QUESTION
In CameraX Analysis, setTargetResolution(new Size(2560, 800), but in Analyzer imageProxy.getImage.getWidth=1280 and getHeight=400, and YUVToByte(imageProxy.getImage).length()=768000。In Camera, parameter.setPreviewSize(2560, 800) then byte[].length in onPreviewFrame is 3072000(equales 768000*(2560/1280)*(800/400))。How can I make CameraX Analyzer imageProxy.getImage.getWidth and getHeight = 2560 and 800, and YUVToByte(ImageProxy.getImage).length()=3072000? In CameraX onPreviewFrame(), res always = null, in Camera onPreviewFrame(), res can get currect value, what's the different between CameraX and Camera? And what should I do in CameraX?

Answered 2021-Jun-13 at 01:15With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution()
states that:
The maximum available resolution that could be selected for an ImageAnalysis is limited to be under 1080p.
So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis
resolution that has the same aspect ratio you requested (2560/800 = 1280/400).

QUESTION
We have a CLOB column, in a DB2 database that contains XML. The query does not seem to like the embedded xmlns. I simplified the query down to this:
values xmlquery('$rf/Producers/FIRMS/FIRM/EIN/text()' passing xmlparse(document '27/') as "rf")
If I remove the xmlns embedded in Producers, it works. As is, it does not return anything, but does not throw an error. Like I said, this is simplified for troubleshooting. In reality, the document would be from a CLOB column in our DB. All th XML stored in the CLOBs contains the xmlns. Any suggestions on how to deal with this?

QUESTION
I have a Vuetify data table that is refreshed from the server every 5 seconds. It has selectable rows. If you select a row, then something in the data changes, the v-model array of selected items does not reflect the changes inside the row items. This codepen is a slightly modified version of a Vuetify example:
https://codepen.io/hobbeschild/pen/bGqGMQQ?editors=1010
Select the first row. At the top you will see the time in the selected item. Wait 5 seconds for the data to refresh. You will see that the selected item time does not match the row item time anymore.
Is there a way to ensure the v-model array contents reflect the new values in the items? I can think of a way to do this programmatically, but I have lots of tables like this and hope there is an easier way, with the table props perhaps.
HTML:
...ANSWER
Answered 2021-May-10 at 16:00I do not think there is any "build-in" way to do what you want. Problem is model (selected
in your code) holds references of selected objects from items
/deserts
array. If you replace items
/deserts
(with this.desserts = data.items
) with completely new array containing completely new objects, this is what you get...
So doing this yourself is most certainly only way. Either:
- Recreate
selected
whenever you replaceitems
/deserts
QUESTION
Question: Can we change the height of the title bar displayed in MahApps.Metro?
Details: For instance, in the following XAML example from the MahApps team, I want to display the content Deploy CupCake
- of the TextBlock
- below the image of the CupCake. So I removed the Orientation="Horizontal"
from the StackPanel
in the following XAML. As shown in the snapshot below, the content Deploy CupCake
is now showing below the image of CupCake - but it is hiding almost all of it. How can we make this content show all of it below the CupCake image?
Snapshot of the Toolbar with MahApps.Metro: Only about 10% of the content is showing below the image.
...ANSWER
Answered 2021-Apr-22 at 06:54First of all, it is better to use a to use a panel that distributes the available space among its content, like a Grid
, to prevent cutting off content as with the StackPanel
. Here, the data template defines a Grid
with two rows, where the TextBlock
scales to its desired size and the icon takes up the remaining available space. Also note the HorizontalAlignment
of the icon, it is centered.

I'm creating an interface with the ipyvuetify for a python workflow. At some point I need to change items dynamically in a DataTable but I cannot manage to make it change.
I created this small use case to show the bug. LEts assume that we want to create a new class that is inheriting from v.DataTable. this datatable will have 3 based items. in the top slot I'll add a btn, and when the btn is click, one element is added to the items list :

Answered 2021-Apr-07 at 10:06For Jupyter Widgets, you have to redefine the .items. If you append to the items list, the widget can't see that the mutable list has been edited. So below is basically the same solution you suggested outside of your class

Answered 2021-Mar-29 at 06:54You have done a very good try, but the behaviour is little different here
The mobile breakpoint scope is within the table and it doen't mutate the device type in this.$vuetify.breakpoint, so when you check this.$vuetify.breakpoint.xsOnly it will return true only if the screen width is less than 600 and not 10000 even if you want to confirm the same , you can put this.$vuetify.breakpoint.name inside a span tag in UI, you will get xs only if the screen width is less than 600
If you want to hide the sort_by if the device width is less than 10000, it is possible to manage by css
