I have use for an absolute zoom. The goal would be to make the width of the viewport equal to a specified number of Angstroms at the center of the molecule. I would like to make a group of atoms of known size fit a specified portion of the viewport, regardless of the size of the molecule containing those atoms. For example, what if I wish to zoom a clump of amino acids 20 Angstroms across such that it fits 2/3 of the width of the viewport? Is there any way to do this?
By "absolute zoom", I do NOT mean a percent zoom value. As I understand it, the percent is relative to the arbitrary default initial zoom level set to fit the entire molecule in the viewport. With relative zoom percentages, I have no idea what the width of the viewport is in Angstroms (at the center of the molecule). "Absolute" refers to the ratio of Angstroms to the size of the viewport. To fit 20 Angstroms into 2/3 of the viewport might occur at 100% for a small molecule, and at 1,000% for a large one. For example zoomTo 1 a30 could mean zoom in 1 second to "a" Absolute zoom, "30" meaning that the viewport is 30 Angstroms across. When the viewport is rectangular, I don't care whether the specified Angstroms refer to the horizontal or vertical size, or to the average of those, provided the mechanism is clearly stated.
