Get Image width and Height of files of the formats PNG,JPG,TIF
Jayadev U
Hi,
Is there a way in Harbour to get the width and height of an Image in Pixels (Image can be in any format)? I tried with freeimage as posted in \Hb34\contrib\hbfimage\tests but I get the error “The application was unable to start correctly (0xc000007b)”.
Warm regards,
Jayadev

you can use "Bos Taurus" LIB
nHandle := BT_BitmapLoadFile( cPath + cLoad )
nWidth := BT_BitmapWidth( nHandle )
nHeight := BT_BitmapHeight( nHandle )

Hi Jimmy,
Thanks for your immediate reply. I had already tried the excellent BosTaurus library. However the following functions are not defined in console mode and hence I am unable to use the lib.
Errors:
hbmk2: Error: Referenced, missing, but unrecognized Harbour function(s):
GETFORMHANDLE(), RELEASEALLWINDOWS(), GETWINDOWLONG(),
GETCONTROLINDEX(), GETCONTROLTYPE(), GETCONTROLHANDLE()
Warm regards,
Jayadev

The best way is Freeimage, but I too wasn't able to make it work with recent distributions, but it worked in an old one. The other way could be Imgmagick via a shell command, creating a txt file with the output of the command identify.
I do it in Linux and it works.
The last possibility would be to fopen the image and try to read directly the infos in it, but it proved to be quite complicated.
For PDFs IIRC I used Ghostscript, via shell command as per
Imagemagick.
