Read UL containing multiple values with uint32 about dicomparser HOT 4 CLOSED

Hi Nicolas,

uint32() (and all other dataSet accessors) has an optional second parameter index which lets you access mutli-valued elements. To determine if there is more than one value, you can divide the length of the element by the length of the value. Here is the documentation on uint32() from the source code:

/**
 * Finds the element for tag and returns an unsigned int 32 if it exists and has data
 * @param tag The DICOM tag in the format xGGGGEEEE
 * @param index the index of the value in a multivalued element.  Default is index 0 if not supplied
 * @returns {*} unsigned int 32 or undefined if the attribute is not present or has data of length 0
 */
dicomParser.DataSet.prototype.uint32 = function(tag, index)

from dicomparser.

Thanks -

When you mean "divide by the length of the value", in this case you mean divide 4 (bytes) because it it a uint32, right?

from dicomparser.

Correct, divide by the length in bytes of the value (uint32=4)
