indicated in the dialogue box.

2. [ JPEG picture quality ] moving the slider, it sets appropriate value, or inputs value.

When value of JPEG picture quality is set high, picture quality improves, but size of the SWF file becomes large. When in the same

way as the compression setting which is explained with the section before, picture quality is lowered, size of the SWF file

becomes small. Trying various setting, please decide file size and the setting to which picture quality comes to terms.

Vector graphics

With vector graphics, please do not use border as much as possible. By the fact that use of border is restricted, the number of lines

decreases substantially.

Optimization

When the ActionScript is developed in the one for Flash Lite contents which are disposed to the U10, because there is a limit in

the ability of the CPU of the U10, by all means in the general guideline below, therefore.

* As for the ActionScript please make as simple as possible.

The ･ please restrict the number of loops which are used and the quantity of the cord/code which is included in each loop.

* Frame based the loop, it became unnecessary, and others at once please stop.

* The string and please avoid the processing of the arrangement which is emulated. This kind of processing is a possibility of

applying great load on the CPU.

Memo: The Flash 4 ActionScript does not support arrangement. However, the eval () using function, it can emulate arrangement.

Concerning details, Macromedia technical note 14219 the " How to use Eval to emulate an array " (the

www.macromedia.com/go/flash_support (English edition) or the www.macromedia.com/go/flash_support_jp (Japanese edition))

please refer to.

Speed of device and frame several per 1

In case of the project which includes standstill image, almost there are no times when CPU speed of the device becomes problem.

As for the Flash because it is complicated application, with contents development for the U10, compromise is necessary

concerning the important several elements. Until high speed CPU is loaded by the U10, can add to the component inside other

things improvement, devising as much as possible, it is necessary for operation of application that to try does not become slow.

There are no times when it can accept the application which does not do that kind of device.

You do not use wipe, fading in / out, or the animation which reach to the whole picture if possible the sea urchin please do.

Depending upon the contents, when many pixel is renewed at one time, refresh rate decreases. Performance of the Flash

application which it draws up, the number of applications which are opened, active memory capacity, is influenced by CPU speed,

and picture resolution.

Development check list

The occasion where the Flash contents for the U10 are developed, by all means, please check each item below.

* Flash do the contents operate?

* Flash contents are easy to understand the contents, to operate are easy, is?

* Flash do the contents load the data and the SWF file without problem?

* It optimizes image, or rewrites the cord/code, improves performance, file size and it is possible to decrease necessary memory

capacity?
