Image distortion when drawing (fill) over slider

Hi all,


I'm trying to draw a status line (rendered to the left of and following the cursor) the using fill over my slider - however I get a distortion on both the debugger and on the display, any idea what I've done wrong?:

Event code is: "fill 105+h0.val,280,h0.val,10,9777 "


(HMI attached).

maybe your strategy is wrong ...
maybe you are too speedy ...

maybe you are too speedy for your used strategy ...

 

2 fills in one event are better than 3 fills in 3 events


:-)

Hi Gerry,


I've drawn a line on the other side of the cursor which seems to resolve the problem nicely.


One question you may be able to help with - Can you think of a method to separate the maxval from the slider GUI? I would like 255 steps for this program but need 465 for the slider graphics logic :)

fill 100,283,h0.val,3,2991

fill 135+h0.val,283,465-h0.val,3,21130

sorry, but it's not really clear what you want ...  ;-)

Programming is about meeting the requirements.

 - you stated you have a constraint of 465 for the display

 - then this 0 to 464 yields 465 as range, no?

 - you state you want to have 255 steps so range of 0 to 254 is 255

Has the concept of ratios become so outdated, or ?
