Operations

Preliminary mark

The list of operations contains all operations as defined in the PDF Specification that are used in PDF.js, aside with the operations that are only defined by PDF.js. The first group of operations show the operator, operands and description as defined in the PDF Specification. In the second group I tried to describe the operations as good as possible.

  • size: number

PDF Specification

Set the text font to font and the text font size to size. font shall be the name of a font resource in the Font subdictionary of the current resource dictionary; size shall be a number representing a scale factor.

40: moveText (Td)

Operands

  • tx: number
  • ty: number

PDF Specification

Move to the start of the next line, offset from the start of the current line by (tx, ty). tx and ty shall denote numbers expressed in unscaled text space units. More precisely, this operator shall perform these assignments:

           ⎡ 1  0  0 ⎤
Tm = Tlm = ⎢ 0  1  0 ⎥ ⨯ Tlm
           ⎣ tx ty 1 ⎦

           ⎣ c f 1 ⎦

Tm  = text matrix
Tlm = text line matrix

The operands shall all be numbers, and the initial value for Tm and Tlm shall be the identity matrix, [ 1 0 0 1 0 0 ]. Although the operands specify a matrix, they shall be passed to Tm as six separate numbers, not as an array.

The matrix specified by the operands shall not be concatenated onto the current text matrix, but shall replace it.

Source

Operands

none

PDF Specification

Move to the start of the next line. This operator has the same effect as the code

0 -Tl Td

where Tl denotes the current leading parameter in the text state. The negative of Tl is used here because Tl is the text leading expressed as a positive number. Going to the next line entails decreasing the y coordinate.

Source

44: showText (Tj)

Operands

Operands differ between the PDF specification and the implementation in PDF.js.

  • string: string (PDF Specification)
  • glyphs: array (implementation in PDF.js)

PDF Specification

Show a text string.

Source

45: showSpacedText (TJ)

Operands

  • array: ?

PDF Specification

Show one or more text strings, allowing individual glyph positioning. Each element of array shall be either a string or a number. If the element is a string, this operator shall show the string. If it is a number, the operator shall adjust the text position by that amount; that is, it shall translate the text matrix, Tm. The number shall be expressed in thousandths of a unit of text space. This amount shall be subtracted from the current horizontal or vertical coordinate, depending on the writing mode. In the default coordinate system, a positive adjustment has the effect of moving the next glyph painted either to the left or down by the given amount.

Source

46: nextLineShowText (')

Operands

Operands differ between the PDF specification and the implementation in PDF.js.

  • string: string (PDF Specification)
  • glyphs: array (implementation in PDF.js)

PDF Specification

Move to the next line and show a text string. This operator shall have the same effect as the code

string Tj

Source

47: nextLineSetSpacingShowText (")

Operands

Operands differ between the PDF specification and the implementation in PDF.js.

  • aw: number (same)
  • ac: number (same)
  • string: string (PDF Specification)
  • glyphs: array (implementation in PDF.js)

PDF Specification

Move to the next line and show a text string, using aw as the word spacing and ac as the character spacing (setting the corresponding parameters in the text state). aw and ac shall be numbers expressed in unscaled text space units. This operator shall have the same effect as this code:

aw Tw
ac Tc
string '

Source

48: setCharWidth (d0)

Operands

  • wx: number
  • wy: number

PDF Specification

Set width information for the glyph and declare that the glyph description specifies both its shape and its colour.

wx denotes the horizontal displacement in the glyph coordinate system; it shall be consistent with the corresponding width in the font’s Widths array. wy shall be 0.

This operator shall only be permitted in a content stream appearing in a Type 3 font’s CharProcs dictionary. It is typically used only if the glyph description executes operators to set the colour explicitly.

Source

49: setCharWidthAndBounds (d1)

Operands

  • wx: number
  • wy: number
  • llx: ?
  • lly: ?
  • urx: ?
  • ury: ?

PDF Specification

Set width and bounding box information for the glyph and declare that the glyph description specifies only shape, not colour.

wx denotes the horizontal displacement in the glyph coordinate system; it shall be consistent with the corresponding width in the font’s Widths array. wy shall be 0.

llx and lly denote the coordinates of the lower-left corner, and urx and ury denote the upper-right corner, of the glyph bounding box.

