Bitmap Properties

The following methods return properties of the bitmap.

When these methods are called, they are passed to the BitmapStorage instance maintained by the Bitmap. The BitmapStorage implements these methods by returning the properties of the BitmapInfo instance maintained by the storage. Therefore, the values returned from the methods represent what is returned from the BitmapInfo instance associated with the Bitmap.

Detailed Description

Class for image input and output.

Description:
The Bitmap class is the bitmap itself. All image access is done through this class. The Bitmap class has methods to retrieve properties of the bitmap such as image width, height, whether it is dithered, has an alpha channel, etc. There are methods to retrieve and store pixels from the image. Additional methods allow a developer to copy bitmaps. This class also has methods to open outputs and write multi-frame files. All methods of this class are implemented by the system.
\par Examples 
The following is some examples of how to write some files out to disk:
To write a single image to a file/device, first create the Create BitmapInfo class: 
\code
BitmapInfo bi;
\endcode
Then define the output file or device:
\code
bi.SetName("file.tga");
\endcode
or use the BitmapManager:
\code
BitmapManager::SelectFileOutput( ... &bi ...)
\endcode
Then define your parameters for the Bitmap:
\code
bi.SetWidth(x)
bi.SetHeight(y)
etc...
\endcode
Then create the Bitmap:
\code
Bitmap* map = BitmapManager::Create(&bi);
\endcode
Then do something with the bitmap:
\code
map->Fill({0,0,0});
\endcode
Then you actually open, write and close the bitmap:
\code
map->OpenOutput(&bi);
map->Write(&bi);
map->Close(&bi);
map->DeleteThis();
\endcode

\par
To write a multi-frame file, just keep doing something different to
the Bitmap and keep writing. 
\par
To write a sequence of images to a file/device.
Create BitmapInfo class
\code
BitmapInfo bi;
\endcode
Define the output file/device, either directly
\code
bi.SetName(_T("E:\Renders\file.tga"));
\endcode
or using the user interface.
\code
BitmapManager::SelectFileOutput( ... &bi ...);
\endcode
The customize or define the BitmapInfo:
\code
bi.SetWidth(x)
bi.SetHeight(y)
bi.SetFirstFrame(0)
bi.SetLastFrame(29)
etc...
\endcode
Then create the Bitmap
\code
Bitmap* map = BitmapManager::Create(&bi);
\endcode
Then open the Bitmap for writing
\code
map->OpenOutput(&bi);
for (int x = 0; x < 29; x++)
{
    ## Do something to image...
    map->Write(&bi,x);
}
map->Close(&bi);
map->DeleteThis();
\endcode

\par
Note that in a localized environment there is no need to call BitmapInfo::SetDevice. This is because
calling Bitmap::OpenOutput will automatically determine the device type or BitmapIO type 
based off of the extension of the filename. 
Another alternative to manually setting the device type that even works in a localized environment is to
call BitmapInfo::FixDeviceName which will find the correct BitmapIO type based off of the extension.

\par
Note: You can add any number of outputs to a bitmap. Just keep
calling map->OpenInput() with different outputs (Targa file AND
Frame Buffer for instance). To write or close a specific output,
use Write()  and Close().  To write  and close them all at once,
use WriteAll() and CloseAll().

\par 
It is ok to use WriteAll() and CloseAll() if you have just one output defined.

BOOL  displayGamma = FALSE 
)
Remarks
Creates a new Windows Device Independent Bitmap (DIB) and returns a pointer to it. The DIB bitmap is created from this Bitmap. The DIB is allocated using LocalAlloc(). The pseudo-code below show how one may be created and freed. Note that the DIB is never used or accessed inside 3ds Max (the call to ToDib() is the first and last time that 3ds Max sees this pointer):

PBITMAPINFO pDib;
pDib = bitmap-\>ToDib();
...
BMMExport PBITMAPINFO ToDib(int depth=24, UWORD *gam=nullptr, BOOL doDither=FALSE, BOOL displayGamma=FALSE)
When you are done using the DIB call:

LocalFree(pDib);
Parameters:
int depth = 24

The bitmap depth; either 24 (BGR) or 32 (BGRO). If not specified the default is 24.

