Hi David,

Is there actually a field  on the card where
the result is found ? Once you toplevel the other
stack, you'll be in that other stack, and simple
control references are considered relative to tha
stock, not the new stack.
So a possible solution is the use o the long ID :
--
  put the drawnumber of this card into temp2
  put the long ID of fld temp2 into tFieldLongID
  toplevel stack "draw lists"
  find temp1
  put empty into fld tFieldLongID
--

Hope this helped,

Jan Schenkel.

Wuold you be able to write an external to copy and paste a selection of 
an image with a transparent background in Revolution?
This wuold be great... at the moment if you select with the selection 
tool part of one image with a transparent background and you copy it 
into an other image you will get a white square.

I'm highly interested in your code, as I might do something
quite similar for a client soon.
I missed a part of this thread though, hence my question :
is your xTalk script running as a client app or as a CGI script
on a server responding to requests sent from a browser ?

In the project I might work on next month, various tasks will need
to be done, including on-the-fly generation of PDF docs; that's why
I'd prefer to use MC as CGI rather than Perl of PHP (as such onthefly
generation of docs is easier - by several orders of magnitude - to do
with xTalk).
End users will also have the possibility to deposit some money (via their
CC#) on a personal account, for which I'd like to provide some online
management tools (mostly : history). Obviously, such online tools
require secure connections via SSL / https, and I guess there's no
hope to manage such process from MC/Rev as CGI...

Best,
JB

Yes, that card has a field with the name that is the

Thanks, but I don't think so.  There's no field 
in the card of the stack which contains the custom
property providing input to the variable, temp2.  But the
problem, it seem to me, is using the value drawn from a
customproperty, putting it into a variable and then trying
to access a field of that name.  Since the button is part of
a background, and the value of the custom property will
vary, I don't see how working IDs into the mix will be viable.

Thanks Geoff.  One interesting use of this would be for drag and drop.  
You could display a windowshaped window that is partially transparent 
when the user clicks on something that can be dragged.  This would be 
similar to what the finder and Windows Explorer do.

One request I received was to be able to apply a grayscale (8 bit) 
image to a stack window for transparency (Rev supports 1 bit).  This 
would make the effect I describe above even cleaner looking.

I assume you mean the 'Compositing Example' stack, yes? It's very cool, and
I will need to study what happens.

What's really needed is a full-blown image processor plugin, eh?

> I have something, but it is ugly and really needs nested arrays.

Nested arrays? Do you mean you are creating some paint tools to accomplish
these tasks? Perhaps by examining what's under the tool point, changing the
arrays and redrawing when you save?

If I 'export snapshot' into an 'image' will it automatically convert to an
image format, i.e., Rev's own 1-byte proprietary format?

If so, then I think I see a little of what you mean. If we use a proprietary
method, we *should* be able to do this:

1) If we can 'export snapshot' into an image, it should produce an 8-bit
image rectangle with white pixels outside the paint area to the edges of the
rectangle.

2) Use the maskData property to set all the white pixels to transparent.

3) In order to facilitate a mask I can understand when I see it, I will want
to change all non-transparent pixels to black (or some other 8-bit color to
distinguish it from overlaid images for alignment purposes) during the
process.

You still have to go through every pixel and re-render, right?

All this could be solved with a zoom control, a lasso tool, and some pixel
controls in Rev's Paint Palette, so that's on my wish list.
 
> Think the weatherman before a bluescreen.

Hmmm...must be a Windows thing. Being a Mac person, I've never seen a
'bluescreen'. Mac Sad Face, yes, Chimes of Death, yes, but no BlueScreen ;-)

> I made the same ID mistake, BTW.

I'd be willing to bet that everyone does the first time they use it.

I understand that in this case there is nothing but an image ID to set the
stack to, but IMO it's still an unexpected deviation from the usual syntax.
I mean, looking at a script, you could easily mistake setting the stack to
another stack ID or something, without the designation of "image" or
"stack". 

