I noticed a few issues for my use case with the UDF one being that adding a sample required updating the waveform
High CPU usage went hand in hand with that requirement
Another issue was just how long updating took to complete
I've hopefully rectified that with this version
 
There are a few changes (only 1 line per graph for instance)
The addition of a function AddSample (uses graphics paths to speed up drawing samples on update) Gridlines are only generated once A sample finished line can be added UpdateGraph allows you to compress the discarded portion of the graph (it looks kinda cool but uses more CPU) Lower Cpu usage Uses real Control Ids - it is a label control underneath so you get click events and can display text when control is disabled Example (Waveform.au3)

hello autoit team
please i've a question for you.
am creating a audio player
and in this audio player i want to show the current trac info
such as the total time and the position ... etc
i know i can show it as label
but the screen reader for the blind read the text every change
because it have a screen scan
what i want is to show this informations but such image or icon
i mean i need to create
GUICtrlCreatepic or GUICtrlCreateicon ....
or some thing as that
and show this informations as image on it
i think that i can do that with the 
_GDIPlus functions
but i couldn't find the currect way to do it
i tried the _GDIPlus_GraphicsDrawString
but i couldn't know how it work
what i need is a small example that create a GUI
and add a multy line text to it as graphic or image.
so i need a simple way because it will changed every sec
i hope any one can help me to do that
global $GUI = GUICreate("text", 400, 400) global $label = GUICtrlCreateLabel(GetText(), 10, 10, 380, 380) GUISetState() do sleep(100) until GUIGetMSG() = -3 exit func GetText() return StringFormat("file name is test.mp3 \r\n total time is 00:30:00 \r\n position is 00:05:50") endFunc  

I was inspired by a CSS example to create a procedural graphic without any shader or ray tracing technique.
Here the result using GDI+ only:

I hope you like it.
 
Feel free to post your examples here, too. 

So I don't have any code cooked up yet as this is still in the theoretical stage. Just looking for some advice.
My current idea is to resize the image to 1x1 pixel, probably using _GDIPlus_ImageResize, and read the color of the resulting pixel to obtain an admittedly very general sense of brightness. Does anyone think this could work?
We have a CCTV system running at home using some home made cameras (raspberry pi) and we're trying to automate toggling settings for day/night time. We started with an AutoIt script that checked sunrise and sundown times for our location (calculations pulled from here) and toggled the settings based on that. Unfortunately our weather varies wildly, so it can get light/dark far outside normal sunrise/sundown times. Now we're hoping to periodically grab a still from the camera and toggle the light mode based on that.
