MOVE New image location: 1: New locations are determined by adding the MOVE data to the location of the parent object. What *parent* object? Shouldn't this read "respective object(s)"? I would also replace the words "this object" with "the respective object(s)" in the corresponding paragraph in section 4.3.4. CLIP Object clipping boundaries because this object sounds like it's only about ONE object when in fact there may be several involved. I also want to point out a naming inconsistency that happens in several places. Sometimes fields of chunks are written "Last object" (i.e. without underscore) and sometimes "right_cb" (i.e. with underscore). Sometimes the same field is referred to in different spellings. I would also abstain from alternating between uppercase and lowercase when using field names in sentences like in "Last_object must not be less than first_object." Either make field names uppercase in the whole document or lowercase everywhere. My personal choice would be lowercase with underscores everywhere. I would also add a clarification to passages like "It is not an error for the CLIP chunk to name an object that has not previously been defined. In such cases, nothing is done to the nonexistent object." I think this needs an explicit statement that in case an object does not exist the CLIP data is NOT to be stored until the object exists. Otherwise someone could interpret this to mean that the above statement is to mean that "nothing is done to the nonexistent object NOW". The same applies to other chunks with a similar statement. Section 4.3.5. SHOW Show images must specify if it is an error or not to use show_mode 6 or 7 when there are several visible images in the range. The described algorithm suggests it is intended this not be treated as an error but it's not explicitly stated as legal.

That is correct. Decoders are not responsible for creating an object buffer merely to store CLIP data that is otherwise not associated with an object. The reason for allowing the behaviour is to enable the clipping of a range of objects, even if there is a gap in the range. >Otherwise >someone could interpret this to mean that the above statement is to mean >that "nothing is done to the nonexistent object NOW".

The described algorithm suggests >it is intended this not be treated as an error but it's not explicitly >stated as legal. Yes, it is legal. The spec strongly implies that by mentioning "the first visible object that it finds" rather than "the one visible object in the range".

A very enthousiastic Jason Summers has managed to build a MNG-plugin based on libmng, and I can tell you that even I am pretty pleased to see MNG's running on Netscape4.7, Opera3.6 and IE5 on my Win-machine. Now, it's a little too soon to get too optimistic, but things are looking brighter than ever for MNG. You can have a look at Jason's MNG plugin homepage at: http://pobox.com/~jason1/imaging/mngplg/ NOTE that it is v0.1.0 based on libmng0.5.0, so there's still quite some ground to cover. There's also no guarantee that the plugin will work with all versions of browsers in all configurations. And it's only for Win32 for the moment. But hey, it's still magic! Excellent job, Jason!

SourceForge is a free service to Open Source developers offering easy access to the best in CVS, mailing lists, bug tracking, message boards/forums, task management, site hosting, permanent file archival, full backups, and total web-based administration. In the libmng-community I created, I've setup the 0.5.0 downloads, a bug-report section and a developers mailing-list. The download-area now also functions directly as a mirror for the downloads at libmng.com. The homepage for libmng will remain as it is. Both the sites will interlink somewhat, and I'll keep them both up-to-date. The community at SourceForge is mainly targeted at developers and contributing authors. Please feel free to join the group. SourceForge offers many interesting features, such as tracking version-changes, bugs, etc, etc. As soon as I've found time to figure out how to use the CVS system and if people are interested, I'll set this up as well. libmng community: https://sourceforge.net/project/?group_id=5635 libmng homepage: http://www.libmng.com With regards, Gerard. -- Send the message body "help" to mng-list-request@ccrc.wustl.edu From owner-mng-list@ccrc.wustl.edu Tue May 16 11:28:17 2000 Received: from ccrc.wustl.edu (cashew.ccrc.wustl.edu [128.252.169.100]) by swrinde.nde.swri.edu (8.9.3/8.9.3) with ESMTP id LAA23214; Tue, 16 May 2000 11:28:16 -0500 (CDT) Received: (from majordom@localhost) by ccrc.wustl.edu (8.9.3+Sun/8.9.1) id LAA02911 for mng-list-out-eY3f3Qzu; Tue, 16 May 2000 11:27:25 -0500 (CDT) X-Authentication-Warning: cashew.ccrc.wustl.edu: majordom set sender to owner-mng-list@ccrc.wustl.edu using -f Received: from smtp7.xs4all.nl (smtp7.xs4all.nl [194.109.127.50]) by ccrc.wustl.edu (8.9.3+Sun/8.9.1) with ESMTP id LAA02889 for ; Tue, 16 May 2000 11:27:24 -0500 (CDT) Received: from gerard32 ([195.38.202.49]) by smtp7.xs4all.nl (8.9.3/8.9.3) with ESMTP id SAA16874; Tue, 16 May 2000 18:24:32 +0200 (CEST) Message-Id: <200005161624.SAA16874@smtp7.xs4all.nl> From: "Gerard Juyn" To: "libmng News" Date: Tue, 16 May 2000 18:17:37 +0100 MIME-Version: 1.0 Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: 7BIT Subject: Latest news X-mailer: Pegasus Mail for Win32 (v3.12b) Sender: owner-mng-list@ccrc.wustl.edu Precedence: bulk Reply-To: MNG List Hi, It's all going pretty fast. Faster than I expected, so here's another update on the status of libmng. v0.5.1 is out! Yes. Faster than the 1 month-period I've been advertising, but this is a bit of a milestone. It covers all the chunk access functions, including creation and writing. I added two samples that show how to create&examine a MNG, and how to create&write a MNG. There's plenty more things that've changed. For one, this version isn't compatible with the previous. Ouch! Yeah, I've been bad, but some clever guy noted that the callbacks couldn't report their own errors, so that's the change. Most of the callbacks now have to return MNG_FALSE upon failure and MNG_TRUE upon success. Others already had a return-parameter so they remain as they were. Those parameter would already indicate failure in some way. I consider this a milestone in the development as it's more stable than some beta-programs I've tested... I would also really, really, appreciate some feedback from the *nix world. Come on guys, you're always up front; what's going on? ----- I've added a few items to the SourceForge community. There's a task- list now, which shows my dedication to get this thing to a final stage somewhere around the end of June! How's that for tight planning...

Gerard: Because the current code in CVS is v0.5.1, I've tagged it as "v0_5_1" so people can go back to that point in future. How shall we run this? I can just commit every new release as you make it, or we can get you set up with wincvs on your dev machine and have inter-release versions in CVS.
