Hello...

Now is possible to import embedded images ?

[Sergey Tkachenko]

Both RvHtmlImporter and RvHtmlViewImporter components support it.

If you use Delphi XE7 or newer, it works automatically.
If you use Delphi XE6 or older:
- download and unpack DIMime http://www.yunqa.de/delphi/products/mime/index
- for RvHtmlImporter: remove dot from {.$DEFINE RVUSEDMIME} in rvhtmlimport.pas
- for RvHtmlViewImporter: remove dot from {.$DEFINE RVUSEDMIME} in rvHtmlViewImport.pas

Is that feature accessible now?

[Sergey Tkachenko]

Yes, it is.

[Sergey Tkachenko]

This example is obsolete.

Since TRichView v21, this is a built-in feature that does not require third-party units.
Just include rvhtmlsioInlineImages in RichView.HTMLSaveProperties.ImageOptions.
