Member Function Documentation

◆ ClosePage()

virtual void Aspose::Page::IMultiPageDevice::ClosePage ( )
pure virtual

◆ get_CurrentPageNumber()

◆ InitPageNumbers()

◆ OpenPage() [1/2]

virtual bool Aspose::Page::IMultiPageDevice::OpenPage ( System::String  title)
pure virtual

Makes necessary preparation of the device before page rendering.

Parameters
titleThe page title.
Returns
True if page is from requested range, otherwise false. Used in devices that can render specified array of page numbers.

Implemented in Aspose::Page::EPS::Device::ImageDevice, Aspose::Page::EPS::Device::PdfDevice, Aspose::Page::XPS::Presentation::Pdf::PdfDevice, Aspose::Page::XPS::Presentation::Image::ImageDevice, Aspose::Page::EPS::Device::ApsDevice, and Aspose::Page::XPS::Presentation::Ps::PsDevice.

◆ OpenPage() [2/2]

virtual bool Aspose::Page::IMultiPageDevice::OpenPage ( float  width,
float  height 
)
pure virtual

Makes necessary preparation of the device before each page rendering.

Parameters
widthA width of the page.
heightA height of the page.
Returns
Returns true if opened page has a number that falls in a range of selected page numbers and false otherwise.

Implemented in Aspose::Page::EPS::Device::ImageDevice, Aspose::Page::EPS::Device::PdfDevice, Aspose::Page::XPS::Presentation::Pdf::PdfDevice, Aspose::Page::XPS::Presentation::Image::ImageDevice, Aspose::Page::XPS::Presentation::Ps::PsDevice, and Aspose::Page::EPS::Device::ApsDevice.
