plot: Plot AmigaFFH objects

In AmigaFFH: Commodore Amiga File Format Handler

Plot AmigaFFH objects

Description

Plot AmigaFFH objects using base plotting routines.

Usage

## S3 method for class 'AmigaBasicShape'
plot(x, y, ...)

## S3 method for class 'AmigaBitmapFont'
plot(x, y, ...)

## S3 method for class 'AmigaBitmapFontSet'
plot(x, y, ...)

## S3 method for class 'hardwareSprite'
plot(x, y, ...)

## S3 method for class 'IFFChunk'
plot(x, y, ...)

## S3 method for class 'IFF.FORM'
plot(x, y, ...)

## S3 method for class 'IFF.8SVX'
plot(x, y, ...)

## S3 method for class 'IFF.ILBM'
plot(x, y, ...)

## S3 method for class 'IFF.ANIM'
plot(x, y, ...)

## S3 method for class 'SysConfig'
plot(x, y, ...)

## S3 method for class 'AmigaIcon'
plot(x, y, asp = 2, ...)

Arguments

x	An AmigaFFH object to be plotted. See usage section for supported object classes. If x is an AmigaBitmapFont() or AmigaBitmapFontSet() class object, it will plot the full bitmap that is used to extract the font glyphs.
y	When x is an AmigaIcon() class object, y can be used as an index. In that case, when y=1 the first icon image is shown. When y=2 the selected icon image is shown. When x is an AmigaBitmapFontSet() class object, y can be used to plot the bitmap of a specific font height (y). When x is an AmigaBasicShape() class object, y can be used to select a specific layer of the shape to plot, which can be one of "bitmap", "shadow" or "collision".
...	Parameters passed onto the generic graphics plotting routine. When x is an AmigaBitmapFont() or an AmigaBitmapFontSet() object, '...' can also be used for arguments that need to be passed onto the as.raster() function.
asp	A numeric value indicating the aspect ratio for the plot. For many AmigaFFH, the aspect ratio will be based on the Amiga display mode when known. For AmigaIcon() objects a default aspect ratio of 2 is used (tall pixels). When x is an AmigaBitmapFont() or AmigaBitmapFontSet() object, an aspect ratio of 1 is used by default. When the TALLDOT flag is set for that font, the aspect ratio s multiplied by 2. When the WIDEDOT flag is set, it will be divided by 2. A custom aspect ratio can also be used and will override the ratios specified above.

Details

A plotting routine is implemented for most AmigaFFH objects. See the usage section for all supported objects.

Value

Returns NULL silently.

Examples

## Not run: 
## load an IFF file
example.iff <- read.iff(system.file("ilbm8lores.iff", package = "AmigaFFH"))

## and plot it:
plot(example.iff)

## AmigaIcons can also be plotted:
plot(simpleAmigaIcon())

## As can the cursor from a SysConfig object:
plot(simpleSysConfig())

## As can Amiga fonts:
data(font_example)
plot(font_example)
plot(font_example, text = "foo bar", style = "underlined", interpolate = F)

## As can AmigaBasicShapes:
ball <- read.AmigaBasicShape(system.file("ball.shp", package = "AmigaFFH"))
plot(ball)

## End(Not run)
