In another screen, the position is wrong

[sxzxs]

I have double screen, but in another screen, the position may wrong!

Can you show where it is wrong? This was tested using Mutiple monitors with different DPI.

You may find a test script in: https://github.com/iseahound/TextRender/releases/tag/v1.8
Run: Showcase 03 - Speed Test.ahk

[sxzxs]

Using your test program, as shown below, change x to a negative value, and y will stop when it moves to a position
main screen:1920x1080, another:1920x1200

this is a bug? i run same test with v2, same result.

[iseahound]

Yes, this does appear to be a bug. It seems to only happen with the y-axis on multi monitor systems

[iseahound]

And the reason it happens is because of lazy coding :)

I should have used a proper struct.

Fixed by c1c397e.

Thank you for providing detailed instructions on how to reproduce the error, and for being patient.

Please test the v1 and v2 code to ensure it is fixed

I have test with v2 and v1 use new version,it work good!
Thans you very much! I often use TextRender!

I have a quick question, can I know the height or width of the text before rendering?

[iseahound]

I suppose you could do something like this:

#include TextRender.ahk
wh := Width_and_Height("hello world!", "s:42")
MsgBox wh[1] ", " wh[2]

Width_and_Height(text, s1:="", s2:="") {
    static tr := TextRender()
    tr.Draw(text, "x:0 y:0 c:None" . s1, s2) ; only supports string syntax, feel free to check for an object!
    try return [tr.w, tr.h]
    finally tr.Flush() ; Use this to clear the graphics 
}

EDIT: I highly recommend using Draw() before Render(). You can check the width and height between the DrawToScreen action.
