Parameter

Description

lpszFile

Character string containing the name of the file to load.

nBitsTo

Resulting pixel depth of bitmaps in the list. Possible values are:

Value

Meaning

0

Keep the original file's pixel depth (Do not convert).

1 to 8

The specified bits per pixel in the resultant bitmaps

12

12 bits per pixel in the resultant bitmap.

16

16 bits per pixel in the resultant bitmaps

24

24 bits per pixel in the resultant bitmaps

32

32 bits per pixel in the resultant bitmaps

48

48 bits per pixel in the resultant bitmap

64

64 bits per pixel in the resultant bitmap

nColorOrder

Color order for 16-, 24-, 32-, 48-, and 64-bit bitmaps. If the resultant bitmaps are less than 16 bits per pixel, this will have no effect since palletized images have no order. Possible values are:

Value

Meaning

ORDER_RGB

[0] Red, green, and blue color order

ORDER_BGR

[1] Blue, green, and red color order

ORDER_GRAY

[2] 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are only supported in the Document/Medical toolkits only.

ORDER_RGBORGRAY

[3] Load the image as red, green, blue OR as a 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are supported in the Document/Medical toolkits only.

ORDER_BGRORGRAY

[4] Load the image as blue, green, red OR as a 12 or 16-bit grayscale image. 12 and 16-bit grayscale images are supported in the Document/Medical toolkits only.

pLoadOption

Pointer to optional extended load options. Pass NULL to use the default load options.

pFileInfo

Pointer to a FILEINFO structure. This structure may contain file information used in loading an image, or it may be updated with information about the file being loaded.

If nothing is known about the file, pass NULL for this parameter, or declare a variable of type FILEINFO and set the FILEINFO.Flags to 0, then pass the address of the FILEINFO structure in this parameter. In this case, if the address of a FILEINFO structure is passed, the FILEINFO structure will be updated with the results of LFile::GetInfo.

If only the file type is known, set pFileInfo.Format to the file type and set pFileInfo.Flags to FILEINFO_FORMATVALID. This can also be done if LFile::GetInfo has been called previously, but values that affect the size of the image loaded have been changed (for example, by calling LFileSettings::SetPCDResolution or LFileSettings::SetWMFResolution). In this case the FILEINFO structure pointed to by pFileInfo will be updated with the results of LFile::GetInfo.

If LFile::GetInfo has been called prior to calling this function, and no changes have been made to the contents of the structure filled by LFile::GetInfo, then the address of the filled FILEINFO structure can be passed for this parameter. In this case, the FILEINFO.Flags member should be set to FILEINFO_INFOVALID. The LFile::GetInfo function will set the FILEINFO.Flags to FILEINFO_INFOVALID. In this case the load will be faster since this function does not have to query the file filters for the file type.

SUCCESS_ABORT

The method was successful, but one or more pages could not be loaded. This bitmap list contains the pages which could were loaded properly.

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.
