I am trying to use the zlib based compression for buffer compression. In this case, I am using compress2 function. [CODE]compression_success=compress2((Bytef*)compressed_buffer, &compressed_size,(const Bytef*)package_data.pData, (uLongf)orig_size, 1);[/CODE] And for decompression I am using uncompress function. [CODE]uncompress_success=uncompress((Bytef*)destination, &UnCompSize, (const Bytef*)package_data.pData, package_data.cbData);[/CODE] The problem is that the system tend to be very slow. I …

hello, I have developed a file compression tool using zlib compression library. As the zlib use the deflate and inflate process, does the size of the file effect compression ratio? If it has effect, what is the reason? Thank you.

I am using Rice-Golumb encoding for image compression. Compression and decompression working perfectly on 12-bit greyscale image. The pixels are saved in a short int type array. But when compressing it is saved in a long int type buffer. My question is If the input is short int type then …

I am sorry to bother people with silly questions, But I have no choice. I have a statement unsigned short a=4000, current_word; current_word=a << 3; Then I have another statement unsigned long a=4000, current_word; current_word=a << 19; According to my knowledge they will contain the same value. Am I right?

I have an attachment PDF with pixel alignment. Then I have this code which assigns short integer to appropriate pixels. [CODE] void CMFC3xxDevice::prepare_data_decompress(data_package_ex &pdata) { char *input = (char*) pdata.pData; int incount=pdata.cbData; int finalarray_pos = 0; DWORD dwTempBufferSize = pdata.cbData; for(int i = 0; i < incount; i+=3) { MFC3XXPixelAlignment …

I understood that 0x80000000 is the minimum value for the 32 bit integer for 32 bit machine. If I want the same value for 64 bit machine, what will be the value? Please explain.

I have a void type array. I want to create a function which will read 12 bits in each time and store it in a unsigned int type variable. Any ideas? Thank you.

Hello Everyone, I am trying to work on omage compression on 12 bit image compression. I am using Rice encoding for 12 bit image. I have a complete program for 16 bit image compression. But I want to convert it to 12 bit image compression. And I also want to …

Hello, I have received a piece of code which compress the image direct from a camera to a encoded file using Rice algorithm. [CODE]void code_riceI(unsigned short int *pic, const int X, const int Y, const int n, char *fn) - *pic: pointer to a field of 16bit image (bayer encoded …

Hi, I am trying to use zlib library to use it in a string compression application. Look at the piece of code -- [CODE]uLongf DestBuffSize=0; compress2((Bytef*)CompDataBuff, (uLongf*)&DestBuffSize,(const Bytef*)d1, (uLongf)length, Z_BEST_COMPRESSION); [/CODE] In this code the variable DestBuffSize will contain the length of the compressed buffer. But the variable DestBuffSize is …
