An indexed image consists of two parts: the indices and the palatte. The palatte keeps track of all possible pixel values of an image, while the indices consists of the palatte index of each pixel.
An indexed image consists of an image matrix and a colormap. A colormap is a c-by-3 matrix of data type double with values in the range [0, 1]. Each row of the colormap specifies the red, green, and blue components of a single color. The pixel values in the image matrix are direct indices into the colormap.
Negative indexing is used in Python to manipulate sequence objects such as lists, arrays, strings, etc. Negative indexing retrieves elements from the end by providing negative numbers as sequence indexes.
In many programming languages (eg: JavaScript, Python, Java, C#, Clojure, etc.) you can use a negative index to select items in arrays or characters in text counting from the end of the array or string. Positive indexes count from the start. Negative indexes count from the end.
It depends on your language, and often on the specific situation. In Python, a negative index means to count backward from the end. So, as long as your negative number doesnt go past the length of the array, its legal. In C, a negative index means to count backward from the start.
If you really need to use negative indexes it is also possible. C / C++ calculates memory address of array element using address of table and then adding index value to it. Using negative numbers just points to memory area placed before your table (which is not you normally want).
Negative indexes refer to the positions of elements within an array-like object such as a list, tuple, or string, counting from the end of the data structure rather than the beginning.
What is Negative Indexing? Negative indexing allows accessing array elements relative to the end of the array rather than the beginning. For example, in Python, index -1 refers to the last element, -2 refers to second last, and so on.
