Defines properties of AcroForm within PDF document.

A set of flags specifying various document-level characteristics related to signature fields.

Gets the object owning this object.

Gets the collection containing document fields.

Gets a value indicating whether the document contains AcroForm fields.

If set, the document contains at least one signature field. This flag allows a viewer application to enable user interface items (such as menu items or pushbuttons) related to signature processing without having to scan the entire document for the presence of signature fields.

If set, the document contains signatures that may be invalidated if the file is saved (written) in a way that alters its previous contents, as opposed to an incremental update. Merely updating the file by appending new information to the end of the previous version is safe (see Section G.6, “Updating Example”). Viewer applications can use this flag to present a user requesting a full save with an additional alert box warning that signatures will be invalidated and requiring explicit confirmation before continuing with the operation.

Meaningful only if the MaxLen entry is present in the text field dictionary and if the Multiline, Password, and FileSelect flags are clear. If set, the field is automatically divided into as many equally spaced positions, or combs, as the value of MaxLen, and the text is laid out into those combs.

If set, the value of this field should be represented as a rich text string.

If set, the field is a combo box; if clear, the field is a list box.

If set, the combo box includes an editable text box as well as a drop-down list; if clear, it includes only a drop-down list. This flag is meaningful only if the flag is set.

If set, the field’s option items should be sorted alphabetically. This flag is intended for use by form authoring tools, not by PDF viewer applications. Viewers should simply display the options in the order in which they occur in the Opt array.

If set, more than one of the field’s option items may be selected simultaneously; if clear, no more than one item at a time may be selected.

If set, the new value is committed as soon as a selection is made with the pointing device. This option enables applications to perform an action once a selection is made, without requiring the user to exit the field. If clear, the new value is not committed until the user exits the field.

Represents a PDF document. The object model provided by this class follows the PDF 1.7 Reference specification.

To create a PDF document, create an instance of the GcPdfDocument class. Two approaches are possible for adding content and saving the document: Direct mode In this mode, you add pages to the document and draw on them (see below) in arbitrary order. In particular, you can modify pages that have been already created. When done, use or method to save the document. This mode is convenient but uses temporary files, so is somewhat less efficient than sequential mode described next. Sequential mode To use this mode, you call prior to any other operations on the document. You can then add pages and draw on them, but you can only draw on the last (current) page. All content is immediately added to the underlying stream without the use of temporary files. To complete creating the document, you must call . The pages of the document are accessible via the collection. To add content, use property to get a for a page. (In sequential mode, only the currently last page of the document can be drawn on.) You can then use that graphics object to draw the desired content.

The result color is always at least as light as either of the two constituent colors. Screening any color with white produces white; screening with black leaves the original color unchanged. The effect is/ similar to projecting multiple photographic slides simultaneously onto a single screen.

Multiplies or screens the colors, depending on the backdrop color.

Source colors overlay the backdrop while preserving its highlights and shadows. The backdrop color is not replaced but is mixed with the source color to reflect the lightness or darkness of the backdrop.

Selects the darker of the backdrop and source colors.

The backdrop is replaced with the source where the source is darker; otherwise, it is left unchanged.

Selects the lighter of the backdrop and source colors.

The backdrop is replaced with the source where the source is lighter; otherwise, it is left unchanged.

Brightens the backdrop color to reflect the source color. Painting with black produces no change.

Darkens the backdrop color to reflect the source color. Painting with white produces no change.

Multiplies or screens the colors, depending on the source color value.

If the source color is lighter than 0.5, the backdrop is lightened as if it were screened; this is useful for adding highlights to a scene. If the source color is darker than 0.5, the backdrop is darkened; this is useful for adding shadows to a scene. The degree of lightening or darkening is proportional to the difference between the source color and 0.5; if it is equal to 0.5, the backdrop is unchanged. Painting with pure black or white produces pure black or white. The effect is similar to shining a harsh spotlight on the backdrop.

Darkens or lightens the colors, depending on the source color value.

If the source color is lighter than 0.5, the backdrop is lightened as if it were dodged; this is useful for adding highlights to a scene. If the source color is darker than 0.5, the backdrop is darkened as if it were burned in. The degree of lightening or darkening is proportional.

Subtracts the darker of the two constituent colors from the lighter color.

Painting with white inverts the backdrop color; painting with black produces no change.

Produces an effect similar to that of the Difference mode but lower in contrast.

Painting with white inverts the backdrop color; painting with black produces no change.

This mode does not exist in specification but exists in PDF files :(.

Specifies the shape to be used at the ends of open subpaths (and dashes, if any) when they are stroked.

The stroke is squared off at the endpoint of the path. There is no projection beyond the end of the path.

A semicircular arc with a diameter equal to the line width is drawn around the endpoint and filled in.

The stroke continues beyond the endpoint of the path for a distance equal to half the line width and is squared off.

Specifies the shape to be used at the corners of paths that are stroked. Join styles are significant only at points where consecutive segments of a path connect at an angle; segments that meet or intersect fortuitously receive no special treatment.

