I find that the current Macintosh graphics handling is often quite lousy. Let me illustrate that with two examples: - When you copy graphics from MacDrawII to Word 4.0 or WriteNow 2.0, linestyles (dotted, striped) and line thicknesses usually get mixed up. When you resize the MacDraw graphic in Word, e.g. a flowchart, things misalign, causing the text and the boxes around it to overlap. - We use IGOR, a sophisticated "plotting" application that I can heartily recommend. Suppose you plot a smooth function like a sine. Directly printing from IGOR to the LaserWriter gives perfect smooth results. However, exporting the graph to Word or MacDraw and printing no longer gives a smooth result. Doing so, the function looks "piecewise continuous". So when making publications, we still end up with cutting and pasting, using real scissors and glue. A Mac programmer omce told me that these problems are due to the limitations of Quickdraw, which is used when copying something to the clipboard. I would like to know if these problems are going to be addressed in new system software. I think they should, because presently, two "standard tools" like Word and MacDraw can't communicate properly with each other.

What Word gets is a bitmapped image of your object from IGOR... then your printer does a 72 dpi job on an otherwise beautiful graph.... just a thought.. maybe well off into the ozone.. -kevin ramsiri@blake.acs.washington.edu

I've also run into this problem with MacDraw II and Word; it's a real pain. <chaz> -- ---------------------------------------------------------------------- Chaz Larson - clarson@ux.acs.umn.edu "Hey, I'm no Jack Kennedy..." - Flaming Carrot ----------------------------------------------------------------------

The one big ugly with PICT is that it has a resolution of 72 DPI. This means that all distances will be rounded to the nearest 1/72"; so fine detail may be (and frequently is) lost. Chaz is correct about graphics being stored in the clipboard as PICT, but it's the application that the graphic came from that does the <internal format>-to-PICT translation. So while PICT is capable of representing objects, line styles, &c., the application is under no obligation to do it that way. It could, for instance, turn the whole picture into a bitmap and give that to the clipboard. (Never heard of anyone actually doing that, though :) Note that most apps only turn stuff into PICT when they're going to paste into another application; otherwise they use a special internal clipboard to make sure no information is lost. So there are two things that could mess up your picture when copying and pasting it between applications: one is the 72 DPI nature of PICT itself, the other is applications not supporting all of PICT's capabilities. There has been talk for some time (mostly in the CAD area) of making a "high-resolution PICT" standard, but nothing (to my knowledge) has ever materialized. Chris Nebel nebel@wam.umd.edu

From: J.Pearce@uk.ac.ucl.cs We too have suffered from problems when transferring simple pictures from MacDraw II 1.1v1 to MS Word and a variety of other applications. We have had particular problems with arcs joined to straight lines that look OK in MacDraw even if you zoom in 3200%, but as soon as you copy them to the clipboard there is an erratic alignment problem (if you use show clipboard in MacDraw the problem is visible). The only work-around we have found is to save the picture in PICT format, re-open the PICT file, then copy. This is tiresome, but it seems to aleviate the problem. To have to resort to manual cut & paste on a macintosh is a "crime". System 7 must be an ideal opportunity to address this problem. John R.