UWORD *gam=NULL

Specifies a pointer to an optional gamma table that is used to apply gamma correction to the color components as part of the conversion to a DIB. The table has RCOLN entries.

BOOL doDither=FALSE

Specifies if a random dither is applied when reducing the color components from 16 bits per channel to 8 bits per channel (to reduce banding effects).

BOOL displayGamma=FALSE

Specifies whether the output should be color corrected for screen display. If so, the gamma table parameter is ignored, and the DIB is color corrected using display gamma or LUT, as necessary.

◆ FromDib()

BMMExport BOOL FromDib ( PBITMAPINFO  pbmi)
Remarks
Converts the DIB to this bitmap's storage type. This bitmap's storage must already be allocated or the call will fail. The source must be 16, 24 or 32 bit. You cannot use an 8 bit DIB.
Parameters:
PBITMAPINFO pbmi

The source bitmap.
Returns
TRUE if the conversion was performed; otherwise FALSE.

◆ OpenOutput()

BMMExport BMMRES OpenOutput ( BitmapInfo bi)

Opens the image for output.

Remarks
This method will open the image for output. This allows the image to be written to. Note that you can pass a BitmapInfo to this method on which you simply set the file name 'by hand' (bi->SetName(_T("D:\renders\output.jpg"))). This will work and the correct driver (i.e. BitmapIO) will be selected based on the filename extension. This will work even in a localized environment, therefore there is no need to manually call BitmapInfo::SetDevice on the BitmapInfo that is passed to this function. However you won't be able to set any driver specific settings (such as compression settings for JPEGs). The alternative way is to use the BitmapManger methods.
Parameters
bi- Contains the name of the image or device to open for output.
Returns

BMMRES_SUCCESS - Indicates success.

BMMRES_ERRORTAKENCARE - Indicates that 3ds Max could not find a device to handle the image.

BMMRES_INTERNALERROR - Indicates the IO module handling the image could not be opened for writing.

◆ Write()

BMMExport BMMRES Write ( BitmapInfo bi,
int  frame = BMM_SINGLEFRAME 
)

Write the image from BitmapStorage to disk.

Remarks
Write the image from the BitmapStorage to disk. Note that you must pass the same BitmapInfo used when the file was first "Opened for Output". The main reason is that any device specific settings are kept in the BitmapInfo object. Also, the custom options such as gamma value, optional channels, etc (if any) are kept in this BitmapInfo instance. These are assigned when the bitmap is first opened (for either read or write).
Parameters
bi- Contains the name of the file or device to write to.
frame- Specifies the frame number to write. If this is a single image, allow frame to default to single frame. This argument determines if the file will have the frame number appended to it. If you want the file to have a normal name (no frame number attached to it), you must set the frame argument to BMM_SINGLEFRAME (the default). Any other value is considered to be a frame number and it will be appended to the given filename.
Returns
BMMRES_SUCCESS - Indicates success.

BMMRES_ERRORTAKENCARE - Indicates that 3ds Max could not find a device to handle the image.

BMMRES_INTERNALERROR - Indicates the IO module handling the image could not be opened for writing.

◆ WriteAll()

BMMExport BMMRES WriteAll ( int  frame = BMM_SINGLEFRAME)
Remarks
Write the image to all the open outputs.
Parameters:
DWORD frame = BMM_SINGLEFRAME

Returns
BMMRES_SUCCESS

Indicates success.

BMMRES_ERRORTAKENCARE

Indicates that 3ds Max could not find a device to handle the image.

BMMRES_INTERNALERROR

Indicates the IO module handling the image could not be opened for writing.

◆ Close()

MCHAR *title

The title to display.

◆ SetCroppingValues()

BMMExport void SetCroppingValues ( float  u,
float  v,
float  w,
float  h,
BOOL  placeImage 
)
Remarks
This method is used when the VFB is being displayed and you want to change the cropping rectangle from your plug-in. An example of this is available in /MAXSDK/SAMPLES/MATERIALS/BMTEX.CPP.
Parameters:
float u

The U value to set.

float v

The U value to set.

float w

The U value to set.

float h

The U value to set.

