Add_Image_To_PDF.cpp

// Load the PDF file
auto pdfDocument = MakeObject<Document>(u"SourceDirectory\\PDF\\Sample 1.pdf");

// Retrieve the first page
auto page = pdfDocument->get_Pages()->idx_get(1);

// Create an instance of the Rectangle class
double x = 100.0, y = 600.0, width = 200.0, height = 200.0;
auto rectangle = MakeObject<Aspose::Pdf::Rectangle>(x, y, x + width, y + height);

// Add image to the page
page->AddImage(u"SourceDirectory\\Images\\AsposeLogo.png", rectangle);

// Save the PDF file
pdfDocument->Save(u"OutputDirectory\\add_image_output.pdf");

Delete_Image_From_PDF.cpp

// Load the PDF file
auto pdfDocument = MakeObject<Document>(u"OutputDirectory\\add_image_output.pdf");

// Delete a particular image
pdfDocument->get_Pages()->idx_get(1)->get_Resources()->get_Images()->Delete(1);

// Save the PDF file
pdfDocument->Save(u"OutputDirectory\\delete_image_output.pdf");

Extract_Image_From_PDF.cpp

// Load the PDF file
auto pdfDocument = MakeObject<Document>(u"OutputDirectory\\add_image_output.pdf");

// Extract a particular image
auto image = pdfDocument->get_Pages()->idx_get(1)->get_Resources()->get_Images()->idx_get(1);

// Create a stream object to save the output image
System::SharedPtr<System::IO::FileStream> outputImage = System::IO::File::Create(u"OutputDirectory\\extract_image_output.jpg");

// Save the output image
image->Save(outputImage, System::Drawing::Imaging::ImageFormat::get_Jpeg());

// Close the stream
outputImage->Close();

Replace_Image_In_PDF.cpp

// Load the PDF file
auto pdfDocument = MakeObject<Document>(u"OutputDirectory\\add_image_output.pdf");

// Open the new image with FileStream
System::SharedPtr<System::IO::FileStream> newImage = System::IO::File::OpenRead(u"SourceDirectory\\Images\\aspose.png");

// Replace the old image
pdfDocument->get_Pages()->idx_get(1)->get_Resources()->get_Images()->Replace(1, newImage);

// Close the stream
newImage->Close();

// Save the PDF file
pdfDocument->Save(u"OutputDirectory\\replace_image_output.pdf");
