# MeasurementWriteText

Write measurement results as readable text

## SYNOPSIS

`#include "dipio_measurement.h"`

dip_Error dipio_MeasurementWriteText ( measurement, fp, options )

## FUNCTION

This function saves/prints the results of a measurement stored in the `measurement` data structure. Since it will save the results to the `fp` FILE pointer (which has to be opened before this function is called, and closed afterwards), the results can be printed to a screen (specify stdout as `fp`) or to a file.

The results are saved in a matrix, with a column for each measurement, and a row for each object. The first column contains the object ID. The `options` structure provides a means to adjust the formatting of the measurement data. Its `separator` variable specifies the column separator character, the rows are separated by a newline. If the `labelAlign` variable is `DIP_TRUE`, the `separator` is repeated such that the columns are aligned. If the `labels` variable is `DIP_TRUE`, the first row contains measurement labels, and `info` specifies whether or not the short description of each measurement function should be printed before the result matrix. If `results` is `DIP_FALSE`, the measurement values are not printed.

## ARGUMENTS

Data type | Name | Description
`dip_Measurement` | `measurement` | Measurement data structure
