Thanks for sharing. What are you using it for, or intending to use it for? To me, the menu buttons seemed useful - is that something you have done or is it coming from elsewhere and you just included it because it looks good?

Some feedback:

1) Upon closing the GUI, the script doesn't exit. Perhaps add an Esc:: hotkey?
2) Mousedown doesn't seem to work, except when I spamclick the buttons (and then also only temporarily). System info: Win7 x32 Laptop, AHK_L Unicode.

Very nice demonstration! But after quickly looking at the lib code, I have one tip: do not use global functions & variables!

[LiquidGravity]

Thanks!
I agree about globals and it is on my 'to do list' already.

Unfortunately this happened and will take some of my time now. Luckly I uploaded this script just before so I can play a little.

OMG! LiquidGravity I read your post on tic's GDIP thread and I just noticed your examples, they look awesome, why on earth I didn't see them. I'm looking forward to your latest update. Good luck.

This is still very WIP and therefor a lot of the code is messy and lots of it will change every release. Please let me know your thoughts about it.

FYI things I plan to add into the system in the future are:
Text.
Support for more animations (fades, shades, rotation).
Make the lib work without using globals and such. - not as big a priority as getting more features working first.

LiquidGravity You code wizard congratulations! I believe most AHK users was waiting for such a library for a long time. Dragging overlapped transparent controls was unresolved issue of AHK. So your library solved that completely. I am very happy to see this. We can make Packman style games with this, right?. Thank you very much in the name of AHK community.

While dragging image slips away, can it be fixed to stay under mouse from beginning its initial position?

I got an error after adding "few" sprites:

---------------------------
OK   
---------------------------

to obtain a smoother animation, I've set the timer from 70 to 30 ms

SetTimer, Queue_Timer, 30
SetTimer, Mouse_Timer, 30

but that hits the CPU and dragging is not smooth anymore

[CodeEater]

I got an error...

You should post your code.
The problem may be caused by Queue_FileNum variable.

[stevenp]

I didn't changed nothing in the APNG_Demo3.ahk script, just testing: added many sprites by clicking the "This is a Button" Button and the result is the Error Message which was posted above.

[CodeEater]

it works on my computer (tested with ahk_H and AHK basic), except for the mouse-down-image.
