Re: Keeping a field scroll at the bottom as lines come in

I usually just pick an arbitrarily large number and set the scroll to 
that. 99 works for most purposes.

Question about icons

[Doug Lerner]

Is there an easy way to use the icons in the Rev standard toolbar in my
stacks. Is that acceptable practice?

I notice, for example, that the id of the "line" icon is 200020. But it
doesn't show up in the icon library. Do I need to import it or something?

Thanks,

technical question about Rev's base64decode

[Doug Lerner]

When base64encode is used, Rev wraps at 72 character lines.

I notice if you remove these lines and base64decode you get back the same
original results. In other words, the linefeeds are ignored.

Looking at the RFC for base 64 encoding, they say that lines should not be
more than 76 characters but that "robust applications" may support longer
lines.

Does Rev, in general, support any sized strings for base 64 decoding?

Thanks,

Re: image transfer not working again...

[Doug Lerner]

And now it is working again.

What I am doing is NOT sending "the imageData" and instead sending the raw
image instead. On the receiving side I am:

1. Setting what templateImage parameters I can, such as "location".

2. Setting the global paintCompression property.

3. Creating the image.

4. Finally using "put into" to change the raw contents.

That seems to work. For now. Is that what everybody else does when they need
to do something like this?

image transfer not working again...

[Doug Lerner]

I got it to work at least once last night, and now I am getting scrambled
images again.

A couple of questions, the answer to which might clear up my problem:

1. I think my problem is that I am sending "the imageData of image myImage",
which is the 4-byte-per-pixel visible format of the raw data. The raw data
is actually just "image myImage". Is that correct? Should I be sending the
raw data instead?

2. Before creating the new image from the received data, I want to set the
appropriate templateImage properties. But what is the property containing
the raw image? It appears to be "the value" of the image, but that doesn't
seem to be settable directly. I am left with using "put into" after the
image is created?

Any advice would be great.

Re: What is Rev doing?

[Jerry Daniels]

Friends,

I believe revScriptEdit is a message that is sent by the Rev IDE so 
that the IDE can check to see if you have depressed certain modifier 
keys that will, in turn, bring up a script editor or a property 
inspector. This involves cpu usage.

Is this necessary? Yes and No. This would be TOTALLY unnecessary if the 
Mac could tell if one or more modifier keys are down via rawKeyDown, 
but it cannot and therefore the revScriptEdit message is sent for all 
platforms.

I could be wrong, but that's what my look into this issue tells me.

Re: geometry-challenged

[Brian Yennie]

For the problem at hand, it should suffice to add a little if-logic to 
the beginning.

A line between two non-overlapping objects will always intersect 
exactly one of the sides of each object- you just have to pick the 
right one and _then_ use the intersection function.

With that said, an intersection function should probably error 
gracefully for parallel lines (i.e. non-intersecting).

- Brian

   I tried the function on two *non*-intersecting lines, and it gave 
me a "divide by zero" error. Not good. You need to find the 
mathematical intersection of the infinite lines defined by the two 
pairs of endpoints, and *then* decide whether or not that intersection 
point is within *both* of the line *segments* defined by said points.

However the solution to fix the stack was not successful although the

Re: Keeping a field scroll at the bottom as lines come in

[Dan Friedman]

Rob,

Let me also welcome you to Revolution!  When I add text to list fields, I
usually want to hilite the new line of text.  So, here's what I do:


on addALineOfText someText, fieldName
   put the number of lines in field fieldName into nLine
   put someText into line nLine+1 of field fieldName
   set the hilitedLines of field fieldName to nLine+1
end addALineOfText


Setting the hilitedLines of a list field will automatically scroll the field
to that line.

Hope that helps...

-Dan

put  after field "myField"
set the scroll of field "myField" to the formattedHeight of field "myField"
It's not a very elegant solution, but as the formattedHeight will be 
always larger than the maximum scroll value,  it'll do the job.

Hi Rob,

Welcome to the Revolution :-)

Your question is not naive, and the solution is not
too hard either ; here's what I usually use to make a
field scroll to the bottom while appending :
--
  put return & "Yet another line" after field "Foobar"
  set the scroll of field "Foobar" to \
  the formattedHeight of field "Foobar"
--

Hope this helped,

Jan Schenkel.

Richard,

I'm not sure if this helps, but the function "intersection" below 
will return the intersection of any two lines. The first line is 
defined by its end points p1 and p2; the second line is defined by 
its two endpoints pp1, and pp1 (not the best notation.)

It is part of my Turtle Geometry tools. (Shameless plug: 
Indispensable tools for doing heavy graphics. From what I understand 
from Ro at the Developers' conference, Turtle Graphics may be 
incorporated in future editions of RR. This intersection function is 
not a traditional component of TG--so it may be included and it may 
not. In any event, it stands on its own.)

function intersection p1,p2,pp1,pp2
  put item 1 of p1 into x1
  put item 2 of p1 into y1
  put item 1 of p2 into x2
  put item 2 of p2 into y2
  put item 1 of pp1 into xp1
  put item 2 of pp1 into yp1
  put item 1 of pp2 into xp2
  put item 2 of pp2 into yp2
  if x1 = x2 or xp1 = xp2 then
if x1 = x2 then
  return x1&comma&yp2 + (x1-xp2)*(yp2-yp1)/(xp2-xp1)
else
  return xp2&comma& y2 + (xp1-x2)*(y2-y1)/(x2-x1)
end if
  end if
  put yp2 - y2 + x2*(y2-y1)/(x2 - x1) - xp2*(yp2 - yp1)/(xp2 - xp1) 
into numerator
  put ((y2 - y1)/(x2 - x1) -(yp2 - yp1)/(xp2-xp1)) into denom
  put numerator / denom into x
  put y2 + (x-x2) *(y2-y1)/(x2-x1) into y
  return x & comma & y

Re: A bit stuck on creating a new image

[Frank Leahy]

You might consider changing your server protocol to not use CRLF as the 
delimiter (I'm assuming you wrote the server portion too?).  In HTTP 
for example, the web server either sends the image size in the http 
header, or if that's missing, it assumes the image is complete when the 
connection closes.

