ContentStreamBuilder

Intersect the clipping path with the current path using the nonzero winding rule (W). Per the spec, a path-painting operator must follow. Call endPath to clip without also painting the path, e.g. rectangle(...); clip(); endPath().

Like clip, but with the even-odd rule (W*).

Draw image into the rectangle (x, y) → (x+width, y+height) in user space (x, y is the bottom-left corner). Wrapped in its own q … Q so the image transform doesn't leak into later drawing.

Escape hatch: append literal content-stream source, followed by a newline. A Tf, q or Q in it is outside what the builder tracks, so showText keeps encoding for the font it set.

Q, back to the font that the matching save saw; with no matching save, the font stays.

q. The text font is graphics state, which q saves and Q restores (ISO 32000-1, 8.4.2 and 9.3.1), so the font that showText encodes for is saved with it (#733). A font that raw content sets is outside what the builder tracks.

Select an embedded custom font at size. Subsequent showText calls encode their text as Identity-H 2-byte glyph codes for this font, one glyph per character through the font's cmap, in the order of the string. The builder does not shape text: no GSUB substitution, no mark positioning and no bidi reordering, so Arabic letters do not join, marks of Devanagari or Thai do not move into place, and right-to-left text runs left to right. Scripts without those needs, CJK among them, render as written (#750). The font is registered with the owning PdfBuilder on first use.

Tj in the current font: WinAnsi bytes for a standard font, one glyph a character for an embedded one, unshaped (see setFont).

As text, but with an embedded custom font (Identity-H encoded), with no shaping: see setFont.

Convenience: draw a single line of text in font at size, with its baseline at (x, y). Wraps BT/Tf/Td/Tj/ET.

Concatenate a b c d e f onto the current transformation matrix (cm).
