Negativno

These are all blending modes which seem to make the image go negative.

Seštevno odštevno

Nasvet

This blending mode is called „Additive Subtractive“ in English.

Subtracts the square root of the lower layer from the upper layer.

Levo: Navadno. Desno: Seštevno odštevno.

Arkus tangens

Nasvet

This blending mode is called „Arcus Tangent“ in English.

Divides the lower layer by the top. Then divides this by Pi. Then uses that in an Arc tangent function, and multiplies it by two.

Levo: Navadno. Desno: Arkus tangents.

Razlika

Nasvet

This blending mode is called „Difference“ in English.

Checks per pixel of which layer the pixel-value is highest/lowest, and then subtracts the lower value from the higher-value.

Levo: Navadno. Desno: Razlika.

Ekvivalenca

Nasvet

This blending mode is called „Equivalence“ in English.

Subtracts the underlying layer from the upper-layer. Then inverts that. Seems to produce the same result as Razlika.

Levo: Navadno. Desno: Ekvivalenca.

Odvzem

Nasvet

This blending mode is called „Exclusion“ in English.

This multiplies the two layers, adds the source, and then subtracts the multiple of two layers twice.

Levo: Navadno. Desno: Odvzem.

Negacija

Nasvet

This blending mode is called „Negation“ in English.

The absolute of the 1.0f value subtracted by the base subtracted by the blend layer. abs(1.0f - Base - Blend)

Levo: Navadno. Desno: Negacija.