The outer edges of the strokes for the two segments are extended until they meet at an angle, as in a picture frame. If the segments meet at too sharp an angle (as defined by the miter limit parameter—see “Miter Limit,” above), a bevel join is used instead.

An arc of a circle with a diameter equal to the line width is drawn around the point where the two segments meet, connecting the outer edges of the strokes for the two segments. This pieslice-shaped figure is filled in, producing a rounded corner.

The two segments are finished with butt caps (see “Line Cap Style” on page 216) and the resulting notch beyond the ends of the segments is filled with a triangle.

Defines possible PDF rendering intents.

Colors are represented solely with respect to the light source; no correction is made for the output medium’s white point (such as the color of unprinted paper). Thus, for example, a monitor’s white point, which is bluish compared to that of a printer’s paper, would be reproduced with a blue cast. In-gamut colors are reproduced exactly; out-of-gamut colors are mapped to the nearest value within the reproducible gamut. This style of reproduction has the advantage of providing exact color matches from one output medium to another. It has the disadvantage of causing colors with Y values between the medium’s white point and 1.0 to be out of gamut. A typical use might be for logos and solid colors that require exact reproduction across different media.

Colors are represented with respect to the combination of the light source and the output medium’s white point (such as the color of unprinted paper). Thus, for example, a monitor’s white point would be reproduced on a printer by simply leaving the paper unmarked, ignoring color differences between the two media. In-gamut colors are reproduced exactly; out-of-gamut colors are mapped to the nearest value within the reproducible gamut. This style of reproduction has the advantage of adapting for the varying white points of different output media. It has the disadvantage of not providing exact color matches from one medium to another. A typical use might be for vector graphics.

Colors are represented in a manner that preserves or emphasizes saturation. Reproduction of in-gamut colors may or may not be colorimetrically accurate. A typical use might be for business graphics, where saturation is the most important attribute of the color.

Colors are represented in a manner that provides a pleasing perceptual appearance. To preserve color relationships, both in-gamut and out-of-gamut colors are generally modified from their precise colorimetric values. A typical use might be for scanned images.

Specifies how the intersecting areas of Path objects are combined to form the area of the Path.

Rule that determines whether a point is in the fill region by drawing a ray from that point to infinity in any direction and counting the number of path segments within the given shape that the ray crosses. If this number is odd, the point is inside; if even, the point is outside.

Rule that determines whether a point is in the fill region of the path by drawing a ray from that point to infinity in any direction and then examining the places where a segment of the shape crosses the ray. Starting with a count of zero, add one each time a segment crosses the ray from left to right and subtract one each time a path segment crosses the ray from right to left. After counting the crossings, if the result is zero then the point is outside the path. Otherwise, it is inside.

Defines possible pattern types.

Abstract base class for PDF patterns.

Defines PDF shading pattern.

Defines possible tilling types of the .

Pattern cells are spaced consistently—that is, by a multiple of a device pixel. To achieve this, the application may need to distort the pattern cell slightly by making small adjustments to XStep, YStep, and the transformation matrix. The amount of distortion does not exceed 1 device pixel.

The pattern cell is not distorted, but the spacing between pattern cells may vary by as much as 1 device pixel, both horizontally and vertically, when the pattern is painted. This achieves the spacing requested by XStep and YStep on average but not necessarily for each individual pattern cell.

Pattern cells are spaced consistently as in tiling type 1 but with additional distortion permitted to enable a more efficient implementation.

Sets graphics state.

Saves current graphics state to the stack.

Restores graphics state from the stack.

"Q" Restore the graphics state by removing the most recently saved state from the stack and making it the current state (see “Graphics State Stack” on page 214).

"cm" Modify the current transformation matrix (CTM) by concatenating the specified matrix (see Section 4.2.1, “Coordinate Spaces”). Although the operands specify a matrix, they are written as six separate numbers, not as an array.

"w" Set the line width in the graphics state (see “Line Width” on page 215). It is a non-negative number expressed in user space units; stroking a path entails painting all points whose perpendicular distance from the path in user space is less than or equal to half the line width.

"J" Set the line cap style in the graphics state (see “Line Cap Style” on page 216).

"j" Set the line join style in the graphics state (see “Line Join Style” on page 216).

"M" Set the miter limit in the graphics state (see “Miter Limit” on page 217).

"d" Set the line dash pattern in the graphics state (see “Line Dash Pattern” on page 217).

"ri" (PDF 1.1) Set the color rendering intent in the graphics state (see “Rendering Intents” on page 260).

"i" Set the flatness tolerance in the graphics state (see Section 6.5.1, “Flatness Tolerance”). flatness is a number in the range 0 to 100; a value of 0 specifies the output device’s default flatness tolerance.

"gs" (PDF 1.2) Set the specified parameters in the graphics state. dictName is the name of a graphics state parameter dictionary in the ExtGState subdictionary of the current resource dictionary (see the next section).

"m" Begin a new subpath by moving the current point to coordinates (x, y), omitting any connecting line segment. If the previous path construction operator in the current path was also m, the new moverrides it; no vestige of the previous m operation remains in the path.

"l" Append a straight line segment from the current point to the point (x, y). The new current point is (x, y).

