Load image in browse (base64)

[agustinh2000]

Hi!

I have string that I receive from the device (image base64 Camera.DestinationType.DATA_URL), When I want to see it directly in the browse (image field type) the string is broken ...
for example

data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD....(in field)

data:image/jpeg%3Bbase64%2C/9j/4AAQSkZJRgABAQAAAQABAAD...(
inspect element in web browser)..

Any idea how to solve it? (stringtheory, etc.)

thanks!

Maybe StringTheory: http://www.capesoft.com/docs/StringTheory/StringTheory.htm#stUrlDecode

>> data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD

so the clues are here, ys. It's an image, encoded as base 64.
So you need to get the "data" part (I'm guessing it's everything after the comma) then Base64Decode it (using StringTheory) and you have the "raw jpeg" image.

The easiest way to serve it is to give it a name, same it to disk (somewhere under the web folder) and then use that name in an image control on the form.

Something like that..


str.SetValue(clip("data" part))
if str.Length()
  str.Base64Decode()

end

[Bruce]

something like;

str.SetValue(clip("data part"))
str.SetValue(str.after(','))
str.base64Decode()
str.SaveFile('whatever.jpg')

It works perfect, thank you very much!
