Re: Transform picture

[Keisuke Miyako via 4D_Tech]

in general, I would avoid applying multiple scale transforms,
but rather,
restore the original size (scale is not resampling, the original image does not 
change)
and apply a new scale factor.

It scales correctly the first 4 times I Zoom in, after the 5th Zoom, the
scaling is no longer correct.
Zooming back out restores the correct scaling
Any Ideas what might be going wrong?

Hi Pat,

I just did a Wix database for a friend and it is pretty good. Great development 
tools for the average guy. WYSIWYG for the most part. Has many features. Full 
mobile support so it will adapt to tablet or phone or Desktop. So that’s a big 
plus. Has may tools for the store for managing contacts and processing orders. 
Great integration if you are doing a shopping cart for credit card processing 
with Stripe and also easy PayPal. Lot of options for easy coupon support, and 
“it’s on sale 20% off” type things. 

Has a mini database of course, but I did no integration work. No export or 
import work or connecting to 4D. The project was just set up a website with a 
store for a friend that wanted it to look very, very nice and have full iPhone 
and iPad support. Wix satisfied all of that. 

You’ll find it a pleasure to use and very beautiful. Great iPhone app that lets 
you deal with “chat” from the website in real time if you want to offer that 
feature. Only thing is you can only do what Wix lets you do.  If they have a 
button for it, or a menu item for it, or an option for what you want, you can 
do it, and it’s easy. If you want to do something it doesn’t provide, it’s 
super hard or you just can’t. 

So keep that in mind. As a 4D developer sometimes that is a hard pill to 
swallow. We usually get our way and build whatever we want/need. With Wix you 
use their tool. It is a website creation for mere mortals, not hard-core 
developers. 

I would recommend you get a free Wix account and try it out over the holidays. 
Spend some hours building a site and see if you like it and it does what you 
want. It is super popular so there is a lot of help and examples on the web. 
You may find out how to do automate database integration. Someone may have 
already done the hard work and you can read how they did it can copy it. You 
can upgrade to the paid version later if it meets your needs.

4D and SAML

[Nate Rheaume via 4D_Tech]

Has anyone used SAML 2.0 (Security Assertion Markup Language 2.0) with 4D? We 
are currently using the Single Sign On option in 4D but we have a customer that 
needs SAML protocol for SSO. Any information would be very helpful.

It could be that after the number of zooms the width to height ration is
wrong for how the picture is placed on the page

scaled to fit center proportional etc

Transform picture

[Peter Mew via 4D_Tech]

Hi
Im using Transform picture to Zoom in and out. Horizontally, of a graphic.
The Graphic starts out about 4500 (This will vary) pixels wide, using
transform picture to fit it in a window 930 pixels wide.
the code to zoom in is

<>ScrollRatio:=<>ScrollRatio*2 //Zoom Ratio
$ScaledL:=OrigL_3 //OrigL_3=The Original horizontal size
TRANSFORM PICTURE($ScaledL;Scale;<>ScrollRatio;1)
LeftPic_3:=$ScaledL // LeftPic_3= The displayed picture

It scales correctly the first 4 times I Zoom in, after the 5th Zoom, the
scaling is no longer correct.
Zooming back out restores the correct scaling
Any Ideas what might be going wrong?


Thanks

Re: Mojave

[Jim Hays via 4D_Tech]

We are creating various graphics using a combination of SVG, 4D HTML Tags,
and the Canvas plugin.

The SVG was originally created with Sketch on the Mac, then added HTML tags
and simplified the SVG.
We dynamically size and add text, then convert to a picture to be displayed
by Canvas.

We're only concerned about 32bit 4D for now - next year we will work on a
64bit client.
Also, we are 95% Windows, but needed a working Mac client.
We haven't investigated why some things work, and some don't - we have what
we need for now.

Good graphics - 32 bit 17HF3:

Re: Publishing a DB on the WWW. Howto.

[Pat Bensky via 4D_Tech]

We've been looking into ways to make it easy for our customers to build
custom websites using data from our 4D app (CatBase). I'm quite interested
in the Wix solution but haven't had time to properly look into it. Anybody
tried this?

Basically, you can create a database on your Wix website and populate it by
importing a csv file (AFAIK this is the only upload format currently
supported). They also have an API which will probably offer much better
opportunities for integration but I haven't looked into that yet.

Then you can build your website interface using their excellent tools - no
coding required. Create interactive forms, edit the database, etc. So the
4D developer doesn't need to know more than the basics of web
design/development and can focus on what they know best ... 4D coding :)
And the end-user should be able to easily create their website or you could
offer that as an additional service.

All theoretical of course. It's something I hope to find time to experiment
with soon (a nice little Christmas holiday project, perhaps!).
