This image has partial transparency (254 possible levels of transparency between fully transparent and fully opaque). It can be transparent against any background despite being anti-aliased. Some image formats, such as PNG and TIFF, also allow partial transparency through an alpha channel, which solves the edge limitation problem.
This is known as transparency, and is seen in many naturally occurring materials (although no naturally occurring material is 100% transparent). Invisibility perception depends on several optical and visual factors. [1] For example, invisibility depends on the eyes of the observer and/or the instruments used.
Transparency can provide almost perfect camouflage for animals able to achieve it. This is easier in dimly-lit or turbid seawater than in good illumination. Many marine animals such as jellyfish are highly transparent. Comparisons of 1. opacity, 2. translucency, and 3. transparency; behind each panel (from top to bottom: grey, red, white) is a ...

Comparisons of 1. opacity, 2. translucency, and 3. transparency; behind each panel is a star. Opacity is the measure of impenetrability to electromagnetic or other kinds of radiation, especially visible light.
A color spectrum image with an alpha channel that falls off to zero at its base, where it is blended with the background color.. In computer graphics, alpha compositing or alpha blending is the process of combining one image with a background to create the appearance of partial or full transparency. [1]
Example of an RGBA image composited over a checkerboard background. alpha is 0% at the top and 100% at the bottom. RGBA stands for red green blue alpha.While it is sometimes described as a color space, it is actually a three-channel RGB color model supplemented with a fourth alpha channel.
The XOR mask conforms to the bit depth specified in the BMP header and specifies the numerical color or palette value for each pixel. Together, the AND mask and XOR mask make for a non-transparent image representing an image with 1-bit transparency; they also allow for inversion of the background.
