Unknown picture file extension (.gif)

I'm getting the exception "Unknown picture file extension (.gif)" when loading some Html content into TRichView using rvHtmlImporter.

How can I fix this?

What I meant is: Can I make TRichEdit / rvHtmlImporter ignore (don't try to load) gif's?

If you do not use TGifImage as it is explained in that topic, gif images will be ignored by default (loaded as RVStyle.InvalidPicture).

The exception is handled, it is noticeable only when debugging in IDE.

Sergey, I turns out that the Html code that contains the Gif reference should be removed before the rvHtmlImporter is used.

I load my Html into a Memo and manipulate the Html.

How do I get to use the rvHtmlImporter.LoadHtml from a Memo?

Version of Delphi?
Is HTML in UTF8?

Delphi Xe3
UTF8: Yes

Loading in memo:

Code: Select all

      Memo1.Lines.DefaultEncoding := TEncoding.UTF8;
      Memo1.Lines.LoadFromFile(OpenDialog1.FileName);

Importing:

Code: Select all

      RvHtmlImporter1.BasePath := ExtractFilePath(OpenDialog1.FileName);
      RvHtmlImporter1.Encoding := rvhtmleUTF8;
      RvHtmlImporter1.LoadHtml(UTF8Encode(Memo1.Lines.Text) );
