Seems fixed but I'll need to rerun the check at some point to confirm.
Thanks again everyone!

Hello again,

Process works, although I do have to manually rename and reposition the
images pasted into v17.

Shouldn't take too long...

Re: Converting pictures

[Alan Tilson via 4D_Tech]

Hello John, Ernie & Chuck,

Thank you for your responses. I'm just getting back to this...

I have 38 instances I believe of static PICT images in our v17 db. So while
I'd love to automate this it is not so big really that I can't just work
through it.

John - I tried your code but it doesn't work. It runs but when I paste the
image back onto the form it is the same .pict image. I suspect that I need
to run this in v13 and then paste the results into v17. I'll try that. But
I seem to remember that the transparency code needs to run in v17. So maybe
I need 2 steps...

Ernie - I like the idea of converting my static pictures into library
pictures, but I suspect I'll have the same v13/v17 issues. I do have some
v13 code to convert the library pictures and some v17 code to set the
transparency.

Chuck - do you think this would be a v17 component that would simplify this
process? I do plan to try the v13/v17 idea first I suppose.

Thanks again,
Alan

Re: Converting pictures

[JOHN BAUGHMAN via 4D_Tech]

What I did was cut each picture off the form to the pasteboard run the 
following code then paste it back into the form…

C_PICTURE($picture_c)
GET PICTURE FROM PASTEBOARD($picture_c)
  // convert the picture
CONVERT PICTURE($picture_c;".png")

  // make all white pixels transparent
TRANSFORM PICTURE($picture_c;Transparency;0x00FF)

SET PICTURE TO PASTEBOARD($picture_c)

Perhaps the is a way to automate this but just did it manually.

Hello everyone,

Is there code that can convert static PICT images to PNG, images not in a
library?

Hi Setar,

The v13 code to convert PICT -> PNG is here: http://kb.4d.com/assetid=76775
^ There is no transparency option in that code.

While the following code was published for v16: http://kb.4d.com/assetid=77963
^ This one uses the transparency option.

Regarding 4D Pack, it should exist in v16 but it is no longer available in

We had resolved this by using the picture conversion method from a tech note or 
tech tip…not sure if it’s the one others pointed out, but we did have to use 
that to export our entire picture library out to PNG files and get the 
transparency.

I use Paint.net. It’s shareware.

I have used it many times to create a transparent background.

Subject: Converting pictures on 4D forms (Windows) to get transparency

Hi Everyone,

I'm in the process of going through a database to convert all the 
pictures, icons, and such in it so I can use the database with 64-bit 4D 
v16 (and eventually v17).

The documentation is pretty clear that even though any images pasted in 
did not start life as PICTS - and I'm talking about things like arrows, 
some icons, line drawings, navigation tools, etc., that are part of the 
user interface, not actual photo type pictures -  4D would receive and 
store them as PICTS, so you have to find each one and convert it.

To do this, I'm using JPR's Picture Conversion utility that he provided on 
the 2017 4D Road Tour.  It does a fine job as it can scan all the forms, 
find the offending pictures, list them, and then provides a utility where 
you can either convert them and put them into the picture library or 
convert them and put them into an external folder.
 
One thing I'm finding is that the conversion doesn't support transparency, 
so I end up with pictures that have white backgrounds, which doesn't look 
nice.  Here is part of a thread from me to JPR:

Me: When I drag a Static Picture to the converter, then back to the form, 
it seems to lose its transparency, even though the 'Transparent' property 
is turned ON.  How can this be fixed?
JPR> It cannot. The transparency done previously by 4D was just a trick 
replacing the white pixels with the background color dynamically, because 
the concept of transparency didn't exist at this time (like in PICT, JPEG, 
etc.) 
JPR> Now 4D uses the modern toolbox which relies on the picture 
transparency information coming from the alpha channel. So if you want 
transparent pictures, you must convert into a format supporting alpha 
channel (like PNG) and use any software able to add the alpha layer to 
your pictures.  On Mac, the simplest one to add alpha channel is 
PaintBrush (from Soggy Waffles). You add transparency with the paint Fill 
tool


The problem is that I'm on Windows.  Does anyone have a recommendation for 
fast technique that they've used that supports this "alpha channel' so I 
can convert my non-transparent images so that they are transparent again? 
It looks so bad having an arrow on a form with a big white background.

