I have a series of thousands of vector objects imported from a DXF file, and sized to an artboard of a specific pixel size (10,160 x 10,160). I need to cut the images up into a grid of 1,024 x 768 pixel chunks - I have setup the 140 slice objects required to do this.
I need the exported images to have no antialising/subsampling applied. I have used the Rasterize effect to rasterize these objects without antialising, and they look just the way I need them too in pixel preview.
When I export the whole image using the File > Export dialog (to BMP or JPG or PNG) the resultant file is correct. However, if I use the File > Save Selected Slices dialog AI applies antialiasing to the images, seemingly ignoring the Rasterize effect, and making them unusable for my intended purpose.
Is this a know limitation, or is there a work around somewhere here?
I can't use the Align to Pixel Grid feature because it doesn't help with curves, instead it just insures that straight lines don't land between pixels (as far as I can tell).
I don't want to use multiple artboards, because of the hard limit of 100 (I'm not eager to do this is in multiple steps, but it might be a work around - say by using two matching files, one with 100 boards and a 2nd with 40).
