I'm using a XamNumericEditor control and I would like to display the value 0.000 as default. When I click on the spin button it should increment by 0.005 points. It should also support negative numbers. The maximum limit should be 100.000. Kindly let me know what would be the format and mask for this scenario.
Also, kindly point me to a link where I can learn about using the right mask and format.
Thanks.
I guess I found out this.
I don't require the format property. Mask is -nn.nnn and Value is set to 0.000 by default and spinincrement is set to .005
Thanks

I am new to Google Earth Engine and have started playing with mathematically combining different bands to define new index. The problem I am having is the visualisation of the new index - I need to define the max and min parameter when adding it to the map, and I am having troubles understanding what these two end points should be. So here come my two questions:
Is it possible to get the matrix of my image in terms of pixel values? Then I could easily see from what values they range and hence could define min and max!
What values are taken in different bands? Is it from 0 to 1 and measures intensity at given wavelength, or is it something else?
Any help would be much appreciated, many thanks in advance!

If this is what you want to do, there's a built in way to do it. Go to the layer list, click on the gear for the layer, and in the “Range” section, pick one of the “Stretch:” options from the menu, then click “Apply”. You can choose a range in standard deviations, or 100% (min and max).
You can then use the “Import” button to save these parameters as a value you can use in your script.
(All of this applies to the region of the image that's currently visible on screen — not the entire image.)

This is entirely up to the individual dataset you are using; Earth Engine only knows about numbers stored in bands and not units of measure or spectra. There may be sufficient information in the dataset's description in the data catalog, or you may need to consult the original provider's documentation.
The scrollbar in my application is just taking 2 positions and nothing in between, that make it look silly to be honest... is there a way to raise its precision?
First position
Second position
Have a look at https://doc.qt.io/archives/qt-4.8/qabstractitemview.html#horizontalScrollMode-prop There you can set QAbstractItemView::ScrollPerPixel
The answer of V.K. is correct, I just want to give you the link to the current release document for Qt 5 to setHorizontalScrollMode and use as parameter QAbstractItemView::ScrollPerPixel
I am trying to determine if, using just CSS, there is there a way to format floating point numbers to a specific number of digits to the right of the decimal point?
The reason I want to do this is that I need to use a website that displays a massive amount of continually updating data in tables. (Because the data is continually updating, I can't just export the data into a spreadsheet.)
The values are floating point and range from 0 to 9999. The number of fractional digits varies from 0 to 7. For the most part, I have no use for anything beyond hundredths (2 places to the right of the decimal point). The exception is for values ranging from 0 to 9, but I'm willing to forego that case, if necessary.
This is an tiny example of how the data is currently displayed:
9484.83
133.57643
1344.5432
9.5848274
58.48381
5989.1
1.5847493
1.348
As you can see, it's hard to read the data with that presentation. Ideally, I would like to use a CSS overlay to reformat that data as:
9484.83
133.57
1344.54
9.584
58.48
5989.10
1.584
1.348
If that's not possible, I'm fine with:
9484.83
133.57
1344.54
9.58
58.48
5989.10
1.58
1.34
Using CSS, I can easily enforce a maximum width for the HTML elements displaying the values. I can use em units to try to not get any digits partially displayed (not 100% effective though, unless forcing a monospaced font, which results in much less visible data in the viewport). But even using such techniques, I still wind up with values displayed as 58.4848.
Can CSS be used to solve this task?
I've been looking at this page, as well as this code example and I've noticed that the x_advance, y_advance, x_offset and y_offset fields in hb_glyph_position_t are of the type hb_position_t, which is an alias to int32_t. I haven't found any documentation about which units are used for these fields. The examples above suggest that they're 64ths of something, but that's all I can infer.
Does anyone else know the exact unit implied by hb_position_t?
It is in input font size units (say pixels).
The idea there is you multiply the input font size by 64 then you divide the position by 64 after the shaping so you will be in control of how much sub pixel precision you need.
I'll make some indefinite animations inside my A-frame web application. My animation must play infinity and must have a yo-yo effect. Form an opacity of 0.25 to 0.75 an back each in 3000 millisecondes. For this I use next code:
let box = document.createElement('a-box');
box.setAttribute('src', '#outer');
box.setAttribute('position', '0 0 -5');
box.setAttribute('color', 'red');
let anim = document.createElement('a-animation');
anim.setAttribute('attribute', 'opacity');
anim.setAttribute('from', '0.25');
anim.setAttribute('to', '0.75');
anim.setAttribute('fill', 'both');
anim.setAttribute('repeat', 'indefinite');
anim.setAttribute('dur', '3000');
anim.setAttribute('direction', 'alternate');
box.appendChild(anim);
document.getElementsByTagName('a-scene')[0].appendChild(box);
<script src="https://aframe.io/releases/0.5.0/aframe.min.js"></script>
<a-scene></a-scene>
Like you can see this is not working. It goes from 0.25 to 0.75 in 3000 millisecondes and instantly back to 0.25 to repeat again. In the documentation of A-frame stand this:
When we define an alternating direction, the animation will go back and forth between the from and to values like a yo-yo. Alternating directions only take affect when we repeat the animation.
If I use an number (example the number x) instead of indefinite, the yo-yo effect works great but stops when it's x-times repeated.
What could I do for fix this issue?
i think it's fixed by throwing out the fill attribute
anim.setAttribute('fill', 'both');
Its supposed to handle the animation when its not playing, i guess when the replay is indefinite, its playing all the time and either tween.js or three.js don't like it.

I tried setting it to 'none' or whatever, but i only got it working while thrown out.
