ImageData loader with 1bpp images [message #1834012]

Hi,

I'm currently updating an SWT stand-alone application with the libraries from 2020-06 release (4.16) and seems that the ImageData loader doesn't load 1bpp (one bit per pixel) images as paletted images anymore, and seems that all images are loaded as 32-bit images.

With the previous version from release 4.6 the image were loaded as 8-bit per pixel paletted.

Is that right ?

I managed to get the paletted imagedata back with getPixel / setPixel, but I'm wondering if there is a flag or some setting to have the previous behaviour.

I'm using Linux (Ubuntu 20.10, 64 bit), the image is described as "PNG image data, 256 x 128, 1-bit colormap, non-interlaced".

Best regards,
Marco
