Remarks
Reports and Queries

Special cases

Depending on the destination (printer, file, ...), the width returned by iTextWidth may differ (by a tenth of a millimeter) for the same text, displayed in the same font. This difference is caused by the display mechanism used by Windows.

Calculating the width of a text written with fonts of different sizes

You must call iTextWidth for each text that uses a different font.

Calculating the width of a text containing CR characters

iTextWidth ignores the CR characters found in the text. You must call iTextWidth for each line found in the string.

Miscellaneous

A call to iParameter after iTextWidth will have no action because the print job is initialized.
