How extract truecolor image from an icon ?

I have in my code:

/* Iconification */
    struct DiskObject *iconify = NULL;

    // reset icon X/Y positions so it iconifies properly on Workbench
    if( (iconify=IIcon->GetIconTags("PROGDIR:DumbPad", ICONGETA_FailIfUnavailable,FALSE, TAG_END)) )
    {
     iconify->do_CurrentX = NO_ICON_POSITION;
     iconify->do_CurrentY = NO_ICON_POSITION;
    }


Which then i use as WINDOW_Icon, iconify. Now i want to use the same icon (in same ARGB format), to show up in the about window. Currently i do it like this:

// Create a Label object to wrap the icon image from DiskObject
                            Object *labelImage = NULL;
                            if (iconify && iconify->do_Gadget.GadgetRender)
                            {
                                labelImage = IIntuition->NewObject(NULL, "label.image",
                                    LABEL_Image, iconify->do_Gadget.GadgetRender,
                                    TAG_END);
                            }


And then just REQ_Image, labelImage. But then, it show me icon in 256 colors , which kind of expected because of do_Gadget.GadgetRender usage. Is there some easy and simple way to extract it from "iconify" so it will looks same true color one ? I mean something simple like some function with some tag or something ?

Thanks!

I use this code on one of my silly tools:
if(context)
 {
  struct Node *n;
  struct DiskObject *icon;
  struct ExamineData *dat;

  // Re-read theme drawer, but first "clean" listbrowser_list
  IListBrowser->FreeListBrowserList(listbrowser_list);

  while( (dat=IDOS->ExamineDir(context)) )
  {
   if( EXD_IS_FILE(dat) )
   {
    IUtility->Strlcpy(pointer_fullname, theme_drawer_name, DMP_MAX_SRC);
    IDOS->AddPart(pointer_fullname, dat->Name, DMP_MAX_SRC);
    pointer_fullname[IUtility->Strlen(pointer_fullname) - 5] = '\0'; // remove '.info'
//DBUG("'%s'\n",pointer_fullname);
    if( !(icon=IIcon->GetIconTags(pointer_fullname,
                              ICONGETA_FailIfUnavailable, TRUE, 
                              ICONGETA_UseFriendBitMap, TRUE,
                              //ICONGETA_Width,IMG_W,
                              //ICONGETA_Height,IMG_H, 
                              //ICONGETA_ForceScaling, TRUE,
                              //ICONGETA_AllowUpscaling, TRUE,
                             TAG_END)) ) break;

    if( (n=IListBrowser->AllocListBrowserNode(TOT_COL,//TOTALCOLUMNS,
                                              LBNA_Column,COL_IMG,
                                               LBNCA_Image,icon->do_Gadget.GadgetRender,
                                               //LBNCA_HorizJustify,LCJ_CENTER,
                                              LBNA_Column,COL_TXT,
                                               LBNCA_CopyText,TRUE, LBNCA_Text,dat->Name,
                                               //LBNCA_HorizJustify,LCJ_CENTER,
                                             TAG_DONE)) )
    {
     IExec->AddTail(listbrowser_list, n);
     ++success;
//DBUG("%2ld)MOUSEPOINTER='%s' [0x%08lx]\n",success,dat->Name,n);
    }
   }

  }


just change "listbrowser" stuff with your requester/gadget and see if icon shows full colors. Maybe just adding "ICONGETA_UseFriendBitMap, TRUE, " solves it.

ICONGETA_UseFriendBitMap, TRUE,

That one did the trick ! I simple create original icon with such a tag, and winOBJ take BOOPsi one with no probs as well. And for "about" there no needs for "label.gadget" usage, as boopsi image just can be placed into requester.
