WordPerfect® 5.1 for DOS

Problem

Symptoms: Is there a size limit for the extended characters that WordPerfect creates graphically? For example, character 5,30 is not a HP font character, but if the customer uses a 64pt CG Times font, WP will create it graphically and it prints. But if he uses a 65pt CG Times font it does not print. They both will view in View Document. If the same character is created in the Equation Editor, it prints fine even if the point size is 100 or greater. What are the limits? Solutions: When WordPerfect encounters graphic information, it breaks it into bits of data. On a laser printer, this data is gathered in a top to bottom order, one row at a time. This is called rasterization. To rasterize a graphic, WP uses all the available memory (RAM) to rasterize the graphic. If it doesn't find enough memory to rasterize the entire graphic, it slices it up. Each slice will be brought into memory, rasterized, and then swapped to disk as it reads in each slice. If you do not have enough memory to rasterize one row of the graphic information, you will get the error: "Not Enough Memory To Print Graphics." WP is not able slice a .DRS character and rasterize each row of the graphic character. It must rasterize the entire .DRS character in memory. For a 200pt character using 300 dpi (dots per inch) this would be about 86K of RAM needed.

The calculation is as follows: There are 72 points in an inch; 200/72 = 2.78"; The character is 2.78" wide x 2.78" long. Since the character is printed at 300 dpi, that makes (2.78)(300)x(2.78)(300) = 695,556 bits of information. Since 8 bits make up a byte, 695,556/8 = 86,944. This is more than 86K. Rather than have WP give you the error message "Not Enough Memory To Print Graphics," it just won't print the character. Development has requested that this problem be entered as an enhancement to the program. See also Folio memo P51_1866C.
