Hi, I have not tested this problem on canvas but I'm guessing it would be the same as seen in svg. Part of the value of scalable formats is the lack of granularity and the ability to zoom to the desired resolution. In testing mouse coords on svg I find there is granularity at the scale of the decimal point character. (or one dot of the colon). I have configured Firefox to allow very high zoom levels , this is excellent for looking at my data plots and allows seeing this problem clearly. The mouse cursor moves smoothly as expected but the coord readout only moves in jumps that are the size of the dot. each jump moves the cursor text by a similar amount and updates to coords. Is this due to the svg_scale bug I caught last week? Oops! The dangers of cut-and-paste. That should clearly be SVG_SCALE rather than CANVAS_OVERSAMPLE. Fortunately they are both equal to 10 Ethan Would a higher value of SVG_SCALE increase the resolution here ? Any blow-back? Thx. |
