digitizeR | R package to extract data | Data Visualization library

I am having trouble with my digitizer and pen. The palmrejection detects the pen only when it's like 1cm above the screen.

So I'm trying to make a batch which disables or enables the touchscreen when executed.

I have a set of points x_i, y_i which represents not bijective mapping (there is no one to one correspondence. See the attached picture:

(Don't pay attention on the second line. It just shows a center mass). I am trying to find the first peak on it (as you can see it finds not correctly). The code is given below. Here I am sorting points by Ox axis, then using find_peaks function:

I am trying to use the webusb api to connect my USB device which basically is a digitizer. the usb version is 2.0. I have successed to request the device in chrome but failed to open the device with the error Access Deny. request device the usb device has 3 interface: 2 HID and 1 USB (winusb loaded). here is the information shown in xusb:

I have IIyama ProLite T2252MSC-B1 screen which has Projective Capacitive 10 point touch technology. It works like a charm under Windows 10. I was thinking the same will be on Raspberry Pi 4 running latest Raspbian and Chromium browser. But all I got was just single point like mouse emulation. Each time I touch the screen, mouse pointer is visible and moves to the direction when I touched the screen. Comparing to the responsiveness in Windows 10, Raspbian experience is terrible. Touches are not recognized precisely and instead single click sometimes it works like double click, sometimes as a long press (right click). Although in Chromium browser we have support for gestures (ex. Zoom in and out works ok, swipe left right also works ok) but touch (click) is nothing nowhere Windows 10 / mobile phone experience. I found that this screen is using Weida Hi-Tech digitizer. Maybe someone knows if there are some other 22 inch monitors that has same level of touch support/experience under Linux / Chromium that is offered in Windows / Chrome?

I'm using Firebird 3.0, and I'm trying to get a single record for a duplicated cost where Manufacturer, Model, Part type is the same

I'm working on a Qt5 application to attempt to make use of raw input data from a touchscreen because touch is not fully supported by my Linux kernel (2.6.32). I wrote a parser for the raw data coming from /dev/input/eventX because even though X doesn't support touch, the events are still there.

I'm able to read the events just fine, and wrote a wrapper called "TouchPoint" which contains the ID and (x,y) coordinates of each touch point, as well as a boolean indicating whether or not the touch point is currently "active" (ie: the user currently has that finger on the screen). It's worth noting that I also output the number of points of touch currently on the screen, and the value is accurate.

My issue is that I can't seem to figure out how to accurately simulate a mouse click with it. With multi-touch events in Linux, each touch point is assigned a "tracking ID" when the user presses a finger to the screen, and when that point is lifted, an event setting that slot's tracking ID to -1 is generated. I use this change of ID from some value to -1 to indicate that a touch point is "down" or not:

I am trying to read an array from an XML data file with the shown structure. By using How do I parse XML in Python? I received the following without my array.

I have a dictionary where key is model name and values are keywords. I want to filter every row in a column that string contains one of the keywords that are in the values of dictionary. Matching should be case insensitive.

Dictionary looks like this:

There are several packages available to digitize the line graphs e.g. GetData Graph Digitizer.
However, for digitzation of heat maps I could not find any packages or programs.

I want to digitize the heat map (images from png or jpg format) using Python. How to do it?
Do I need to write the entire code from scratch?
Or there are any packages available?
