Create new document

[roro69]

Hello,
I would like to know if it is possible from a plugin to create a new document.

That's my problem: I create new documents but I have to calculate their area as follows:
 The height of the surface I desire is height 10 times
 The width of the surface I want is width / 2

 Example: My input data 624 * 22
What will give when I create new document
 Width 312 pixels
 Height 220 pixels

So what I wanted was to get my entry information; then create a new document with the good
dimensions

Thank you for your response, and thank you for your time

Hello
I'm sorry for the english approximatf; but I want to automate the dimensions of the canvas because I have to calculate them
each time with my input

Thank you for your answers and help provided

Effect type plugins cannot create new canvasses to work on. They are allowed to work on the active layer of the active image and that's it.

Hello, thank you for the response
If I understand correctly it is possible to create a blank bitmap in windows clipboard and load it in paint net
; so if that's the case, can you help me to code this solution?

Thank you for your answers and help provided

Greetings roro69,

You can create blank templates within Paint.NET. I have a folder on my desktop called Paint.NET templates.
When I need one; I simply look within the folder for the desired template and right-click on the template and then select

'Open with' and then select Paint.NET. If the template is saved as a PDN file, just double-click on its icon and it will

automatically launch into Paint.NET.

Good evening
I tried with the code below but I do not understand the software tells me type
unrecognized image

 Dim painte As String = "C:\Program Files\paint.net\PaintDotNet.exe"
        Dim s As String = System.IO.Path.GetTempFileName()
        Dim monimage As Bitmap = New Bitmap(200, 200)

        monimage.Save(s, Imaging.ImageFormat.Png)

        Dim p As Process = Process.Start(painte, s)
        'maybe here's a better way to wait
        While p.MainWindowHandle = IntPtr.Zero
                System.Threading.Thread.Sleep(100)
            End While

            System.IO.File.Delete(s)

Merci de votre aide

Your save path is the Temp directory. It needs to have a filename too.

Ex:

System.IO.Path.GetTempFileName() + "myImage.png"

Good evening thank you for your solution
 I tried and the software tells me file not found.
Here is the error log

Ok, so go into the temp directory and verify that the file was actually saved there.

Good evening

no it is not actually

 

 While p.MainWindowHandle = IntPtr.Zero
                System.Threading.Thread.Sleep(100)
            End While

            System.IO.File.Delete(s)

the file is delete before being launched

 

Supend time is not long enough I will try another try

thank you

Why delete the file?

You're going way outside the bounds of what we can help you with regards to Paint.NET development. It sounds like you need regular .NET and VB help.

Hello Thank you for your answers ;

Rick:

Yes I am sorry, I have deviated a little from the development Paint Net; my original question was about it; I wanted to know if we could program directly in paint net a script to create a new document because the dialog box of the software is not appropriate for my use.

BoltBait: in fact it's true it's useless.Thanks

In any case thank you for your help and your time.
