ios - CCRenderTexture anchorPoint or what? -

i need ccrendertexture (white rect) render sprite here (1st picture), render @ lower-left corner (2nd picture). how can change value?

first picture

second picture

rendertextrure.position = ccp(p.x, p.y);

rendertexture.sprite.position = ccp(p.x, p.y);

rendertexture.sprite.anchorpoint = ccp(0.5, 0.5);

edit

ccrendertexture initial position

ccrendertexture size , position in cocos2d-iphone

i found these answers, didn't help. possible change position or not?

check if helps you. note uiimage optional incase want use uiimage.

    ccrendertexture *renderer = [ccrendertexture rendertexturewithwidth:tx height:ty            pixelformat:kcctexture2dpixelformat_rgba8888 depthstencilformat:gl_depth24_stencil8];       [renderer beginwithclear:0 g:0 b:0 a:0 depth:1.0f];      [1st_pic_sprite visit];      [renderer end];      uiimage *img = [renderer getuiimage];
