I'm probably doing something wrong here, but I'm new to AHK. I'm trying to use Gdip.ahk and the ConvertImage or convert_resize scripts I've found on here to resize an image. However, when I include gdip.ahk I get an error message.
Code:
Error at line 383 in #include file
"…gdip.ahk".
Line Text: CreateDIBSection(w, h, hdc="", bpp=32, ByRef ppvBits=0)
Error: Duplicate function definition.
The program will exit.
I'm also using a file I got from here, I named the file ScreenCapture,ahk, I don't remember if that was the original name or not. I put a copy below. I'm guessing it is something in this file that is causing the issue, but I'm not sure.
Code:
/* CaptureScreen(aRect, bCursor, sFileTo, nQuality)
1) If the optional parameter bCursor is True, captures the cursor too.
2) If the optional parameter sFileTo is 0, set the image to Clipboard.
If it is omitted or "", saves to screen.bmp in the script folder,
otherwise to sFileTo which can be BMP/JPG/PNG/GIF/TIF.
3) The optional parameter nQuality is applicable only when sFileTo is JPG. Set it to the desired quality level of the resulting JPG, an integer between 0 - 100.
4) If aRect is 0/1/2/3, captures the entire desktop/active window/active client area/active monitor.
5) aRect can be comma delimited sequence of coordinates, e.g., "Left, Top, Right, Bottom" or "Left, Top, Right, Bottom, Width_Zoomed, Height_Zoomed".
In this case, only that portion of the rectangle will be captured. Additionally, in the latter case, zoomed to the new width/height, Width_Zoomed/Height_Zoomed.
Example:
CaptureScreen(0)
CaptureScreen(1)
CaptureScreen(2)
CaptureScreen(3)
CaptureScreen("100, 100, 200, 200")
CaptureScreen("100, 100, 200, 200, 400, 400") ; Zoomed
*/
/* Convert(sFileFr, sFileTo, nQuality)
Convert("C:\image.bmp", "C:\image.jpg")
Convert("C:\image.bmp", "C:\image.jpg", 95)
Convert(0, "C:\clip.png") ; Save the bitmap in the clipboard to sFileTo if sFileFr is "" or 0.

Thanks for the help. If a resize parameter or function could be added to the CaptureScreen function that would work too. I'm fairly certain the ability is there, but it is a bit over my head at the moment.
