Build Identifier: I20100608-0911 Windows *.ico files can include 256x256 images. These are visible, for example, with View>Extra Large Icons. However, an Eclipse RCP application cannot specify a 256x256 image on the *.product wizard on the "Launching" tab, and *.ico files including a 256x256 image are not accepted. An example of this can be seen in the launch icon for the Eclipse Helios Java IDE. Given: - A 256x256 image is included in the *.ico file specified in an RCP app's *.product, on the Launching tab, under "Program Launcher," on the win32 inner tab, in the "Use a single ICO file containing the 6 images." - The Windows Vista explorer can display the icon at all resolutions. Observed: - A warning is provided by the *.product wizard: "The specified path does not point to a valid image." - The default Eclipse icon is used on the exported product, at *all* resolutions. Expected: - The *.ico that worked in Windows would also be accepted by Eclipse. - The 256x256 image would either be used (ideal) or ignored. Reproducible: Always Steps to Reproduce: 1.A 256x256 image is included in the *.ico file specified in an RCP app's *.product, on the Launching tab, under "Program Launcher," on the win32 inner tab, in the "Use a single ICO file containing the 6 images." 2. 3.
PDE/Build can only replace images that already exist in the launcher binary, it can't add or remove icons. Open question is this: what happens if a 256x256 icon is added to the launcher and RCP apps don't start including this icon. They are left with a 256 sized eclipse icon and then their own small icons.
Andrew, in that case -- when a 256x256 is missing but others are not -- could the behavior be to generate a 256x256 from the closest specified image? (It wouldn't have to be interpolation for smaller images; could just drop the image pixel-for-pixel onto the larger 256x256 grid. Looks like this is what Windows Vista does.)
The problem is worsened by the fact that eclipse.exe contains a seventh image at 24x24 resolution. For some reason, Windows 7 decides to use that icon for all display sizes except 'Details' (or 'Small Icons') in explorer. Given: - An *.ico file containing the required six icons at correct resolution and bbp is added to the product configuration - The product is exported normally Observed: - With explorer view set to "Details", the correct icon (16x16) is shown - When explorer view is set to "Medium Icons" or larger, the Eclipse icon is shown. - The executable inspected with an icon editor reveals a 24x24 eclipse icon in the executable. Expected: At all zoom levels, at least some rendering of my own icon should be used.
