Lines Matching defs:zoomed
44 * \param x0, x1 returned X bounds of zoomed region [x0, x1)
45 * \param y0, y1 returned Y bounds of zoomed region [y0, y1)
46 * \return GL_TRUE if any zoomed pixels visible, GL_FALSE if totally clipped
103 * Convert a zoomed x image coordinate back to an unzoomed x coord.
104 * 'zx' is screen position of a pixel in the zoomed image, who's left edge
