format

Decompress the module in your sites/all/modules folder.

Go to admin/build/modules (Admin » Site Building » Modules) and select the new module (under package named "Filters input".)

Go to admin/settings/filters (Admin » Site Configuration » Input formats) and select the Insert node filter1.

Make sure that the text areas using the [node:...] tag make use of one of the formats having this Insert node filter ...

• 1. It is suggested that you create a new format if you are to use this filter only on a few pages. This way, you avoid wasting time on all pages.

struct swf_doabc {
	swf_tag			f_tag;		/* 72 or 82 */
	if(f_tag == DoABC) {
		unsigned long	f_action_flags;
		string		f_action_name;
	}
	swf_action3		f_action_record[variable];
};

^*the version specified here is the version in which the tags appeared—however, actions of higher versions can be used with older version tags and thus this version doesn't indicate the version of all the actions used in this tag

The DoABC and DoABCDefine are available since version 9. These are similar to the old DoAction and DoInitAction, yet the actions use a way different declaration scheme and they include flags and a name. This new scheme helps greatly in simplifying the definitions of ECMAScript classes and accelerate the access to the code tremendously.

Note that the ...

struct swf_definevideostream {
	swf_tag			f_tag;		/* 60 */
	unsigned short		f_video_id;
	unsigned short		f_frame_count;
	unsigned short		f_width;	/* WARNING: this is in pixels */
	unsigned short		f_height;
	unsigned char		f_reserved : 5;
	unsigned char		f_deblocking : 2;
	unsigned char		f_smoothing : 1;
	unsigned char		f_codec;
};

This tag defines a video stream. To playback the video stream, one needs to add a list of VideoFrame tags.

The f_width and f_height are defined in pixels. This is rather uncommon in SWF so it is to be noted multiple times.

struct swf_defineedittext {
	swf_tag			f_tag;		/* 37 */
	unsigned short		f_edit_id;
	swf_rect		f_rect;
	unsigned		f_edit_has_text : 1;
	unsigned		f_edit_word_wrap : 1;
	unsigned		f_edit_multiline : 1;

	else {

	}
	if(f_edit_has_color) {
		swf_rgba		f_edit_color;

	if(f_edit_has_max_length) {
		unsigned short		f_edit_max_length;

	if(f_edit_has_layout) {
		unsigned char		f_edit_align;
		unsigned short		f_edit_left_margin;

};

Additional interactivity has been added in V4.0 of the SWF format. This is given by the use of edit boxes offering the end users a way to enter text as if the SWF movie was in fact an interactive form.

The text is defined in a variable (accessible in action scripts). It can be dynamically assigned and retrieved. It is legal to have an empty string as the variable name (not dynamically accessible).

Since version 8, the text drawn by a DefineEditText tag can be tweaked by adding a CSMTextSettings tag.

The f_edit_word_wrap flag will be set to true (1) in order to have words going beyond the ...

When appropriate, images can also be included in SWF files. All the images can be full color and also have an alpha channel.

The coordinates are often transformed with the use of a matrix. The matrix is similar to a transformation matrix in Postscript. It includes a set of scaling factors, rotation angles and translations.

When only the scaling factors are used (no rotation) then these are ratios as one would expect. If a rotation is also applied, then the scaling ratios will be affected accordingly.

Since Flash version 9, actions can be saved in a new format named abcFormat by the Tamarin project from the Mozilla organization.

The code itself (action script) is the same, but the structure of an swf_action3 holds object oriented information about classes, methods and such in a really clean way (really! in comparison to the old way, that's dead clean!).

At this time, the swf_action3 structure is documented in the abcFormat.html file.

I will duplicate and test the structures at a later time.

struct swf_argb {
	unsigned char		f_alpha;
	unsigned char		f_red;
	unsigned char		f_green;
	unsigned char		f_blue;
};

This format was added to be mostly compatible with the old PNG format (XRGB).

struct swf_xrgb {
	unsigned char		f_pad;
	unsigned char		f_red;
	unsigned char		f_green;
	unsigned char		f_blue;
};

Images without an alpha channel which are saved using 32 bits (format 5) use XRGB colors.

The f_pad field should be set to zero or 255.

The color components can be set to any value from 0 (no intensity) to maximum intensity (255).

struct swf_protect {
	swf_tag			f_tag;		/* 24, 58 or 64  */
	if(version >= 5) {
		if(tag == ProtectDebug2) {
			unsigned short	f_reserved;
		}
		/* the password is optional when tag == Protect */
		string		f_md5_password;
	}
};

The protection tag is totally useless. The SWF format is an open format, otherwise how would you have so many players and tools to work with SWF movies? Thus, you can pretend to protect your movies, but anyone with a simple binary editor can transform the tag and make it another which has no such effect. Also, swf_dump and some other tools (such as flasm) can read your movie anyway.

For the sake of defining what you have in each tag, there are the protection tags fully described.

According to Macromedia, you can find some free implementation of the MD5 algorithm by Poul-Henning Kamp in ...
