Ink Control on a report w/ background

[mikeallenbrown]

Has anyone had any luck with the printing of an Ink control in a report WITH the saved background?

I've confirmed that the background image is being saved in the ink control. All I get in my report are the markings however.

Using 4584_4961.

Re: Ink Control on a report w/ background

What method are you using to set the background image of the Ink control ?

Re: Ink Control on a report w/ background

I think it's inherent of the control. When I look at the data in SQL I see it referenced there. And to be honest I haven't looked into this more. I may totally be wrong.

Re: Ink Control on a report w/ background

Try to set your background using code :

Create a callback function :

function xb as c (e as p)
dim fn as c

fn = "c:\dump\body-diagram.png"
dim b as b
b = file.to_blob(fn)
dim b64 as c
b64 = base64encode(b)
b64 = "data:image/png;base64," + b64

dim js as c
js = <<%str%
var inkObj = {dialog.Object}.getControl('INK1');
var _obj = {save: true, image: {data: '__b64__'}};
inkObj.setBackground(_obj);
%str%

js = stritran(js, "__b64__", js_escape(b64))

xb = js
end function

Then use a button to execute callback.

Have you watched the Alpha video UXINK_V12--5 ?
That video helped me.

Also, How do you get your ink data/field on a report ?

Re: Ink Control on a report w/ background

I would also like to know how to do this?

There doesn't seem to be any instructions on putting ink data on a report, which would be a really nice thing to be able to do.

Re: Ink Control on a report w/ background

I followed post #4 suggestion. Now the background saves where as before it did not.

As for the report I've gotten it to work too BUT the image is cut off. In the data source section of the report I've overridden the column to "INK Image". On the report itself I've "sized to fit" and tried various height/width combinations. Most of the image is there but not all. Still trying to determine what I'm missing.

Re: Ink Control on a report w/ background

For what its worth, I have sent in a request to Alpha asking if they could demonstrate how to do this in one of their Q&A Webinars.

Re: Ink Control on a report w/ background

To solve that I did a work around (It works for me .....not 100% happy with it though, i hope there is an easier way):

I placed a bitmap object on my report and in "Filename" property of the bitmap object I called the following function in the "Dynamic" section:

ink_page(ink)

(where ink is the field storing the ink text)

Defintion of the function is :


FUNCTION ink_page AS C (ink AS C)
' Parameters:
' ink - ink image in the form of text

dim fn_png as c
dim fn_bmp as c
dim fn as C

fn = FILE.TEMP_PATH_GET() + "ink_" + A5ws_GetCurrentUser()

fn_png = fn + ".png"
fn_bmp = fn + ".bmp"

a5_ink_to_png(ink, 792 ,612, fn_png, .T.)


dim img as B
dim img2 as B
dim fptr as P
dim fptr2 as P
dim length as N
fptr = file.open(fn_png, FILE_RW_EXCLUSIVE)
length = fptr.bytes_get()
img = fptr.readb(length)
img2 = png_to_bitmap(img)
fptr2 = file.create(fn_bmp, FILE_RW_EXCLUSIVE)
fptr2.writeb(img2)
fptr2.close()
fptr.close()

ink_page = fn_bmp
END FUNCTION

Re: Ink Control on a report w/ background

Robert, where are you placing the actual function code?

[mikeallenbrown]

Re: Ink Control on a report w/ background

Interesting, Robert. I could probably use this a5_ink_to_png() function in my ink component to save a png image to the same SQL table the ink control uses. Then just use that in the report.

I placed the function in the global function section of my project.
i.e. Control Panel / Code

A-ha! That's perfect, this video shows the trick to putting the ink onto a report at the 25:45 minute mark. I would never have figured this out, it is simple but not at all obvious.

Rendering the ink over a background image is shown at 38:40

Thanks very much William
