Image bit-count/color depth, in computer graphics, is the number of bits used to indicate the color of a single pixel in a bitmapped image or video frame buffer. This concept is also known as bits per pixel (bpp), particularly when specified along with the number of bits used. Higher color depth gives a broader range of distinct colors. Color depth is only one aspect of color representation, expressing how finely levels of color can be expressed; the other aspect is how broad a range of colors can be expressed (the gamut).

After brief introduction about image bit-count\color depth here, if you are eager to know precise way to convert PDF file to image file with specific bit-count\color depth with commands on Windows platform, please remain focused on the following paragraphs.

Step2. Run cmd in your computer

This step aims to show you how to open running environment of commands:

Click hotkey Windows + R > input cmd in pop dialog box Run > click ok

In running environment, to make e-PDF to Image Converter process this mission, please refer to following examples to type your commands one by one:

D:\pdf2image_cmd\pdf2img.exe -mono C:\in\a.pdf C:\out\a.png

-mono: generate a monochrome image file;

-gray: generate a grayscale image file;

-dither 0 or 1: enable or disable dithering when reduce the number of bits per pixel to nbit (1, 4 or 8).

To make e-PDF to Image Converter start conversion from PDF file to image file with specific bit-count\color depth, please click enter there, then typed commands can be effective along with processing on e-PDF to Image Converter, and a few seconds, objective image file with specific bit-count\color depth can be produced successfully.
