Getting images from an RTF file

[sarabjs]

Hi, I need to collect the images from an RTF file as image objects that I can work on individually. Any ideas? I tried loading the RTF file in the RTFTextBox in WinForms. The images show up correctly, but I still haven't figured out a way of accessing them directly. Hope someone can help. Thanks! Sarab

That won't be easy. You will need to read RTF specification. Here is an article that does the opposite you want: inserts images in richtextbox so it might help to understand basic concepts: Insert Plain Text and Images into RichTextBox at Runtime[^]

Hi Giorgi, Yes - that's the problem! I've found plenty of examples describing how to insert images into RTF but none on how to do the opposite! Am surprized no one else has had the need for this.. Hope someone else can help ... ? Sarab

The RTF specification is available here[^] if that's any help. I think you're gonna have to parse the rtf and reconstruct the image from the data that's embedded.

Hi, Thanks to everyone for your ideas! I managed to get the images. Here's how: Images in RTF are as hexadecimal strings (as noted from the specifications). So all that needed to be done was: 1. Convert the hexadecimal to a byte array: http://www.koders.com/csharp/fid8BD422682325288B294A97714AC061D115F0307D.aspx[^]) 2. Then make an image out of this array: byte[] bData; // The byte array MemoryStream memStream = new MemoryStream(bData, 0, bData.Length); Image iMage = Image.FromStream(memStream); Et voila! Sarab
