Hi.

For the topic of how components fit together, I preferred an O'Reilly graphic from Power Tools, rather than the onion for training in *nix -- see Figure 1.1 on page 8 (click Browse Contents button on top of book image) at Unix Power Tools, 3rd Edition-O'Reilly Media or see page 5 of the really long PDF O'reilly Unix Unix Power Tools (5.6 Mb) PDF Ebook Download

(I'm not sure I can post it directly from O'Reilly or from the pdf for legal reasons, there may be other sources, and it's possible that O'Reilly might not mind, but I just don't know.)

It was better for me in the pedagogical sense, because I could start with the User block on the whiteboard, and develop the diagram as the topic unfolded. Not much drawing skill was required, thankfully.

One could then discuss development, libraries, etc. -- very open-ended -- with simple block diagrams. Having the students do the drawing as we talked and answered questions helped them see and internalize the big picture -- which is what we called that section ... cheers, drl

$ant = PDF::API2::Annotation->new Returns a annotation object (called from $page->annotation). $ant->link $page, %opts Defines the annotation as launch-page with page $page and options %opts (-rect, -border or 'dest-options'). $ant->url $url, %opts Defines the annotation as launch-url with url $url and options %opts (-rect and/or -border). $ant->file $file, %opts Defines the annotation as launch-file with filepath $file and options %opts (-rect and/or -border). $ant->pdfile $pdfile, $pagenum, %opts Defines the annotation as pdf-file with filepath $pdfile, $pagenum and options %opts (same as dest). $ant->text $text, %opts Defines the annotation as textnote with content $text and options %opts (-rect and/or -open). $ant->movie $file, $contentype, %opts Defines the annotation as a movie from $file with $contentype and options %opts (-rect). $ant->rect $llx, $lly, $urx, $ury Sets the rectangle of the annotation. $ant->border @b Sets the border-styles of the annotation, if applicable. $ant->content @lines Sets the text-content of the annotation, if applicable. $ant->open $bool Display the annotation either open or closed, if applicable. $ant->dest( $page, -fit => 1 ) Display the page designated by page, with its contents magnified just enough to fit the entire page within the window both horizontally and vertically. If the required horizontal and vertical magnification factors are different, use the smaller of the two, centering the page within the window in the other dimension. $ant->dest( $page, -fith => $top ) Display the page designated by page, with the vertical coordinate top positioned at the top edge of the window and the contents of the page magnified just enough to fit the entire width of the page within the window. $ant->dest( $page, -fitv => $left ) Display the page designated by page, with the horizontal coordinate left positioned at the left edge of the window and the contents of the page magnified just enough to fit the entire height of the page within the window. $ant->dest( $page, -fitr => [ $left, $bottom, $right, $top ] ) Display the page designated by page, with its contents magnified just enough to fit the rectangle specified by the coordinates left, bottom, right, and top entirely within the window both horizontally and vertically. If the required horizontal and vertical magnification factors are different, use the smaller of the two, centering the rectangle within the window in the other dimension. $ant->dest( $page, -fitb => 1 ) (PDF 1.1) Display the page designated by page, with its contents magnified just enough to fit its bounding box entirely within the window both horizontally and vertically. If the required horizontal and vertical magnification factors are different, use the smaller of the two, centering the bounding box within the window in the other dimension. $ant->dest( $page, -fitbh => $top ) (PDF 1.1) Display the page designated by page, with the vertical coordinate top positioned at the top edge of the window and the contents of the page magnified just enough to fit the entire width of its bounding box within the window. $ant->dest( $page, -fitbv => $left ) (PDF 1.1) Display the page designated by page, with the horizontal coordinate left positioned at the left edge of the window and the contents of the page magnified just enough to fit the entire height of its bounding box within the window. $ant->dest( $page, -xyz => [ $left, $top, $zoom ] ) Display the page designated by page, with the coordinates (left, top) positioned at the top-left corner of the window and the contents of the page magnified by the factor zoom. A zero(0) value for any of the parameters left, top, or zoom specifies that the current value of that parameter is to be retained unchanged. $ant->dest( $name ) (PDF 1.2) Connect the Annotation to a "Named Destination" defined elswere.