Thanks much,
Ken N.

More image processing

[Ken Norris]

Howdy,

On the Mac, what type of thing is an image in the clipboard?

on a Windows PC, what type of thing is an image in the clipboard?

What type of 'image' is the paint area of a Rev 1-byte/pixel image?

What type of 'image' is an image area pasted into a Rev image from the
clipboard?

What I did was copy an all black image from a HyperCard Color Tools external
pict editor and paste it into a Rev image. I didn't even know if it would
show up, but it did.

Now, I want to make it a windowShape mask.

I'm assuming I can go through the pixels and set all the white ones outside
the black area to transparent, but how do I retrieve the rectangular size of
the pasted area?

I know that's a few questions, so just pick your choices.

What about movieFrame.top and movieFrame.left ? Are there set to Zero ?

Otherwise, change the returned image size

rdata.length = (movieFrame.right-movieFrame.left) * 
(movieFrame.bottom-movieFrame.top) * 4;

Re: USB mics supported by Record?

[Dan Soneson]

Any of you have success with USB mics and the record sound command?

Hi Richard,

I have had no trouble using a microphone headset plugged into an iMic. 
I do not use Revolution to set the input, however. I leave that up to 
the sound system preferences panel. I think I have even used a regular 
USB microphone and recorded nicely using OSX. I am still a bit shaky on 
using Rev in a standalone to record sound, but in the development 
environment everything works fine.

What system are you trying this with? Is the trouble present in the 
development environment or only in a standalone application?

What's really needed is a full-blown image processor plugin, eh?
Yeah.  And maybe based on a library.


I have something, but it is ugly and really needs nested arrays.

Nested arrays? Do you mean you are creating some paint tools to 
accomplish
these tasks? Perhaps by examining what's under the tool point, 
changing the
arrays and redrawing when you save?
I got a little mixed up.

I want to have an image type or value.  An array as representation is a 
problem because I can't do this (at this time):

  get tint( over(img1,img2), 20)

So the first thing I want is to allow arrays to be full values.  I want 
a function to be able to return an array and in the same expression 
allow the array returned to be a parameter for another function.

I thought about putting pixel values into a nested array, but it might 
work to leave them at the highest level.  The problem with that is that 
full array operations would not work.  So, if pixel values are arrays, 
then it would be good if all the functions I need are array operations.

However, I have done well with packed numerical "arrays" that are 
implemented as binary strings.  The problem here is random access in 
changing values.  I have a feature request in that would make this much 
faster.  It would apply to any case of a substring being replaced with 
a string of the same length.

So any of those three wishes will help and all will.

However, if I finish this up, and I don't have those, then I will 
probably use "boxes" (arbitrarily nestable chunks that can be strings 
or binary or numbers or arrays) and I need to rebuild that.


You might also consider taking a picture with export snapshot to a
variable and then looking for white or some other color to make
transparent parts in the final picture.

If I 'export snapshot' into an 'image' will it automatically convert 
to an
image format, i.e., Rev's own 1-byte proprietary format?
I don't know.  I export to a variable as PNG.  I suspect this is the 
same as a PNG file, but I have not checked.  I set the text property of 
the image to the variable value.  An image shows up.  I don't know 
about the proprietary format.

I have gotten the impression that an image is stored as the original 
form and that is exploded for imageData, maskData and AlphaData, and 
perhaps for display.  If the image is modified then the exploded image 
is compressed as PNG.  I can be compressed as other formats when saved 
to disk.  The fact that there is both maskData and alphaData might mean 
there are alternate internal compressed formats or they might be 
historical.  I think I heard something about the first.  This is all 
much more than I know and is all guessing and vague memories.

By 8-bit do you mean a color table?  Does this mean I can lose colors 
if I modify an image with lots of colors and then save it?

