App background upload in low resolution

mOSkit · February 3, 2020, 1:10pm

Hi all
The background resolutions is greatly decreased when you upload the app to the device. I asked about it year ago but then i was told is just what it is. Any one know if this was fixed in the meantime or if there is a way to improve the quality of the background?
Thanks

Your previous post: https://groups.google.com/forum/#!msg/mitappinventortest/W1sH6faD7R0/Dl58D31xAAAJ

After testing this is still an issue. (Also if background image in arrangements)
Can’t find it raised in issues so will assign.

Great, hopefully this will be fixed as it seems to be an issue for many of us. Thank you

Are we going to receive some type of notification once this is solved or do we have to track it from time to time?
Thanks

Here is a possible way to improve image quality one developer uses to resolve a similar issue in a Canvas:

It may work for you. If not, be patient; MIT are aware of your previous comments. They have a small team with lots of issues to resolve. MIT recently fixed these issues:

Changes between nb182a and nb182b (February 18, 2020)

This is a bugfix component release. There is a new Companion, version 2.57b. Version 2.57a will continue to work, but without the fixes below.

[Bug] Restore HeightPercent for Slider
[Bug] Make ThumbColorActive visible for Switch
[Bug] Fix dictionary issues with String/FString mismatch

Other issues are in progress. When the issue you mention is resolved, there will be a notice on the Designer screen of recent improvements, bug fixes etc.

Regards,
Steve

Implement a Screen1 `AutoscaleImages` property

help wanted status: new feature request affects: ucr priority: low

**Describe the desired feature** Due to possible resource limitations of the …device, App Inventor has always scaled images down. This is done by computing a scaling factor in [MediaUtil](https://github.com/mit-cml/appinventor-sources/blob/b4bbaa77d1a958dd60881c672aa992a8523bef75/appinventor/components/src/com/google/appinventor/components/runtime/util/MediaUtil.java#L588). As devices have increased the amount of RAM available to apps, it seems reasonable to allow people to disable this "feature" in order to use high resolution images in their apps. I propose that we add a `AutoscaleImages` property to Screen1, defaulting to `true` for compatibility reasons, that developers can use to turn off scaling of images to take advantage of higher resolution displays. **Give an example of how this feature would be used** Anyone showing camera images, etc. could use this to show the full resolution image rather than a scaled version. **Why doesn't the current App Inventor system address this use case?** App Inventor gives no option to control this behavior, but people expect that if they provide a high res image it will show accordingly. Instead, it is scaled down and may become "fuzzy". **Why is this feature beneficial to App Inventor's educational mission?** While there isn't a direct benefit, students may appreciate having the ability to show higher quality images and not have their apps look "scaled down" compared to other apps.