Thank you -

Hi Bob,

2 suggestions:

Buy a MacMini for the office.
Hire a Mac developper for 1 day to arrange all that.

Re: Converting pictures on 4D forms (Windows) to get transparency

[Bob Miller via 4D_Tech]

Thanks to all who replied so far.  I've been trying different things.

Vance - RE: Can you make a picture have an opaque effect?

This isn't what I want to do; the pictures have an opaque effect where the 
white backgrounds are opaque when what I want is for the background to be 
transparent, so the icon does not appear to have a square border.  If the 
background is transparent, the icon can sit on the form and the color of 
the form surrounds the icon, which looks better.


Randy - RE: You can use the MSC in v16 to flush out all the forms

Yes, this works well, and JPR's component does a lot of the same thing. In 
working out the problems, I found however that what looked to be a 
transparent background in 32 bit is not transparent in 64 bit (see above, 
I now have a white box around many of my icons), so I think I need an 
external drawing program to somehow convert the white background to 
"transparent".


Cannon - Thanks, I had not seen that tech note.  I'm already in v15 and do 
not have the plugin, so I tried using the same concept on a single member 
of the picture library that I knew had a transparency issue.  The result 
was that the entire picture became transparent, so something clearly (to 
make a pun) went wrong!  I'll investigate this a bit more, but I'm afraid 
that what I really need is something that can 'lasso' an image to find the 
outermost border, then set everything outside that border to transparent - 
which would be tough to do in code.

Keep those ideas coming!

Re: Converting pictures on 4D forms (Windows) to get transparency

[Randy Jaynes via 4D_Tech]

Bob,

You can use the MSC in v16 to flush out all the forms where bad pictures are 
located, as well as bad picture library items and their references.

Then use the picture conversion routine mentioned to convert the pictures to 
PNGs. We did this a couple months ago to prepare for our move to v16 and it 
worked well.

After doing all this, I discovered that there will also be potential issues 
with logos and pictures that you allowed users to put into their data. When you 
display the picture fields on a form, if the it is in PICT format you'll get 
that pretty camera with an X through it. ;-)

At any rate, start with the MSC in v16. It will quickly and easily point out 
what you need to fix in your structure.

HTH,
Randy

RE: Converting pictures on 4D forms (Windows) to get transparency

Hi Bob,

Can you make a picture have an opaque effect?

Subject: Converting pictures on 4D forms (Windows) to get transparency

Hi Everyone,

I'm in the process of going through a database to convert all the
pictures, icons, and such in it so I can use the database with 64-bit 4D
v16 (and eventually v17).

The documentation is pretty clear that even though any images pasted in
did not start life as PICTS - and I'm talking about things like arrows,
some icons, line drawings, navigation tools, etc., that are part of the
user interface, not actual photo type pictures -  4D would receive and
store them as PICTS, so you have to find each one and convert it.

To do this, I'm using JPR's Picture Conversion utility that he provided on
the 2017 4D Road Tour.  It does a fine job as it can scan all the forms,
find the offending pictures, list them, and then provides a utility where
you can either convert them and put them into the picture library or
convert them and put them into an external folder.

One thing I'm finding is that the conversion doesn't support transparency,
so I end up with pictures that have white backgrounds, which doesn't look
nice.  Here is part of a thread from me to JPR:

Me: When I drag a Static Picture to the converter, then back to the form,
it seems to lose its transparency, even though the 'Transparent' property
is turned ON.  How can this be fixed?
JPR> It cannot. The transparency done previously by 4D was just a trick
replacing the white pixels with the background color dynamically, because
the concept of transparency didn't exist at this time (like in PICT, JPEG,
etc.)
JPR> Now 4D uses the modern toolbox which relies on the picture
transparency information coming from the alpha channel. So if you want
transparent pictures, you must convert into a format supporting alpha
channel (like PNG) and use any software able to add the alpha layer to
your pictures.  On Mac, the simplest one to add alpha channel is
PaintBrush (from Soggy Waffles). You add transparency with the paint Fill
tool


The problem is that I'm on Windows.  Does anyone have a recommendation for
fast technique that they've used that supports this "alpha channel' so I
can convert my non-transparent images so that they are transparent again?
It looks so bad having an arrow on a form with a big white background.

Thank you -
