FileAttributes

Tag Info
Tag Number: 
69
Tag Type: 
Format
Tag Flash Version: 
8
Brief Description: 

Since version 8, this tag is required and needs to be the very first tag in the movie. It is used as a way to better handle security within the Flash Player.

Tag Structure: 
struct swf_fileattributes {
	swf_tag			f_tag;		/* 69 */
	unsigned		f_reserved : 3;
	unsigned		f_has_metadata : 1;
	unsigned		f_allow_abc : 1;	/* since V9.0 */
	unsigned		f_suppress_cross_domain_caching : 1;	/* since V9.0 */
	unsigned		f_swf_relative_urls : 1;	/* since V9.0 */
	unsigned		f_use_network : 1;
	unsigned		f_reserved : 24;
};

The FileAttributes tag is new to version 8. It must be present in all movies version 8 and over. It must be the very first tag in the SWF movie. It should be unique (other instances will be ignored.)

The f_has_metadata flag shall be set to 1 whenever the movie includes a Metadata tag.

DefineSprite

Tag Info
Tag Number: 
39
Tag Type: 
Define
Tag Flash Version: 
3
Brief Description: 

Declares an animated character. This is similar to a shape with a display list so the character can be changing on its own over time.

Tag Structure: 
struct swf_definesprite {
	swf_tag			f_tag;		/* 39 */
	unsigned short		f_sprite_id;
	unsigned short		f_frame_count;
	...			<data>;
	swf_tag			f_end;
};

A sprite is a set of SWF tags defining an animated object which can then be used as a simple object. A sprite cannot contain another sprite. hHowever, you can use PlaceObject2 to place a sprite in another.

The following are the tags accepted in a Sprite:

Appendix B — History of the SSWF reference

Dec 2, 2009

Moved the monolithic documentation to a multi-page hierarchical document that includes everything we had before plus many links, many terms attached to all pages (tags, English words.) And revision of most of the text for better English and clarification in some places.

Strengthen the formatting with CCK fields so all declarations look alike.

Broken up the actions from one large table to a set of pages.

Started work on the Load() feature of the SSWF library. This helped fixing several small mistakes in the documentation.

About SWF

Brief History

At the very beginning, a company created the SWF format to generate small vector animations on the Internet called Shockwave Flash (hence the name of the format, SWF.) It also included images. This company was bought by Macromedia around 1997 (if I recall properly). This is when Flash v3 was created. Since then, Macromedia created a new version about once a year up to version 8. At that time (in 2005/2006), Macromedia sealed a deal with Adobe which wanted to use the SWF format in their PDF files.

Today (May 1st, 2008), the SWF format is available for free to all. It can be ...

Adding a Table of Contents to a view with parameters

It is possible to add a Table of Contents to a view that has to accept parameters1.

In this case, you do not want to use the solution of including the view in a node (with the Insert view filter, see Can't find doc_table_of_contents_for_views to include!) because then you lose the capability of assigning different parameters to your view (although, if the number of parameters is relatively

  • 1. Note that you need to write some PHP code. If you do not know how to do that, I'm afraid that this won't work for you. You may want to check out the Table of Contents and Insert view solution instead.

CuteMenu has no global settings under the Administer » Site configuration. Instead, the settings are localized in the block and the menu items.

Increase Security with a Reverse Proxy Server

What is Reverse Proxy?

There are three excellent reasons to switch to a Reverse Proxy Server right away:

  1. Protect all of the sensitive data on your servers;
  2. Have only one gateway to the outside world;
  3. Ease the load on your web server by allowing the reverse proxy server to distribute the requests.

Figure 1 below presents a simplified setup of a Reverse Proxy Server.
