Hiya there!

My first time posting here, am hoping someone can point me in the right direction smile

I have a live mobile application running which is successfully deployed online. It has been developed in the latest PB2019 Build 2082. I am running it through 4G on my mobile phone, but I am struggling when it comes to taking photos. I've attached the appeon_workarounds.pbl and use it to create my eon_appeon_resize statements to make everything look the right size, this has worked really well. I declare my eon_appeon_resize ieon_resize in the global variables and create the ieon_resize = create eon_appeon_resize. Then when I open any new window, the resizing can be called easily.

But I am not sure how I make a new window that shows what the camera is showing? I'd then like a button to capture that live image, then resize it a bit and send it to the wwwroot folder on the server into a particular folder with a specific name.

I've been following Fili Sosa's https://www.youtube.com/watch?v=41JdieCvog8 youtube video, but he doesn't go into enough detail for me at the 55min 40sec area.

So as a summary I'd like to:

  1. Know which global variables to define & which objects to create
  2. Know what I must use to display the current image from the phone/tablets rear camera
  3. Know what the button script must contain to capture an image and send it to wwwroot/folder

 

Many thanks and king regards

Hi Marc;

   Here is the code that I use in my Mobile App for interacting with the camera ...

eon_mobile_str_cameraoption        lstr_camera
Integer        li_file_type  =  0    // Photo Only
Integer        li_rc

IF  rb_photo.checked = TRUE  THEN
    lstr_camera.i_filetype        =    1
else
    lstr_camera.i_filetype        =    2
END IF
lstr_camera.b_allowedit = cbx_edit.checked
li_rc    =    io_camera.of_takefile ( lstr_camera , sle_cam_file.text )
st_cam_rc.text  = st_cam_rc.tag  + String (li_rc)
IF  li_rc    = 1 THEN
    pc_photo.picturename = sle_cam_file.text
else
    pc_photo.picturename = ""
END IF

HTH

Regards ... Chris

Thanks Chris, just getting a bit stuck on io_camera.takefile, getting the following error

"Warning C0014: Undefined variable: io_camera"



What i've done so far

● Declared the eon_mobile_str_cameraoption lstr_camera in my global variables of the project

● Added the integer variables into open statement of my window

● Inserted a photo named it p_photo

● Inserted check box called cbx_edit

● Inserted single line edit called sle_cam_file

● Inserted to window open statement lstr_camera.i_filetype = 1

● Inserted to window open statement lstr_camera.b_allowedit = cbx_edit.checked

● Inserted to window open statement li_rc = io_camera.of_takefile ( lstr_camera , sle_cam_file.text )



Then that is when I get the Undefined variable. Do I need to add a non-visual object?

Apologies - still a bit of a PB amateur here :)

Hi Marc;

The "io" prefix naming convention I use stands for "Instance of an Object". Here is my code for that ...



Instance Declaration:

eon_mobile_cameraex io_camera



Open or Constructor Event:

io_camera = CREATE eon_mobile_cameraex // Instantiate camera helper!

Thanks, I have been trying to get the image from camera into a picture box.

So if you create a picture box, with a button to take a photo, then insert this code below into your button, it should do the trick, you will also need to create some instance variables for the window you're working in which I will also show below.

MY TAKE IMAGE BUTTON CODE

string ls_filepath="", ls_newfile=""
boolean ib_edit_photo
integer lstr_is_photo

lstr_option.i_filetype = 1
lstr_option.b_allowedit = true
leon_camera = create eon_mobile_cameraex
leon_camera.of_takefile( lstr_option,ls_filepath )

is_photo1 = ls_filepath

leon_image = create eon_mobile_imageex
ls_newfile = ls_filepath
leon_str_image.l_width = 125
leon_str_image.l_height = 150
leon_str_image.b_existoverwrite = true
leon_str_image.i_imagetype = 0
leon_str_image.i_quality = 9
leon_image.of_createimagewithoptions( ls_filepath, ls_newfile, leon_str_image, leon_str_info )

p_photo1.picturename = ls_newfile

destroy leon_camera
destroy leon_image

MY INSTANCE VARIABLES FOR THE WINDOW WITH THE BUTTON IN

eon_mobile_cameraex leon_camera
eon_mobile_str_cameraoption lstr_option
eon_mobile_imageex leon_image
eon_mobile_str_imageoption leon_str_image
eon_mobile_str_imageinfo leon_str_info
