AviSynth Syntax - Conversion functionsΒΆ

Conversion functions convert between different types. There are also some numeric functions that can be classified in this category, namely: Ceil, Floor, Float, Int and Round.

  • Value | v2.07 | Value(string)

Converts a decimal string to its associated numeric value.

Examples:

Value ("-2.7") = -2.7
  • HexValue | v2.07 | HexValue(string)

Converts a hexadecimal string to its associated numeric value.

Examples:

HexValue ("FF00") = 65280
  • Hex | v2.60 | Hex(int)

Converts a numerical value to its hexadecimal value string. See Colors for more information on specifying colors.

Examples:

Hex (10824234) = "A52A2A"
  • String | v2.07 | String(float / int [, string format_string])

Converts a variable to a string. If the variable is float or integer, it first converts it to a float and then uses format_string to convert the float to a string. The syntax of format_string is as follows:

  • %[flags][width][.precision]f

    • width: the minimum width (the string is never truncated)

    • precision: the number of digits printed

    • flags:

      • - left align (instead right align)

      • + always print the +/- sign

      • 0 padding with leading zeros

      • ' ' print a blank instead of a "+"

      • # always print the decimal point

You can also put arbitrary text around the format_string as defined above, similar to the C-language printf function.

Examples:

Subtitle( "Clip height is " + String(last.height) )
Subtitle( String(x, "Value of x is %.3f after AR calc") )
Subtitle( "Value of x is " + String(x, "%.3f") + " after AR calc") )
# same as above
String(1.23, "%f") = '1.23'
String(1.23, "%5.1f") = ' 1.2'
String(1.23, "%1.3f") = '1.230'
String(24, "%05.0f") = '00024'
