Detailed Description

Base image module providing load/save support for images.

Constructor & Destructor Documentation

◆ deBaseImageModule()

deBaseImageModule::deBaseImageModule ( deLoadableModule loadableModule)

Create module.

◆ ~deBaseImageModule()

virtual deBaseImageModule::~deBaseImageModule ( )
virtual

Clean up module.

Member Function Documentation

◆ InitLoadImage()

virtual deBaseImageInfo* deBaseImageModule::InitLoadImage ( decBaseFileReader reader)
pure virtual

Quick check if the file can be loaded by this module.

This is usually a header check and is used to detect with what image module a file could be possibly loaded if it does not match any patterns. If the image can be loaded store the necessary informations into an ImageInfo object and return it. Otherwise return NULL. The returned ImageInfo object is used to create the image and as parameter to LoadImage. You can be sure that the file pointer is located at the beginning of the file.

◆ LoadImage()

virtual void deBaseImageModule::LoadImage ( decBaseFileReader reader,
deImage image,
deBaseImageInfo infos 
)
pure virtual

Load image.

You can be sure that the file pointer is at the same place left off after the prior call of CheckLoadImage on the same file and module. You can be sure that the image object specified in the function call has been created with the information stored in the infos parameter obtained from a prior call to the CheckLoadImage function.

◆ SaveImage()

virtual void deBaseImageModule::SaveImage ( decBaseFileWriter writer,
const deImage image 
)
pure virtual

Save image.

You can be sure that the file provided has been rewinded prior to this function call.
