with a thin black border. Initially this is convenient for precise positioning, but we disabled the border with linewidth=0. normalfont = p.load_font("Helvetica", "unicode", ""); p.begin_page_ext(pagewidth, pageheight, "topdown"); /* place the text line "Kraxi Systems, Inc." using a matchbox */ String optlist = "font=" + normalfont + " fontsize=8 position={left top} " + "matchbox={name=kraxi} fillcolor={rgb 0 0 1} underline"; p.fit_textline("Kraxi Systems, Inc.", 2, 20, optlist); /* create URI action */ optlist = "url={http://www.kraxi.com}"; int act = p.create_action("URI", optlist); /* create Link annotation on matchbox "kraxi" */ optlist = "action={activate " + act + "} linewidth=0 usematchbox={kraxi}"; /* 0 rectangle coordinates will be replaced with matchbox coordinates */ p.create_annotation(0, 0, 0, 0, "Link", optlist); p.end_page_ext(""); For an example of creating a Web link on an image or on parts of a textflow, see Section 8.4, »Matchboxes«, page 243. Cookbook A full code sample can be found in the Cookbook topic interactive/link_annotations. Bookmark for jumping to another file. Now let’s create the bookmark »Our Paper Planes Catalog« which jumps to another PDF file called paper_planes_catalog.pdf. First we create an action of Type GoToR. In the option list for this action we define the name of the target document with the filename option; the destination option specifies a certain part of the page which will be enlarged. More precisely, the document will be displayed on the second page (page 2) with a fixed view (type fixed), where the middle of the page is visible (left 50 top 200) and the zoom factor is 200% (zoom 2): String optlist = "filename=paper_planes_catalog.pdf " + "destination={page 2 type fixed left 50 top 200 zoom 2}"; goto_action = p.create_action("GoToR", optlist); In the next step we create the actual bookmark. The action option for the bookmark contains the activate event which will trigger the action, plus the goto_action handle created above for the desired action. The option fontstyle bold specifies bold text, and textcolor {rgb 0 0 1} makes the bookmark blue. The bookmark text »Our Paper Planes Catalog« is provided as a function parameter: String optlist = "action={activate " + goto_action + "} fontstyle=bold textcolor={rgb 0 0 1}"; catalog_bookmark = p.create_bookmark("Our Paper Planes Catalog", optlist); Clicking the bookmark will display the specified part of the page in the target document. 88 Chapter 3: Creating PDF Documents (Edition for <strong>COM</strong>, .<strong>NET</strong>, and REALbasic)
Cookbook A full code sample can be found in the Cookbook topic interactive/nested_bookmarks. Annotation with file attachment. In the next example we create a file attachment. We start by creating an annotation of type FileAttachment. The filename option specifies the name of the attachment, the option mimetype image/gif specifies its type (MIME is a common convention for classifying file contents). The annotation will be displayed as a pushpin (iconname pushpin) in red (annotcolor {rgb 1 0 0}) and has a tooltip (contents {Get the Kraxi Paper Plane!}). It will not be printed (display noprint): String optlist = "filename=kraxi_logo.gif mimetype=image/gif iconname=pushpin " + "annotcolor={rgb 1 0 0} contents={Get the Kraxi Paper Plane!} display=noprint"; p.create_annotation(left_x, left_y, right_x, right_y, "FileAttachment", optlist); Note that the size of the symbol defined with iconname does not vary; the icon will be displayed in its standard size in the top left corner of the specified rectangle. 3.6.2 Form Fields and JavaScript Button form field for printing. The next example creates a button form field which can be used for printing the document. In the first version we add a caption to the button; later we will use a printer symbol instead of the caption. We start by creating an action of type Named (in Acrobat: Execute a menu item). Also, we must specify the font for the caption: print_action = p.create_action("Named", "menuname=Print"); button_font = p.load_font("Helvetica-Bold", "unicode", ""); The action option for the button form field contains the up event (in Acrobat: Mouse Up) as a trigger for executing the action, plus the print_action handle created above for the action itself. The backgroundcolor {rgb 1 1 0} option specifies yellow background, while bordercolor {rgb 0 0 0} specifies black border. The option caption Print adds the text Print to the button, and tooltip {Print the document} creates an additional explanation for the user. The font option specifies the font using the button_font handle created above. By default, the size of the caption will be adjusted so that it completely fits into the button’s area. Finally, the actual button form field is created with proper coordinates, the name print_button, the type pushbutton and the appropriate options: String optlist = "action {up " + print_action + "} backgroundcolor=yellow " + "bordercolor=black caption=Print tooltip={Print the document} font=" + button_font; p.create_field(left_x, left_y, right_x, right_y, "print_button", "pushbutton", optlist); Now we extend the first version of the button by replacing the text Print with a little printer icon. To achieve this we load the corresponding image file print_icon.jpg as a template before creating the page. Using the icon option we assign the template handle print_icon to the button field, and create the form field similarly to the code above: print_icon = p.load_image("auto", "print_icon.jpg", "template"); if (print_icon == -1) 3.6 Interactive Elements 89
