Text in boxes

When text is entered for placement within a box, the system attempts to determine whether the given text exceeds the largest font size that can fit within the boundaries of the box. If FDL computations indicate that the entered text may not fit within the box, the following error message is displayed:

TEXT WILL NOT FIT IN THE BOX

The system checks the horizontal and vertical directions of the box. If an error is detected in one or both directions, an attempt is made to indicate an approximate value for the largest font.

Locating the closest box

When you specify text to be placed in a box, the system locates the closest box within a ten-dot square of the specified point.

Example If text is to be placed in a box located two grid units by two grid units from the origin of the form, the system selects the box closest to this point and within ten dots square. The upper left corner of this box becomes the relative origin for subsequent text placement.

·If text is to be placed in the next box horizontally, FDL begins searching at the upper right corner of the box in which previous text was placed.

·If text is to be placed in the next box vertically, the search begins at the lower left corner.

Error calculations

Horizontal errors The calculations made for horizontal errors (for example, too many characters in a line) are usually accurate. FDL uses the following formula for reporting horizontal errors:

S = P * (B/T)

S target point size

Poriginal font point size B width of the box in dots T width of the text in dots.

Vertical errors The calculation made by FDL for vertical errors (for example too many lines in the box) is a rough approximation of the actual size of text, and the computation may, in fact, be larger than the font for which an error message was displayed. This is because the FDL calculation does not take into account the leading used within the font or provided by line spacing specifications.

The following formula is used by the error-handling routine to compute text size when the box is too small in a vertical direction:

S= (72/300) * (D/N) S target point size

72 number of points in an inch

300 number of dots in an inch

D distance between top and bottom of the box (in dots) N number of lines that are involved.
