Make the title something like "Drawing rotated unicode text breaks device contexts on Windows 7." Thanks for being patient. I'm sure Matthew will push a fix very soon. ;) Neil ⊥<div><div class="h5"> On 04/25/2014 06:48 PM, Deren Dohoda wrote: </div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"> Hi Neil, I have the 32-bit version installed on my Win7 machine at home, too. I was able to reproduce my own problem here as well. When I run your example, the first plot looks like I'd expect. The second one does not have the circle. If I remove the \circ from the text-extent it doesn't change anything. If I remove \circ from the text-extent and the draw-text, then the circle appears. If I remove \circ from only draw-text (leaving it in text-extent), the circle also appears. I did take a screenshot if you want to see it. Otherwise, the numbers are 39.0 13.5 2.5 0.0 31.0 13.5 2.5 0.0 I then uninstalled the 32-bit version, downloaded and installed the x86_64 version, and reran your example. The same thing happened again. Something maybe helpful: when the \circ is in the string for draw-text the text is NOT rotated 90 degrees counter-clockwise. When the \circ is removed, the text is drawn rotated 90 degrees counter-clockwise. ...Ah, I see Kieron has uploaded an image to show. That is exactly what I see.

Can you run the following program and reply with what you see? #lang racket (require racket/draw plot) (plot (function sin #e1e-157 #e1e-156)) (define bm (make-bitmap 400 400)) (define dc (make-object bitmap-dc% bm)) (send dc set-smoothing 'smoothed) (send dc set-scale 2 2) (send dc set-font (make-font #:size (plot-font-size) #:family (plot-font-family) #:size-in-pixels? #t)) (send dc get-text-extent "X (⇑∘C)" #f #t 0) (send dc draw-text "X (⇑∘C)" 80 180 #t 0 0) (send dc get-text-extent "Y (∘C)" #f #t 0) (send dc draw-text "Y (∘C)" 10 120 #t 0 (/ pi 2)) (send dc draw-ellipse 30 30 140 140) bm It should produce a simple plot with tick labels on both axes with the superscripted exponent "-157", a collection of numbers that looks something like this: 110.0 13.5 3.0 0.0 34.0 13.5 3.0 0.0 and a bitmap with a circle and the X and Y axis labels you expect, with approximately the placement and orientation you expect them on a plot (though bigger).

The plot frame is generated, the plot title and x-label appear, the tick marks on the axes appear, but the y-label doesn't appear and neither (points ...) nor (function ...) appear. Example code (hopefully the extra characters come through email correctly): #lang racket (require plot) (define (make-p title y-label) (plot (function (λ(x) x)) #:x-min 0 #:x-max 50 #:y-min 0 #:y-max 50 #:x-label "X (⇑∘C)" #:y-label y-label #:title title)) (define-values (works doesnt-work) (values (make-p "Works (⇓∘C)" "Y (C)") (make-p "Doesn't Work (⇓∘C)" "Y (∘C)"))) works doesnt-work ;;;;;;;;;;;;;;;;;;;;; It's not just arbitrary character substitutions, for instance all the \left|right|up|downarrow don't cause any problems, but \Down|Up|etc.arrow causes the same problem as \circ. I threw some in the title and x-label to show that they didn't cause any failures. I've attached an image of what appears in case it helps.
