L_BOOL LDicomDS::GetBinaryValue(pElement, pValue, nLength)
pDICOMELEMENT pElement; |
pointer to a DICOMELEMENT structure |
L_VOID * pValue; |
pointer to a buffer |
L_UINT32 nLength; |
length of the buffer |
Updates a buffer with a binary value.
Parameter |
Description |
pElement |
Pointer to a DICOMELEMENT structure within the Data Set. |
pValue |
Buffer that will be updated with the value of the binary value associated with the specified item in the Data Set. You are responsible for allocating the memory for this buffer. |
nLength |
Length, in bytes, of the buffer you allocated. |
TRUE |
The function is able to update the buffer with the binary value. |
FALSE |
The function cannot update the buffer with a binary value. |
Note: You must allocate the memory for pValue.
The DICOMELEMENT structure has a member also called nLength. If this nLength value is greater than the nLength of the buffer you allocated (pValue), then the binary value copied into pValue will be truncated to the smaller length. If the nLength of the DICOMELEMENT is shorter than the nLength of pValue, the entire binary value associated with the DICOMELEMENT will be copied into pValue.
This function can be called for every Value Representation, and it will return the exact value in the Value Field (unconverted).
