I try to use AWTextureFilter (attached to topic) and got a crash with log:

I think what error is here, line 45 AWTextureFilter.cpp
//Generate Gaussian kernel
radius = MIN(MAX(1,radius), 248);
int kernelSize = 1+radius2;
CCLOG(“AWTextureFilter::blurInput - kernel size: %d”, kernelSize);
int kernel = new int[kernelSize];

I searched this error in Google but there is nothing result.
On iOS it works fine. On Android emulator it crashes.

#2

Can anybody help me? Do I need to link some libs?

#3

Hi,
Could you please provide the missing class (CCTexture2DMutable) so I can test. Did you tried on iOS?
Laurent

#4

OK.
I’m new in C++ and on Android, this Cpp classes aren’t mine.
I test app on Android Emulator (I didn’t have any device) v4.4 and build app with minSdkVersion=“8” and target-19…
I found, that error occurred lately create int array. I’m continuing find a bug.

Code of using AWTextureFilter

    // data is created from CCRenderTexture (with snapshot of base scene node, it's for screenshot) r->newCCImage->getData();
    CCTexture2DMutable* mTex = new CCTexture2DMutable();
    mTex->initWithData(data, tex->getPixelFormat(), width, height, CCSizeMake( width, height));    
    // create filter
    AWTextureFilter *textFilter = new AWTextureFilter();
    CCTexture2DMutable *blurTex = textFilter->blur(mTex, int(0.0125*visibleSize.width), CCRectMake(0, 0, width, height));
    // crash inside this call
#5

I found location of issue. In AWTextureFilter.cpp line
cr+= pixel->r*kernel[i];
I don’t know why it causes crash.

EDIT
Read operation from pixel crashes.

EDIT 2
originalData is not empty, but pixel - does.
It seems like pixel = &originalData[read]; doesn’t work properly.

EDIT 3
I found what index read is below zero on the start of calculations.

#6

I’ve tested on iOS. It does not crash but the texture is black so I’m not sure the blur algorithm woks at all.

    CCImage *image = new CCImage();
    image->initWithImageFile("Icon-114.png");

    CCTexture2DMutable* mTex = new CCTexture2DMutable();
    mTex->initWithImage(image);

    AWTextureFilter *textFilter = new AWTextureFilter();
    CCTexture2DMutable *blurTex = textFilter->blur(mTex, 6);

    layer->addChild(CCSprite::createWithTexture(blurTex));

Note that you have to edit CCTexture2D.h and set the initWithData to virtual

virtual bool initWithData(const void* data, CCTexture2DPixelFormat pixelFormat, unsigned int pixelsWide, unsigned int pixelsHigh, const CCSize& contentSize);
#7

@laurentzubiaur it’s strange, i have it works on iOS fine. Without edit CCTexture2D.h :;qst
After addition some if-conditions into AWTextureFilter like
if(read >= 0) {...
if(yi+xl >= 0) {...
I have worked blur on Android.
Thanks for help!

#8

You’re welcome!
PS: I meant you had to set CCTexture2D::initWithData virtual if you wanted to use initWithImage like I did in my code above.