BOOL placeImage

TRUE for place mode; FALSE for crop.

◆ Fill() [1/3]

BMMExport int Fill ( int  r,
int  g,
int  b,
int  alpha 
)
Remarks
Sets every pixel of the bitmap to the specified color and alpha value.
Parameters:
int r

Specifies the red value to fill with.

int g

Specifies the green value to fill with.

int b

Specifies the blue value to fill with.

int alpha

Specifies the alpha value to fill with.
Returns
Nonzero if the operation succeeded; otherwise FALSE.

◆ Fill() [2/3]

BMMExport int Fill ( const BMM_Color_fl fillColor)
Remarks
Used by Maxscript.
Parameters:
fillColor

◆ Fill() [3/3]

BMMExport int Fill ( const BMM_Color_64 fillColor)
Remarks
Used by Maxscript.
Parameters:
fillColor

◆ SetNotify()

BMMExport void SetNotify ( BitmapNotify bmnot = nullptr)
Remarks
This method is used to set a callback to allow the developer to get notified if the storage for the Bitmap has changed.
Parameters:
BitmapNotify *bmnot=NULL

The pointer to the callback object implemented by the developer used to provide notification when the Bitmap's storage changes. See Class BitmapNotify.

◆ GetNotify()

BitmapNotify* GetNotify ( )
inline
Remarks
Returns a pointer to the callback used to notify a developer when the Bitmap's storage changes.
Default Implementation:
{ return bmNotify; };
4708 { return bmNotify; }

◆ IsAutonomousVFB()

BMMExport BOOL IsAutonomousVFB ( )
Remarks
Returns TRUE if the virtual frame buffer (VFB) is autonomous; otherwise FALSE. For instance, Video Post has an associated VFB. When Video Post is closed so is its VFB since it belongs to it. In that case the VFB is not autonomous. If the user does a View File command, that VFB is autonomous.

◆ Execute()

BMMExport INT_PTR Execute ( int  cmd,
ULONG_PTR  arg1 = 0,
ULONG_PTR  arg2 = 0,
ULONG_PTR  arg3 = 0 
)
Remarks
This is a general purpose function that allows the API to be extended in the future. The 3ds Max development team can assign new cmd numbers and continue to add functionality to this class without having to 'break' the API.
Parameters:
int cmd

The index of the command to execute.

ULONG arg1=0

Optional argument 1. See the documentation where the cmd option is discussed for more details on these parameters.

ULONG arg2=0

Optional argument 2.

ULONG arg3=0

Optional argument 3.
Returns
An integer return value. See the documentation where the cmd option is discussed for more details on the meaning of this value.

◆ GetModifyID()

DWORD GetModifyID ( )
inline
4742 { return modifyID; }

◆ SetModifyID()

void SetModifyID ( DWORD  m)
inline
4743 { modifyID = m; }

◆ IncrModifyID()

BMMExport void IncrModifyID ( )

◆ Print()

BMMExport void Print ( bool  silent = false)
Remarks
Sets every pixel of the bitmap to the specified color and alpha value.
Parameters:
int r

Specifies the red value to fill with.

int g

Specifies the green value to fill with.

int b

Specifies the blue value to fill with.

int alpha

Specifies the alpha value to fill with.
Returns
Nonzero if the operation succeeded; otherwise FALSE.

◆ ShowProgressLine()

BMMExport void ShowProgressLine ( int  y)
Remarks
This method is used for showing a moving scanline in a virtual frame buffer displaying this bitmap. Here's how it works. If you call ShowProgressLine(y), it clears any previously set white line, and sets an internal counter: you have to call Bitmap::RefreshWindow() to get the new white line to show up. From then that line will be displayed as white. To Clear it call ShowProgressLine(-1).
Parameters:
int y

The scanline to display as white (the count begins at zero). Use a value of -1 to hide the line.
