[Question] How does the AssetManaget work?

[mantielero]

Could you explain how the asset manager work?

I am trying to show an image using the full path, but I am failing (unless I put the image in the res folder).

Regard Jose M.

Asset manager is used to retrieve assets from the app resources, which are different things depending on your platform (on windows and linux this is res folder). To load an image from an arbitrary file path use imageWithContentsOfFile. To load image from arbitrary URL (including http://, https://, file://) use loadImageFromURL

Thanks a lot. I managed to use imageWithContentsOfFile. I don't know why loadImageFromURL is not working for me. I am using similar code to your sample 3. Something like the following:

method init*(v: ImageSampleView, r: Rect) =
    procCall v.View.init(r)
    loadImageFromURL("file:///home/jose/src/pdf/Frances_01.pdf_FOLDER/original_thumbnails_256/68db24e7-fe4f-407b-89af-04bbbc7746f9-16.png") do(i: Image):
        v.httpImage = i
        v.setNeedsDisplay()

    #do(i: Image, err: string):
    v.image =  imageWithContentsOfFile("/home/jose/src/pdf/Frances_01.pdf_FOLDER/original_thumbnails_256/68db24e7-fe4f-407b-89af-04bbbc7746f9-16.png")
    v.setNeedsDisplay()

but b.httpImage is empty, and I don't know why.

Ah, turns out loadImageFromURL doesn't support file: scheme. PRs are welcome :)

EDIT: loadImageFromURL

The question is answered i suppose

[mantielero]

Yes it is. Thanks a lot mate.