"c" Append a cubic Bézier curve to the current path. The curve extends from the current point to the point (x3 , y3 ), using (x1 , y1 ) and (x2 , y2 ) as the Bézier control points (see “Cubic Bézier Curves,” below). The new current point is (x3 , y3 ).

"v" Append a cubic Bezier curve to the current path. The curve extends from the current point to the point (x3 , y3 ), using the current point and (x2 , y2 ) as the Bézier control points (see “Cubic Bézier Curves,” below). The new current point is (x3 , y3 ).

"y" Append a cubic Bezier curve to the current path. The curve extends from the current point to the point (x3 , y3 ), using (x1 , y1 ) and (x3 , y3 ) as the Bézier control points (see “Cubic Bézier Curves,” below). The new current point is (x3 , y3 ).

"h" Close the current subpath by appending a straight line segment from the current point to the starting point of the subpath. If the current subpath is already closed, h does nothing. This operator terminates the current subpath. Appending another segment to the current path begins a new subpath, even if the new segment begins at the endpoint reached by the h operation.

"re" Append a rectangle to the current path as a complete subpath, with lower-left corner (x, y) and dimensions width and height in user space. The operation x y width height re is equivalent to: x y m (x + width ) y l (x + width ) ( y + height ) l x(y + height ) l h

"S" Stroke the path.

"s" Close and stroke the path. This operator has the same effect as the sequence h S.

"f" Fill the path, using the nonzero winding number rule to determine the region to fill (see “Nonzero Winding Number Rule” on page 232). Any subpaths that are open are implicitly closed before being filled. Also this method executes "F" command. Equivalent to f; included only for compatibility. Although PDF consumer applications must be able to accept this operator, PDF producer applications should use finstead.

"f*" Fill the path, using the even-odd rule to determine the region to fill (see “Even-Odd Rule” on page 233).

"B" Fill and then stroke the path, using the nonzero winding number rule to determine the region to fill. This operator produces the same result as constructing two identical path objects, painting the first with f and the second with S. Note, however, that the filling and stroking portions of the operation consult different values of several graphics state parameters, such as the current color. See also “Special Path-Painting Considerations” on page 569.

"B*" Fill and then stroke the path, using the even-odd rule to determine the region to fill. This operator produces the same result as B, except that the path is filled as if with f* instead of f. See also “Special Path-Painting Considerations” on page 569.

"n" End the path object without filling or stroking it. This operator is a path-painting no-op, used primarily for the side effect of changing the current clipping path (see Section 4.4.3, “Clipping Path Operators”).

"W" Modify the current clipping path by intersecting it with the current path, using the nonzero winding number rule to determine which regions lie inside the clipping path.

"W*" Modify the current clipping path by intersecting it with the current path, using the even-odd rule to determine which regions lie inside the clipping path.

"BT" Begin a text object, initializing the text matrix, Tm , and the text line matrix, Tlm, to the identity matrix. Text objects cannot be nested; a second BT cannot appear before an ET.

"ET" End a text object, discarding the text matrix.

"TL" Set the text leading, Tl , to leading, which is a number expressed in unscaled text space units. Text leading is used only by the T*, ', and " operators. Initial value: 0.

"Tf" Set the text font, Tf , to font and the text font size, Tfs, to size. font is the name of a font resource in the Font subdictionary of the current resource dictionary; size is a number representing a scale factor. There is no initial value for either font or size; they must be specified explicitly by using Tf before any text is shown.

"Tr" Set the text rendering mode, Tmode , to render, which is an integer. Initial value: 0.

"Ts" Set the text rise, Trise, to rise, which is a number expressed in unscaled text space units. Initial value: 0.

"Td" Move to the start of the next line, offset from the start of the current line by (tx , ty ). tx and ty are numbers expressed in unscaled text space units. More precisely, this operator performs the following assignments: | 1 0 0 | Tm = Tlm = | 0 1 0 | * Tlm | tx ty 1 |

"TD" Move to the start of the next line, offset from the start of the current line by (tx , ty ). As a side effect, this operator sets the leading parameter in the text state. This operator has the same effect as the following code: −ty TL tx ty Td

"Tm" Set the text matrix, Tm , and the text line matrix, Tlm: Tm = Tlm = m The matrix specified by the operands is not concatenated onto the current text matrix, but replaces it.

"T*" Move to the start of the next line. This operator has the same effect as the code 0 Tl Td where Tl is the current leading parameter in the text state.

"Tj" Show a text string.

"'" Move to the next line and show a text string. This operator has the same effect as the code: T* str Tj

""" 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 are numbers expressed in unscaled text space units. This operator has the same effect as the following code: aw Tw ac Tc str '

"TJ" Show one or more text strings, allowing individual glyph positioning (see implementation note 58 in Appendix H). Each element of array can be a string or a number. If the element is a string, this operator shows the string. If it is a number, the operator adjusts the text position by that amount; that is, it translates the text matrix, Tm. The number is expressed in thousandths of a unit of text space (see Section 5.3.3, “Text Space Details,” and implementation note 59 in Appendix H). This amount is 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.
