Hello I'm using plot-snip% objects in my application to display plots. Data and parameters of these plots needs to change based on GUI input. To do that I updated the snip-canvas% object to allow replacing the snip held in the editor-canvas%. Unfortunately, whenever a new snip is inserted, even though I resize the snip to the canvas size, the snip seems to be drawn in three stages: first the snip at its original size is drawn, next, that image appears to be scaled as a bitmap resulting in a blurred image and finally, the image is drawn at the right size and it is sharp.
I uploaded my code here, unfortunately this is the smallest code that can demonstrate the problem. The GitHub GIST also contains screenshots illustrating the behavior. https://gist.github.com/alex-hhh/5defaa52f6c87cbb7ddcf40cc4dd863f My question is, how is the snip-canvas% object supposed to resize the snip such that the snip is only drawn once at the correct size? While for this simple demo, the effect is barely noticeable, in my application it is very noticeable, since the plots have a lot of data and take significant time to redraw.
