This tag will be used to specify where and how to place an object in the next frame. The PlaceObject is much different and is presented separately.
The f_depth field is used to indicate at which depth the character is inserted in the current frame. There can be only one object per depth value (thus a maximum of 65536 objects can appear on a single frame).
The f_place_has_move and f_place_has_id_ref flags are used to indicate what to do at the given depth. The following table presents what happens depending on the current value.
f_place_has_move ...
These tags declares a loss-less image bitmap. It has a small header followed by an optional colormap and the bitmap data. When we have a colormap, the bitmap data is an array of indices in the colormap aligned to 4 bytes on a per row basis.
There are three supported formats:
Format
No.
(bits)Color Format Comments Without
AlphaWith
Alpha3
(8 bits(1))RGB ...
The SoundStreamBlock tag defines the data of a sound effect previously defined with a SoundStreamHead or a SoundStreamHead2 tag.
WARNING: This tag requires you to save the swf_tag structure in long format whatever the size of the data (i.e. f_tag_and_size & 0x3F == 0x3F always true even if the size is 62 or less.)
The data depends on the SoundStreamHead[2] definition and is variable in size. Please, see the DefineSound tag for more information about sound data.
The SoundStreamHead[2] tags define a sound effect which is to be loaded with a set of SoundStreamBlock tags. It defines the sound once and for all.
Streaming sound has a strong side effect when playing a movie: it will force a synchronization between the images and the audio. Thus some images may be dropped if the drawing isn't fast enough.
A DefineSound tag declares a set of samples of a sound effect or a music.
The sound samples can be compressed or not, stereo or not and 8 or 16 bits. The different modes are not all available in version 2, although the same tag is used in newer versions with additional capabilities.
The f_sound_is_16bits is always set to 1 (16bits samples) if the samples are compressed (neither Raw
nor Uncompressed
).
The f_sound_rate represents the rate at which the samples are defined. The rate at which it will be played on the target computers may differ. The following equation can be used to determine the ...
The DoAction tag will be used to execute a set of actions in place. Usually, actions are used on buttons to add interactivity to the SWF movies. In version 1 you had only one dynamic branch (WaitForFrame). In version 4 you can test many different things such as a position, angle or sound track cursor position. Since version 5, SWF has a complete scripting language supporting string and arithmetic operations.
This documents makes use of structure definitions that very much look like C structures. It is important to note that this is not all that true since the data saved in a SWF file are very specific and they don't follow the default, inflexible (as in static,) C definitions.
The following pages define the basic types used in this document. The comments explain in more details how each type is used.
Note that except for bit fields, all types start on a byte boundary. Nothing will be aligned on more than one byte.
These tags define an image saved using the JPEG compression scheme.
DefineBitsJPEG (V1.0) does not include the encoding tables which are defined in the unique JPEGTables tag instead. All the DefineBitsJPEG of an SWF file use the only JPEGTables tag. Yes... This means you need a tool that is capable of reusing the same tables over and over again to make sure that all your DefineBitsJPEGs work properly (or use it just once.)
The other tags incorporate their own version of the JPEG encoding tables.
The DefineBitsJPEG3 and DefineBitsJPEG4 support an alpha channel bit plane (8 bits.) ...
We have been running Drupal for some time now and we have noticed that it generates a very large amount of warnings in our log files.
The warning is in link with improperly formatted strings. PostgreSQL tries to follow the SQL specification to the letter and that means you cannot use the backslash character to escape special character sequences (such as \n for a newline character.)
I knew that in most cases the error was generated because of the function saving a full page or some other content in the cache. In that case, the system includes the characters: \012 and \015 (\n and \r.) That ...
