· When you have an image open in the main window, double
clicking it will open it in full screen mode. Use the
space bar and backspace to move through other images in
the directory. ESC will return you to the main window.
· You can scroll through a large image faster by holding
down the right mouse button and moving the mouse. You
will see a hand image replace the normal cursor. Move
the hand up or down, or side to side to move the image.
Also, the Page Down and Page Up keys will scroll through
an image that is larger than the screen.
· When scanning a black and white image, you'll get better
results by scanning it as color, at a good resolution,
then using IrfanView to convert to grayscale.
· Enlarging an image: for best results, use Resample, then
Sharpen. For an image of decent resolution, this will make
an enlarged version with no loss of quality. If the large
version is not good enough, Reopen the image (without
saving anything.) A fresh copy will be loaded. Try the
resampling again, but use a different filter.
3D Button option. (Image menu, select Effects, then select
3D Button.) If your image is a simple line drawing, or just
a colored rectangle you made into a button, use Negative to
create a reversed-color image. Save this to your disk. Now
a mouse rolls over it.
· Be careful with "multiple instances" of IrfanView. It is
possible to highlight a long list of associated filenames
in a directory, then accidentally double-click them.
In this case, IrfanView will try to load itself as
many times as there are images!
