How to get image dimension of floating point and 32bit images? [SOLVED]

Recommended Posts


Hi everyone,

How to get the image dimension of 32 bits and floating point images?

this returns weird values , like 4294967295 for the width and 0 for height :

#Include <GDIPlus.au3>

$theFile = "C:\Image.tga"

$hImage = _GDIPlus_ImageLoadFromFile ( $theFile )
$iWidth = _GDIPlus_ImageGetWidth ( $hImage )
$iHeight = _GDIPlus_ImageGetHeight ( $hImage )
_GDIPlus_ImageDispose ( $hImage )

ConsoleWrite ( "Image Dimensions = " & $iWidth " * " & $iHeight & @CRLF )

Same issue with Targa (.tga) images 32bits.

Open EXR Sample images : Sample Images for download


Just wanted to add that this doesn't work either :


Solved using freeimage.

Exr image format is not supported by GDI+ and that's the reason why you get strange values.

$hImage = _GDIPlus_ImageLoadFromFile ( $theFile )
If @error Then Exit MsgBox(16, "ERROR", "File couldn't be loaded")

should help to see whether image format is supported or not.



Please don't send me any personal message and ask for support! I will not reply!

Yes, I tried already, and _GDIPlus_ImageGetType returns -1 on EXR files. I think -1 is $GDIP_IMAGETYPE_UNKNOWN

But I am still open for other alternatives to freeImage, because I find it a bit slow compared to the speed of GDIPlus on jpg images.
