Hi, I suppose that the graphics package will be written from scratch for LaTeX~3 in order to make use of the new syntax. This might be a good opportunity to add a new feature. Admittedly, I never used the viewport option of includegraphics in the past because I only included vector graphics, where it doesn't make much sense. However, when I prepared the TUG-2015 photos for the next TUGboat release I encountered an inconvenience. The viewport is specified in terms of pixels. After downsampling the photos I had to change the viewport arguments (divide them by the downsampling factor). This had to be done manually and thus was quite inconvenient. It would be quite handy to have an option which behaves similar to viewport but accepts arguments relative to the size of the original graphic, for instance [0.15 0.2 0.87 0.98]. Maybe it's also possible to add another option which displays a grid. Such a grid can be very helpful in order to determine the desired values. I'm convinced that relative coordinates are even more comprehensible to users because it's not necessary to know the actual size of an included graphic. Since we have pdftex now, which supports PDF, PNG, and JPEG, it's more difficult to determine the size of a graphic. And the log file isn't helpful because values are in pt while the viewport option expects them in bp. | <foto/ltx/dpc.jpg, id=44, 1027.84pt x 832.10875pt> | File: foto/ltx/dpc.jpg Graphic file (type jpg) | | <use foto/ltx/dpc.jpg> | Package pdftex.def Info: foto/ltx/dpc.jpg used on input line 118. | (pdftex.def) Requested size: 178.5416pt x 144.54pt.
