Descriptions of SMAF display function and SCAS outline.


Assumption Spec. of the Terminal of which SMAF is Played

Spec. of Display Device (LCD)

LCD size of mobile phone which SMAF file assums is ... its effective display area is about 120 dots width and 130 dots height.

Coordinate of SMAF can be designated by either standard coordinate system, symmetrical coordinate system, or layout coordinate system.

Standard coordinate system settles the origin onto the left upper dot of a terminal LCD. Since symmetrical coordinate system settles the origin onto the right lower dot of a terminal LCD, it is affected by the difference of LCD size. In layout coordinate system, regardless of LCD size, designation of "0" shows the left or upper justify, "63" shows the centering, and "127" shows right or lower justify. By using these coordinate systems for the designation, it becomes possible to create common contents which reduce the influence of LCD size.

[NOTE] For the details about coordinate designation, please refer to SMAF Coordinate Designation

For color indication, the usage of 256 Direct Color of RGB=3:3:2 is assumed. Images in SMAF contents are displayed reducing to this RGB data.


Font Size

Font to be used is system font in terminal. In order to keep the Similarity of contents, playback by some fonts which base on the font size of 12dots width and 13 dots height. In SMAF SCAS, contents are created using 12dots x 13dots font, and are emulated. Although for the strict emulation, it is necessary to use each size of font, each font for terminal has not been implemented in the present condition. Adoption size is assumed as its width to be around 11 to 13, and its character pitch to be around 12 to 14.
Information of terminals which support SMAF Graphic System will be updated.


Display Rewriting Function

Assumption display rewriting timing of mobile phone is about 200 to 300 msec. It differs depending on makers. Also, this value differs according to load. This rewriting time may influence to contents appearance.
