Convert to external pictures

[Jim Knopf]

Hi,

my intention is to change the handling of pictures. Now they are included in documents but I will change to external pictures by disabling rvfoSavePicturesBody. So far so good.

But what can I do with documents that just contain pictures? What is the best way to stay compatible: new method - old projects? The problem is not so simple, because a Patchwork project may contain hundreds of single rvf files (each scene one file). Can I detect wether a file contains its pictures that I can expoert them? And, if, what is the best way to export them and set the new documents state?

Thank you in advance
Martin

Even if your document does not contain pictures, users can paste or drag&drop RTF containing internal pictures, and you need to handle them somehow. The best place to do it is before saving.
As for old documents, you can re-save them with excluded pictures options.

Before saving, you can enumerate all pictures in the document, find internal pictures and make them available externally.
See the demo in TRichView\Demos\DelphiUnicode\Assorted\Graphics\ShareImages\
The procedure for image processing before saving is TForm1.SaveAllUnknownImages.