You might consider having two data types, text and binary, and when you 
send text it's CRLF delimited, and when it's binary, you send along the 
size.

Thanks for the reply.  I thought suspending the IDE would
avoid the problem, too, since the standalone works fine.
However, it was even worse, as I had to force quit Rev.

Re: A bit stuck on creating a new image

[Klaus Major]

Hi Doug,

Whew! It took forever to figure out, but I finally stumbled across the 
right
combination of image compression, base64 encoding and required 
properties
that need to be communicated over the socket and it seems to be 
working.

I was surprised that I was able to get this to work, though, with just 
the
paintCompression and imageData properties, and that that value of the 
image
itself was not required. That seems a bit counter-intuitive.
Have you tried to "compress" (see the index) the imagedata before 
sending?
Instead of base64 encoding...

Might reduce filesize/transfertime...

Just a thought :-)

Re: shutDownRequest being called twice

[Thierry Arbellot]

Good question. I never asked myself about it before, I just used local 
variable to share and retain value within handlers in the same script 
and it does work.

I found this in the documentation :

The value of a script local variable is retained between handlers, but 
is lost when you quit the application, when you close the stack (unless 
its destroyStack property is false), or when the script is re-compiled.

So, if you are in one of those cases, you can use a script local 
variable.

Le Saturday, 24 Jan 2004, à 15:25 Europe/Paris, Doug Lerner a écrit :

I am seeing my "are you sure you want to shut down" twice (the
shutDownRequest handler) prompt twice now.
I think the reason for this is that I added an

insert script for stack "mainstack" into back

so I could make use of the mainstack handlers in all the stacks.

But the shutDownRequest handler looks like this:

on shutDownRequest
  answer "Are you sure you want to quit?" with "No" or "Yes"
  if it is "Yes" then
pass shutDownRequest
  end if
end shutDownRequest
I need to "pass shutDownRequest". I think the "pass shutDownRequest" 
is
passing it "up" the path and it is re-encountering itself in the
backScripts.

Any ideas of how to avoid this problem?

Thanks,

I think maybe the problem is that I ought to be sending the actual content
of the image and it's paitCompression property instead. I'll try that.

Re: A bit stuck on creating a new image

[Doug Lerner]

Well, I basically want to avoid sending LF characters along the way, which
would disrupt my communications system, which depends on LFs to terminate
the sending of a batch of data.

Except for the line wrap characters that Rev adds every 72 chars, base64
data is guaranteed not to contain linefeed charactgers.

Re: A bit stuck on creating a new image

[jbv]

Doug,

the 1st question that comes to my mind is : why do you feel the need to use
base64encode before sending before sending the data over a socket ?

I remember doing something similar last year (a client standalone was sending
imagedata to a CGI script for realtime update of web pages) and I don't
remember encoding the imagedata before sending it...

Am I missing something ?

Thanks,
JB

A bit stuck on creating a new image

[Doug Lerner]

I am sending the imageData, height, width and name of an imported paint
image over a socket.

Before sending the data I am using base64encode, and before recreating the
image on the other side I am using the base64decode of the data to set the
imageData property and also setting the height and width and name properties
of the templateImage before creating the image.

But the image comes out all scrambled in the top-left corner of the
receiving stack in the wrong size.

I tried both preserving the lfs in the base64 data and also stripping the
linefeeds, but the result is the same in both cases.

I've triple-checked the char count of the number of chars of the imageData
and the number of chars of the base64 data on both sides, before and after
encoding and decoding and everything matches.

Are there some other properties I need to be preserving besides the
imageData, width and height of the image object in order to get it right?

Thanks,

doug

Question about imageData and base64encode/decode

[Doug Lerner]

If you take the imageData of an image and base64encode it, the data is
broken up into 72 character lines.

Does this mean that the decoded data must be broken into 72 character lines
or it won't decode right?

I am doing some sending experiments, but the image that arrives is all
corrupted.

(I want to strip the LFs before sending the data over a socket).

Thanks,

dougo

Hi Dave,

Sorry to come so lae to the discussion but this
reminds me of a problem I had last year : I cloned a
stack, and the rest of the script didn't get executed.

I narrowed it down to one of the messages in the
preOpenStack/openStack/preOpenCard/openCard chain
coming to a grinding halt when passed all the way to
the engine.

However, adding a 'lock messages' didn't solve the
problem in the IDE, but it worked perfectly fine in
the standalone ; so in the end, I decided to just
suspend the IDE whenever I needed to run the script.

Maybe I should spend some time putting together a good
trouble stack.

RAM used with RunRev, Video, MIDI

[erik hansen]

it seems that for development, the mac G4 ibook
has the most compatability with video & MIDI.

in Revolution, i would like to have little
movielets where i now have 32 x 32 pixel icons
of dancers ambling around the screen in a 
scripted fashion.

16 controls with various "iconic"
video loops would require some RAM.

add even very simple MIDI patches and it
adds up. i have no idea how much RAM it takes
to operate efficiently. can i get 30 minutes
of video in there?

anyone have experience running RunRev AND
video footage in RAM?

thanks,

Erik
