how to change the thickness of BlackFrame

[Roveeen]

hello, I want to change the thickness of the blackframe，like the following picture:

it's 1/10 of the width (default is 1/4 ).

i cannot really understand CoreAR lib,
I had do something like :
in "codeImageTemplate.c"

---

CRCodeImageTemplate *CRCreateCodeImageTemplate(unsigned char *pixel, int width, int height) {

CRCodeImageTemplate *p = (CRCodeImageTemplate*)malloc(sizeof(CRCodeImageTemplate));

float offsetX = width *1/ 10;
float offsetY = height *1/ 10;

int decodePixelBuff = CRGetDecodePixelBuffWidthHeight();

float samplingWidth = (float)width *8/ 10 / (decodePixelBuff);
float samplingHeight = (float)height*8/ 10 / (decodePixelBuff);
    ....

original：

CRCodeImageTemplate *CRCreateCodeImageTemplate(unsigned char *pixel, int width, int height) {

CRCodeImageTemplate *p = (CRCodeImageTemplate*)malloc(sizeof(CRCodeImageTemplate));

float offsetX = width *1/ 4;
float offsetY = height *1/ 4;

int decodePixelBuff = CRGetDecodePixelBuffWidthHeight();

float samplingWidth = (float)width *1/ 2 / (decodePixelBuff);
float samplingHeight = (float)height*1/ 2 / (decodePixelBuff);
    ....

but it does not work.

can you tell me , how to do?

I'm very grateful.

Uu..
I think that your code is almost OK.
But I don't know what kind of error is happened on your code.
I recommend you should write down raw "decodePixelBuff" value as bitmap file.
