John, The information to parse PICT1 and PICT2 are, unfortunately, scattered over several sources. PICT1 is covered in a tech note and PICT2 is covered in IM 5. The new 32-Bit opcodes are covered in the docs for 32-Bit QuickDraw, which are in IM 6 and probably are available from…
"This APDA documentation for 32 bit QuickDraw is more comprehensive than what's available in Inside Mac?" Except for Inside Mac Vol. VI, which hasn't been published yet, there is no 32-bit QuickDraw doc in Inside Mac. The QuickDraw doc in Inside Mac Vol. V only describes the original "Color QuickDraw",…
Where did you get this information? In order to interpret PICT and particularly PICT2 on a non-Mac, I'm going to need to know about some of these 'reserved' opcodes like $009A. I'm curious – if PICT handling is done somewhat transparently inside a Mac program, then how are y'all able…

It's the data fork of a PICT, saved by Photoshop, Stuffed, then split on into data and resource. Read action !
Dear Mr. Syndesis Corp, Opcode 0x009a and 0x009b are the new opcodes DirectBits and DirectBitsRgn (respectively) that were added to support 32-Bit direct rgb pixel maps. These are described in the documentation for 32-Bit QuickDraw. I guess it was intended by Apple that these opcodes would be self-terminating (0x000000ff) because…
What you've got there is a 32-bit PICT. OpCode $9A means DirectBitsRect, provided that you have 32-bit QuickDraw running. Otherwise, as you've noted, regular Color QuickDraw sees an unassigned OpCode with a data length of zero followed by an end-of-picture code. This was done intentionally. A pixelType of 16 means…
I really don't have the time right now to do PICT2 detective work with you (sorry); If I get a chance over the weekend I'll look at the hex you sent. maybe someone else will chime in though. Bill S ps Is this a PICT resource, or a data fork…
My pleasure. Bill S Read action !delete Deleted
After the $00FF opEndPic, it's clear the next thing is a pixMap. It describes a pixMap with a packType of 4, and pixelType of 16, neither of which I can explain. After the pixMap, what follows? Read action ! Mac Developers Forum Read Menu Read 1 [NEW] messages 2 Message…

Print Record Magnitudes
Message #41110
Somehow PrintMgr generates the following rectangles after various "magnitudes" are entered into PrStlDialog. I have tried every combination of integer and floating point arithemetic I can think of, but I don't get these integral values. Every formula I have tried has rounding errors greater than one pixel in at least…

You can also use a disk editing tool to change the boot blocks. Norton's Disk Editor lets you view the boot blocks with labels and descriptions of each value's meaning. Stephen Read action !
Maybe I can show you what I see, and how I interpret it. Here's the start of the file I'm decoding. After the PICT2 version $02FF, I see a HeaderOp $0C00, and skip 24 bytes to location $0228. Then there's a Clip $0001, followed by the rgbSize $00A0, and a…
Mystery solved! I hadn't seen an explanation of the header of 512 bytes. Thanks for your help. Read action !

Non-Mac PICT Parsing?
Message #40790
There are two 'PICT's common in the Mac World. (1) A PICT resource is a picture resource, stored in the resource fork of a file. The structure of a PICT resource, and of a resource fork, is available in Inside Mac. (2) A PICT document is a data fork based…

Non-Mac PICT Parsing?
Message #40676
SIT files are compressed with Stuffit, and must be uncompressed before use. Have you unstuffed the files you downloaded before you examined them? Bill S

Non-Mac PICT Parsing?
Message #40631
There are two versions with a $11 in the header. One is $001102FF a new color PICT and one is $1101 the old standard PICT.
