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.

Step1. Download e-PDF to Image Converter

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

 

Step3. Input commands and start conversion from PDF file to image file with specific bit-count\color depth

 

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

D:\pdf2image_cmd\pdf2img.exe –dither 1 –mono C:\in\c.pdf C:\out\c.tif

D:\pdf2image_cmd\pdf2img.exe –dither 0 –mono F:\source\d.pdf D:\target\d.jpg

where you need to know:

….exe is path of “pdf2img.exe” typed for running e-PDF to Image Converter;

….pdf is source PDF directory typed to add PDF itself for conversion;

….png, bmp, tif, jpg are paths of targeting image file typed for saving image files themselves;

-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.
