BitmapWidth/BitmapHeight (function)

Returns the width or height, in inches, of a bitmap image resource, at the specified resolution.

Syntax

Bitmapwidth( name, resolution ) measure value

Bitmapheight( name, resolution ) measure value

Argument

name

String value that specifies the name of the bitmap image resource.

resolution

Integer value that specifies the resolution at which you want to measure the width or height of the bitmap.

Code Sample Example

This example sets the variable maxwidth to the width of the bitmap 'fingerprint' at a resolution of 150 DPI, and the variable

maxheight to the height of the same bitmap at a resolution of 200 DPI.

Example

&maxwidth := bitmapwidth( 'fingerprint', 150 )

&maxheight := bitmapheight( 'fingerprint', 200 )

Cos (function)

Returns the cosine value of the specified angle.

Syntax

cos( value ) measure value

Argument

value

Measure value specifying the angle whose cosine is returned.

Code Sample Example

This example displays a sinusoidal graph.

Example

moveto(0,0)

define(&i,integer,0)

for(&i,1,10,360)

lineto(cos(inttofloat((&i)/ 4)),sin(inttofloat(&i)))
