Detailed Description

Information about an image file or in-memory bitmap, including settings for loading/saving, gamma, etc.

See also: Class Bitmap, Working with Bitmaps, Bitmap Error (result) Codes

Description:: This class describes the properties of a bitmap such as its path name or device name, width, height, gamma, number of frames, etc. Methods are available to set and retrieve these properties. All methods are implemented by the system unless noted otherwise.

: In general, BitmapInfo should be used and saved for user-defined files rather than filenames, because the BitmapInfo encodes information beyond the filename, including file-format specific settings (e.g. compression on .JPG files) and so on.

: The file dialog functions (such as BitmapManager::SelectFileInput() or BitmapManager::SelectFileOutput()) can be seen as "BitmapInfo editors", since they allow the user to edit its content.

◆ Filename()

BMMExport const MCHAR* Filename ( )

Remarks: Returns just the file name of this BitmapInfo (not the entire path name).

◆ Device()

BMMExport const MCHAR* Device ( )

inline

Remarks: Returns the device name responsible for producing this image. For file types, this is just informative. For non-file types (devices) this is the way this image is identified. Therefore, it is important to save both name and device in order to properly identify an image.

1070 { return (const MCHAR *)device; }

MCHAR

#define MCHAR

MBCS/Unicode helper defines std::wofstream doesn't mix well with Unicode.

Definition: strbasic.h:42

◆ CompareName()

BMMExport BOOL CompareName ( BitmapInfo * bi )

Remarks: This method will compare names taking in consideration both file names and device names. As devices don't have a file name, this method will first determine what type of image this is, and then perform a proper comparison.

Parameters:: BitmapInfo *bi

The other BitmapInfo with which to compare names.

Returns: TRUE if the BitmapInfos have the same name and device name; otherwise FALSE.

◆ SetName()

BMMExport const MCHAR* SetName ( const MCHAR * n )

Set the path to the image file.

This is a convenience method and calls SetPath under the hood.

Parameters

n	New path for the bitmap.

Remarks: Sets the name property of this BitmapInfo. When writing n should have a fully qualified filename. When reading, it only matters if the image is not in the MAP path. Note that a "feature" of the MAP path system is that if an image with same name is found more than once (in different paths), only the first one is seen.

Note: If loading an image from a device, make sure the name is empty (bi.SetName(_M(""));). This is automatic if you use BitmapManager::SelectDeviceInput(). If you just create a BitmapInfo instance and set the device name by hand (bi.SetDevice()), this is also automatic as both name and device names are by default set to NULL (""). This is only a concern if you reuse a BitmapInfo class previously used for image files.

Parameters:: const MCHAR *n

Specifies the name of the bitmap.

Returns: The old (previous) name that was set.

◆ SetDevice()

BMMExport const MCHAR* SetDevice ( const MCHAR * d )

Sets the device name.

Remarks: This copies the supplied string into the member variable device. The string corresponds with the long description of a BitmapIO plugin: BitmapIO::LongDesc(). However it is not necessary to call this as the system will do it automatically when Bitmap::OpenOutput is called. Or as alternative, it can properly be set in a localized environment by calling BitmapInfo::FixDeviceName().

Parameters

d	- The name to set.

Returns: The device name that was set.

◆ GetPathEx()

BMMExport MaxSDK::Util::Path GetPathEx ( ) const

Returns the currently set path of the image file.

Returns: The currently set path of the image file.

◆ CopyImageInfo()

BMMExport void CopyImageInfo ( BitmapInfo * from )

Remarks: Copies the image information of the from BitmapInfo to this bitmap. Only the name, device and image characteristics are copied. User info, such as Custom Width, etc. is not copied.

The following properties of the from BitmapInfo are copied:

from->Name(),from->Device(),from->Width(), from->Height(), from->Aspect(), from->Gamma(),from->Type(), from->Flags(), from->FirstFrame(), from->LastFrame(), from->CurrentFrame(), from->GetCustomFlags()

Parameters:: BitmapInfo *from

The bitmap whose information will be copied.

◆ SetPath()

Parameters:: DWORD f

The flag bits to test.

Returns: Returns TRUE if the specified flags were set; otherwise FALSE.

1274 { return (customflags & f); }

◆ GetPiData()

BMMExport void* GetPiData ( )

inline

Returns the plugin data stored on the BitmapInfo.

The plugin data is set by BitmapIO class responsible for producing this image. The BitmapIO class stores its image specific data in the plugin data. For example, the avi BitmapIO class stores the compressor name, quality, and keyframe in the plugin data. The BitmapInfo owns the memory associated with the plugin data and will free the memory when deleted.

Returns: Pointer to the plugin data.

