Smart Poke!

 [1/1] from: reboler::ifrance::com at: 28-Dec-2002 11:08

Hi List, In "Easy Draw", Larry Palmiter use this code to display image. do [i: make image! 2x2 poke i 1 red poke i 2 yellow poke i 3 green poke i 4 blue ; make the image 20 times larger i: to-image layout [origin 0x0 image i 40x40] ] Basically after creating a 2 by 2 image, colors are poked in the four available pixels. I thought I could use this to produce fast display. Doing so I encountered something odd.
>> i: make image! 2x2
== make image! [2x2 #{000000000000000000000000}]
>> length? i
== 16
>> poke i 2 white
== make image! [2x2 #{000000FFFFFF000000000000}] Isn't it strange that poke knows that i is a image, and length? does not?
