I propose to modify the output images bitcoin.png v0.13.2 #9742

I noticed that in windows, there is a large picture instead of a small

bitcoin.png size 1024 x 1024

and this picture is used in the bottom Wndows 10 menu it shrinks and does not look nice There is a maximum size should be 32x32, offer to fix

Also, there is a flaw in ubuntu 14.04, there is the icon merges with the text bitcoin

Thanks for the report: can you post a screenshot?

I remember we use a multi resolution ico for windows, no?

Agree screenshots are helpful to document the issue.

To achieve a flexible icon during runtime (testnet/regtest), we set the Icon during BitcoinGUI init. The relevant function is getTrayAndWindowIcon() which should return a 256x256 Icon. I expect Qt (or the Os) to downsample is correctly.

here is an example, as you see bitcoin.png they use everywhere, but its size is too great and in the sources there are many other sizes

@Datasec: Why is the size to big?

It looks good on your screenshot? Doesn't it? The source should contain a large enough "base" icon for future changes (HiDPI is getting more popular for Linux and Windows as well).

@jonasschnelli This change is not particularly important, the icons look fine

But I think it's better to use icons that fit the size :)

Looks good to me, there is no problem here. The base icon is large to allow scaling to different screen resolutions, and smaller icons are used where necessary.
