Design Statement: The graphic will have its background divided into three sections: the first consisting of the left half, the second from 1/2 to 5/6ths of the width, and the third of the leftmost sixth. The first section will be of a color (henceforth the base color). The middle section will be of a color whose hue is shifted either 30, 45, or 60 degrees relative to the base color (henceforth the primary color). The final section will be be of a color that is of the same hue as the base color, but at a lower value (henceforth the modified base color). These three rectagles, which fill the image, constitute the negative space of the image. The division of only the right half of the image places the weight of the image heavily to the right side. On top of the background will be a set of 0 to 6 radial lines originating from the bottom left corner. The first line will run from the bottom left corner to the top right corner and all subsequent lines will evenly subdivide the angle formed between the first line and the bottom edge of the image. These lines will be in the primary color. There will, additionally, be a graph of a function in black. The function will be chosen on the basis of n from: x^2, ln x, 2^x, sqrt x, ln x. The emphasis of the image will be on a shape that is offset from the right by 1/12th of the image width and is 1/6th of the image width wide. This shape will be 1/4 of the image height tall and vertically centered. This shape will be colored in the true complement of the base color (henceforth the accent color). This shape may be an ellipse or a rectangle depending on the value of n. This shape furthers the sense of weight on the right side of the image. It's vertical center falls exactly 5/6ths of the way horizontally across the image, in accordance with the rule of thirds. Technique Statement: The data for the image will be stored in a 5 element vector. The first element of the vector will describe whether the accent shape will be a rectangle or an ellipse, the second the hue angle between the base color and the primary color, the third what function will be graphed, the fourth the number of radial lines, and the fifth the base color. These elements will be chosen relative to the moduli of n with bases 2, 3, 5, 7, and 11, respectively. This guarantees that 2310 unique images can be generated, as these numbers are all coprime. The use of a vector for data storage assures O(1) access to the elements. The color scheme will be calculated from the base color using the HSV model of color representation. The primary color will be at a hue angle of 30 or 45 or 60 degrees from the base color depending on the value of the second element of the image data vector. It's saturation and value will not be changed. The modified base color will be of the same hue and saturation as the base color, but will have its value halved. The accent color will be the true complement (at a hue angle of 180 degrees) from the base color. Its value and saturation will be the same as that of the base color. The background will be produced by selecting (using GIMP tools) the segments described in the design statement and filling them with their respective colors. The accent shape will also be created as such. Their sizes are defined according to the width and height of the image, and are thus scalable. The radial lines will be constructed by first calculating the angle of the first line and the size of the angle subdivisions. The image-draw-line! procedure will then be recursively called, reducing the angle by the subdivision size on each call, until the angle of the line is zero. The graph of the function will be produced through an image-redo! call using a function that transforms pixels on the function to black and preserves those outside of the function. This will be scaled by calculating an accepted error between the row and the function of the column. The accepted error will be proportional to the minimum of the width and height, thus making the graph thicker on larger images without allowing it to overwhelm narrow ones. All elements not previously discussed will have their dimensions defined in terms of the width and height, as applicable, thus ensuring the scalability of the images.
