incorrectly puts an anchor on the group

oleg

minX,minY,maxX,maxY=application:getLogicalBounds()   centrX = application:getContentWidth()/2 centrY = application:getContentHeight()/2     group1 =Sprite.new() stage:addChild(group1)   logo1=Bitmap.new(Texture.new("img.png")) logo1:setPosition(100,0)   logo2=Bitmap.new(Texture.new("img.png")) logo2:setPosition(300,0)   group1:addChild(logo1) group1:addChild(logo2)   group1:setAnchorPoint(0.5,0) group1:setPosition(centrX,minY)

I want the group1 to be centered
gideros puts the center of the logo1

Why??

oleg

I realized

gideros does not take into account that logo1 x = 100,
and puts an anchor like logo1 x = 0
