Memory Leak

[ShareLJM]

In the ObjectC project, when I use the method of"imebra:: DataSet:: getImageAppleModalityTransfirm", there was a memory leak, and then I located it at the bottom of the stack caused by " imebra:: implementation:: memoryPoll:: getMemory".

Imebra has a configurable memory cache that hold some of the de-allocated memory for faster allocation when processing images with the same size.

I should see the code of the client app before considering this as a bug.

NSString filePath = [[NSBundle mainBundle]pathForResource:@"MRBRAIN" ofType:@"DCM"]; ImebraDataSet dataSet = [ImebraCodecFactory loadFromFile:filePath error:nil]; // 获取帧数 ImebraTagId *tagId = [[ImebraTagId alloc] initWithId:ImebraTagNumberOfFrames_0028_0008]; NSUInteger dataSetPage = [dataSet getSignedLong:tagId elementNumber:0 error:nil]; NSLog(@"%lu",(unsigned long)dataSetPage);

self.resultArr = [[NSMutableArray alloc] init];
NSError *appleError;
for (int i =0; i<dataSetPage; i++) {
    @autoreleasepool {
        ImebraImage *image =  [dataSet getImageApplyModalityTransform:i error:&appleError];
        if (appleError) {
            NSLog(@"%u",i);
            break;
        }
        NSString *colorSpace = image.colorSpace;
        uint32_t width = image.width;
        uint32_t height = image.height;
        ImebraTransformsChain *chain =[DicomUtils applyTransformationColorSpace:colorSpace dataSet:dataSet image:image width:width height:height];
        UIImage *img = [DicomUtils generateImage:chain withImage:image];
        [_resultArr addObject:img];
    }
