Hi, I've been trying to cooperate with guile-cairo. However, the documentation serves as a reference rather than a tutorial, and I've been trying to agree the tutorial from the Cairo website with guile bindings, to no avail.
After evaluating the following code, the svg (or pdf) file gets generated, but it is (in both cases) completely blank. The textual content of the svg and pdf files suggests that the drawing commands have indeed been issued, but apparently something's wrong. (cairo-version) reports 11406. So, here comes the code (based on the first snippet in the "Drawing with Cairo" section from https://cairographics.org/tutorial/). Note (BUG) by the way, that the order of arguments to cairo-*-surface-create is reversed compared to the documentation, which claims that the output file name should come first. (use-modules (cairo)) (define s (cairo-svg-surface-create 200 300 "test.svg")) ;;(define s (cairo-pdf-surface-create 300.0 200.0 "test.pdf")) (define c (cairo-create s)) (cairo-set-source-rgb c 0 0 0) (cairo-move-to c 0 0) (cairo-line-to c 1 1) (cairo-move-to c 1 0) (cairo-line-to c 0 1) (cairo-set-line-width c 0.2) (cairo-stroke c) (cairo-rectangle c 0 0 0.5 0.5) (cairo-set-source-rgba c 1 0 0 0.80) (cairo-fill c) (cairo-rectangle c 0 0.5 0.5 0.5) (cairo-set-source-rgba c 0 1 0 0.60) (cairo-fill c) (cairo-rectangle c 0.5 0 0.5 0.5) (cairo-set-source-rgba c 0 0 1 0.40) (cairo-fill c) (cairo-surface-finish s)
