make Composite screen with image and text #104

PeuX · 2017-04-01T08:33:34Z

this is an extended TextPos to create composite screen with image and text.

PapirusComposite exemple

Thanks for this. Do you have any description of how it works so that we can add it to the readme?

shawaj · 2017-04-01T11:21:02Z

What does the change on line 23 of textpos.py do?

PeuX · 2017-04-01T11:31:31Z

the change on textPos allow Composite to extend textPos

Composite extend TextPos, so all textPos method are available (for text).

AddImage(image, x=0, y=0, size = (10,10), Id = None): Add an image to the screen ex : AddImage ('/path/to/image.bmp', 10,20,(20,20),'TOP') this add image "image.bmp" to the position 10,20 whithe the width 20 et height 20 and use the Top ref (as AddText From TextPos )
UpdateImg(Id, image): update image ex : UpdateImage ('TOP','/path/to/newImgae.bmp') change the image from the prévious ex with the newImage.bmp
RemoveImg(Id): remove image ex : RemoveImg('TOP') (it create a white blank image to set on the image to remove)

(sorry for my english,... )

So how would you use composite.py? And how would you use textpos.py now?

Can you provide some specific examples to help us with testing?

Thanks

here some code i use :
i use an externalised composite and textPos (they are in my project folder )

Ok thanks we will take a look at this in more detail next week. Still struggling to see how it would be used exactly to say write an image stored at /user/image.png and overlay that with the text "hello world" Perhaps providing a more generic example lone that would help? Can it be used from the command line at all? Perhaps there could be a good way to combine papirus-write and papirus-draw into one command later on.

PeuX · 2017-04-03T20:13:27Z

here some basic usage

from papirus  import PapirusComposite
screen = PapirusComposite()

screen.AddImage('./icons/rain.bmp',0, 0,(20,20),"img_weather")
screen.AddText("text rain",50,0,20,'txt_weather')

screen.UpdateImg("img_weather",'./icons/clear.bmp')
screen.UpdateText("txt_weather","text clear")

For the command-line, i don't know how that work...

3DJupp · 2017-05-06T09:51:04Z

Do you think it's possible to save the content as a temporary image and then rotate it by 180 degree?
This is what I'm trying to solve with PaPiRus, this improvement might be a step further.

francesco-vannini · 2017-05-11T14:11:48Z

Hi @PeuX , really nice class!

Could you please change the AddImage method to AddImg or change the others so that the method calls are consistent
Could you amend the init.py to include composite
Please provide a new version of the README.md with the class usage
It would be great but completely at your discretion, if you could provide a papirus-composite demo file to add to the bin folder

Many thanks for your contribution!

- Change papirus/composit.py to by more consistent whith textpos - add composite to __init__.py - provide demo in bin/papirus-composite-write (a really small demo)

francesco-vannini · 2017-05-17T09:18:43Z

Fantastic @PeuX , thanks.

vanillabrand · 2017-05-22T16:21:08Z

This doesn't work on current release. When will it be live?

francesco-vannini · 2017-05-23T06:33:59Z

Could you be more specific? We pulled the code in last week and tested it.

The PapirusComposite class inherits from PapirusTextPos. The code in the PapirusComposite init function requires the PapirusTextPos class to inherit from object (so called new class).
The object argument was readded by Francesco on May 18 in commit b65a91b#diff-d6287b584fd2b4213720ee5e0b974eb5.
The object argument disappeared on May 17 because of the merge in 7c786e5#diff-d6287b584fd2b4213720ee5e0b974eb5.
In case @vanillabrand retrieved the code in between these two commits the composite code would not have worked.
Cannot test now, since I am on travel.

shawaj · 2017-06-12T15:04:34Z

@francesco-vannini did we test this? it is working ok now?