The glyph bounding box is the smallest rectangle, oriented with the axes of the glyph coordinate system, that completely encloses all marks placed on the page as a result of executing the glyph’s description. The declared bounding box shall be correct—in other words, sufficiently large to enclose the entire glyph. If any marks fall outside this bounding box, the result is unpredictable.

A glyph description that begins with the d1 operator should not execute any operators that set the colour (or other colour-related parameters) in the graphics state; any use of such operators shall be ignored. The glyph description is executed solely to determine the glyph’s shape. Its colour shall be determined by the graphics state in effect each time this glyph is painted by a text-showing operator. For the same reason, the glyph description shall not include an image; however, an image mask is acceptable, since it merely defines a region of the page to be painted with the current colour.

This operator shall be used only in a content stream appearing in a Type 3 font’s CharProcs dictionary.

Source

50: setStrokeColorSpace (CS)

Operands

  • name: string

PDF Specification

Set the current colour space to use for stroking operations. The operand name shall be a name object. If the colour space is one that can be specified by a name and no additional parameters (DeviceGray, DeviceRGB, DeviceCMYK, and certain cases of Pattern), the name may be specified directly. Otherwise, it shall be a name defined in the ColorSpace subdictionary of the current resource dictionary; the associated value shall be an array describing the colour space.

The names DeviceGray, DeviceRGB, DeviceCMYK, and Pattern always identify the corresponding colour spaces directly; they never refer to resources in the ColorSpace subdictionary.

The CS operator shall also set the current stroking colour to its initial value, which depends on the colour space:

  • In a DeviceGray, DeviceRGB, CalGray, or CalRGB colour space, the initial colour shall have all components equal to 0.0.
  • In a DeviceCMYK colour space, the initial colour shall be [ 0.0 0.0 0.0 1.0 ].
  • In a Lab or ICCBased colour space, the initial colour shall have all components equal to 0.0 unless that falls outside the intervals specified by the space’s Range entry, in which case the nearest valid value shall be substituted.
  • In an Indexed colour space, the initial colour value shall be 0.
  • In a Separation or DeviceN colour space, the initial tint value shall be 1.0 for all colorants.
  • In a Pattern colour space, the initial colour shall be a pattern object that causes nothing to be painted.

PDF Specification

Set the colour to use for stroking operations in a device, CIE-based (other than ICCBased), or Indexed colour space. The number of operands required and their interpretation depends on the current stroking colour space:

  • For DeviceGray, CalGray, and Indexed colour spaces, one operand shall be required (n = 1).
  • For DeviceRGB, CalRGB, and Lab colour spaces, three operands shall be required (n = 3).
  • For DeviceCMYK four operands shall be required (n = 4).

If the current stroking colour space is a Pattern colour space, name shall be the name of an entry in the Pattern subdictionary of the current resource dictionary. For an uncoloured tiling pattern (PatternType = 1 and PaintType = 2), c1 ... cn shall be component values specifying a colour in the pattern’s underlying colour space. For other types of patterns, these operands shall not be specified.

Source

62: shadingFill (sh)

Operands

  • name: string

PDF Specification

Paint the shape and colour shading described by a shading dictionary, subject to the current clipping path. The current colour in the graphics state is neither used nor altered. The effect is different from that of painting a path using a shading pattern as the current colour.

name is the name of a shading dictionary resource in the Shading subdictionary of the current resource dictionary. All coordinates in the shading dictionary are interpreted relative to the current user space. (By contrast, when a shading dictionary is used in a type 2 pattern, the coordinates are expressed in pattern space.) All colours are interpreted in the colour space identified by the shading dictionary’s ColorSpace entry. The Background entry, if present, is ignored.

This operator should be applied only to bounded or geometrically defined shadings. If applied to an unbounded shading, it paints the shading’s gradient fill across the entire clipping region, which may be time-consuming.

91: constructPath

Operands

Description

Represents a collection of path construction operations. Is there because of speed optimization so paths can be drawn in a batch.

Example

{
  "ops": [ 19, 13, 14 ],
  "args": [ 0, 0, 5, 6, 6, 0, 4, 3 ],
}

This would draw a rectangle (19) from the point (0, 0) with a width of 5 and a height of 6, than move the cursor (13) to the point (6, 0) and afterwards draw a line (14) from this point to the point (4, 3):

  • rectangle: [ 0, 0, 5, 6 ]
  • moveTo: [ 6, 0 ]
  • lineTo: [ 4, 3 ]
