Program Settings

Background Color sets the color of the program's preview window.
Use this option if you want to see your image on the background of some color. This may be helpful for working with a semi- or partly transparent image.

The option does not affect your image.

Zoom Using Mouse Wheel:

• If enabled, the mouse wheel zooms the picture in and out.
• If disabled, the mouse wheel scrolls the picture up and down.

Rotate Image Clockwise sets the rotation direction for the Rotate toolbar button.

Request Saving Confirmation, if set, the program asks for confirmation before saving the modified image. Set this option to protect your graphic file from accidental rewriting.

OpenGL Acceleration, if enabled, lets render the image preview faster while adjusting effect's parameters. Acceleration depends on how your hardware supports it. If OpenGL is not supported on your computer, disable the option.
