# fz_shdr_get_ispace_xy

Description

Gets the 2d image space coordinate of the current pixel. The pixel in the upper left corner of the rendering has the coordinate (0.0, 0.0). The pixel in the upper right corner of the rendering has the coordinate (1.0, 0.0). The pixel in the lower left corner of the rendering has the coordinate (0.0, 1.0). The pixel in the lower right corner of the rendering has the coordinate (1.0, 1.0).
Note, that this function only has a meaningful use when called from a shader's pixel function. When called from any other place, the resulting xy value is undefined.
