inkjet | image decoding , encoding & EXIF reading library | Computer Vision library

I am using ghostscript's tiffsep1 device as a RIP for an inkjet system and want to limit the amount of ink applied per dot. I got the impression that the inklimits from ICC profiles only work on the coarser DitherPPI resolution but not the the DPI. Is there a way to limit on this resolution as well?

For more clarity, see these two images of a (0.75, 0.5, 0, 0) CMYK colored area:

Cyan: Magenta:

Clearly the upper left pixel is set in both channels, giving 200% ink. If I wanted to limit it to 100%. Even when I give it a "global" inklimit of 100% by scaling down to (0.6, 0.4, 0, 0) CMYK we get this:

Cyan: Magenta:

so still enough overlapping area where 200% ink would be reached pixelwise.

Is there some setting in ghostscript to avoid this?

PS: I am aware that the situation is worse here because all channels use the same angle and frequency so the cell centers will aways overlap. However, even with default angles we would eventually get some pixelwise overlap in some places which is what I want to avoid.

On a web-page with many b tags with the same class names I want to extract the text between 2 different closed html 'b' tags specifically these b tags

I am working on a project, that needs to scan for public Wi-Fi access points.

Currently, I am filtering the ScanResult like this:

My Page is located here - http://hoffwebsites.com/mcwp-2/buy-by-industry/printing/

Basically, I want to link directly to my tabbed content.

Where it says: UV-cure inkjet, Inkjet, Aqueous Inkjet, Digital on Demand, Screen Process, Flexography, Gravure, Offset Lithography, Thermal Transfer, Laser Printing

I want to provide a link to a user that will take them to this page but with a specific tab open, not the "UV-cure inkjet" by default. So if I want someone to see the "Thermal Transfer" tab open as soon as they get to this page, I need to be able to link to that tab directly but I can't figure it out.

Those links have classes & data-tab, example:

I am officially lost.. I have a trivial piece of python which checks whether a file exists. The path is stored in a dictionary.

When I execute next line of code, it returns false:

I have implemented a network with d3.js in javascript and I would like to change a color of a link from grey to red according to a json received. The JSON shows the source and the target node that will be connected. The schema of the nodes architecture is the one below:

Now, when the JSON is received, I parse the data and I append a new line connecting the source and the target node to red with the code below:

I'm sorting out how to achieve the following, I want to use smart or memory cards in a project. The cards should be read by standardized card readers (for example ACR38). When they are read by the computer ( command line or by a software (processing or p5js or similar), there should be a popup a window which shows the contents of the card being a picture and a text. Bit similar when I use my regular ID to be read by my E-idsoftware.

For the moment the card I have is this one SLE4428 (at the bottom instructions from the vendor) These have no data on it yet and are bought blank

=> datasheet

The software I found but don't know if it's suited for my project and how to specifically use it is the following.

Opensource tools that I found when searching for SC cards software (no id how to use them.)

https://linux.die.net/man/1/opensc-tool

https://linux.die.net/man/1/opensc-explorer

I looked at my smartcard reader and found that http://www.acr38u.com/ is a platform but has to be payed for and I'm unable to found sofware for this on linux or apple. Again here I found a datasheet with hex code to connect to the card, but still not how to physically connect to the cards.

This site shows many points of a working shell but I can't find the installer for it. opendsc

Then lastly this is the most promising and I already contacted the maker of it. But installation gets stuck in the make process (which I've already searched for and is not solution yet, being at it for a week now so therefore this post, maybe the community can help with an alternative look)

This is the explanation from the vendor side (Aliexpress) which is kind of specific. Though I don't know where to input these hex codes to write or read from the card. (there is a software but it's windows (If there is somebody that can say, that the way to solve the core question of my project then I'll try to get a windows pc to work on it via that way))

Let's say a there is a shop that sells two kinds of products, computer components and peripherals. Components category includes:

• Mobo - gpu type(amd/intel), num. of SATA ports(4/6/8) ...
• CPU - Frequency(3, 3.6, 4 GHz), num. of cores(2/4/6/8), onboard graphics(yes or no)...
• RAM - type(DDR2, DDR3, DDR4), memory (2/4/8 GB), frequenct (1600, 2666, 4600 MHz)
• GPU - chipset(AMD/nVidia), memory(2/4/6 GB)
• Storage - type(HDD/SSD), dimensions(1.8, 2.5, 3.5 inch), capacity(256/500/...)
• Monitor - type(LCD/LED), dimensions, resolution, ports(Display Port/HDMI/DVI
• Mouse - technology(laser/optical), connectivity(wireless or wired)
• Keyboard - Connectivity(wireless or wired)
• Printer - technology(laser/inkjet), kind of printing(black and white or coloured)

All products though have some common features like : model, year, manufacturer and price.

The kind of product matters because if a product is a component, the client get 25% discount and if it is a peripheral the client gets 10% discount, so that is important for what i need to implement afterwards.

Basically, my question is: How to organise all these into classes? I guess i need to create a class called Product(Top of the hierarchy) with instance variables: model, year, manufacturer, price. Then a Mobo class with instaces: gpu type, num. of SATA ports... a CPU class with instance variables: Frequency, num of cores .... etc. Should i create two more classes, Components and Peripherals? What instance variables will they include?

Newbie here with weird error. Before I start - I've read and understood (at least I think so) this topic: How to fix "Headers already sent" error in PHP which has great overview of this error, but I did not find solution there. Now the problem: I have 2 simple .php files (05.php and 10.php)... both of them contain 5 table rows. First 3 columns are not relevant (simple text). Fourth column reads content of .txt file and displays it. Fifth column has 2 submit buttons("+" and "-") which basicly open .txt file, read number in it, changes it's value, replace value in file with changed one and refreshes site. I need to include both of those files in my "main.php" file.

When I open them separetly, they work fine, when I include any of them in "main.php", everything works fine, but when I include both of them, input buttons on firt 7 rows work fine, but buttons on rows 8-10 give me this error:

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\test\10.php:94) in C:\xampp\htdocs\test\10.php on line 120

Second line number changes when I press different input buttons (which is obvious). First line number is always the same, and points to line with this code :
