Re-2: rotating images... after exif check

[runrev at animabit.de]

Hello,

I need (lossless) rotation (90) within runrev using an image object with included image data for automatic correcting images with wrong orientation 
after having got the exif information.
As you said
rotate img 1 by -90 
produces a white border within the image. How can I avoid this and really get a fine rotation of the image (within runrev, no externals please).

Any further suggestions appreciated.

Regards,
Mit freundlichen Gren
Franz Bhmisch

The exif step is working now using the getexif library of UDI for getting the exif info out of any jpg:

#####################################################
## getExifData( ) -- return Exif data list
## those handlers are public domain
## 2005.07.24 UDI
## 1.1 -- Windows problem fixed 2006.01.10
## 1.2 -- TIFF support 2006.01.11
## 1.3 -- endian problem fixed 2006.01.12
## 1.4 -- added 2 tags (TIFF width/length) 2006.01.13
## at http://homepage.mac.com/udi/stack/tool.html

you just have to add in the script

case 274 -- 0x0112
put getInt( imgData, dataPos +6, endian ) into aNum
put return & "Orientation:" & aNum & getOrientationMode( aNum ) after theResult
break

function getOrientationMode aNum
switch aNum
case 1 return "(= normal)"
case 6 return "(= hochkant links)"
case 8 return "(= hochkant rechts)"
default return ""
end switch
end getOrientationMode
