How do you do this in PaintShop Pro? Reducing # of colors

[Jillq]

How do you do this in PaintShop Pro?
"The palette can then be further reduced for individual images by prunning the extraneous colors and forcing the "close" ones to conform. "

I want to change images to using fewer or possibly websafe only colors so they'll download faster.

Thanks

2 ways.Depending on the version you are using it may a bit different, but:

From the Image menu, select Decrease Color Depth.

Or when Saving the image use the File -> Export JPEG, GIF, or PNG optimizer.

If you choose either PNG or GIf you can choose several options including Using a Web Safe Palette.

Jpeg will by default use a Web safe palette

Vacunita,

I started to use the image menu, then got fooling around with the optmizer. Using a jpeg file, I used the PNG optimizer, optimized it, and saved the jpeg as a PNG fie. The file works fine in Firefox and IE. Is there anything for me to worry about with this 2 in one method?


Thanks,

Not really, all you did was just limit the amount of colors available to the image, and then just optimized it for the Web in a different format.

Nothing to worry. But in the future you may want to choose one method or the other, as sometimes you may end up with unwanted results if the amount of colors is to low for a proper display of the image.

Vacunita,

I agree.

Thanks for the help,

I suggest you create, and save your images in their full-colour splendour, probably using PSP's own .pspimage format to preserve any layers, etc.

Then, use the JPEG/GIF/PNG optimizers to generate additional cut-down versions for use on the web. That way, if you decide you want to raise/lower the quality of the images in the future, it's easy to do so.

Bear in mind...

JPG images are always full-colour (well, unless you make a grayscale one), you make them smaller by increasing the amount of compression in the algorithm - overdo it and you get extra lines showing up around all the edges in your image. You tend to use jpg for photographs.

GIF images have a limited pallette of colours, and you can reduce file size by lowering the number of colours. You tend to use Gifs for icons & diagrams.

PNGs can be either limited pallette or full colour, you can use them for almost anything.

"Web safe" colours are completely irrelevant in the 21st century - they only apply to people using 256 colour screens, and when's the last time you saw one of those?
