i2sm Screenshot

This is the interface for i2sm. The analysis settings are along the left with the loaded image on the right.

In the image you will notice a blue rectangle. This is the area that i2sm will use when analyzing image data. It is used when creating songs as well as when calculating the dominant and average colors for middle C. You set this rectangle by holding the 'Alt' key and left mouse button while dragging the mouse.

If you look at the image you will see a black circle with a black cross in it. This is the starting point where i2sm will begin its image analysis. You set this point either by clicking the left mouse button on the image or entering the coordinates directly into the StartX and StartY boxes.

If the image where you click the mouse is light like in this image, a black marker will appear. If the image is dark, a white marker will appear.

The analysis rectangle and the starting point are linked. You cannot have a starting point outside the analysis rectangle. So if you try to set the starting point outside the analysis rectangle, i2sm will snap it to the edge of the analysis rectangle. If you try to set the analysis rectangle so that the starting point does not lie within the rectangle, i2sm will snap the starting point to the edge of the analysis rectangle. Its really picky about that.

By default when you load an image, the analysis rectangle is the entire image and the starting point is in the upper left hand corner.

So operation is pretty simple. Load an image, set the settings the way you would like then click Play Midi.
