Hi, everyone!
I'd leave from Sendai. At tomorrow(today!?).
...today, I prepared about departure and I studied NSUserDefault class and NSMutableDictionary class.
I thought I can get a feature of "save" and "restore".
But I couldn't it.
NSUserdefault clas is can save and restore a data includes NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary.
I save the UIImage class object, but NSUserDefault class can't save the UIImage class object.
Therefore, I save a NSMutableDictionary class object includes the UIImage classobject.
But I couldn't.
NSUserDefault class could restore the NSMUtableDictionary object, but not UIIMage class object is include the NSMutableDictionary object.

mmm...

After all, I have to translate the UIImage class object to the NSdata class object.
I don't know about it,,,,,..
I'll confer to apple engineer in the WWDC2009.


I'll just have to keep working in the WWDC2009.

Good morning.
I prepared to the WWDC2009.

I proposed a Schedule(reserved a bus, action in Sunfransisco, and more) and prepared a lab session.
I'll have a talk to Apple engineers in lab session.
I made a data for lab session.
Because I'd like to get good answer in lab session, I made the earnest data.


I'll go to lab for I get best answer about problem of a Quartz2D(My application).

And I'll go to User Interface design lab session.
I study about it until attend the WWDC2009.

Good morning.
I studied about UI Design by pdf "iPhone Human Inter face Guidelines
", because I'll attend the "iPhone Interface Design Consulting Lab"
but I couldn't study hard, because I had to do other work.

I read some of pages only...

Good morning !
I solved most of yesterday problem.
I didn't know a content of unknown address at yesterday.
But I could know most of a real identity.
It's alpha value of pixel.
Each values(RGBA) are exist in the each address.
Please see below.
+-----+ _
|alpha| |
+-----+ |
|blue | |
+-----+ Current pixel
|green| |
+-----+ |
|red | |
+-----+ _
|alpha| |
+-----+ |
|blue | |
+-----+ Next pixel
|green| |
+-----+ |
|red | |
+-----+  ̄
| : |
| : |

So, these exist it seem above.
I tried change value of alpha.
But It's not complete.
I could get result see below.
Image1
Image2
Image1+2


These alpha value are 100/255.
About half pixels are transparent.
But remains aren't, more likely, these pixel are seem to broken.
I wouldn't fix it until the WWDC2009 started, because I can't fix it soon.
And I think I should study another that useful for attend WWDC2009.
I took the statistic about differential of touchMoved method count per 10 seconds.
My algorithm of the "Nazca(change name from"YubiFude")" uses three CGLayer objects (depend on the situation, sometime 4layers).
Application speed is slowed by number of layers.
I took the statistic about it.
Result is this.



As a result, application is slowed by increase layer.
It's increase about 20counts per 10seconds.
I'll ask to Apple company member about more good algorithm in WWDC2009.
