I want to make a Host Image Processing application using Delphi which can handle Adobe Photoshop plugins.

Is it possible ?

I wonder if you could give me some example... maybe some codes...  ;)

That the API is old is no problem. Look at the old filters like KPT which continue to work with new Photoshops.

It's in the Photoshop directory. Not sure if it is the right one.

Ok, get ready 'coz here we go!

To get the Photoshop type library do the following in Delphi:
- Project Menu > Import Type Library
- Click 'Add' and browser to the Photoshop directory (usually C:\Program Files\Adobe\Photoshop 5.x) and select 'TypeLibrary.tlb'
- Now click on 'Create Unit'
- Save this unit to the project directoy where you want to use it
- In your project add these unit to the uses clause:

uses ComObj, ActiveX, PhotoShopTypeLibrary_TLB;


- To start Photoshop:

  PS: IPhotoShopApplication;
  AppWasRunning: boolean;
  Result: HRESULT;
  Unknown: IUnknown;

  AppWasRunning := False;
  Result := GetActiveObject(CLASS_PhotoshopApplication, nil, Unknown);
  if (Result = MK_E_UNAVAILABLE) then
    PS := CoPhotoshopApplication.Create
  else begin
    { make sure no other error occurred during GetActiveObject }
    OleCheck(Result);
    OleCheck(Unknown.QueryInterface(IPhotoShopApplication, PS));
    AppWasRunning := True;
  end;


- To make it visible:

  PS.Set_Visible(true);


- To stop Photoshop:

  PS.Quit;


- To load and save a picture:

  Pic: IAutoPSDoc;

  Pic := PS.Open('Picture.psd');
  Pic.SaveTo('Picture2.psd');


- To play an action:

  PS.PlayAction('Large Round Button');


- To apply a filter (plugin) to the active picture:

  AC: IActionControl;
  AD: IActionDescriptor;

  AC := PS.MakeControlObject;
  AD := PS.MakeDescriptor;
  AD.PutDouble(phKeyRadius, 10.3);
  AC.Play(phEventGaussianBlur, AD, phDialogSilent);

or

  AC := PS.MakeControlObject;
  AD := PS.MakeDescriptor;
  AD.PutInteger(phKeyAmount, 50);
  AC.Play(phEventSpherize, AD, phDialogSilent);



More info can be found in the SDK document 'Photoshop OLE Automation.pdf'.

Epsylon.

What error do you get? Or have you already solved it?

Maybe you use another Delphi version...
