Cairo pdf example For example, on the pdf() device, we can use the functions Type1Font() to define a new font family, including a new symbol font. The simplest Cairo initializes a new graphics device that uses the cairo graphics library for rendering. This surface collects the elements of your graphic as you apply them The cairo context in this example is tied to an image surface of dimension 120 x 120 and 32 bits per pixel to store RGB and Alpha information. Even though, perhaps some day you actually NEED to resize a Surface (or transform it in any way), so I will briefly describe the rationale used in my alternate answer (already included in the question), deduced after thoroughly reading the docs: The pdftocairo command is a tool that allows users to convert PDF files to various image or document formats using the cairo library. h at master · D-Programming-Deimos/cairo Drawing cairo_t — The cairo drawing context Paths — Creating paths and manipulating path data cairo_pattern_t — Sources for drawing Regions — Representing a pixel-aligned area Transformations — Manipulating the current transformation matrix text — Rendering text and glyphs Raster Sources — Supplying arbitrary image data Tags and Links — Hyperlinks and cairo_surface_t* cairo_pdf_surface_create_for_stream (cairo_write_func_t write_func, void *closure, double width_in_points, double height_in_points); Creates a PDF surface of the specified size in points to be written incrementally to the 文章浏览阅读3. 8, the cairo library is part of the GTK+ system. pdf", type 1228 1229 1230 1231 1232 1233 1234 1235 1236 1237 1238 1239 1240 1241 1242 1243 1244 1245 1246 1247 1248 1249 1250 1251 1252 1253 1254 1255 1256 1257 1258 1259 1260 We can compare the cairo library to the GDI+ library on Windows OS and the Quartz 2D on Mac OS. h in the case of Microsoft Visual C++, Solaris, void cairo_pdf_surface_set_size (cairo_surface_t *surface, double width_in_points, double height_in_points); Changes the size of a PDF surface for the current (and subsequent) pages. grDevices (version 3.
