QUESTION
I'm implementing a typescript function that takes a mono-argument-function and outputs a slightly modified version, where the argument is wrapped in an object.
I can't figure out how to keep track of original function's generics:
ANSWER
Answered 2022-Mar-06 at 15:44Typescript will not preserve generics through functions extracting the parameters and the return type using a conditional type.
If you use as type parameters the args and the return type, typescript will preserve the generics in the resulting function:

The ask: How do I get the viewing rectangle in the coordinates of a transformed and scaled node?
The code is attached below, it is based upon the code from this answer: JavaFX 8 Dynamic Node scaling
The details:
I have a simple pane, BigGridPane that contains a collection of squares, all 50x50.
I have it within this PanAndZoomPane construct that was lifted from the answer referenced above. I can not honestly say I fully understand the PanAndZoomPane implementation. For example, it's not clear to me why it needs a ScrollPane at all, but I have not delved in to trying without it.
The PanAndZoomPane lets me pan and zoom my BigGridPane. This works just dandy.
There are 4 Panes involved in this total construct, in this heirarchy: ScrollPane contains PanAndZoomPane which contains Group which contains BigGridPane.

QUESTION
In the documentation of Pillow (PIL Fork). One font type is mentioned in ImageDraw module tutorial that is "FreeMono", for example fnt = ImageFont.truetype("Pillow/Tests/fonts/FreeMono.ttf", 40).
It seems possible to get other fonts' ttf locally on the machine and use it with Pillow, but I was wondering are there any other testing fonts (other than "FreeMono") for testing and playing around with this tool, like some bolder fonts, etc?

QUESTION
So, I am building a little Python program to do some cost and throughput calculations for me. Keep in mind, I am a Python novice and completely new to PySimpleGUI with this project. I am specifically concerned with why, in the code below, line 59 (thruput_window['LISTBOX'].update(prompt) within the update_values() function) is causing the program to hang? I would think it should update with the indicated string, and continue on through the while loop, but instead it just stalls out, and doesn't even update the Listbox element with prompt. Any ideas?
Thanks for the help, and apologies for the long code block; I don't post on here often, and wasn't sure how much to include so I just posted the whole thing.
...ANSWER
Answered 2021-Dec-11 at 06:12update_values called in the event "Append" of thruput_window.
In function update_values, you do something wrong
- bind return key to element
'USER-INPUT', binding should be done right after your thruput_window finalized, then while loop to read event.
QUESTION
TL;DR: I want to create a standalone application that has image resources (with alpha channel) embedded. What is the modern/standard way of doing this and extracting the data?
I am currently writing an application in C++ that uses OpenGL as the graphics engine (I chose it for the faster development time compared to Vulkan, even though I really want to learn Vulkan as well) and in this app I use Signed Distance Fields to render my text. This requires a Font Atlas with an alpha channel to draw the characters from.
I want to be able to embed this Font Atlas (currently it is a .PNG file) in the executable. There are other image resources as well, but I am mentioning this scenario to show why I really need the alpha channel.

