Thank you, Greg Ercolano.
The problem IS 'file not found'. I put the image files in the âdebugâ
directory. But the default VC2005 directory is something different.
Another question is about using libjpeg.lib to save images as .jpg files. I use
D. Zimmerâs code.

Sounds like a 'file not found' or 'permission denied' situation.
Try supplying the absolute path to the images, eg:
Fl_BMP_Image *bmp = new Fl_BMP_Ima
Hello, everybody.
I am using fltk 1.1.7, Microsoft Visual 2005, and Windows Vista Home Basic. I
added the flowing libs:
wsock32.lib comctl32.lib fltk.lib fltkimages.lib fltkjpeg.lib fltkpng.lib
fltkz.lib
I also added the following header files:
#include

I used below code
