Is it called

Auf dem transformierten Bild


Auf dem transformiertem Bild

and whats the rule for this?

Edit: All found answers are not covering dative.

    The question is about the same grammatical phenomenon (weak vs strong declension of adjectives), but the dative isn't covered.

    The adjective ending on n is correct here. Loosely spoken, there is already an m in dem, so you don't need another. So it is auf dem transformierten Bild, or auf einem transformierten Bild, but auf transformiertem Bild. I don't know the exact grammatical rule, but the only one m "rule" has always worked for me. <g> Commented Aug 12, 2017 at 19:17

The rule is one m and one n, basically. If the article ends with an m, the subject will end with an n. That's how I learnt it, at least. Just so know, most native speakers will not know / do this wrong. ;)

    Auf dem transformierten, roten, scharfen, kleinen Bild - one m, multiple n. Commented Aug 12, 2017 at 22:35

Since there is a definite article, the weak declension is used for the adjective, so transformierten (dative) is correct.

Since it's das Bild, the gender is neuter. Here's the forms for all cases:

|Case|Singular             |Plural              |
|Nom |das transformierte   |die transformierten |
|Gen |des transformierten  |der transformierten |
|Dat |dem transformierten  |den transformierten |
|Akk |das transformierte   |die transformierten |

Without an article, the strong declension is used:

|Case|Singular         |Plural          |
|Nom |transformiertes  |transformierte  |
|Gen |transformierten  |transformierter |
|Dat |transformiertem  |transformierten |
|Akk |transformiertes  |transformierte  |

So if the "dem" were missing, transformiertem would be correct.
