MakeObject<DocumentBuilder>(doc);
std::vector<SharedPtr<Shape>> shapes;
for (const auto& fileName : fileNames)
{
auto shape = builder->InsertImage(fileName);
shapes.push_back(shape);
}
// Calculate the maximum width and height and update page settings
// to crop the document to fit the size of the pictures.
auto maxWidth = *std::max_element(shapes.begin(), shapes.end(),
[](auto lhs, auto rhs) return lhs->get_Width() < rhs->get_Width(); );
double maxHeight =
std::accumulate(shapes.begin(), shapes.end(), 1.0,
[](double result, auto shape) return result + shape->get_Height(); );
auto pageSetup = builder->get_PageSetup();
pageSetup->set_PageWidth(maxWidth->get_Width());
pageSetup->set_PageHeight(maxHeight);
pageSetup->set_TopMargin(0);
pageSetup->set_LeftMargin(0);
pageSetup->set_BottomMargin(0);
pageSetup->set_RightMargin(0);
doc->Save(u"Output.png");
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 PNG to many other file formats:
