MACDRAW REPLACEMENT CODE

The numbers in the left halves are the hex representation of the code and to the right is the ASCII representation.

The breaks in the sector views are where they become all zero from then on. 2 в€џedit+В’ View of the В“MacDrawВ”ed Polygon FileДЇigure 2 is the В“ Fedit+ В”ed look at both sectors of the MacDraw В‘PICTВ’ file called В“PolygonВ”. Now letВ’s view what you find in Fedit+ and take a close look at the header.ДЇig. A quick mental calculation tells us the header is our old friend, 512-bytes, long! Same length as the В‘PaintВ’ file headers were. ThatВ’s good, since the actual В‘PICTВ’ure part of it is only 58 bytes long. The total file size, as stored by MacDraw, is just 570 bytes. Figure 1 shows the polygon as you normally see it in MacDraw.ДЄs we can see, thereВ’s not much to it. I went into MacDraw, itself, drew a simple five-sided В‘closedВ’ polygon, saved it as a В‘PICTВ’ file and then went into Fedit+В™ to take a look at it with tech note #27 in hand. Rather than just drone on and on, itВ’s time for an example. The PICT format is the one weВ’ll look at in MacDraw. The DRWG format is the internal one that only MacDraw understands. Referring you to tech note #21, MacDraw gives you the option to use two file formats. thatВ’s what makes a picture record into a В‘PICTВ’ file. So, whatВ’s missing? Well, itВ’s a header of some kind. If we were to write out this picture record to a file weВ’d have what we need, right? Wrong! All of the programs mentioned previously would spit-up something terrible. It is important to point out that the size (picSize) includes the first two fixed-length fields themselves. Immediately following the two fixed-length fields are the В‘QuickDrawВ’ calls to generate the picture. The record always starts with the following two fixed-length fields: Since pictures are all of varying size, i.e., length, as we could have guessed a Picture is really just a variable length record. The things that get stored in the files and also sent to the LaserWriter are those calls friends, not a bit image! Whoa ! ! ! What happened to all this elements, objects, and vector stuff this idiot was just talking about? Well, the bit image theyВ’re talking about on page 158 is the screen.

And, as you will see, В“drawВ”ing a В‘PICTВ’ file in ZBasic is even easier than В“paintВ”ing a В‘PNTGВ’ file in ZBasic as I covered in a previous article.ДЇirst of all, there are several good references on the В‘PICTВ’ file format and В‘QuickDrawВ’ing a picture, so IВ’ll give them to you now. It is В“ В‘PICTВ’ing В“ that weВ’ll be covering in detail. Getting into those formats is not the purpose of this article. The В‘PICTВ’ format is also inherently faster than most because it is the format that В‘QuickDrawВ’ in the ROM is using to begin with!ДЄll of the graphics programs mentioned previously also have their own proprietary file format, including MacDraw. This even holds true for text! As the quest for higher and higher quality proliferates, the В‘PICTВ’ format will become even more prevalent. ThatВ’s why a diagonal line has nice sharp edges, and not the В“jaggiesВ” that go with the individual pixels of a bit map. The LaserWriter with its PostScriptВ™ language treats all В‘PICTВ’ elements as separate objects, not bit maps, and prints (or better yet, В“drawsВ”) them vectorially. Why all of this compatibility? The answer to that one is simply called the В“LaserWriterВ™В”! In addition to all of the above a word processor like WordВ™ 3.0 will pass В‘PICTВ’ information back and forth through the clipboard and retain the individuality of each В‘PICTВ’ element. However, layout programs like PageMakerВ™ will also read В‘PICTВ’ files in directly with its В“PlaceВ” command. To name just a few, MacDrawВ™, MacDraftВ™, Cricket DrawВ™, and SuperPaintВ™ all will both read and write В‘PICTВ’ files. The В‘PICTВ’ file format is rapidly becoming the standard for transferring High Quality graphics between programs, and not just graphics programs. This article should really have been titled В“ В‘PICTВ’ing in ZBasicВ™ В“, but that didnВ’t sound quite as clear.
