It Screenshots

Mon Apr 20 14:15:09 1998

Used some time this weekend to add rectangles and ellipses.

1. Image 1 shows the new tools in the ToolkIt.
2. Creating a rectangle.
3. The same, but with SHIFT pressed, the object created will have identical sides (the rectangle will be a square; the ellipse a circle).
4. Resizing a rectangle.
5. With CONTROL pressed, resizing is done from the center of the object. CONTROL will also work during creation (SHIFT during resize has not yet been implemented).

Ellipses function fully analoguous to rectangles, but I don't dare to show them yet, since they do not look like ellipses yet :-) (The assumption that ax == ay == 0 in the curves is wrong.)

Another evening session (the eleventh working-day equivalent, I think). Done some details in TAG again (added Panel; implemented the main/key window abstraction), and implemented the groundwork for the inspector panel. Right now, the active document shows nice `empty selection' and `multiple selection' inspectors for the obvious occasions, and there is a default inspector for objects, which is shown below.
One notable addition today is that Illustrate It! has had the first revision of its file format. Since the file format mostly is a (human readable) object archive, this revision is nothing more than an archiving version bump of a single class (the `closed' attribute of a Shape path, if you really want to know). However, It! has been shown to correctly write the new version (duh!), and correctly read both the old and the new version, so the machinery underlying the support of an evolving file format has been shown to work. I intend to maintain this level of format support throughout It! development: at any time you can use It! for something real, and be certain that future versions will be able to read your files. (It's an intention, not a promise. Fingers crossed; no warranty.)

Full session last night. Fixed the object selection behaviour and added incremental selection: click with SHIFT pressed toggles the selected state of the object or point. Another, most visible, change: modifying a curve by dragging control points has been implemented. The images below show:

1. A path with three points (and two curve segments).
2. The rightmost control point is being dragged, thereby modifying the two control points of the selected point. Both the original path and the path resulting from the modification are shown.
3. After releasing the mouse, the path has been modified. Fully un-/re-doable, of course.

Found a few hours to work on It! again. No screenshot-able changes though:

• Files can be saved and loaded. Specify them on the command line to load them (or to name a new file), and click the File/Save menu item to save. The save format is textual and readable, though not very pleasing to the eye.
• Exporting a file foo.it creates a file foo.eps.
• Starting It! without any file arguments creates a new document untitled-xxx.it, where xxx is some number to make the filename unique.

Numerous changes and additions in a short session:

• The path tool can create bezier curves. Image (1) shows three such curves; the circle-like curve is selected; two of its points are selected; the other two are not. Selected points can be dragged; control points can't just yet.
• Image (2) shows what ghostview thinks of the EPS file created by exporting the document shown in image (1). The resemblance is stunning :-)
• EPS exporting writes to the file it-out.eps in the current directory instead of to stderr.
• Lots of fixes, great and small.

New tool: the path tool (image 1), to be used to create paths (with exactly one sub-path). Currently, it can create a path with the first point, and the user interface of adding another point is functional (in image 2, with the mouse down at the selected point; the mouse is busy dragging the lower right of the three (cross-shaped) control points).
