About Data Types

General

The data type of an image refers to the way that the image is stored internally, how many space (Bits) does a single pixel of the image occupy. This affects the number of colors that an image can display. Images with a data type of 1, 4 or 8 bits contain a palette. Using this technique they do not need to store the color of each pixel, they store only the palette index of the given color. Images with a data type of 24 or 32 bits do not use palettes. They store the color of each pixel separately.

IcoFX supports five data types:

Monochrome (1 Bit)

Each pixel of the image occupies only one bit. You have two available colors in the palette.

16 Colors (4 Bits)

Each pixel of the image occupies 4 bits. You have 16 available colors in the palette.

256 Colors (8 Bits)

Each pixel of the image occupies one byte (8 Bits). You have 256 available colors in the palette.

True Color (24 Bits)

Each pixel of the image occupies 3 Bytes (24 Bits), one byte for the red, one for the green and one for the blue component. You have 16777216 available colors.

True Color + Alpha (32 Bits)

The only difference between the 24 Bits and 32 Bits data type is that the 32 Bits data type stores a transparency value for each pixel. Each pixel of the image occupies 4 Bytes (32 Bits). You have 16777216 available colors plus the opacity information of each pixel.
