Version 4 was defined in OpenType 1.5. Version 4 has the same fields as in version 2 and version 3. Although new fields were not added beyond those in version 2 and 3, the specification of certain fields was revised. This metric specifies the distance between the baseline and the approximate height of non-ascending lowercase letters. This metric specifies the distance between the baseline and the approximate height of uppercase letters. This is the Unicode code point, in UTF-16 encoding, of a character that can be used for a default glyph if a requested character is not supported. If the value of this field is zero, glyph Id 0 is to be used for the default character. This is the Unicode code point, in UTF-16 encoding, of a character that can be used as a default break character. The break character is used to separate words and justify text. Most fonts specify U+0020 SPACE as the break character. The maximum distance in glyphs that any feature of this font is capable of effecting. For example kerning has a value of 2 (1 for each glyph in the kerning pair). Fonts with the 'f f i' ligature would have a value of 3. Create a new . Version 5 was defined in OpenType 1.7. Version 5 has two additional fields beyond those in versions 2 - 4. This value is the lower value of the size range for which this font has been designed.

The indices of the standard mac glyph names. Call other subroutine command. Arguments are pushed onto the PostScript interpreter operand stack then the PostScript language procedure at the other subroutine index in the OtherSubrs array in the Private dictionary (or a built-in function equivalent to this procedure) is executed. Calls a subroutine with index from the subroutines array in the Private dictionary. This operator returns the result of dividing num1 by num2. The result is always a real. Pops a number from the top of the PostScript interpreter operand stack and pushes that number onto the operand stack. This command is used only to retrieve a result from an OtherSubrs procedure. Returns from a charstring subroutine and continues execution in the calling charstring. Sets the current point to (x, y) in absolute character space coordinates without performing a charstring moveto command. This establishes the current point for a subsequent relative path building command. The 'setcurrentpoint' command is used only in conjunction with results from 'OtherSubrs' procedures. Brackets an outline section for the dots in letters such as "i", "j" and "!". Declares the vertical ranges of three horizontal stem zones: 1st: between y0 and y0 + dy0 2nd: between y1 and y1 + dy1 3rd: between y2 and y2 + dy2 Where y0, y1 and y2 are all relative to the y coordinate of the left sidebearing point. Suited to letters with 3 horizontal stems like 'E'. Declares the vertical range of a horizontal stem zone between the y coordinates y and y+dy, where y is relative to the y coordinate of the left sidebearing point. Declares the horizontal ranges of three vertical stem zones. 1st: between x0 and x0 + dx0 2nd: between x1 and x1 + dx1 3rd: between x2 and x2 + dx2 Where x0, x1 and x2 are all relative to the x coordinate of the left sidebearing point. Suited to letters with 3 vertical stems, for instance 'm'. Declares the horizontal range of a vertical stem zone between the x coordinates x and x+dx, where x is relative to the x coordinate of the left sidebearing point. Represents the deferred execution of a Type 1 Build Char command. Closes a sub-path. This command does not reposition the current point. Horizontal line-to command. Relative move to for horizontal dimension only. Horizontal vertical curve to command. Draws a Bézier curve when the first Bézier tangent is horizontal and the second Bézier tangent is vertical. Equivalent to dx1 0 dx2 dy2 0 dy3 rrcurveto. Relative rcurveto. Whereas the arguments to the rcurveto operator in the PostScript language are all relative to the current point, the arguments to rrcurveto are relative to each other. Equivalent to: dx1 dy1 (dx1+dx2) (dy1+dy2) (dx1+dx2+dx3) (dy1+dy2+dy3) rcurveto. Relative line-to command. Creates a line moving a distance relative to the current point. Relative move to command. starts a new subpath of the current path in the same manner as moveto. However, the number pair is interpreted as a displacement relative to the current point (x, y) rather than as an absolute coordinate. moveto: moveto sets the current point in the graphics state to the user space coordinate (x, y) without adding any line segments to the current path. If the previous path operation in the current path was also a moveto or rmoveto, that point is deleted from the current path and the new moveto point replaces