Issues with picture attributes

Rennur

I'm having a few issues with picture attributes & was hoping if anyone could kindly assist.

a) A shortcut to picture attribute is not displaying the picture when opened in the browser.
e.g Business object Docket containing the Signature reference

b) Form HTML cell truncating everything including the = sign for the src='<<bo.Base64stringSC'. Blue part is truncated.

In the browser:

image src truncated

Note: tried using double quotes (") or single ( ' ) & mixture (as in in pic) to no avail.

Thanks

Hi Rennur,
I am using picture shortcuts successfully so they work for me and this might be some combination of attributes, shortcuts, images you are using hich is causing the problem (See you´re trying to do something in your screenshot but can´t fully make out what. I don´t know if the issue is related to you possible trying to show the image of a signature you the system haven't saved yet (or which haven't been entered yet).

Haven´t used the IMAGE_DATA function yet so can´t help there.

Thanks for the input Henrik.

The business object is created and saved. The signature image and the attribute containing the is saved base64 string are all saved in DB, i checked.

Hi Rennur,

For problem b and If I understand what your trying to do....

Try to do away with the html img tag you are using and just insert the AWIM tag instead, see if that works.

For example, instead of :

<img src="<<Docket.SignatureB64SC>>" width='300' height='150'>

Just use:

<<Docket.SignatureB64SC>>

You will have to use a second attribute to hold a copy of the image if you want to control the size of the image. eg Docket.SignatureSized=SCALE_IMAGE(Docket.SignatureB64SC, 300, 150) (off the top of my head!)

See my last post in this thread for my experience:

Hope this helps

Fixed in v5.9 1898.
Direct shortcuts in object forms color=green[/color]

Not supported yet (v5.9)
Direct shortcuts in object form's HTML cells (including IMAGE_DATA function that uses shortcuts) (C1, C3, C4)

References in HTML cells are not supported and cannot be used. (C2, C5)

Hello Rennur,

I just had a somewhat similar issue with Signatures. I have a signature attribute on the form and I sign the box using the mouse and then want to scale it and display it on the form.
I use the SCALE_IMAGE function. I have noticed that this function scales the regular pictures but for signatures it does not work appropriately. I just displays a black band for the scaled version.
I was not sure if you have encountered the same sometime. But since I see a lot of posts in your name, and this one was specific to signatures, I thought I would just ask you as well.
I did not get much help from the support on this. I am using AwareIM 5.9 Build 1893. Not sure if this is a bug in that version.

Appreciate your inputs.

Thanks

Hi itzramaware,

Welcome to the forum.

I've just tested out the SCALE_IMAGE function on the signature picture attribute.
The result is a scaled picture with the the specified dimensions.
The signature drawn is displayed properly.
The file saved is the database is .jpeg

I don't see any issues.

Cheers

Hi Rennur,

Thank you for your email. Here is a screenshot of what I am trying to do

URL: http://tinypic.com/r/ibgv3r/8

I have a business object which has the attributes Signature and Sig_Scaled both of which are Picture attributes having the "Picture Represents Signature" box checked. I display both of them on the form and when the user signs the Signature attribute with the mouse and saves the form, I have a rule at the save of the form.

Patient_Forms.Sig_Scaled=SCALE_IMAGE(Patient_Forms.Signature,60,30)

I am storing the scaled image in Sig_Scaled attribute. Upon clicking the Save button, this rule is executed and the Sig_Scaled attribute is populated as a black band as shown in the screenshot. The main signature is stored in the database as .png while the scaled image is stored as .jpeg format.

Everything seems fine but only the display part is not working. It worked perfect when the picture was not a signature. But when I check the "Picture Represents Signature" checkbox, only the original signature is displayed; not the scaled one.

I am using AwareIM Professional Edition Version 5.9 Build 1893. Which version are you using? Is it any different from what you tried? Am I going wrong somewhere? Do you have your screen shots as well?

Appreciate your inputs.

Thanks!

Itzramaware,
When looking at your screenshot (and also from reading your post) it seems as though the attribute Sig_Scaled also is configured to be a signature picture attribute. Try having the Sig_Scaled attribute as a ordinary picture (i.e non signature) attribute.

Rennur

If Scaled image attribute is not used to capture a signature why does it need to have the signature checkbox ticked?

Hello!
Well I had tried that before too but it still does not make any difference. I should have posted this before.

Please check if you are able to download the BSV. http://we.tl/5Wl67VWAUk
If yes, then it is just a matter of creating a new Patient_Forms object and then editing it on AwareIM.

I appreciate any inputs form your end. Hope to hear from you.

Thanks!

Come to think about it, I THINK (can´t fully recall) I have experienced this before and the problem is the scaling of PNG files. Try downloading the saved signature PNG file, convert it to a JPG file (real convert not just rename extension), upload it to the attribute and then try scaling it. This could help in identifying the potential bug.

If anyone has seen this or has successfully scaled PNG´s, please comment. Another thing you could test is uploading any "true" PNG file to an attribute and try scaling it.

Rennur, in your post you write about a test you did, did you successfully scale a saved signature image? If so i.e. works for you and not Itzrmaware (and me previously with PNG´s) it might be a server specific error?

Another note and something to try to try to identify the bug. I had this problem when trying to scale an uploaded logo file and I THINK the file had a transparent background and this might be the problem. Try scaling a "true" PNG file with a transparent background. I also found this after googling this issue:
http://wordpress.stackexchange.com/questions/40724/png-with-transparent-background-turns-black-when-uploaded-and-resized

Rennur

I've had issues with using transparent background PNGs with the report designer before.

Make the signature pad use a white background. http://bit.ly/aimdevres (scroll down to the bottom)

Great! The suggested modification by Rennur works perfect !

Thank you all for your time! 🙂

Thanks again!!
