Containers for photos, with scroll, drag&drop between them

@jmv38 did you try ui.RENDERING_MODE_ORIGINAL
-
@jmv38 this is ok, I think
img = ui.Image('iow:refresh_32')#.with_rendering_mode(ui.RENDERING_MODE_ORIGINAL) b.image = img b.tint_color = 'gray'
-
@cvp thanks.
but it still doesnt work: now the button shows in gray, not white, and is not visible on my gray background.
I wonder how to get it simply as it shows in the editor? -
@cvp you know what? it works with ORIGINAL
looks like omz inverted TEMPLATE and ORIGINAL values
thanks. -

@cvp i have finished my first version of the program
here https://gist.github.com/1b67ba85ca7bd7b23c7058216895372c
this will:- let you choose an album xxxx
- load the 200 first pictures
- present them in a photopicker
- from which you can build photo album pages (collage)
- it creates 2 new albums:
- xxxx_pages : the album pages
- xxxx_pages_and_photos: as it says. useful to upload the album in photoweb printing service for instance
- your own photos and albums are not modified
to see how to use it tap ‘?’ button: it opens a youtube video that shows it in action.
It is designed to work in lanscape mode
let me know how it works for you. -
@cvp hello again!
I am trying to make a high definition image with draw_snapshot()
I works fine until the context width is 4000, but i get a black image when the context width is 5000 or more. I need 9000....
Any suggestion?
Thanks. -

@jmv38 this works for me
import ui iv = ui.ImageView() iv.image = ui.Image.named('P1020096.JPG') # 3888 x 2592 pixels wi,hi = iv.image.size iv.frame = (0,0,wi,hi) print(wi,hi) # 3888 2592 w = 2*wi h = 2*hi print(w,h) # 7776 5184 with ui.ImageContext(w,h) as ctx: iv.draw_snapshot() ui_image = ctx.get_image() with open('t1.jpg', 'wb') as f: f.write(ui_image.to_jpeg(0.9)) # 15552 x 10368
-
But 9000 x 6000 crashes..
-
@cvp thank for the info
i check again -
@cvp i had forgotten that 4000 is really 8000 because x2
i think 8000 should be enough for prints 60 cm wide => thanks. you saved my last week of coding!However it is strange that 15000 is ok bu not 9000...?
Concerning the use of the project without any album, i could modify this for you if you are really interested in using this code. Are you?
thanks.
-
@jmv38 Not interested actually, thanks. If needed, I'll create an album.
-
@jmv38 During my tests and my multiple crashes, I'm pretty sure I have seen a red message during one microsecond, containing the words Decompression Bombs
This is a [PIL message](Decompression Bombs) .
I didn't use PIL. Perhaps the ui.Image.save uses it...Something like, it not sure, message disappeared immediately
/usr/lib64/python2.6/site-packages/PIL/Image.py:2261: DecompressionBombWarning: Image size (166109750 pixels) exceeds limit of 89478485 pixels, could be decompression bomb DOS attack. DecompressionBombWarning) -
@jmv38 said:

15000 is in pixel, already multiplied by 2. The width was 7776, just < 9000
-
Same crash with
Image.warnings.simplefilter('error', Image.DecompressionBombWarning) Image.MAX_IMAGE_PIXELS = 100000000000
-
@cvp 5000 doesnt work for me and 5000<7000
-
@jmv38 and Sure that you don't have two pixels py point?
What is your device? -
@cvp i do have 2 pixels per point (ipad air)
i dont crash, it is just that the image saved is black
i checked that 4x1024 is ok and 4x1025 fails
i remember this ios limit 4096 from somwhere. -
@jmv38 could you post your code, only this part, and the image you use?
