imageEnabled
Syntax
sprite(whichVectorOrFlashSprite).imageEnabled
the imageEnabled of sprite whichVectorOrFlashSprite
member(whichVectorOrFlashMember).imageEnabled
the imageEnabled of member whichVectorOrFlashMember
Description
Cast member property and sprite property; controls whether a Flash movie or vector shape’s
graphics are visible (TRUE, default) or invisible (FALSE).
This property can be tested and set.
Example
This beginSprite script sets up a linked Flash movie sprite to hide its graphics when it first
appears on the Stage and begins to stream into memory and saves its sprite number in a global
variable called
gStreamingSprite for use in a frame script later in the Score:
global gStreamingSprite
on beginSprite me
gStreamingSprite = me.spriteNum
sprite(gStreamingSprite).imageEnabled = FALSE
end
In a later frame of the movie, this frame script checks to see if the Flash movie sprite specified by
the global variable
gStreamingSprite has finished streaming into memory. If it has not, the
script keeps the playhead looping in the current frame until 100% of the movie has streamed into
memory. It then sets the
imageEnabled property to TRUE so that the graphics appear and lets the
playhead continue to the next frame in the Score.
global gStreamingSprite
on exitFrame me
if sprite(gStreamingSprite).member.percentStreamed < 100 then
go to frame
else
sprite(gStreamingSprite).imageEnabled = TRUE
updatestage
end if
end
imageQuality
Syntax
member(whichMember).imageQuality
the imageQuality of member whichMember
Description
This bitmap cast member property indicates the level of compression to use when the member’s
imageCompression property is set to #jpeg. The range of acceptable values is 0–100. Zero yields
the lowest image quality and highest compression; 100 yields the highest image quality and lowest
compression.
