HTML-Export and Imagefilenames

[Ralf]

Hi all,

if i use RichViewEdit1.SaveHTMLEx to create an HTML-File, all Images will be renamed to "img[n].gif".

What can i do to leave the original Filenames of the Images inside the created HTML-File (with or without Path-Information)?

Is there an easy way to do this?

Thanks and Regards from Germany
Ralf

I guess you need to handle OnSaveImage2 event.

Where in my Code i have to do this?

Yes, you can save images in different files using OnSaveImage2 or OnHTMLSaveImage.
See also the help on "TRVExtraItemStrProperty type":

rvespImageFileName
Applicable to: pictures, hot-pictures, tables
Provides a place to store image file name (background image for table). For tables, this value is also accessible as table.
BackgroundImageFileName.
See also: TRVTableCellData.BackgroundImageFileName
If rvsoUseItemImageFileNames is included in the Options parameter of SaveHTML/SaveHTMLEx, images with defined (non-empty) file names will not be saved, but their file names will be written in HTML.

Thanks for helping, but i dont understand anything.

In Demo-Application "Editor 1" i have added:
SetHTMLOption(cbHTMLUseItemImageFileNames.Checked, rvsoUseItemImageFileNames); an a checkbox similar to the option.

But inside the generated HTML-File Images still named img1, img2 ...

I dont need to save the Imagesfile. I only need, that the Filename and Path from the Image is stored in HTML-Code.

Please can you help me again ...!?

Thanks and Regards
Ralf

It's because value of this property (rvespImageFileName) is empty for all images in this demo, and this demo does not allow to change this property.

[Ralf]

Great!

But HOW and WHERE have i to implement the property rvespImageFileName ????

How many things i have to do to effect a simple an normal thing!??!?

Is there any sample for this?

I'm wondering why it is so difficult to have Imagenames inside the HTML-Code. Normally this is a "must have" ...

Actually, it's simple.

Reading for the item (picture) at the position of caret:
rve.GetCurrentItemExtraStrProperty(rvespImageFileName, FileName).

Changing for the item (picture) at the position of caret
rve.SetCurrentItemExtraStrProperty(rvespImageFileName, FileName, True).

In the insert picture code, the following fragment should be changed

Code: Select all

      if gr<>nil then
        RichViewEdit1.InsertPicture('',gr,rvvaBaseLine);

to

Code: Select all

      if gr<>nil then begin
        RichViewEdit1.TopLevelEditor.BeginUndoGroup(rvutInsert); 
        RichViewEdit1.TopLevelEditor.SetUndoGroupMode(True); 
        try 
          if RichViewEdit1.InsertPicture('', gr, rvvaBaseline) then 
            RichViewEdit1.SetCurrentItemExtraStrProperty(
              rvespImageFileName, OpenDialog1.FileName, True); 
        finally 
          RichViewEdit1.TopLevelEditor.SetUndoGroupMode(False); 
        end; 
      end;
