Gaussian blur moves object when applied in different places in the code?
-
Why does applying a Gaussian blur in different places in the code move the image it applies to? Example code, output, revised code putting the blur call before the 1st image, output.
size(550, 300) # initiate a new image object im = ImageObject() # draw in the image # the 'with' statement will create a custom context # only drawing in the image object with im: # set a size for the image size(200, 200) # draw something fill(1, 0, 0) rect(0, 0, width(), height()) fill(1) fontSize(30) text("Hello World", (10, 10)) # draw in the image in the main context image(im, (10, 50)) # apply some filters im.gaussianBlur() # get the offset (with a blur this will be negative) x, y = im.offset() # draw in the image in the main context image(im, (300+x, 50+y))yields:
size(550, 300) # initiate a new image object im = ImageObject() # draw in the image # the 'with' statement will create a custom context # only drawing in the image object with im: # set a size for the image size(200, 200) # draw something fill(1, 0, 0) rect(0, 0, width(), height()) fill(1) fontSize(30) text("Hello World", (10, 10)) # apply some filters im.gaussianBlur() # draw in the image in the main context image(im, (10, 50)) # get the offset (with a blur this will be negative) x, y = im.offset() # draw in the image in the main context image(im, (300+x, 50+y))yields:

not really a bug: when applying a blur the images gets bigger, check with
im.size()before and after the blur is applied.im.offset()is providing you the correctx,ydifference.
