Passing Array to rsForEach in Renderscript Compute http://stackoverflow.com/questions/10576583/passing-array-to-rsforeach-in-renderscript-compute could do that is by passing in an Allocation that give the offsets within the image data array of the image rows. The v_in argument inside the root will then be the row offset. Since the Allocations the rsForEach call is operating upon is not.. uchar4 gOutPixels void init static const int kBlurWidth 20 This is called per row. The row indices are passed in as v_in or you could also use the x argument and multiply it by image width. void root const int32_t v_in int32_t v_out const void.. are passed in as v_in or you could also use the x argument and multiply it by image width. void root const int32_t v_in int32_t v_out const void usrData uint32_t x uint32_t y float3 blur kBlurWidth float3 cur_colour 0.0f 0.0f 0.0f for int i..
