Wait a second, I'm confused.....

People actually pay for software???!!

Quoted from Tuborg

When you say "work in quadrants" is there a method / mechansim to split the large file (72MB) into say 9-files and combine them later when completed?  

Yes, divide the original scan into sections using guide lines, Copy and create a new, smaller file to work with. I don't know if PSP can do that but I would think so. If you have difficulties you could send me the file via ftp and I'll cut it up for you. Wouldn't take long for me to do at all.

Someone needs remedial math..  QUADrant..  as in 4???  lol   jk...

Hmmm.   I guess to preserve the same detail, I could work on the original size, but lower the DPI.   The original scan is 200dpi - so lowering to 100dpi would effectively change the size.   I found the detail was hard to capture when working at that level.   I actually oversampled from the 200dpi to 300dpi so I would have more detail in terms of the shapes for the whiskers / leaves / dots / etc.     With the 200dpi - the dots were just 4-square pixels with no shape.

Actually oversampling from 200dpi to 300dpi isn't the best idea, because all it does is blur the existing pixels to fill the gaps.  What I was saying was to drop the image size down by 50%, not the DPI.  Leave the DPI at 300.. basically you're re-sampling it.  You won't lose any detail, you'll just have a smaller image to work with (but the same amount of pixels) which means you'll have to zoom in closer.  It should drop your memory usage right down.. hope that makes sense.

although you're working with a fairly powerful PC there.. probably the equivalent to my Mac here at work.

Also avoid using JPEG compression.  It's not loss-less, you'll see some artifacting which could mess up your work.  Also, the image is uncompressed by the software when you're working with it anyway, so it doesn't save you any trouble.  Use uncompressed TIFF or EPS files instead.

Hope all that helps!

Yup - it definitely helps.   Thanks.  

I'll play some more tonight with breaking this down.   I basically have an almost perfect bitmap image now in PSP.    That is, I've corrected all the flaking / scratches.   And I believe my black is "pixel" perfect or close to it.    I'm willing to start all over again - as each time I'm learning more.   I believe, by the CPR tutorial, you just touch-up in bitmap the black.   The other colors are traced in the vector program.

As far as  the other colors in the bitmaps go, there's still color-distortion due to some paint lifting off so the scanner picks that up as a different color.   Using the magic-wand/color-change is not possible except in small, small steps.   But with this bitmap, I'm ready I believe for the next steps of isolating the colors and vectorizing.

OTTOgd, I may take you up on your offer, but I'll see if those commands exist in Corel PSP.   Once broken-up, is there similar commands/techniques to re-join them.

MrMikeman.   Yup.  Circle, Triangle, Square are about as complicated as I get.   Quadrant is any grid pattern to me     And I did well in math.  English is where I struggled.
