HALFTONE SCALER

version 2.0

02/90

Camera and production personnel in the offset lithography field must often

re-size photographs to fit designated 'windows' on art boards. The tools

available for this task have proven unsatisfactory. The traditional

proportion wheel allows using the familiar inch-and-fraction system, but is

awkward and prone to error. Handheld calculators are convenient and

accurate, but require converting fractions to decimal or using picas instead

of inches. There is a real need for a system that permits working with

inches and fractions, with direct entry of fractions, that gives rounded off

percentage reduction and enlargement, and that automatically checks the other

dimension of the halftone for size. These very features characterize this

program.

---------

This version of the program permits fractional and decimal input. Enter

fractions in the form A B/C, where A, B, and C are whole numbers and there is

a space or two between the number and the fractional part. Examples of valid

fraction inputs are: 3 7/8, 14 13/32, 17/64. Decimals may be entered as

usual, such as 3.25, 11.063, .125, and so forth. Entering just whole numbers

is also allowed. Mixing fractions and decimals within any single entry will

give a false result, for example 17 1.5/16. Using fractions and decimals on

alternate entries is permitted, however. Example: enter 1.5 on 'original

size' and 7/16 on 'final size'.

As the program begins you are given the option of activating the feature that

automatically calculates what the other side of the HT will go to at the

calculated reduction or enlargement. This is especially useful if the HT

must trap to rules or fit an exact size window. Note that this calculation

is 'automatically' rounded DOWN to the nearest fractional part as a safety

feature.

The program terminates when you indicate that you have no more HT's to scale.

----------

This is the second version of the program. The input and display have been

improved considerably from the preliminary version. There is no doubt still

room for improvement, and I will consider upgrading the program if there is

demand for it.

Try out the program, and if it saves you time and money in your business or

application, please send me a small (suggested $3.00) contribution. I need

the money to buy more computer books.

Send suggestions, praise, and brickbats to:

The program was developed with the Mix C compiler (old version). Even though

I checked for errors, I can take no responsibility for any incidental

damages caused by its use.
