pango

问题 I have a code uses Cairo and Pango to create an image : #include<stdio.h> #include<cairo.h> #include<pango/pangocairo.h> #define IMAGE_WIDTH 650 #define IMAGE_HEIGHT 150 #define TEXT "HELLO WORLD" #define FONT "MizuFontAlphabet Normal 40" /* * $ gcc $(pkg-config pangocairo cairo --cflags --libs) file.c */ int main(int argc , char** argv) { cairo_surface_t *surface; cairo_t *cr; PangoLayout *layout; PangoFontDescription *desc; PangoRectangle extents; surface = cairo_image_surface_create(CAIRO

问题 After asking my previous question about Uniscribe glyph kerning, and not yet receiving an answer, plus further reading on google etc, it seems Uniscribe may not support extracting glyph kerning information from a font. I therefore have a simple followup question - are there any good examples (preferably with some C++ code) of extracting glyph kerning information for a specified string from a font? It's mentioned in various places that either Pango, QT or ICU are capable of doing this, but

问题 Out of the blue, my Gnuplot has started having issues with the pdfcairo terminal. The font in the produced PDF files is jammed as if the width of the individual characters was set to zero. I am using Gnuplot 5.2.7 on Mac OS, installed via homebrew. Here, a minimal not-working example: reset set terminal pdfcairo set output "mnwe.pdf" set xlabel "Time t" set ylabel "sin(t)" plot [0:2*pi] sin(x) with lines notitle which produces the following output: I suspect that the font issue occurred after

问题 I have simple application that prints text and determines its size in pixels. static void Main(string[] args) { Application.Init(); var screen = Screen.Default; var layout = new Pango.Layout(PangoHelper.ContextGetForScreen(screen)); layout.FontDescription = new FontDescription(); layout.FontDescription.Family = "Times New Roman"; layout.FontDescription.Size = Units.FromPixels(18); layout.SetText("My Text"); int width; int height; layout.GetPixelSize(out width, out height); Console.WriteLine("

Any map I make with: ggplot() + geom_sf() produces the expected map, but does not show the degree sign correctly, as appears from the following picture. The answer given in this answer on SO - degree symbol incorrect in map axis labels - does not help, and I am posting a separate question as I see a different
