OEImageFileCreatorBase¶

class OEImageFileCreatorBase

The OEImageFileCreatorBase is an abstract class that is used to register concrete image types.

Constructors¶

OEImageFileCreatorBase(const std::string &ext, bool multi=false)

Default constructor.

ext: The file extension that will be used to identify the concrete image type. For example, the Portable Document Format (PDF) is registered with the “pdf” file extension.
multi: Determines whether the specific image type can be used to create multi-page images.

CreateCopy¶

OEImageFileCreatorBase *CreateCopy() const =0

Virtual const constructor which allows copying of concrete derived objects using a reference to this base class.

CreateImage¶

OEImageFileBase *CreateImage(double width, double height) const =0

The OEImageFileCreatorBase::CreateImage is a virtual method that has to be implemented in the concrete derived classes and it returns a pointer of concrete image with the given dimensions.

width: The width of the returned image.
height: The height of the returned image.

GetExtension¶

const std::string GetExtension() const

Return the file extension of which the concrete image type is being registered.

IsMultiPage¶

bool IsMultiPage() const

Returns whether the image type registered as multi-page image.
