L_INT EXT_FUNCTION L_InetSendSaveCmd(hComputer, uCommandID, pszFile, uBitmapID, nFormat, nBitsPerPixel, nQFactor, uFlags)

L_COMP hComputer;	/* handle to remote computer*/
L_UINT uCommandID;	/* message id*/
L_TCHAR L_FAR * pszFile;	/* file name*/
L_UINT uBitmapID;	/* bitmap id*/
L_INT nFormat;	/* file format*/
L_INT nBitsPerPixel;	/* resulting file's pixel depth*/
L_INT nQFactor;	/* quality factor*/
L_UINT uFlags;	/* flags that determines the save behavior*/

Sends a save command to a remote computer.

Parameter	Description
hComputer	Handle of the remote computer to which the command will be sent.
uCommandID	Command ID. Each command sent by a member of a connection should have a unique ID. Since a member of a connection may send several commands, this ID allows that member to identify when a specific command request has been completed.
pszFile	Character string containing the name of the image file to save.
uBitmapID	Id of the bitmap to save.
nFormat	Output file format. For valid values, refer to Formats of Output Files.
nBitsPerPixel	Resulting file's pixel depth. Note that not all bits per pixel are available to all file formats. For valid values, refer to Formats of Output Files. If nBitsPerPixel is 0, the file will be stored using the closet BitsPerPixel value supported by that format. For example, if a file format supports 1, 4, and 24 BitsPerPixel, and the BitsPerPixel is 5, the file will be stored as 24 bit. Likewise, if the BitsPerPixel is 2, the file will be stored as 4 bit.
nQFactor	This parameter is used when saving an image file to FILE_CMP, FILE_JFIF, FILE_LEAD1JFIF, FILE_LEAD2JFIF, FILE_JTIF, FILE_LEAD1JTIF, FILE_LEAD2JTIF, FILE_FPX_JPEG_QFACTOR, and FILE_EXIF_JPEG. Qfactor is a number that determines the degree of loss in the compression process.
	For possible values, refer to Compression Quality Factors.
uFlags	Binary flags that determine the behavior of save. You can specify one of the following values listed below, or set user-defined flags.
	Value	Meaning
	SAVEFILE_FIXEDPALETTE	[0x0001] The function uses the fixed palette for images that are saved as 8 bits per pixel or less.
	SAVEFILE_OPTIMIZEDPALETTE	[0x0002] The function uses the individual image's optimized palette for images that are saved as 8 bits per pixel or less. The optimized palette must be included in the bitmap handle.
	SAVEFILE_MULTIPAGE	[0x0004] The function saves the image in a multi-page file. It appends the image as the last one in the file. You can save multi-page images in PCX, GIF, and most TIFF file formats (including JTIF, but excluding EXIF).

Returns

SUCCESS	This function was successful.
< 1	An occurred. Refer to Return Codes.

Comments

The remote computer should respond by calling L_InetSendSaveRsp in its INETCOMMANDCALLBACK function. This callback function must be set using L_InetSetCommandCallback.

With this command, the local computer will signal the remote computer to save a bitmap.

To receive responses to commands, provide an INETRESPONSECALLBACK function. This function must be set using L_InetSetResponseCallback.

The INETCOMMANDCALLBACK function will receive the pszFile, uBitmapID, nFormat, nBitsPerPixel, nQFactor and uFlags information in the pParams parameter. The pszFile information will be in pParams[0]. The uBitmapID information will be in pParams[1], the nFormat information will be in pParams[2], and so forth.
