-Creating browseable SWFs from PDFs
+Notice
 
-   Suppose you have an arbitrary pdf file, "document.pdf". Furthermore,
-   you have downloaded [1]SimpleViewer.swf into the directory where
-   document.pdf lies.
-   Now call:
-   pdf2swf -o tmp.swf document.pdf
-   swfcombine -o flashfile.swf SimpleViewer.swf viewport=tmp.swf 
-   Now, flashfile.swf should be a browseable flash representation of
-   document.pdf which can be embedded into your web page.
-   If you don't know how to embed SWFs into html pages, it's explained at
-   [2]http://www.macromedia.com/support/flash/ts/documents/tn4150.html .
-   (Also, you can simply type
-   swfdump --html flashfile.swf 
-   and insert the output into your html document)
+   This documentation is a little outdated. As with swftools-0.2.1 and
+   above, you can simply do
+   pdf2swf -bl -o document.swf document.pdf 
+   to link viewer and preloader.
+   However, the Steps below are still valid for jpeg2swf. 
    
-Creating JPEG Slideshows
+Step 1: Converting the documents
 
-   You can do the same thing described above with jpeg files. Simply use
+   Suppose you have an arbitrary pdf file, "document.pdf".
+   Call:
+   pdf2swf -o tmp.swf document.pdf 
+   Now, tmp.swf is a Flash Movie generated from document.pdf. Movie means
+   that there are no navigation elements whatsoever. Just frames which
+   get displayed one by one, at a rate of approx. 1/2 frames/second. How
+   to make document browsable is explained below.
+   (You can do the same things described below with jpeg files. Simply
+   use
    jpeg2swf -o tmp.swf pic1.jpeg pic2.jpeg ...
+   and read on)
+   
+Step 2: Linking a viewer
+
+   Just take a viewer of your choice (e.g. [1]SimpleViewer.swf ) and put
+   it in the same directory where you entered the commands above.
+   Now call:
    swfcombine -o flashfile.swf SimpleViewer.swf viewport=tmp.swf 
+   Now, 'flashfile.swf' is "browsable", i.e. there are some buttons in it
+   for turning pages.
    
-Linking a Preloader
+Step 3: Linking a Preloader
 
    Depending on the size of your PDFs/SWFs, you may want to have some
    kind of loading animation displayed while the browser is busy getting
    the actual document. Assuming you have some file like flashfile.swf
-   above, you furthermore need the file [3]PreLoader.swf and an arbirtary
-   loading animation of your choice. (To get started, try [4]loading.swf,
+   above, you furthermore need the file [2]PreLoader.swf and an arbirtary
+   loading animation of your choice. (To get started, try [3]loading.swf,
    or just convert a "Loading" JPEG picture to swf (jpeg2swf -o
    loading.swf picture.jpg)) Now use
-   swfcombine -o flashfilewithloader.swf PreLoader.swf loader=loading.swf
+   swfcombine -o flashfile.swf PreLoader.swf loader=loading.swf
    movie=flashfile.swf 
+   (Most loaders are smaller than the document they load. They usually
+   need some centering so they appear in the middle of the page to be
+   displayed, not in the upper left corner. Replace the above command
+   with e.g.
+   swfcombine -o flashfile.swf PreLoader.swf -x 3000 -y 3000
+   loader=loading.swf movie=flashfile.swf 
+   and try playing around with the values after -x and -y)
+   
+Step 4: Correcting the size and framerate
+
+   Sometimes, the bounding box of the generated flash file is not
+   correct. This happens because when linking a viewer or preloader to
+   the SWFs, the new dimensions are those of the PreLoader and Viewer
+   templates, and not those of your pdf or jpeg files. To fix this, use
+   swfcombine --dummy `swfdump -XY tmp.swf` flashfile.swf -o
+   flashfile.swf 
+   (tmp.swf is your 'original' swf, generated like above)
+   You may also want to adjust the framerate of the movie to that of the
+   preloader. (As the preloader is usually the only animated part of e.g.
+   pdf viewers)
+   Use:
+   swfcombine --dummy `swfdump -r loading.swf` flashfile.swf -o
+   flashfile.swf 
+   
+Step 5: Embedding the SWF into a html page
+
+   Usually, one wants to put the generated SWFs on his web page. To do
+   so, you have to embed the SWF file into html. If you don't know how to
+   embed SWFs into html pages, it's explained at
+   [4]http://www.macromedia.com/support/flash/ts/documents/tn4150.html .
+   Also, you can simply type
+   swfdump --html flashfile.swf 
+   and insert the output into your html document
