HIOUtilityMagick

Detailed Description

class HIOUtilityMagick : public HInputHandler, public HOutputHandler

HIOUtilityMagick is the integration class for the ImageMagick toolkit. This integration is supported on all HOOPS platforms.

The windows distribution of HOOPS/3dF redistributes the ImageMagick development libraries for WIN32. These are located in Dev_Tools/3rdParty/ImageMagick.

For information on ImageMagick see: http://www.imagemagick.org/

Public Functions

~HIOUtilityMagick()
virtual char const *GetOutputName()
Returns:

A character pointer denoting the name of the handler.

virtual char const *GetInputName()
Returns:

A character pointer denoting the name of the input handler.

virtual void RegisterInputHandlerTypes()

This method registers the image types that are supported by ImageMagick for reading.

virtual HInputHandlerStyle GetInputStyle()
Returns:

The type of input style which is HInputHandlerStyleImage.

virtual char const *GetInputTypesString()
Returns:

The input extension types that are handled by HIOUtilityMagick which include “jpeg”, “gif”, “bmp” and “tif”.

virtual HFileIOResult FileInputToImageKey(__wchar_t const *filename, HC_KEY *image_key, HC_KEY segment_key, HInputHandlerOptions *options)

This method maps the data in the image file to a HOOPS image defined by image_key.

Parameters:

  • FileName – A character pointer denoting the name of the image file to read from.

  • image_key – The pointer to a HOOPS key that will be filled in with a HOOPS image key.

  • segment_key – The HOOPS segment key to create the image_key in i.e. the working segment.

  • options – The file input options.

Returns:

The #HFileOutputResult result of the operation.

virtual HFileIOResult FileInputToImageKey(unsigned short const *filename, HC_KEY *image_key, HC_KEY segment_key, HInputHandlerOptions *options)

This method loads image data from a given file to a given HOOPS image key. Note that this must be implemented in a sub-classed HInputHandler instance handling Images.

Parameters:

  • filename – The UNICODE name of the file to load.

  • image_key – The pointer to a HOOPS key that will be filled in with a HOOPS image key.

  • segment_key – The HOOPS segment key to create the image_key in — i.e., the working segment.

  • options – An options class containing any needed extra information for operation.

Returns:

The HFileInputResult result of the input operation.

virtual HFileIOResult FileInputToImageKey(char const *filename, HC_KEY *image_key, HC_KEY segment_key, HInputHandlerOptions *options)

This method loads image data from a given file to a given HOOPS image key. Note that this must be implemented in a sub-classed HInputHandler instance handling Images.

Parameters:

  • filename – The name of the file to load.

  • image_key – The pointer to a HOOPS key that will be filled in with a HOOPS image key.

  • segment_key – The HOOPS segment key to create the image_key in ie. the working segment.

  • options – An options class containing any needed extra information for operation.

Returns:

The HFileInputResult result of the input operation.

virtual void RegisterOutputHandlerTypes()

This method registers the image types supported by the Raster Pro toolkit for writing.

virtual HOutputHandlerStyle GetOutputStyle()
Returns:

The type of output style which is HOutputHandlerStyleImage.

virtual char const *GetOutputTypesString()
Returns:

The output extension types that are handled by HIOUtilityMagick which include “jpeg”, “gif”, “bmp” and “tif”.

virtual HFileIOResult FileOutputFromImageKey(__wchar_t const *filename, HC_KEY image_key, HOutputHandlerOptions *options)

This method exports the raster data contained in image_key to a file. It uses the file extension to determine what type of raster image to create.

Parameters:

  • filename – The name of the file to output.

  • image_key – The HOOPS image key to get output image data from.

  • options – The options class containing any needed extra information for the operation.

Returns:

The #HFileOutputResult result of the output operation.

HFileIOResult FileOutputFromImageKey(unsigned short const *filename, HC_KEY image_key, HOutputHandlerOptions *options)
virtual HFileIOResult FileOutputFromImageKey(char const *filename, HC_KEY image_key, HOutputHandlerOptions *options)

This method writes image data from a given HOOPS key to a given output file. Note that this must be implemented in a subclassed HOutputHandler instance handling images. This must be implemented in a subclassed HOutputHandler instance handling images.

Parameters:

  • filename – The name of the file to output.

  • image_key – The HOOPS image key to get output image data from.

  • options – The options class containing any needed extra information for the operation.

Returns:

The #HFileOutputResult result of the output operation.

HIOUtilityMagick()
