Re: Convert RGB to HSV
The magic numbers (i.e. the conversion algorithms) are laid out very clearly here: http://en.wikipedia.org/wiki/HSB_color_space which seems to predate Monte Goulding. James Hurley wrote: What I have been using are the following two functions. I believe they originated with Monte Goulding.

Re: Is there a way to suppress https errors?
This is from the more extensive libURL documentation (here http://www.lacscentre.com/liburl/liburldoc.html#libUrlSetSSLVerification): libUrlSetSSLVerification true|false (new in 1.1.1) When set to true (the default), libUrl will use the with verification form of the open secure socket command which uses certificates set in the SSLCertificates property. When set to false, the without verification form is used which enables encrypted data transfer but without being certain who you're sending to or receiving from. Once set, the property is in use for all subsequent requests until it is set differently, so BE CAREFUL with this. (i.e. don't use it unless you know what you're doing) Disabling SSL verification means you don't have SSL working entirely properly. I suspect the truth is that somewhere there is a PEM file that Rev ought to be checking, and when one has a certificate one trusts, one ought to be adding it to the PEM file. The reason that browsers aren't complaining about this certificate is probably because the certificate stores used by them do include a certificate to verify this one.

Re: Load images at proportional size
I need to load at proportional size images inside the image area, but the image area have her own size. How can fit the image inside the image area changing her width and height? If you get the formattedHeight of the image and the formattedWidth of the image, that tells you the original number of pixels. If you pick a fixed height or a fixed width for the display image, you can calculate what the other dimension should be and set the size of the image object accordingly. Make sure you set the lockLoc of the image to true or it will resize to the full dimensions of the image when the stack is opened.

Escaping slashes in Windows for menus?
Up until 3.5 (I think), if you had a popup menu or option menu and you wanted to display a / in it, you had to escape it with a preceding \, but only on Macs. This was (I assume) to differentiate it from a / that preceded an accelerator key. So for example, I have a status popup that lists IN, IN/LW, OUT, OUT/LW, etc., and to make it appear properly on Macs, I had to do IN, IN\/LW, OUT, OUT\LW, etc. but I didn't have to do it on Windows. Now I'm seeing this same need on Windows, but only while running the 3.5 engine... is this intentional (in which case I'll change the underlying code) or a bug? Ken Ray Sons of Thunder Software, Inc.

To swim the math of a pixel grid and pull objects out involves knowing where a region of color is person and where it ain't. That means knowing that a darker part of an arm is still the arm. That means knowing the difference between hue delta and brightness delta. Of course this gets harry when the color of the lighting varies accross an image. But i can parse for and adjust for that. RGB vals don't in them selves carry the data my object parser needs to determine where an arm ends and where it doesnt.

Re: [weblet] How can a webLet communicate with the hosting html page?
Robert, in this first version of the plugin, there will be no direct way for the plugin to talk to the host page but you can script one using sessions. For example, you create a javascript that polls the server at a given interval checking for communication and you make the plugin write to that session when it needs to communicate with its host page. It's a three way communication, like both talking to the server instead of each other but it works wonder for the united nations so far so I think we can keep the traditions.

Re: [revLets] to what extend can the area of a revLet be modified??
Robert, I don't think any plugin can alter it's rect, no matter if it is flash, movie or runrev. I think that what happens in the rect stays in the rect. However, you can make a javascript that picks the screen resolution and write a embed tag based on that information and that tag is used to instantiate the plugin. If you need to resize, you'll need that three way communication that I talked on your previous email and tell the javascript worker to rewirte the embed tag with a new rect. it can be done, needs javascript, XHR, and sessions!

Re: Load images at proportional size
Josep, The crash is indeed a very big problem with DD. It is very frustrating that this hasn't been fixed yet. The following might help. First, get the dragdata and then give Revolution time to deal with it by itself. The send command will execute the remainder of your script after Revolution has done it's thing. local lbl_filename on dragDrop put the last item of the dragdata into fld lbl_filename send doDDstuff to me in 0 millisecs end dragDrop on doDDstuff -- do everything else here end doDDstuff Please, let me know whether this avoids the crash. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering http://economy-x-talk.com Snapper Screen Recorder 2.1 http://snapper.economy-x-talk.com If you sent me an e-mail before 21 June and haven't got a reply yet, please send me a reminder.

Re: Load images at proportional size
Hi Josep, My idea is what I posted a few minutes ago. Apart from that, if you have any repeat loops or wait commands with messages running (or waiting), this might also cause a crash if you drag from the desktop at the same time. If you could avoid running repeat loops and wait command simultaneously with dragging-and-dropping, you might experience less crashes. I suspect that Revolution doesn't respond correctly to a few requests from the Finder, after which the operating system decides that Revolution has crashed, but this is sheer speculation as I don't know any technical details regarding this. -- Best regards, Mark Schonewille Economy-x-Talk Consulting and Software Engineering http://economy-x-talk.com Snapper Screen Recorder 2.1 http://snapper.economy-x-talk.com If you sent me an e-mail before 21 June and haven't got a reply yet, please send me a reminder.

RE: RGB values for a color name
I will look at it. But my work has nothing to do with manual user color management. I am working on deeply semantic pattern logic. I think it is way past time for computers to know enough to try to know. Crazy to have all of this computational power and for it to do no more than it did 20 years ago (just faster). My code needs to know in dreadfully simple and obvious terms what a color of a pixel and how that changes as one moves away from it. This is to imagery what phonems are to spoken language. I really dont care what color a pixel has, just how that is different from other pixels near by. I need as much that i can compare as posible, Knowing the hue and the brightness is a start. I would like to know the minimum noumber of pure colors it would take to make that pixels color... To colors what factoring is to numbers. That would help. Not with the primary colors. Cause that seems realy arbitary (and yes i have heard of newton). Anyway, i am convinced that i can do enough with hue and brightness for a start, what i might have to do is distill just the color component from RGB but keep it in three color values (just without the brightness component). I will work on it and get back to the group. -Original Message- From: paul foraker p...@whitefeather.com To: How to use Revolution use-revolution@lists.runrev.com Sent: 7/5/2009 5:57 PM Subject: re: RGB values for a color name I've put up a one-card stack at http://www.whitefeather.com/tools/colormehexed/ which consolidates some color management stuff I've been working on for the past several months.
