File Type Options - PBM

The File Type Options dialog is entered when you press Options in the Image Conversion dialog or the Send Image dialog. The dialog allows you to specify convert options for the currently selected image file format.

The available options depend on the file format. Here are shown the options for the Portable Bitmap file format.

PBM files are always saved as Portable Pixel Map (PPM).

Color Mode

Best Fit

Let EasyCopy determine the best color mode. This is the default. EasyCopy will choose the optimal color mode for the given image taking other current settings into account.

RGB

RGB means a 24-bit RGB image ("true color").

Gray Scale

A gray scale image using 8 bits per pixel.

Bilevel

Bilevel means a bilevel, black-and-white image.

Error Diffusion
Enable this option if you want color differences distributed to the neighboring pixels (only available if you select Bilevel). Normally, this results in a substantially better color rendering, although at the expense of image details; the sharpness becomes slightly degraded. Refer also to the topic Image Shading.
