Normal topicArtwork Scaling Issue

On some images, and it is difficult to predict when it will happen, I scale the artwork down to 800X800 as that is the maximum artwork image size that my Audi will display on the MMI for files on SD cards.

I select scale artwork and enter 800 in the "scale down to:" box.

When I apply, sometimes it works and the image scales to 800X800. Other times it scales to 1600X1600 and I have to enter 400 to get it to 800X800.

Is this a bug or does it have to do with the image being scaled?

I saved artwork from music I downloaded and attached to the message.

Yate always scales based on the raw number of pixels. I've scaled your attached image down to 800x800 and it works as expected. As of Yate v6.3, the PPI of an image is preserved. It's possible that your car is expecting 72PPI images and the initial image was 144PPI. Either way the number of pixels will be the same after Yate resizes the image. If you have not yet updated to v6.3 I suggest you do so as it preserves PPI when saving or modifying images.

I'm assuming that you're scaling inside the Crop/Scale/Square Artwork panel. There is a setting (in v6.3) to force the PPI. Try selecting 72PPI.

When you see unexpected sizes after scaling are you viewing the image in Yate or a different application? As I said I've tried your image and it's working for me. I tried it on a Retina and non Retina display Mac.

I am using 6.3. I typically upgrade whenever alerted on startup.

I am using the crop/scale window.

Here are two screenshots. One that shows the original and the settings I made in the dialog.

The next is the result.

The only way I get this to 800X800 is to set the scale down to 400

That's very strange. Was the file saved with the image before you resized it? Or did you add the image and then resize before saving? Are you on a Mac with a Retina display or not?

The image was embedded in the flac that I downloaded from the record company website. I have a mac with a retina but that is displaying on an external 27" Dell ultrasharp display. So your comment about the display that I was viewing on made me switch to the Mac display instead of the external display. when I scale on the retina it works correctly. which to me is even weirder that the display that the app is running on impacts some scaling factor with images.

I guess I'll just use the internal display... but the scale of an image seems to me to be irrelevant of the display. However the results are consistent when just moving the app from display to display....

Strange and stranger. Yate has to test for a Retina display before doing anything on an image. The 'retina' property is very relevant as required sizes have to be manipulated on a Retina display. When you say you want 800x800 on a Retina display, Yate has to draw into a 400x400 image space to do any manipulation. A 400x400 image space on a Retina display is an 800x800 pixel image. This halving is not done on displays which do not report as being 'retina' displays. It works because I tested on an old Apple 32" Cinematic Display.

It seems top me that your display is not reporting itself as being a Retina display but that somehow the system is messing something up. You're getting 1600x1600 because I'm drawing into the 800x800 space and the system is somehow still thinking of it as a retina image.

Thinking too hard on this is giving me a headache. I'll investigate a little more but perhaps I have to base things on the default display always. It's not logical but who knows?
