Techniques and computing devices related to modifying images are provided. A computing device can receive an order to modify pixels of an image. The computing device can include at least a pixel processor and software snippets that are executable on the pixel processor. The computing device can determine parameter values based on the order. The computing device can select a set of software snippets from the software snippets based on the parameter values. The computing device can load the set of software snippets onto the pixel processor. The pixel processor can execute the loaded set of software snippets to modify the pixels. The computing device can generate an output that includes a depiction of the image that includes at least one of the modified pixels.
