Eclipse Icons are really small on high resolution screen

Question

As the title says, the icons in Eclipse are really small on my 2560x1600 laptop screen. I find that even turning down the resolution and plugging it into my 1080p monitor still results in the icons being tiny.

I found an answer that led to this site: https://github.com/davidglevy/eclipse-icon-enlarger but I have no idea how to use that. Could someone please help?

Thanks in advance

The author posted instructions for his tool here. Basically, you have to run it from the command line and need to specify the Eclipse base directory. The tool will then iterate over all directories in order to double the size of all icons.

Syntax for usage is:

java -jar eclipse-icon-enlarger.jar \
            -b <Your Eclipse base directoy> \
            -o <Desired output directory> \
            --resizeFactor <Factor for icon increase>

Sorry for the newbie question, but where would I get that .jar file from? – demar Aug 31 '15 at 19:34
You can find a JAR file [here](https://github.com/imzcy/eclipse-icon-enlarger-binary/releases/download/0.0.0.1/enlarger.jar). It's name is different, but it's based on the same project. – user1438038 Sep 01 '15 at 06:50

This has been fixed in the latest version of eclipse, Eclipse Neon:

SWT now automatically scales images on high-DPI monitors on Windows and Linux, similar to the Mac's Retina support on OS X. In the absence of high-resolution images, SWT will auto-scale the available images to ensure that SWT-based applications like Eclipse are scaled proportionately to the resolution of the monitor.

For comparison, here's how it looked in Mars without high-DPI support:

Another way that I discovered is to modify your registry file.

Open regedit and go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide
Add a new DWORD (32-bit) Value: PreferE‌xternalManifest with a decimal value of 1
Go to your eclipse folder and create a new file: eclipse.exe.manifest and add the following text to the file:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3">

  <description>eclipse</description>

  <trustInfo xmlns="urn:schemas-microsoft-com:asm.v2">
    <security>
      <requestedPrivileges>
        <requestedExecutionLevel xmlns:ms_asmv3="urn:schemas-microsoft-com:asm.v3" level="asInvoker" ms_asmv3:uiAccess="false">
        </requestedExecutionLevel>
      </requestedPrivileges>
    </security>
  </trustInfo>

  <asmv3:application>
    <asmv3:windowsSettings xmlns="http://schemas.microsoft.com/SMI/2005/WindowsSettings">
      <ms_windowsSettings:dpiAware xmlns:ms_windowsSettings="http://schemas.microsoft.com/SMI/2005/WindowsSettings">false</ms_windowsSettings:dpiAware>
    </asmv3:windowsSettings>
  </asmv3:application>
</assembly>
