I guess they both can be as small as possible although he also reckons the 'compile file' (which uses the original satellite image and the water and blend mask image files) ends up smaller too. Maybe it's a personal preference but the guy who was replying to my thread at suggested that I export the BLEND mask (layer where everything the user doesn't want to show painted with a 25% BLACK brush so the edges are a greyscale and blend nicely) as a 8bt 256 grayscale TIFF image and the water mask which is painted with a 100% BLACK brush as a 1 bit 2 color (black and white) TIFF. Transparency (an alpha channel) remove it The mask is an 8-bit tif using only black and white This gives water characteristics to anyīlack area. Layer -> Transparency -> Remove Alpha Channel If your image has transparency (an alpha channel) remove it This gives water characteristics to any black area.

(and ignore that Imagemagick command line, same as a Gimp grayscale with alpha. A layer mask in Gimp is B&W where black is 100% 'transparent' and white is 100% 'opaque'.

However, are you sure you are on the correct track, what does flight simulator require. You can try a png with mode set a indexed 1 bit. Not all applications respect an alpha channel. Maybe I can EXPORT to another format then import into Paint Shop ProĪn alpha channel is just a mask which tells the particular graphics application used that any pixel is 'transparent' often represented by that checker board pattern. I have seen reference to alpha channel but don't know that they are.Ĭould you explain what an alpha channel is and is there a method ofĪdding a layer which is not an alpha channel?

Maybe I can EXPORT to another format then import into Paint Shop Pro convert and save? Could you explain what an alpha channel is and is there a method of adding a layer which is not an alpha channel? I have seen reference to alpha channel but don't know that they are. Give them as much info as possible, add a link to an example image if I suggest asking on the ImageMagick forum, where they are very You can see the file properties from the screenshot. The best I can suggest is not Gimp but command line ImageMagick.ĭepending on your OS (I use linux) a commandĬonvert file.tif -channel rgba -alpha on -colorspace gray out.tif I can see what you are trying to do, but.īy definition 1 bit is black and white.
