[02/03] assistance requested - Extract image from RTF stream

[herrybeest]

Has anyone extracted or fetched a image/metafile from an RTF stream. Either parse the RTF stream, or using the RichTextBox Control? I know how to insert metafiles/images, extract text, including unicode.....

I've attempted to use rtb.control.count - this returns zero. The rtf file in question contains 28 images. These images need to be programmitcally extracted, not manually extracted.

I started working on this for you, and this is as far as I got:

Dim reg As New System.Text.RegularExpressions.Regex("\{\\(pict)\\(((.)|(\n))[^\}])*")
        Try
            For Each str As System.Text.RegularExpressions.Match In reg.Matches(Me.RichTextBox1.Rtf)
                Stop
            Next str
        Catch ex As Exception
            Stop
        Finally
 
        End Try

From here, I think it gets a little more involved (determining image types, placing them into streams, attempting to export them into indiv files). This will atleast give you the encoding informtation for the images.

Thank you for your assistance. Perhaps I should have stated the problem a little more clearly.

I do not have difficulty parsing the text from the rtf stream. ie: Searching for '\pict', finding rtf keywords, groups, etc..

The rtf doc contains 28 images, I can find \pict 28 times, sometimes the rtf control word \metafile is found.

Questions:
Do you know how the \pict data terminates?
The file in question was created with word2003. I understand word2003 writes a second set of image data for downward compatiblity with older rtf readers, do you kow how this data stream is tagged?
