Using Fonts
Note: Similarly for PCL printers, the HP printer definition file
(glue file) is loaded and all the fonts defined in the file are also
loaded. While looking for a font, Oracle Reports searches for an
entry in the HPD file with the font name and accordingly takes the
font if the TFM file for this font is also found. Otherwise, Oracle
Reports matches this font to the closest available one.
Once the list of available fonts is generated, the mapped font is searched for in this list
of fonts and, again, the AFM files are read for the purpose of calculating the text size
and weight.
Substituting fonts
If a particular font is needed but not found in the PPD file or if an AFM file is not
found, Oracle Reports will look for the nearest matching font according to its matching
rules. For example, suppose a report is originally designed with a Korean font SimSun
and in the uifont.ali file no mapping for this font is found. Oracle Reports will
look for the font SimSun in the list of available fonts generated by the Font lookup
algorithm. If this font name is not in that list, Oracle Reports tries to look for the closest
matching font from the list of fonts given in the printer definition file.
For the SimSun font, the character set is 850. If it cannot find any matching font for this
character set, Oracle Reports searches for a font that has a character set for the
environment in which the application is running. After a set of fonts with a similar
character set is found, Oracle Reports picks the closest match to the requested font
based on the font weight, style, etc. If more than one font has the same parameters,
Oracle Reports picks the first one and uses it instead of the original font.
Font matching rules
When attempting to match a font, Oracle Reports will try to find the closest match
according to the following criteria for fonts with the same character set:
fontface > fontsize > fontstyle > fontweight > fontwidth
If Oracle Reports can't match the font face, it will try to match the font size; if it can't
match the size, it will try to match the font style; and so on.
If a font matches the font size but nothing else and another font matches the style,
weight, and width but not the font size, then Oracle Reports will pick the font with the
same font size.
It should be noted that irrespective of any font in the output file, the final printed
output will depend solely on the fonts installed in the printer.
Example: Suppose that a report has layout objects associated with one of two fonts,
Helvetica font of size 8, style Plain, and weight Medium, and Courier font. If the user
is running this report on a PostScript-1 printer and generating HTML output, the fonts
are chosen as follows:
1. While formatting, Oracle Reports checks uifont.ali for any mappings of either
specified font. Suppose that uifont.ali contains this entry in the
[Printer:PostScript1] section:
Helvetica.8.Plain.Medium.. = "Mkai-Medium"..
Oracle Reports will now search for the Mkai-Medium font instead of the Helvetica
font.
