Image tool using Nconvert activeX Control

[nobbe]

i found nconvert to be alot better in conversion of files than cximage so i changed the sample code to work with

GFLAx (ActiveX/ASP component) v2.70, which is free for private use

Its a Free grafik Manipulation Library supporting a large number of file Formats

please check the developers page for more information

New 13.06

- i added some object checking

- color codes are now directly used from RGB

;
; all api functions can be taken from the help CHM file, which is extensive
;

;
; to register the active X control do this :
;  copy GflAx.dll c:\winnt\system32
;  regsvr32.exe GflAx.dll