...ANSWER
Answered 2021-Sep-13 at 10:03The AddFontFile method expects the path of a physical file on disk. You cannot pass in a pack: URI, because it doesn't understand that format. And you cannot just call .ToString() on a Stream, since that won't produce any meaningful information.
You need to extract your font file to a temporary file, and pass the path to that file to the AddFontFile method.
QUESTION
I need to create a GUI that let you type phrase and try to autocomplete each word that it is typed and print the input again under it. When I use the QCompleter from PyQt5, when I type one word it works fine, but as soon as I type the second one I can't autocomplete it because it tries to autocomplete the whole input phrase. How can I give a suggestion for each typed word?
...ANSWER
Answered 2021-Sep-03 at 08:41Since you are going to add a text, then setting the QCompleter to the QLineEdit will complicate the task, in this case it is to handle the logic of the QCompleter independently.
QUESTION
I have multiple k8s cluster in private network which I can access only through a jumpbox/bastion host.
For example below are my k8s clusters:
k8s-c3 with endpoint ip 192.168.220.3
k8s-c4 with endpoint ip 192.168.220.4
k8s-c5 with endpoint ip 192.168.220.5
What I have been able to do is:
Create a ssh tunnel to 1 endpoint at a time eg: ssh -i /root/.ssh/id_rsa -4 -fNT -L 6443:192.168.220.3:6443 user@1.2.3.4 and use kubectl command from my local machine.
What I want to do is: Create a ssh tunnel to my bastion host for port 6443 for all the 3 destinations mentioned above and use kubectl config use-context to switch and connect to different clusters from my local machine.
Is this possible? If so how? If not possible using ssh what other alternatives do I have? Would really appreciate sample code example.
Thanks
...ANSWER
Answered 2021-Aug-24 at 06:10The ssh tunnel allows to open more than one tunnel in the same command, to multiple machines. The gotcha here is that you would have to use different ports, and change in the kubectl config file the ports you are tunneling.
The command would have multiple -L:
QUESTION
I am using a 3.5: TFT LCD display with an Arduino Uno and the library from the manufacturer, the KeDei TFT library. The library came with a bitmap font table that is huge for the small amount of memory of an Arduino Uno so I've been looking for alternatives.
What I am running into is that there doesn't seem to be a standard representation and some of the bitmap font tables I've found work fine and others display as strange doodles and marks or they display upside down or they display with letters flipped. After writing a simple application to display some of the characters, I finally realized that different bitmaps use different character orientations.
My questionWhat are the rules or standards or expected representations for the bit data for bitmap fonts? Why do there seem to be several different text character orientations used with bitmap fonts?
Thoughts about the questionAre these due to different target devices such as a Windows display driver or a Linux display driver versus a bare metal Arduino TFT LCD display driver?
What is the criteria used to determine a particular bitmap font representation as a series of unsigned char values? Are different types of raster devices such as a TFT LCD display and its controller have a different sequence of bits when drawing on the display surface by setting pixel colors?
What other possible bitmap font representations requiring a transformation which my version of the library currently doesn't offer, are there?
Is there some method other than the approach I'm using to determine what transformation is needed? I currently plug the bitmap font table into a test program and print out a set of characters to see how it looks and then fine tune the transformation by testing with the Arduino and the TFT LCD screen.
My experience thus farThe KeDei TFT library came with an a bitmap font table that was defined as
...ANSWER
Answered 2021-Jun-12 at 16:19Raster or bitmap fonts are represented in a number of different ways and there are bitmap font file standards that have been developed for both Linux and Windows. However raw data representation of bitmap fonts in programming language source code seems to vary depending on:
- the memory architecture of the target computer,
- the architecture and communication pathways to the display controller,
- character glyph height and width in pixels and
- the amount of memory for bitmap storage and what measures are taken to make that as small as possible.
A brief overview of bitmap fonts
A generic bitmap is a block of data in which individual bits are used to indicate a state of either on or off. One use of a bitmap is to store image data. Character glyphs can be created and stored as a collection of images, one for each character in the character set, so using a bitmap to encode and store each character image is a natural fit.
Bitmap fonts are bitmaps used to indicate how to display or print characters by turning on or off pixels or printing or not printing dots on a page. See Wikipedia Bitmap fonts
A bitmap font is one that stores each glyph as an array of pixels (that is, a bitmap). It is less commonly known as a raster font or a pixel font. Bitmap fonts are simply collections of raster images of glyphs. For each variant of the font, there is a complete set of glyph images, with each set containing an image for each character. For example, if a font has three sizes, and any combination of bold and italic, then there must be 12 complete sets of images.
A brief history of using bitmap fonts
The earliest user interface terminals such as teletype terminals used dot matrix printer mechanisms to print on rolls of paper. With the development of Cathode Ray Tube terminals bitmap fonts were readily transferable to that technology as dots of luminescence turned on and off by a scanning electron gun.
Earliest bitmap fonts were of a fixed height and width with the bitmap acting as a kind of stamp or pattern to print characters on the output medium, paper or display tube, with a fixed line height and a fixed line width such as the 80 columns and 24 lines of the DEC VT-100 terminal.
With increasing processing power, a more sophisticated typographical approach became available with vector fonts used to improve displayed text quality and provide improved scaling while also reducing memory required to describe the character glyphs.
In addition, while a matrix of dots or pixels worked fairly well for languages such as English, written languages with complex glyph forms were poorly served by bitmap fonts.
Representation of bitmap fonts in source code
There are a number of bitmap font file formats which provide a way to represent a bitmap font in a device independent description. For an example see Wikipedia topic - Glyph Bitmap Distribution Format
The Glyph Bitmap Distribution Format (BDF) by Adobe is a file format for storing bitmap fonts. The content takes the form of a text file intended to be human- and computer-readable. BDF is typically used in Unix X Window environments. It has largely been replaced by the PCF font format which is somewhat more efficient, and by scalable fonts such as OpenType and TrueType fonts.
Other bitmap standards such as XBM, Wikipedia topic - X BitMap, or XPM, Wikipedia topic - X PixMap, are source code components that describe bitmaps however many of these are not meant for bitmap fonts specifically but rather other graphical images such as icons, cursors, etc.
As bitmap fonts are an older format many times bitmap fonts are wrapped within another font standard such as TrueType in order to be compatible with the standard font subsystems of modern operating systems such as Linux and Windows.
However embedded systems that are running on the bare metal or using an RTOS will normally need the raw bitmap character image data in the form similar to the XBM format. See Encyclopedia of Graphics File Formats which has this example:
Following is an example of a 16x16 bitmap stored using both its X10 and X11 variations. Note that each array contains exactly the same data, but is stored using different data word types:
