Set pixels per inch using GDI+
Hi,
I have some code which resizes an image so the longest side is a prespecified value. Resizing is done which retains the aspect ratio of the image.
Is there any function of GDI+ which allows me to specify the ppi or dpi of the image? Currently, all of my resized images are set to 96dpi, but I'd also like to be able to set them to 72dpi.
Thanks for any help, and here is some of the core code
$hWnd = _WinAPI_GetDesktopWindow()
$hDC = _WinAPI_GetDC($hWnd)
$hBMP = _WinAPI_Creat
Maybe this could help you (taken from GDIP.au3):
