Hi Everyone, I am Sameera Gunarathne who is a participant for GSoC ’15 for FossAsia under fashion and technology. I am developing web based GUI for knitting applications. Today I am going to talk about importance of integrating a pattern editor inside knitting applications and little bit about my work on the pattern editor implementation.
Why knitting application should have a pattern editor? It’s to simply give the user capability of doing all the editing work on the pattern before it is sent for knitting. Therefore user will be able to proceed the whole knitting process using one application. User doesn’t have to use a separate application to edit the pattern and then import the pattern to the knitting software to get knitting done. Also most these pattern editor applications are commercially available which means user has to pay for the application and its updates. So that’s extra money. Some examples for available pattern editor softwares are knitbird , envisioknit , stitchmastery etc.
So what about open source knitting machine software with a feature rich pattern editor? Cool right. I am working on integrating feature rich pattern editor for the knitting web application that I am developing for FossAsia this GSoC. Following features are already added to the pattern editor implementation.
Getting a loaded pattern to a pixelated grid to give user a easily editable interface.
Pixelated pattern can be generated from available yarn colours that used for knitting.
Cropping tool for load necessary parts from the pattern.
Rectangular/Free Hand selection of loaded pattern.
Editing colour details of a selected area of the pattern.
Drawing tool for the loaded pattern. 
User is given capability to regenerate the pattern according to the available yarn colours for the knitting. This functionality allows user to understand how the actual knitting output will be there with the available yarn colours. Below are the some of screen shots of current implementation.
I am very much enthusiastic on the project and working hard to get a good outcome for the knitting web application implementation. See you with the next blog post update. Thanks :).
Hi everyone, I am Sameera Gunarathne and I am a computer science undergraduate of University of Moratuwa, Sri Lanka. This is the first time I have applied for the GSoC and FossAsia and I am quite excited to give my contribution to FashionTec as it’s a whole nice new experience that programming is applied with real world applications in fashion and technology paradigm. I have selected for developing a Graphical User Interface which runs as a web application which is intended to provide a common platform to give input for the knitting machine firmware.
As the first step I had to research on the existing knitting applications that are available online commercially and what they provide as features that still need to be included in open source knitting applications. I have looked into both knitting pattern design softwares and knitting machine embedded softwares including knitbird, EnvisioKnit ,Stoll knitting software, ShimaSeiki SDS One Knit. The most significant feature I have noticed is the feature rich pattern editor provided with the software. They provide features like loading patterns from different formats(jpeg, png,gif,pdf), transform patterns(crop,replicate etc) to create new patterns, drawing tools to create a pattern from scratch, Provide colour palette with available yarn carrier colours, Saving and loading the work done by the user in the application storage etc.
Therefore in this GSoC period I am developing the assigned Web User Interface with consisting of following components.
Web App FrontEnd
Work Space + Pattern Editor
Web App Back End
Web Client Server component(REST Api to communicate with knitlib interface)
Request Handler for back end logic
Knitting Simulator is used to simulate the knitting process through the user interface while the knitting is going on. It will display the carriage details, current knitting progress and a graphical simulation of the current knitting position of the pattern with row details. Project Manager component is to save knitting works as projects and load them later as the user preference.
This project consists of 4 milestones and under the first milestone I am working on the pattern editor features. Currently I have implemented loading different types of patterns into the workspace and pixelate them according to the number of rows and stitches allowed for the knitting. Following tasks will completed end of this week.
Identifying individual pixel in the grid as a stitch and add operations such as change colour, size etc.
Adding pattern editor tools for selecting pattern area, colour picker, crop-cut-paste tools for pattern replicating.
I hope this GSoC will be a fruitful one to spend with a successful implementation of the knit web app and looking forward to provide a competitive open source knitting software at the end of the development :).
Hello everyone, my name is Sebastian Oliva. I am a developer from Guatemala and part of the team of students currently in Google Summer of Code ’15 working on Fashiontec. During last year’s GSoC I built a GUI interface for the AYAB project, allowing for easier control for knitting machines supported by AYAB (Brother KH-930, KH-910).
Currently I am working on developing a knitting machine abstraction library and JSON based knitting file format that can enable the use of a single API to control a varied number of knitting machines. A knitting machine library allows us to create even more advanced software to control and operate machines, while a standardized and open format for knitting patterns allows us to create pattern collections such as the common pattern books usually shared by knitting communities, as well as enabling pattern editors and ecosystem.
Currently I am:
Working on designing and implementing Knitlib’s API design.
Writing tests for Knitlib’s desired behaviour.
Starting work on defining Knitpat, the open knitting file format.
I hope that this year’s GSoC brings a lot of advances to the machine knitting community, and I am happy to be a part of it.
