Options for TIFF

 

 

Here you can adjust the settings of TIFF image files, see the details for each below:

 

Color Depth

You can change the color depth of the image by selecting the number of bits per pixel (bpp):

oBlack/White (The black-and-white (bi-level) image means that for each pixel (picture element) in the image, we do not need three bytes as in the true color image (over 16.7 million colors), but only one bit that is 1/24 part of the pixel size from the true color image. The one-bit pixel can express only black or white colors, nothing more.)

o4 bpp

o8 bpp

o24 bpp

o32 bpp

 

Note: TIFF in the Windows GDI library does not work with 16 bpp. Color depths set lower than 16 bpp will result in some losses in image quality.

 

Compression

You can compress TIFF files to optimize space; LZW and Packbits are used for all colors; CCITT Group 3 and 4 are only available for black-and-white.

oLZW — You can compress any TIFF image of any bit depth using LZW, a lossless compression method. The application can store the compressed image in a TIFF file or keep it in memory. An average 2:1 compression ratio is achieved with LZW compression on images.

oPackbits — You can compress and decompress grayscale, palette, and bitonal images using Packbits—another lossless compression method. Packbits are fast, widely supported, and provide good compression of sparse images, such as scanned documents. The application can store the compressed image in a TIFF file or keep it in memory.

 

Photometric Interpretation

For the black-and-white and grayscale images, when "Black/White" or "4 bpp" options are selected as color depth, you can specify the intended interpretation of the image pixel data. Select one of the following options:

oWhite is Zero — The minimum sample value is displayed as white.

oBlack is Zero — Default value; the minimum sample value is displayed as black.

 

Image Resolution

You can change the horizontal and vertical resolution of images from 96 to 300 dpi (dots per inch). The default resolution is 200 dpi. The same rule applies here: the larger the resolution, the more computing time and power are consumed and, therefore, the larger the image file sizes.

oVertical Resolution = Horizontal Resolution — If this box is checked, the horizontal and vertical resolutions will have the same dpi.

 

Note: Choosing a higher resolution will slow down processing significantly and affect the final quality.

 

If you want the selected values as default, you may click "Set default values" to keep the settings the same for all images created in the future.

 

Options for PDF

 

 

oUse Content Compression — Checking this option results in considerably smaller files. You can choose to compress the content, thereby reducing the file size by roughly 50%.
