MMM-BackgroundSlideshow

CyruS1337

I have a question about the background photos. I’ve found that the images are larger when viewed on the raspberry than when I look at them on the PC.

I am using the MMM BackgroundSlideshow module to display a new image every 10 seconds.

In custom.css I have the following codes deposited:

.MMM-SystemStats  {
        color: #CEF6CE;
        } 
.normal,
.dimmed,
header,
.MMM-BackgroundSlideshow  {
    color: #fff;
},
.MMM-EasyPix  {
        font-weight: 400;
        } 
.MMM-SystemStats {
    font-size: 45%;
}
.MMM-darksky-hourly {
	color: #ffffff;
    }

Can someone tell me why the PI are “bigger” than when I look at them on the PC

That’s still my config

Ok, thanks for your help. I downloaded the program PhotoScape and changed the height and width of all photos. Look, there you go !! Thank you

CyruS1337

Enclosed I send you the two different views. Once on the PI and once on the PC monitor.

I’m not sure, I don’t know anything about backgroundSlideShow, but,

Your pictures would be greater than resolution of screen.
Then, your PC viewer might have resized your pictures automatically when they were shown. But backgroundSlideShow might not have that feature. However, there is a possibility of controlling by CSS. Ask to creator.

@sean Thanks for your quick reply.

@sean Thanks for your quick reply.

I also use this module very successfully. Try to resize the pictures to the resolution of your screen (photoshop), normaly 1920 x 1080, 1024 x 760. Sometimes it is also necessary to set the pictures to the correct aspect ratio 16:9. For me it works fine.

@garbleflux i had to modify another image display module to get the correct presentation of images, no zoom in and no crop of portrait mode. does mean that some of the background shows thru, but the pictures are correctly displayed

CyruS1337

@sdetweil And what would be your module

sdetweil

@cyrus1337 I am using the MMM-ImagePhotos module… but I had to change the code to keep my images properly formatted…

landscape

portrait
https://www.dropbox.com/s/htxdm7b8sayqazh/IMG_20181114_102350.jpg?dl=0

can’t get the pics to actually display here…

Sean

I made several modules handling photos - MMM-GooglePhotos, MMM-WeatherBackground, MMM-DropboxWallpaper,…

All modules can display photos by its aspect-ratio with covering the target area or resizing to show whole picture.
Try them.

MMM-DropboxWallpaper (https://github.com/eouia/MMM-DropboxWallpaper)
MMM-GooglePhotos (https://github.com/eouia/MMM-GooglePhotos)

Sean

Anyway, If your module would be using img tag for showing photos, module should know the exact image size and calculate to resize it by proper target ratio.
Instead, I prefer using Background CSS trick. background-size:cover will cover whole image to entire area of it’s element, background-size:contain will resize image to fit to target element size. Suprisingly, without any calculation.
