TIFF to PNG C++ Conversion Source Code

// Load the TIFF
SharedPtr<Presentation> pres = MakeObject<Presentation>(u"sourceFile.tiff");

// Access the first slide
SharedPtr<ISlide> slide = pres->get_Slides()->idx_get(0);

// User defined dimension
int desiredX = 1200;
int desiredY = 800;

// Getting scaled value  of X and Y
float ScaleX = (float)(1.0 / pres->get_SlideSize()->get_Size().get_Width()) * desiredX;
float ScaleY = (float)(1.0 / pres->get_SlideSize()->get_Size().get_Height()) * desiredY;

// Create a custom scale image
auto bitmap = slide->GetThumbnail(ScaleX, ScaleY);

bitmap->Save(u"output.png", ImageFormat::get_Png());
