Acrobat javascript codes

I need some codes for a few tasks in an Acrobat PDF file. There is one for Standar PDF file and some others for Acrobat 3D files. ---------------------------------------------------------------------------------------------------- For a standard Acrobat file. The goal is to send a pdf file to my client with a form that allows him to include his own logo and send the pdf file back to me. ----------------------------------------------------------------------------------------------------- For an Acrobat 3d scene. 1- Object opacity. I want an object called engine to have an opacity to 20%. 2- Scene background. Scene background should be transparent. 3- Show/hide layers, forms, and activate/desactivate 3dscene. A layer called 3d_01,and a group of forms that begin as but_01. should be hidden and showed with one click. Also the 3dscene should be activated and desactivated at the same time. The codes for point 3 should be saved in a JavaScript file (e.g. [login to view URL]) Fisrt line should be something like function action1 (show) 4- Embbeding the code and then call it by actions. I will embed the code created in point 3 ([login to view URL] ) in the 3dannotation. A form that call these functions and make them work should be created. Something like getAnnots3D(0)[0].[login to view URL] ("show");
