For html pages you often include large pictures,
which are shown smaller in the document,
and when you click on it, you get the picture in full size.

It would be nice when you make a (large) picture smaller,
that the picture would change automatically to a hot picture
(linked to the orginal picture location).

Is this possible ?

thanks,

No, you need to do it yourself.

But usually HTML pages includes not a scaled large picture but a smaller version of picture.

ok, I'll do it myself,
is there some event, when a picture is resized with the mouse cursor ?

2.
Apperently I expressed myself wrong,
because that's exactly what I mean

thanks,[/quote]

Sorry, there is no such event.
If you want to convert scaled pictures automatically, I think it's better to do it for all pictures in the document just before HTML saving.

I used the onSaveItemToFile event,
and the implementation (shown below) is very straight forward.
It only adds hotspot information if image is resized.

cheers,


procedure Tform_rve_edit.RVESaveItemToFile(Sender: TCustomRichView;
const Path: String; RVData: TCustomRVData; ItemNo: Integer;
SaveFormat: TRVSaveFormat; Unicode: Boolean; var OutStr: String;
var DoDefault: Boolean);
(*******************************************************************************
*******************************************************************************)
var
filnam :string;
gr :tgraphic;
s :string;
tag :integer;
Valign :trvValign;
w,h :integer;
begin
if (RVData.GetItemStyle(ItemNo)=rvsPicture) or
(RVData.GetItemStyle(ItemNo)=rvsHOTpicture) then
begin
if SaveFormat=rvsfHTML then
begin
TCustomRichViewEdit(Sender).GetPictureInfo(ItemNo,filnam,gr,VAlign,Tag);
filnam:=ExtractRelativePath(This_Filename,filnam);
TCustomRichViewEdit(Sender).GetItemExtraIntProperty(ItemNo,rvePimagewidth,w);
TCustomRichViewEdit(Sender).GetItemExtraIntProperty(ItemNo,rvePimageheight,h);
if (gr.Width<>w) or (gr.Height<>h) then
begin
outstr:='<a href="'+filnam+'">'+
'<img width='+inttostr(w)+' height='+inttostr(h)+
' alt=""'+
' src="'+filnam+'"></a>';
dodefault:=false;
end;
end;
end;
end;

terrible layout

is there a way to improve that,
or isn't it even allowed to post code snippets ?

cheers,

Select the text and press Code button.
Text between [code] and [/code] is formated using monospaced font.

ok, new try

Correction:

everywhere where "TCustomRichViewEdit(Sender)" is used,
this should be replaced by "RVData",
otherwise it goes wrong if images are in tables.


cheers,

Correction2:

This shouldn't be done of course with a hotpicture
