Convert image to PDF in C++ using Aspose.PDF - Orientation error and exceptions

Aspose.PDF Product Family
1

Hi,

I’m testing Aspose.Pdf for C++ 2020.12

Found three problems:

  • Do not deal with orientation in exif. (Test file 1)
  • Do not support frames of images. (Test file 2)
  • Do not support old style tiff (Test file 2)
    • Error message:System::ArgumentException: __cdecl System::Drawing::Bitmap::Bitmap(const class System::SmartPtr<class System::IO::Stream> &,bool)

Here is my test code

void imageToPdf() {
    auto doc = System::MakeObject<Aspose::Pdf::Document>();
    auto page = doc->get_Pages()->Add();

    // 无法自动根据exif信息旋转图片
    System::String fileName = System::String(u"F:\\Users\\zhuying\\Desktop\\自带旋转的图片.jpg");

    auto fileStream = System::MakeObject<System::IO::FileStream>(fileName, System::IO::FileMode::Open, System::IO::FileAccess::Read);
    auto bmp = System::MakeObject<System::Drawing::Bitmap>(fileStream);
    auto r = System::MakeObject<Aspose::Pdf::Rectangle>(0.0, 0.0, (double)bmp->get_Width(), (double)bmp->get_Height());
    page->set_CropBox(r);

    // 设置页面大小
    auto pageInfo = page->get_PageInfo();
    pageInfo->get_Margin()->set_Bottom(0);
    pageInfo->get_Margin()->set_Top(0);
    pageInfo->get_Margin()->set_Left(0);
    pageInfo->get_Margin()->set_Right(0);
    page->SetPageSize(r->get_Width(), r->get_Height());

    page->AddImage(fileStream, r);
    fileStream->Close();
    doc->Save(u"imageToPdf.pdf");
}

  2. 自带旋转的图片.zip (2.8 MB)
