You will need to use a larger image size for images like that, there is only so much you can wish for....

53

I reduced it to 400 pixels as you told me, before the image was like this:

Sorry how can I use webviewer with resize extension Taiufun?
ThanksResize.aia (894.0 KB) webviewer.aia (1.2 MB)

55

Sorry, that is an over-complicated solution....

  1. Download the image and save to Application Specific Directory (ASD)
    1.5 resize the image with the extension if you want to (but you can do this in 2. with html)
  2. Have a suitable html file with an img tag to show the image in the ASD
  3. Show the html file in the webviewer

If you have complex images with text and "graphics" you are better off just displaying as I have indicated above in previous posts and scroll/resize in the webviewer window.

You can save the image to file and load into an html file to achieve much the same thing.

There may be other ways.....

Same idea but it contains huge letters which takes lots of time to load

I have made you a Canvas Image Viewer which should do what you want.

CanvasImageViewerFinal.aia (8.3 KB)
Possible issues with this version see here:

Process:

  1. Load an Image from the list (works with images on sdcard as well as google drive files)
  2. Some javascript in the html page gets the aspect ratio of the image
  3. Sets the image to an imagesprite on the canvas
  4. You can move the image around (drag on image)
  5. Resize the image using the slider

note: I couldn't get the canvas any bigger than 1792 x 1792 without the app crashing. Tested on Android 10/11

Here hopefully a version that will work on most phones, canvas sized to 1280x1280, just means you cannot enlarge as much as you may like.

Great work Tim - above and beyond. :sunglasses:

59

Sorry TIM but I can't try your AIA file because it crashes both from Companion and from installed on the Smarphone, I don't understand why

60

Try reducing the size of the canvas to 1000px height and width

61

But in the first block at the top "imgList" do I have to link my images to the Drive or can I use your images to test?

62

Please use my images

63

I can not try because from the computer in Al Companion after reading the QR with the Smartphone it crashes and therefore I can not try it

64

I tried several times but nothing ...

You are using App Inventor version nb186 online via either Google Chrome or FireFox?

Try reducing the canvas size to 300x300. it seems this may be causing the problem?
(this will reduce the main feature of the app, but should get it working....)

72

Sorry to be a pain Michele - what is the Manufacturer, Model and Android version of your Device?

74

Ok Tim I reduced Canvas 300x300 now it doesn't crash but when I press the LOAD IMAGE button I don't see any image I don't understand

75

We identified a bug along the way which MIT have just confirmed. You can keep trying to increase your canvas size bit by bit. As 1792 x 1792 didn't work, try 1500 x 1500. If that doesn't work try 1200 x 1200.

When you press Load Image the image should still appear in the centre of the canvas, it is just the resizing that will be affected.

76

YES ok 1500x1500 is ok but when I press on LOAD IMAGE nothing with null load
