Combine multiple AmigaFFH objects

Source: R/basic.r, R/bitmapfont.r
c.Rd

Use this function to correctly combine one or more AmigaBitmapFont() class objects into a single AmigaBitmapFontSet() class object, or to combine multiple AmigaBasic() class objects.

Usage

# S3 method for AmigaBasic
c(...)

# S3 method for AmigaBitmapFont
c(..., name = "font")

Arguments

...

Either AmigaBasic() or AmigaBitmapFont() class objects. In case of AmigaBitmapFont() objects: Each AmigaBitmapFont() object should have a unique Y-size.

name

This argument is only valid when ... are one or more AmigaBitmapFont() class objects.

A character string specifying the name that needs to be applied to the font set. When unspecified, the default name 'font' is used. Note that this name will also be used as a file name when writing the font to a file. So make sure the name is also a valid file name. This will not be checked for you and may thus result in errors.

Value

Returns an AmigaBitmapFontSet() in which the AmigaBitmapFont() objects are combined. Or when AmigaBasic()

objects are combined, an AmigaBasic() object is returned in which the lines of Amiga Basic code are combined.

Details

In case ... are one or more AmigaBasic() class objects:

AmigaBasic() class objects are combined into a single AmigaBasic() class object in the same order as they are given as argument to this function. for this purpose the lines of Amiga Basic codes are simply concatenated.

In case ... are one or more AmigaBitmapFont() class objects:

AmigaBitmapFontSet() class objects can hold multiple AmigaBitmapFont() class objects. Use this method to combine font bitmaps into such a font set. Make sure each bitmap represents a unique font height (in pixels). When heights are duplicated an error will be thrown.

You can also specify a name for the font, that will be embeded in the object. As this name will also be used as a file name when writing the font to a file, make sure that it is a valid filename.

Examples

if (FALSE) {
data(font_example)

## first get some AmigaBitmapFont objects:
font8 <- getAmigaBitmapFont(font_example, 8)
font9 <- getAmigaBitmapFont(font_example, 9)

## now bind these bitmaps again in a single set
font.set <- c(font8, font9, name = "my_font_name")

## Amiga Basic codes can also be combined:
bas1 <- as.AmigaBasic("LET a = 1")
bas2 <- as.AmigaBasic("PRINT a")
bas  <- c(bas1, bas2)
}
