Hello,
I have several pictures and they are of different sizes, Is ther a
procedure to display the pictures so they appear to be the same size or
convert them to the same size?
Thanks for any suggestions.

There is a C function called StretchBlt... look for references to it
in the archives, my memory isn't want it used to be.

Thanks to you and Patrick Barnes for your help. I could get your test to
run ok with my pictures. I have moved your test.ex code to a windows
program and tried to run. I have trouble with the Init instruction. It
checks the first statement and aborts. I mcopied the CXimage .ex and the
Cximage.dll to the folder wher my program resides. I then moved them to
the include folder in Euphoria folder and I still bomb off on the
initialization statement. I haven't used the dll files too much so I'm
not sure. Could it be windows on XP ?
Anymore help would be appreciated
Thanks to all
