I'm trying to load a png image to pdp_reg, but I am getting the following error: WARNING: request to create image packet with illegal dimensions 533 x 400 What are the proper dimensions for using this object? It is not documented anywhere AFAIK.
GEM and PDP have some restrictions on widths of pictures. It has to be a multiple of some number; i think it's 2 or 4 or 8. It may depend on colormodel too, as the point is to prevent unaligned (slow) computations from happening, which depends on the number of bytes per row.
GridFlow accepts any possible size, but it's still best (for speed) to pad or crop the picture to a good multiple: 8 for greyscale and rgb, 4 for greyscale-with-alpha, and 2 for rgb-with-alpha, and so on.
