Pango::Cairo(3)

Pango::Cairo(3) but make it make sense 💅

okay so bestie, this is the Pango::Cairo(3) page from the User Contributed Perl Documentation. it's literally the glue between Pango (the text layout queen) and Cairo (the drawing icon), and i'm gonna walk you through every single method so you can slay your rendering game. no cap, let's get into it. ✨

---

✨ METHODS ✨

layout = Pango::Cairo::create_layout ($cr)

makes you a fresh new layout tied to that cairo context. main character energy fr.

• $cr — a Cairo::Context, the canvas bestie we're all drawing on 🎨

---

Pango::Cairo::error_underline_path ($cr, $x, $y, $width, $height)

builds the path for that squiggly error underline. you know the vibe — the little red wiggle under a typo. it's giving "your code has issues" but make it art.

• $cr — a Cairo::Context 🖌️
• $x — a double, the x coord
• $y — a double, the y coord
• $width — a double, how wide
• $height — a double, how tall

Since: pango 1.14 🫶

---

Pango::Cairo::glyph_string_path ($cr, $font, $glyphs)

adds the path for a whole glyph string to the context. this is the "draw the letters as outlines" moment. lowkey iconic.

• $cr — a Cairo::Context 🌈
• $font — a Pango::Font, the font doing the heavy lifting
• $glyphs — a Pango::GlyphString, all the glpyhs in a cute little row

---

Pango::Cairo::layout_line_path ($cr, $line)

path-ifies one single line of a layout. one line, one vibe, one path. periodt.

• $cr — a Cairo::Context 🎀
• $line — a Pango::LayoutLine, the line in question

---

Pango::Cairo::layout_path ($cr, $layout)

now we're doing the WHOLE layout as a path. every line, all at once. highkey satisfying.

• $cr — a Cairo::Context 🦋
• $layout — a Pango::Layout, the full layout

---

Pango::Cairo::show_error_underline ($cr, $x, $y, $width, $height)

same squiggly error underline energy as above, but this one draws it directly instead of just making a path. instant gratification, no waiting. 💀

• $cr — a Cairo::Context ✏️
• $x — a double
• $y — a double
• $width — a double
• $height — a double

Since: pango 1.14 🫶

---

Pango::Cairo::show_glyph_string ($cr, $font, $glyphs)

draws the glyph string straight onto the context. no path middleman, we're going direct. slay.

• $cr — a Cairo::Context 💖
• $font — a Pango::Font
• $glyphs — a Pango::GlyphString

---

Pango::Cairo::show_layout ($cr, $layout)

renders the entire layout right there on the context. the full text, all of it, rendered. obsessed. 🔥

• $cr — a Cairo::Context 🎨
• $layout — a Pango::Layout

---

Pango::Cairo::show_layout_line ($cr, $line)

just one line of the layout, drawn directly. sometimes you only need a little snack, not the whole meal. 🍓

• $cr — a Cairo::Context ✨
• $line — a Pango::LayoutLine

---

Pango::Cairo::update_context ($cr, $context)

syncs your cairo context's font options and stuff over to the pango context. keeping them on the same page, as besties do. 🫶

• $cr — a Cairo::Context 💜
• $context — a Pango::Context

---

Pango::Cairo::update_layout ($cr, $layout)

updates a layout with whatever the cairo context is doing. keeps your layout vibing correctly with the graphics context. no cap.

• $cr — a Cairo::Context 🌸
• $layout — a Pango::Layout
