MMM-GooglePhotos

I see that there is a comma missing at line 10 in between the || needs to be a comma.

sort: "time", //'time', 'reverse', 'random'|,|

I’m also not sure about the difference between ” and " (notice the slight angle) being a problem or not.

p.s. It’s pretty hard to read the code when only half of it is properly styled.

Is there a way to use this as fullscreen and have all the other modules still readable by putting a dark mask behind them?

@teitlebot set view position to “fullscreen_below” and modify css to add background to other modules.

@yupwho any luck with the dithering issue? I seem to be getting them on specific pictures although im not sure why just those.

Hi Thank you so much for creating this module I have set it up and been loving it!

The only issue I am having, however, is that when switching between images the module will fade to black for a second before going to the next photo.

Is it possible to remove this behavior and instead fade directly to the next image?

Thank you so much for the help!

@BryceTalbot
Possible by modifying source (showImage() of MMM-GooglePhotos) but not recommended. Because each picture size would be different, So the transition will make some annoying distortion on showing/hiding.

Any idea how I can get the monitor to rotate like this guy did except I want to use google photos? He created the code for arduino to rotate but the pi has to send a signal based on rotation of the photo.

@teitlebot you would have to do the same for google photos download… he could have worked out the horizontal vs vertical alignment of the picture…

google search for the stepper motor , A4988 Stepper

@BryceTalbot I solved that problem a while back…

need to use an onload() handler to process after the image is loaded but before shown.

the key is to minimize the total change to the dom, to reduce screen flash and dead space showing thru

so I load the images hidden and when loaded, calculate the size to make it fit on the screen without any stretch or clip. contain and cover styles both alter the image display.

then in the module dom contribution i append the image… (there might already be one being displayed)
and mark the image to be shown, with fade in
then I check if there are two, and if so, hide the 1st (with fade out) and then delete it from the dom contribution, leaving one image.

m here is a variable holding the size of the top margin
var m = window.getComputedStyle(document.body,null).getPropertyValue(‘margin-top’);

      // set the onload event handler
      // the loadurl request will happen when the html is returned to MM and inserted into the dom. 
      img.onload= function (evt) {

        // get the image of the event
        var img = evt.currentTarget;
        //Log.log("image loaded="+img.src+" size="+img.width+":"+img.height);

        // what's the size of this image and it's parent
        var w = img.width;
        var h = img.height;
        var tw = document.body.clientWidth+(parseInt(this.m)*2);
        var th = document.body.clientHeight+(parseInt(this.m)*2);

        // compute the new size and offsets
        var result = this.self.ScaleImage(w, h, tw, th, true);

        // adjust the image size
        img.width = result.width;
        img.height = result.height;

        //Log.log("image setting size to "+result.width+":"+result.height);
        //Log.log("image setting top to "+result.targetleft+":"+result.targettop);

        // adjust the image position
        img.style.left = result.targetleft+"px";
        img.style.top = result.targettop+"px";
        img.style.opacity =	this.self.config.opacity;
        img.style.transition = "opacity 1.25s";

        // if another image was already displayed
        if( this.self.wrapper.firstChild!=this.self.wrapper.lastChild)
        {
          // hide it
          this.self.wrapper.firstChild.style.opacity=0;
          // remove the image element from the div
          this.self.wrapper.removeChild(this.self.wrapper.firstChild);
        }

      }.bind({self: this, m:m});

I use this same methodology in a photo based calendar display module. it loads photos from google_drive, dropbox, and local file systems. But you cannot tell how big the image is (or its orientation) until AFTER it loaded.

@sdetweil I have the arduino and stepper motor all working and I see he has the orientation labeled in his javascript code but I have no idea how to get the mmm google photos JS to send a command to the arduino motor. Im not a real coder I can just play with other peoples code a bit.
