I use LoadFromFileOnDemand and I need to perform certain actions when loading each page.
What event should I use? |

In the next release you can use the OnImageLoaded event. Also, the OnAllDisplayed event occurs after loading completes for all images.

Hi
I'll see if we can add a relevant event for the next update.

I need an event that occurs once at frame (page) loading.
This event occurs continuously during redrawing. |

I wish you had said that to begin with. I thought you wanted to process the bitmap. To add text to the frames use the GetText event.
procedure TForm1.ImageEnMView1GetText(Sender: TObject; Index: Integer;
Position: TIEMTextPos; var Text: WideString);
var
iBitDepth: Integer;
iColor: string;
begin
{ Set the bottom text }
ImageEnMView1.ImageBottomText[Index] := 'Frame ' + IntToStr(Index + 1);
iBitDepth := ImageEnMView1.MIO.Params[Index].BitsPerSample *
ImageEnMView1.MIO.Params[Index].SamplesPerPixel;
if iBitDepth = 24 then
iColor := 'RGBA 32-Bit'
else
iColor := 'RGB ' + IntToStr(iBitDepth) + '-Bit';
{ Set the info text }
ImageEnMView1.ImageInfoText[Index] := iColor;
ImageEnMView1.UpdateImage(Index);
ImageEnMView1.Update;
end;

At loading images in the ImageEmMView I need to read some parameters (Params) and add them to "ImageInfoText" |

It should work if you do not use LoadFromFileOnDemand. Try otherways to load the frames and put a break point in the event with a showmessage('I am in the xxx event') Not all of the events have a bitmap that you can process.

It is a pity. I want this event to work with multi-page files. |

I could be wrong of course, but I do not think there is an event that will execute that will allow processing a thumbnail frame bitmap when using LoadFromFileOnDemand. LoadFileOnDemand is mainly used for loading the frames of files with large number of frames (such as videos).

I don't use
TImageEnMView.FillFromDirectory
I use
ImageEnMView2->LoadFromFileOnDemand(TempFileTiff, false); |

What do you mean it does not work? OnImageAdd occurs whenever an image is added or when using TImageEnMView.FillFromDirectory as noted in the help file.

It doesn't work with my multipage file and this code
ImageEnMView2->LoadFromFileOnDemand(TempFileTiff, false); |

I believe you are looking for OnImageAdd.