If so, then I think I see a little of what you mean. If we use a 
proprietary
method, we *should* be able to do this:

1) If we can 'export snapshot' into an image, it should produce an 
8-bit
image rectangle with white pixels outside the paint area to the edges 
of the
rectangle.
Except I don't know about "8-bit", I'd say yes.

2) Use the maskData property to set all the white pixels to 
transparent.
Yes.  You can also apply this to images you import.  You might also get 
a little more complicated and consider colors almost white and pixels 
with a very low alpha.  Some images have picture or other data under 
transparent portions.

3) In order to facilitate a mask I can understand when I see it, I 
will want
to change all non-transparent pixels to black (or some other 8-bit 
color to
distinguish it from overlaid images for alignment purposes) during the
process.
That is OK.

You still have to go through every pixel and re-render, right?
Yes, but in the simplest case, you build a new maskData based on image 
data.  It will be fastest to accumulate in order.  This build does not 
need to know the height and width (formatted) because it makes a pixel 
transformation.

All this could be solved with a zoom control, a lasso tool, and some 
pixel
controls in Rev's Paint Palette, so that's on my wish list.
I think Photoshop has a magic eraser that effectively is a pour 
(paint-bucket) with a transparent color.  Something like that or 
allowing a transparent background would address this.  Or allow 
selecting transparency (alpha) in colors.

I understand that in this case there is nothing but an image ID to set 
the
stack to, but IMO it's still an unexpected deviation from the usual 
syntax.
I mean, looking at a script, you could easily mistake setting the 
stack to
another stack ID or something, without the designation of "image" or
"stack".
I thought that since an image ID is specified and not an image that the 
windowShape would follow the image.  That is a change to the image 
would show up in the windowShape.  In my

I agree.  An intrepid plugin tinkerer might be able to implement this 
in the mean time.  It might be possible to put such  image data on the 
stack packed into a string.

(I have seen other cases in which transparency is lost, but I don't 
know enough about Revolution images to guess why.  I suspect they are 
being coerced to an image type they should not be coerced to.)

Another good one would be the ability to paste images from other apps 
as actual size.  Now that might take an external to help, I don't know.

The size of an image is the formatted width and the formatted height.  
If it hasn't been resized, that is the height and width.  (Yikes, I 
think that means I may have said something wrong about Trevor's 
problem.)

However, to do the white to transparent transform, you don't need to 
know.  Each pixel in imageData is four chars.  Each pixel in maskData 
is one char.  The number of pixels are the same.  Create a string 
adding one mask byte for each four image bytes.  Then set the maskData. 
 (All brain fluff; I have not done this, yet.)

RE: USB mics supported by Record?

[michael]

Hi Richard,

I haven't tried Rev on a Mac but on Windows if it's using QuickTime for recording, 
there is a lag between the time you hit record and it actually starts to record, 
presumably because it's loading QuickTime. I imagine on the Mac there wouldn't be a 
delay. I made a little test app for doing recording and it works in the development 
and when I built the app and tested on a couple of machines. And the delay in the 
recording start was apparent on the 3 machines I tested. This was without a USB 
microphone.

Are you on a PC or a Mac?

From clipboardData in the Transcript Dictionary, these are _virtually_

What type of 'image' is an image area pasted into a Rev image from the
clipboard?
I would guess PNG, then.  Maybe it can be saved as PNG and then that 
compared to the text of the image.  If equal, it was probably saved as 
PNG.

Referencing cells by column and row name

Say I have 50 lines of tab-delimited data.  Each line represents one of the 50 U.S. 
states.  Each item within a line corresponds to some kind of data (population, area, 
etc.)  Is there any way using Rev's built-in commands to write something akin to

where Population and Colorado are not variables, but 'column' and 'row' names.  Is it 
possible to establish names in this way and retrieve data similarly to above?

(I'm assuming the item delimiter is adjusted appropriately for item 
chunks.)

