Parameter

Description

pLBitmap

The pointer to the LBitmapBase object that references the thumbnail generated by LFile::BrowseDir. You can copy this bitmap, save it to file, insert it into a LEADTOOLS ImageList Control, or otherwise process it as needed in your application.

pszFilename

Character string containing the filename from which this thumbnail was generated.

pFileInfo

Pointer to a FILEINFO structure containing information about pszFilename.

nStatus

Status code. If an error occurred during thumbnail generation, this will be < SUCCESS. Possible values are:

Value

Meaning

BROWSE_LOADING

[2] Indicates image is being loaded, see nPercent.

BROWSE_SKIPPED

[3] Indicates image was skipped because it was larger than the specified range in LFile::BrowseDir.

BROWSE_PRELOAD

[4] Indicates that LEADTOOLS has found a file and is about to determine the file format. It will then attempt to create a thumbnail for it. If the user wishes to avoid the internal file information processing, return ERROR_FILE_FORMAT. This will cause LEADTOOLS to skip the file.

nPercent

Represents the percentage completion of a file load when nErrorCode is equal to BROWSE_LOADING.

> 0

The function was successful, and returns the handle to the ImageList Control window.

< 0
