hey,
i'm hoping someone here has run into this problem before and can
steer me in the right direction. I'm trying to call the following
declare:
vImage_Error vImageMatrixMultiply_Planar8 (
const vImage_Buffer *srcs[],
const vImage_Buffer *dests[],
uint32_t src_planes,
uint32_t dest_planes,
const int16_t matrix[],
int32_t divisor,
const int16_t *pre_bias,
const int32_t *post_bias,
vImage_Flags flags
);
for the most part it doesn't scare me... the same kinda stuff i've
done piles before - but the line const int16_t matrix[] has me
scratching my head. the array i'm trying to pass in is 9 values.
I've built a memoryblock of size 18, and passed it to the declare
as 2 int64 and an int16. i've written the declare as:
declare function vImageMatrixMultiply_Planar8 lib
"Accelerate" (srcs as Ptr, dests as Ptr, src_planes as integer,
dest_planes as integer, matrix1 as int64, matrix2 as int64,matrix3
as int16, divisor as integer, prebias as integer, postbias as
integer, flags as integer) as Integer
however this crashes the app.
I believe const int16_t matrix is just a CONST pointer along the
lines of "const int16_t *pre_bias"
Create a memoryblock and pass it as Ptr should do it I think.