1.
Make Population and Colorado constants, or, if this must work among 
many scripts, globals set in initialization.

   get item Population of line Colorado of currentData

2.
Set up global arrays in initialization.
   get item data["Population"] of line state["Colorado"] of currentData

3.
Use functions.  The state function returns a line.  The datum function 
returns an item from a line.  The data is in a global.  Can't be used 
to change the value.

   get datum("Population", state("Colorado") )

4.
Use a function for each datum or state.  Colorado() returns the 
colorado line.  Population() returns the Pop item.  The data is in a 
global.  Can't be used to change the value.

   get Population( Colorado() )

5.
Switch to arrays.  The data array is in a global named data.
   get data["Population","Colorado"]

6.
Make an interpreter.  Replace item key words like "Population" with 
"item 4" and line key words like "Colorado" with "line 7 of stateData". 
 Then "do".

   MarkDo "get Population of Colorado"

That's enough to get you thinking, I hope.

Especially if they can swing a few extras into it, like text shading, making
shape blends, controlling lighting effects, and placing text and images on
3D surfaces -- 4 really common uses of any reasonably modern paint program.

The problems for me come when I try to import something from one of my cheap
external paint programs that just don't show up properly in Rev images,
mainly because of cross-platform compatibility I think. I end up having to
additionally take them into PhotoShop or somewhere else and resetting
filetypes. Very time consuming experiments.

Well, like I said, I'm only concerned with maskData at this juncture. I
don't know what the dynamic color range of a regular PNG is. If it is higher
than 8-bit, then it probably can't be used as a mask for windowShapes,
unless Rev somehow switches it into a Rev-proprietary 8-bit inmage.

??? This is what I don't understand. How does it work? ImageData is a 32-bit
thing, 4 bytes/pixel. According to the docs, maskData is 8-bit (1
byte/pixel) only. I mean, sure, you can make a pixel which only uses 8 of
its 32 bits, but that doesn't change it's actual depth, IOW, it's still a 32
bit pixel, and I would think that any image made with it cannot be used as
maskData unless you convert it somehow.

So, is this the "transformation" you speak of? Again, how does it work? I
haven't succeeded in making an 8-bit mask from a 32-bit image in Rev. I can
do it very easily in other Mac-only venues, but not here, so far.

As much as I like industrial illustration, I guess I just have too much
artist in me. This is causing more brain-fade than I can handle for just
wanting a simple mask to precisely align with an imported windowShape image
without going through several other applications to create it.

I much appreciate your patience. I hope I can get my head wrapped around it
soon, or that someone comes up with a better approach.

Thanks,
Ken N.

Have you tried GraphicConverter?



I have PhotoShop 7, rarely use it.  I create sliced graphics and UI elements
in Firewoks, but for simple touch-ups and convrsions I've not found anything
as efficient as the modestly-priced GraphicConverter. Best $35 investment I
ever made.

Off the top of my head...  This may take some fiddling to make work.

-- This function takes an imageData and the r,g,b of the color to be 
made transparent (key).
-- It returns a value suitable for maskData.
function maskOfImage imageD, r, g, b
local transp, opaq, maskD

  put null into transp
  put numToChar(255) into opaq
  put empty into maskD  -- not needed
  repeat with i= 1 to size(imageD) step 4
 if (char i to i+3 of imageD) contains colorKey then  -- equals
put transp after maskD
 else
put opaq after maskD
 end if
  end repeat
  return maskD
end maskOfImage

Something like that.  It might be a byte too long or too short.

I use 'contains' instead of 'is' to avoid consideration of the string 
as a number.  There was a bug in which numbers could start with null 
and I don't know if the fix got into the latest version.  It has an 
unspecified target milestone.  I don't know how to interpret the 
Bugzilla target milestones, anyway.

That would be a good addition.  For images that are stored internally 
copying and pasting from your graphics app would be very handy.  You 
could probably create a plugin with a button that pasted the current 
clipboard into an image of the current stack.
I wonder what this would do?

  create image
  set the text of the last image to clipboard["image"]
This seems to do it, except the PNG image seems to be flawed.  Rats.
