I'm seeing the same behavior here, tested with your examples and with the color-temperature operation. If there is no bug filed for this issue, please file one. > By the way, what is the most convenient way for having the input file from > the standard input rather than setting its path in the XML file? > There is such an example on http://gegl.org but I couldn't manage to get it > work and I couldn't find what I had to change in my own command lines above > to do it. Using path = "-" on a load operation is meant to work for this purpose. If it does not, that is a regression and is worth a bug report. > Best regards, > > -- > Thomas Baruchel > _______________________________________________ > Gegl-developer mailing list > Gegl-developer@xxxxxxxxxxxxxxxxxxxxxx > https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer > -- Jon Nordby - www.jonnor.com _______________________________________________ Gegl-developer mailing list Gegl-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gegl-developer
