This bug is PackageMaker (and Installer?) does not support PNGs in packages. It was filed on 2006-05-19 at 02:00 PDT.
PackageMaker/Installer should support the use of PNG image files in Installer packages.
Steps to Reproduce:
- Create a package in PackageMaker.
- On the first step of the Interface Editor, drag a PNG file onto the window, or click Custom Background Picture and choose a PNG file.
The PNG file is accepted as the background of the package.
The PNG file snaps back (drag), or is disabled in the list (choose file).
As far as I know, Installer has never supported PNG files.
PNG supports compression, for smaller Installer packages. True, Installer packages are often distributed on compressed disk images or in compressed zip archives, but PNG can “filter” the image bytes to be more compressable, resulting in greater savings.