1286 { return pidata; }

◆ SetPiData()

BMMExport void SetPiData ( void * ptr )

inline

Sets the plugin data stored on the BitmapInfo.

This method is not normally called, rather a BitmapIO instance will call AllocPiData(), which will allocate the plugin data memory and set the plugin data size. The BitmapIO will then acquire the pointer to the plugin data memory via GetPiData()

Parameters

[in] ptr Pointer to the plugin data.

1293 { pidata = ptr; }

◆ GetPiDataSize()

BMMExport DWORD GetPiDataSize ( )

inline

Returns the size of the plugin data stored on the BitmapInfo.

Returns: Size of the plugin data.

1298 { return pisize; }

◆ SetPiDataSize()

BMMExport void SetPiDataSize ( DWORD s )

inline

Sets the reported size of the plugin data stored on the BitmapInfo.

This method is not normally called, rather a BitmapIO instance will call AllocPiData(), which will allocate the plugin data memory and set the plugin data size. The BitmapIO will then acquire the pointer to the plugin data memory via GetPiData()

Parameters

[in] s Reported size of the plugin data.

1305 { pisize = s; }

◆ ResetPiData()

BMMExport void ResetPiData ( )

Resets the plugin data stored on the BitmapInfo.

Frees existing plugin data memory and sets plugin data size to zero.

◆ AllocPiData()

BMMExport BOOL AllocPiData ( DWORD size )

Allocates the plugin data memory and set the plugin data size.

Acquire the pointer to the plugin data memory via GetPiData()

Parameters

[in] size Requested size of the plugin data.

◆ CreateFmtSpecBlock()

BMMExport void* CreateFmtSpecBlock ( void )

Remarks: This method is available in release 2.0 and later only.

This method provides some access to device specific data (for instance the compression ratio in a JPEG file). This method will return a buffer containing a given device specific data (or NULL if the device referenced is unknown or doesn't have "specific data"). The buffer structure will depend on the device. For all drivers shipped with the SDK, this structure is defined in their header files (which must be included in the project for which this method is used). Internally, this method validates the driver, calls its EvaluateConfigure() method to define the buffer size, creates this buffer and, if the returned size is greater than zero, calls the driver's SaveConfigure() method in order to set default values. The developer may then change whatever they want, create and write a file using this BitmapInfo which includes the device's specific data.

There is no need to free this buffer as this is handled by the BitmapInfo destructor.

Note: The name and/or device properties must be defined before using this method.

◆ Copy() [1/2]

BMMExport void Copy	(	const BitmapInfo *	from,
		BOOL	copyProxySubject
	)

Assignment function. The data members of the specified BitmapInfo are copied to this BitmapInfo, with option to also copy the proxySubject info.

◆ Copy() [2/2]

BMMExport void Copy ( const BitmapInfo * from )

◆ operator=()

BMMExport BitmapInfo& operator= ( const BitmapInfo & from )

Remarks: Assignment operator. The data members of the specified BitmapInfo are copied to this BitmapInfo.

Parameters:: BitmapInfo &from

The source BitmapInfo.

◆ Save()

BMMExport IOResult Save ( ISave * isave )

◆ Load()

BMMExport IOResult Load ( ILoad * iload )

◆ EnumAuxFiles()

BMMExport void EnumAuxFiles	(	AssetEnumCallback &	assetEnum,
		DWORD	vflags
	)

◆ Validate()

BMMExport BOOL Validate ( )

Remarks: Implemented by the System.

This method is used to check the width, height, aspect ratio, and gamma settings to make sure they are within an acceptable range of values. The comparison is as follows:

if (width < 1 ||

height < 1 ||

aspect <= 0.0 ||

gamma < MINGAMMA ||

gamma > MAXGAMMA)

return (FALSE);

else

return (TRUE);

Where:

#define MINGAMMA 0.2f

#define MAXGAMMA 5.0f

Returns: TRUE if the BitmapInfo's settings are valid ; otherwise FALSE.

◆ GetUpdateWindow()

BMMExport HWND GetUpdateWindow ( )

inline

Remarks: Returns the window handle to send progress or check abort messages to.

1398 { return hWnd; }

◆ SetUpdateWindow()

BMMExport void SetUpdateWindow ( HWND hwnd )

inline

Remarks: This is used internally - the system calls this method. This is how a window handle is sent down to device drivers and filters so they can send progress reports and check for cancel.

1402 { hWnd = hwnd; }

◆ GetGChannels()

BMMExport DWORD GetGChannels ( )

◆ GetDeviceFlags()

BMMExport DWORD GetDeviceFlags ( )

◆ FixDeviceName()

BMMExport BOOL FixDeviceName ( )

Sets the appropriate device name, as derived from the filename.