it. Vertical-horizontal curveto. Equivalent to 0 dy1 dx2 dy2 dx3 0 rrcurveto. This command eliminates two arguments from an rrcurveto call when the first Bézier tangent is vertical and the second Bézier tangent is horizontal. Vertical-line to command. Vertical move to. Moves relative to the current point. Finishes a charstring outline definition and must be the last command in a character's outline (except for accented characters defined using seac). The name hsbw stands for horizontal sidebearing and width; horizontal indicates that the y component of both the sidebearing and width is 0. This command sets the left sidebearing point at (sbx, 0) and sets the character width vector to(wx, 0) in character space. This command also sets the current point to (sbx, 0), but does not place the point in the character path. Sets left sidebearing and the character width vector. This command also sets the current point to(sbx, sby), but does not place the point in the character path. Standard encoding accented character. Makes an accented character from two other characters in the font program. Decodes a set of CharStrings to their corresponding Type 1 BuildChar operations. A charstring is an encrypted sequence of unsigned 8-bit bytes that encode integers and commands. Type 1 BuildChar, when interpreting a charstring, will first decrypt it and then will decode its bytes one at a time in sequence. The value in a byte indicates a command, a number, or subsequent bytes that are to be interpreted in a special way. Once the bytes are decoded into numbers and commands, the execution of these numbers and commands proceeds in a manner similar to the operation of the PostScript language. Type 1 BuildChar uses its own operand stack, called the Type 1 BuildChar operand stack, that is distinct from the PostScript interpreter operand stack. This stack holds up to 24 numeric entries. A number, decoded from a charstring, is pushed onto the Type 1 BuildChar operand stack. A command expects its arguments in order on this operand stack with all arguments generally taken from the bottom of the stack (first argument bottom-most); however, some commands, particularly the subroutine commands, normally work from the top of the stack. If a command returns results, they are pushed onto the Type 1 BuildChar operand stack (last result topmost). The ordered list of numbers and commands for a Type 1 charstring or subroutine. Represents the MinFeature entry which is required for compatibility and is required by the specification to have the value 16, 16. The first value. The second value. The required default value of . Creates a array. The first value. The second value. To distinguish between binary and hex the first 4 bytes (of the ciphertext) for hex must obey these restrictions: The first byte must not be whitespace. One of the first four ciphertext bytes must not be an ASCII hex character. Parse Adobe Type 1 font format. Parses an embedded Adobe Type 1 font file. The bytes of the font program. The length in bytes of the clear text portion of the font program. The length in bytes of the encrypted portion of the font program. The parsed type 1 font. Where an entire PFB file has been embedded in the PDF we read the header first. This is shown briefly in the Type 1 spec but nowhere is it specified what it means or does. An array must begin with either '[' or '{'. An array must end with either ']' or '}'. An Adobe Type 1 font. The name of the font. The encoding dictionary defining a name for each character code. The font matrix. A rectangle in glyph coordinates specifying the font bounding box. This is the smallest rectangle enclosing the shape that would result if all of the glyphs were overlayed on each other. The private dictionary for this font. The charstrings in this font. Create a new . Get the bounding box for the character with the given name. Whether the font contains a character with the given name. Get the pdfpath for the character with the given name. The Private dictionary for a Type 1 font contains hints that apply across all characters in the font. These hints help preserve properties of character outline shapes when rendered at smaller sizes and lower resolutions. These hints help ensure that the shape is as close as possible to the original design even where the character must be represented in few pixels. Note that subroutines are also defined in the private dictionary however for the purposes of this API they are stored on the parent . Optional: Uniquely identifies this font. Optional: Indicates the number of random bytes used for charstring encryption/decryption. Default: 4 Optional: Preserved for backwards compatibility. Must be set if the is 1.
