Reset Image field after a Photo has been taken via Camera

Posted on by Community Power Pla... Microsoft Employee

Hi,

New to Power Apps and like a lot of people I have seen on the forum I have been asked to build an app. One of the criteria of the app is that the camera function of power apps must be used.

Like the Title says I am having issues resetting an image that is linked to a camera.

Set Up:

Dropdown controls which camera the user wants to use on the device.

The Camera then uses which ever camera is selected from the drop down. You need to select the camera field in order to take the picture.

The photo that is taken then shows on an image field, you can retake the picture and the image field will change accordingly.

Before the image is taken the Image field is transparent and does not appear.

Issue

The issue I am having is that I do not know how to reset the image field after a picture has been taken. I would Ideally need the image field to revert back to its original status of being transparent and not hold any Photo's that have been taken.

I have added a button and tried the following "OnSelect (property) Reset(Image4)" this has not worked but unfortunately I do not know the functions that would be best for the task.

Any help on this would be appriciated.

Thanks

Hey! You are using Camera1.Stream, right?
If yes, set a var

Set(varPhoto, Camera1.Stream)

If u want to re take the picture, click on a trash icon and set the OnSelect to Set(varPhoto, "")

That will reset the photo 🙂

@Nogueira1306

Thanks for the quick reply.

I have not specifically set out to use Camera1.Sream.

So just to confirm does the Set(varPhoto, Camera1.Stream) function need to be in the OnStream property of the Camera?

I have added the Set(varPhoto,"") to the OnSelect property of the button, and no errors have shown.

Thanks

1. Insert a Camera Control and set the StreamRate to 50 or 100;
2. Add an icon (can also be the Camera Control) and write to OnSelect: Set(varPhoto; Camera1.Stream)
3. Add an Image and set the image as the variable we created (varPhoto)
4. Add an Icon to delete the image and write on OnSelect: Set(varPhoto; "")

Hi @Nogueira1306 , thanks again for your help.

I am not sure what I am doing wrong here.

I have added the camera control and set the stream rate to 100 (also tried at 50).

The 'set(varPhoto; Camera9.Stream) in the 'OnSelect' property shows an error, "the formula contains 'Ident' when a 'Function' is expected".

adding "varPhoto" was accepted.

adding set(varPhoto, "") in the on select function was selected.

Thanks

You have
Set(varPhoto; Camera9.Stream)

And it should be

Set(varPhoto, Camera9.Stream)

Plus, I would recomend you do it on an icon and not on the camera control

You're 100% correct.

I will add the Set(varPhoto, Camera9.Stream) to an icon, but I am limited for space due to the app requirements.

Thank You for your help.
