dealing with canvas copy trouble in tcl



I created with Plotchart::createLogXYPlot in the canvas.
I'm drawing several Graph in same canvas. (Using several plot in same canvas)
I need this canvas to copy or convert file format type.
But I'm searching about this topic, didn't help for me.


Plotchart::createLogXYPlot



Main trouble is saved file having a clipping img.



Clipboard canvas is not working for me. (can't find tag about plotchart)



I'm trying these ways.



capturing canvas to img file format (clipping trouble)

Snapshot canvas (clipping trouble and spend many time)

Clipboard canvas (didn't work)



https://www.tcl.tk/man/tcl/TkCmd/clipboard.htm



Plotchart using Saveplot (need gs(gost scripts), I will not use it, Saved .ps file is success)



How to save Plotchart canvas other than PostScript without displaying it?



I think, fixing img clipping trouble is easiest way for me.



Canvas convert file format:

Using snapshot and convert file format:

Original graph:

@L. Alejandro M. Anything ok ( canvas copy, canvas to img File). And main problem is these ways are occured clipping problem. (error code is none) See above Sample img. #original graph is completed by my code.

If you want to save your canvas to image, may be this example help you:



package require Img
pack [canvas .c -height 50 -width 50]
.c create rectangle 0 0 25 25 -fill blue
.c create rectangle 25 25 50 50 -fill green
raise . ;# if there's anything over the window on-screen, it'll be obscured in the image
update idletasks
image create photo theCanvas -format window -data .c
theCanvas write "C:\your\path\here\example.png" -format png


package require Img
pack [canvas .c -height 50 -width 50]
.c create rectangle 0 0 25 25 -fill blue
.c create rectangle 25 25 50 50 -fill green
raise . ;# if there's anything over the window on-screen, it'll be obscured in the image
update idletasks
image create photo theCanvas -format window -data .c
theCanvas write "C:\your\path\here\example.png" -format png



(Note: the line of update isn't in the original)

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas...

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12...

Creating a leaderboard in HTML/JS

Image
Clash Royale CLAN TAG #URR8PPP Creating a leaderboard in HTML/JS I'm trying to create a top 10 leaderboard, for now, I've only implemented 3 players, but I'm coming across an issue. My script doesn't seem to be outputting anything on webpage. The purpose of the script is to compare 3 arrays, player1,player2,and player3 solely based off of score. Which is the 2nd index of each array. I want the script to list the players in order of highest score. This method doesn't really seem to be efficient, especially when I'll have to add 7 more players. Could someone suggest perhaps an easier approach, as well as show me why my script wont output the info. Here's the JS function leaderboard() { var player1 = name:"Thomas",date:"01/23/18",score:"201"; var player2 = name:"Michael",date:"03/24/17",score:"943"; var player3 = Name:"Lisa",date:"06/04/18",Score:"79"; if(player1[2]...
