General Discussion / Pdf editable

Hola, lo primero felicitarte y darte las gracias por este software, es increíble, enhorabuena! . Actualmente uso el pdf que genero en tu web con la tablet, pero los pdf's los trata como imágenes y no permite la búsqueda de caracteres que sería muy útil al coser por colores. ¿Es posible estudiar si se podrían hacer así?  He probado con algún pdf comprado (desconozco que software usan) y el pdf te deja buscar los símbolos, facilita mucho la labor. 

General Discussion / Re: How many strands of floss do I use?
« Last post by kayjaybee on September 05, 2016, 12:30:23 PM »
For me I base the strands on what count fabric I am stitching on. Generally for under 25 count I use two strands and for 25 and above one strand. Hope that helps!

I just got my first pattern and just have a few questions. I have been doing cross stich for over 20 years and just started to do the portraits but am hooked already. Being able to get the patterns for free is a dream come true. I did notice there are no arrows pointing to the middle which is where everyone starts. Maybe someone could tell me how to find the middle. Also, it doesn't say how many strands of floss. I always use 2 strands so I guess I will go with that unless I hear otherwise. Thanks in advance for any help on this matter.  ;D

Hello - this is a phenomenal free service and I love that there's a forum. In looking at the color list on the last page of the pattern, does the number refer to the number of skeins I need to use of each color? I can't seem to find how many strands of floss I should use of each color. Thanks for the help!! 
General Discussion / Colors updated for Lecien Cosmo Floss
« Last post by lammert on August 12, 2016, 07:57:01 AM »
A few days ago I received the official digital color image set of all the Cosmo Floss colors produced by Lecien. This cotton floss is mainly sold on the Japanese market but is also available at some stores in other countries. I have updated the Cosmo color database based on the data received from Lecien. Because of this the generated patterns should better match the real colors of the floss. There may however be a slight difference between old and new generated patterns due to this.

Please note that for all floss brands available in Pic2Pat, brand specific floss to color matching tables are used. Due to this, matching between the floss colors and picture should be as accurate as possible for each individual floss brand. But due the the relatively small numbers of colors per brand (between 400 and 500) and the algorithmic interpretation taking place when matching the colors, unavoidable differences will occur between the original pictures and the generated pattern.

Thanks so much for this question, it is probably the question I have received most in the last years.

With such a large user base, a significant amount of people lose one or more pages of their pattern during the stitching process, either due to a computer crash, spilling coffee on it or the dog eating some pages. I therefore would like to create an option for users to retrieve their previously created patterns. But I haven't created such an option yet due to a few reasons.

First of all there is a technical and financial reason. With an estimated size of 2 megabytes per generated PDF file and 2.8 million patterns generated in total, I would need 6 terabyte storage just to store the patterns. Reliable storage on the internet including backups with this size would cost around $1000 per year.

The second reason is privacy. Currently all uploaded and generated data to create a pattern is erased from the server after a maximum of six hours. Many patterns contain personal information like pictures of people and private areas, and with this policy I can guarantee that no private information will remain on the server. If patterns would be archived on the server, I would have to take measures to protect that private information, by authentication, encryption or probably both.

Authentication would mean that people have to identify themselves before using the service and generating a pattern. Otherwise I will not be able to match a user with their own patterns later on. This would increase the barrier to use the system significantly. Pic2Pat has been designed to be used by people with practically no experience in using computers or websites. When designing the system my main test user was my then 73 year old mother who liked cross stitching but only had limited computer skills. Only when I was confident she could use the system without difficulties, I released it on the Internet. Having an authentication wall with registration, password selection etc would have made it too difficult for her and for many other users.

So the only way I can guarantee privacy and use authentication to retrieve lost patterns is by providing a unique authentication key AFTER the pattern is generated. Besides the current sequence number P2P-2345678 there could be another code printed on the pattern which is used as a password to logon to the system to retrieve a duplicate of that pattern. That is technically possible although one should have at least one page of the pattern with the key to retrieve the copy.

Lets assume that I'll manage to store the PDF files in a secure way, and that each PDF file has a unique authentication key which is printed on each page. Then I'll have still two problems left.

The first problem is that some users want to share one or more pages of a pattern on the internet to show others their stitching projects. If they just publish one page (for example the front page with the image) and the authentication key is readable on it, then anyone on the internet can download that full pattern. That may not be desirable because the user may not have had the intention to distribute their work freely and just wanted to show one page.

The second problem is that if the pattern contains copyrighted work not owned by the user who generated the pattern and the pattern can be distributed from my server through a "retrieve old patterns" option, there may be liability issues regarding the intellectual property rights. The copyright owner can in principle sue me for distributing copyrighted work. To tighten that hole, all patterns must be encrypted individually with a key only known by the owner. In that way I can guarantee that I couldn't have known if the content of a pattern was copyrighted. I must also have procedures in place to reply in a timely matter to copyright infringement notices. And last but not least, a Terms of Service on the site should be in place which complies to the copyright laws of the 150+ countries the users are coming from.

So hopefully you can see there are some challenges before I can add an option to the website which allows the retrieval of old patterns, the financial part currently being the biggest hurdle. Providing a free service doesn't make it easy to generate a constant $100 per month to store patterns for future pattern retrieval. The only option I can think of is to have a "pay per restore action" option which let people only pay if they want to retrieve an old copy of their pattern. General users would then still be able to use the service free of charge.

If you have any alternative ideas how to implement a pattern backup service which tackles the issues mentioned above, just drop them here and I will be happy to discuss them.

Is it possible to get patterns that were previously created?  I created a pattern from a picture and the file was saved on my computer.  My hard drive crashed and I lost a lot of things.  I did not have the pattern backed up anywhere and would really like to have it.  I tried uploading the picture a second time, but being a different computer, I guess it read the picture slightly differently and the new pattern does not match exactly.  I have the number that was on the original pattern.

Thanks so much for your explanation! I will now start stitching and upload a picture of the result when it is finished.

Thanks for your interest in using Pic2Pat Ashley!

Page numbering of the pattern pages in the PDF file may at first not seem obvious, but it is not really difficult to sort the pages. Page number one is always in the left bottom corner. You can see on each page small numbers at the left and top of the pattern. These numbers are counting 1,11,21,31, etc. You can use these numbers to put the other pages in place. Page two will probably be at the right side of page one, and page three next to page two. With 15 pages in total you will probably either have a pattern with 3x5, or with 5x3 pages. Therefore page 4 and 5 will either be at the right side of page 3, or at the top of page 1 and 2. Use the small numbers at the side of each pattern page to guide you.

Hope this helps you. If you still are not able to determine the page sequence you can upload the PDF file here to the forum and I will be happy to help you out.

Happy stitching!

Hi all,

First I want to thank you for such a great website. I am a newbie creating patterns with pic2pat and I just printed a pattern with 15 pages. But now I am confused where to start.  :-[ The pages are numbered 1 to 15, but which one should be at the top? Any help is greatly appreciated.
