ExportJpeg Method

Description

Exports the current view to a JPEG file.

Syntax

Public Function ExportJpeg( _
   ByVal filename As String, _
   ByVal w As Long, _
   ByVal h As Long _
) As Integer

Parameters

filename

The name of the exported file.

 

w

The width of the bitmap, in pixels.

 

h

The height of the bitmap, in pixels.

Remarks

Note: To set image quality use setInt(SIS_OT_SYSTEM, 0, "_JpegQuality&",...) before using this API.

The ... is an integer in the range "0" to "100". It is recommended that a maximum value of "95" is used.

Using "100" will create a file two or three times as large as "95" but with hardly any improvement in quality. If you wish to create a very small file, perhaps for preview or indexing purposes and are prepared to tolerate large defects a value in the range "5" to "10" may be acceptable.

Size limits for the exported JPEG are 64k x 64k pixel size; 2GB file size.
