This tutorial will help you when creating tubes from .jpg images with WHITE backgrounds.
Inevitably the white backgrounds contain discoloured pixels that are not pure white.

If you have downloaded a large image
DO NOT resize it to a smaller, workable size.....
we will do this later when the tube has been created.

PART1/1

Open up the
Vampyroteuthis_illustration_2 image in your PSP workspace
WINDOW >>> DUPLICATE
Close the original Image
LAYERS >>> Promote background Layer

This is a GREYSCALE image....

PSP9: IMAGE >>> INCREASE COLOUR DEPTH >>> 16 MILLION COLOURS (24Bit)

For some reason in the higher versions of PSP we need to DECREASE
instead of INCREASE the COLOUR DEPTH ... go figure!!!


PSPX- PSPX5: IMAGE >>> DECREASE COLOUR DEPTH >>> 16 BITS CHANNEL (24Bit)





PART1/2

LAYERS >>> NEW RASTER LAYER

Flood fill with WHITE

LAYERS >>> ARRANGE >>> MOVE DOWN

ACTIVATE RASTER 1

EFFECTS >>> TRANSPARENCY >>> Eliminate White

We lost some of the colour on the image... so....
LAYERS >>> DUPLICATE (Twice)

LAYERS >>> MERGE >>> MERGE VISIBLE


PART1/3

OK... the background still looks 'grey'... no problem..

Depending on your image background you
will have to adjust the "Tolerance".
This one needed a tolerance of 20.


With your MAGIC WAND
Mode = Replace
Match Mode = RGB Value
Tolerance =
10
Feather =
2
Antialias = UNchecked
Sample Merged = UNCHECKED
PSP9 - X3: Check CONTIGUOUS
PSPX
- X3: There is no " Sample Merged"
PSPX - X3: Use all layers = UNChecked


and while depressing your SHIFT KEY...
click on the 'grey' area including the 2 areas shown
at the right side of the image
PART1/4

Hit your DELETE key twice

DESELECT

LAYERS >>> NEW RASTER LAYER

Flood fill with RED

This is so you can see of there are any areas
that havent been deleted cleanly

LAYERS >>> ARRANGE >>> MOVE DOWN

We need to remove the text
PART1/5

Activate Raster 2

Choose your SELECTION TOOL
Selection Type = Rectangle
Mode = Replace
Feather = 0
Antialias = UNChecked

Select the text
PART1/6

Hit your DELETE key

DESELECT

IMAGE >>> RESIZE =
90%
Ensure "Resize all layers" is UNCHECKED
Resample using WEIGHTED AVERAGE

Select "Create selection from:" >>> Layer opaque



PART1/7

You will see there is a large area to the left of the image..

we need to eliminate this

PART1/8

Click inside the 'marching ants' ...

Oops.. there are stray pixels...


Choose your FREEHAND SELECTION TOOL
Selection Type = Point to Point
Mode = Replace
Feather = 0
Antialias = UNChecked

Select the area around the image making sure all stray pixels are outside your selection.




SELECTIONS >>> INVERT
EDIT >>> CLEAR
DESELECT


PART1/9

Now, if you zoom in on this image you will see
there is still a white edge


PART1/10

With your MAGIC WAND
Mode = Replace
Match Mode = RGB Value
Tolerance = 10
Feather = 4
Antialias = UNchecked
Sample Merged = UNCHECKED
PSP9 - X3: Check CONTIGUOUS
PSPX
- X3: There is no " Sample Merged"
PSPX - X3: Use all layers = UNChecked


Select the area outside the image

Hit your DELETE key 10 times

DESELECT

PART1/11


Select "Create selection from:" >>> Layer opaque

This should be your result
PART1/12

IMAGE >>> CROP TO SELECTION


Delete the bottom (red) layer

Save as .psp image
PART1/13

Now, let's do something with it...

Open a new image 600 x 600
Transparent background
PSPX - X2: Colour Depth = 8bits/channel
PSPX3: Colour Depth RGB = 8bits/channel

Flood fill with
WHITE

EFFECTS >>> TEXTURE EFFECTS >>> SCULPTURE
PATTERN = ocean4

PART1/14

Right click on theTitle Bar of the tube you just created
and select COPY from the options

Right click on the Title Bar of your ocean image
and select PASTE AS NEW LAYER from the options.


IMAGE >>> RESIZE = 75%
Ensure "Resize all layers" is UNCHECKED
Resample using WEIGHTED AVERAGE


In your LAYER PALETTE change the
BLEND MODE to LUMINANCE (L)


Now.... I'm sure you could expand on this to make a tag. *S*

PART2/1

Now, let's try another image


Open up the bat_500 image in your PSP workspace
WINDOW >>> DUPLICATE
Close the original Image
LAYERS >>> Promote background Layer


EFFECTS >>> TRANSPARENCY >>> Eliminate White

You will notice the wings and part of the body have become semi-transparent



PART2/2

If you... Select "Create selection from:" >>> Layer opaque (same settings) now...

You will see it does NOT surround close to the extremities



This means there are stray pixels ...

Click inside the marching ants and they will become visible



DESELECT

PART2/3

LAYERS >>> NEW RASTER LAYER

Flood fill with WHITE

LAYERS >>> ARRANGE >>> MOVE DOWN

LAYERS >>> MERGE >>> MERGE VISIBLE

With your MAGIC WAND
Mode = Replace
Match Mode = RGB Value
Tolerance = 25
Feather = 4
Antialias = UNChecked
Sample Merged = UNCHECKED
PSP9 - X3: Check CONTIGUOUS
PSPX
- X3: There is no " Sample Merged"
PSPX - X3: Use all layers = UNChecked


Select the white area

PART2/4

Hit your DELETE key 5 times

DESELECT


Select "Create selection from:" >>> Layer opaque



If it surrounds only the extremities of the image you can
just about guarantee that the image is clean.


PART2/5

DELETE the red layer

and

Save as
.pspimage
PART 3

Ever see an image you'd love to use in a tag but don't know quite how to go about it????


PART 3/1

Open up the
black-and-white-backgrounds image in your PSP workspace
WINDOW >>> DUPLICATE
Close the original Image
LAYERS >>> Promote background Layer
PART 3/2

Now if you use your Magic Wand with the same settings and select the white area at the bottom right
while depressing your SHIFT key thus far....



As soon as you select the remaining area it will select more areas than required.



If you play around with reducing the TOLERANCE
you would eventually be able to select the required area.
PART 3/3

BUT... if you...

EFFECTS >>> PLUGINS >>> Mac's >>> Remove White

LAYERS >>> NEW RASTER LAYER

Flood fill with WHITE

LAYERS >>> ARRANGE >>> MOVE DOWN

LAYERS >>> MERGE >>> MERGE VISIBLE

Then with your MAGIC WAND... same settings BUT change
TOLERANCE to 20
FEATHER to 3
and while depressing your SHIFT key

Select the bottom right area it shouldn't overlap into the striped area.



PART 3/4

Depress your DELETE key 3 times

DESELECT

PART 3/5

Now, this image is huge ... so....


IMAGE >>> RESIZE = 50%
Ensure "Resize all layers" is UNCHECKED
Resample using WEIGHTED AVERAGE




Select "Create selection from:" >>> Layer opaque




IMAGE >>> CROP TO SELECTION

and

Save as .pspimage


Now you can do all sorts of things with the image

For example
PART 3/6

Using
EFFECTS >>> DISTORTION EFFECTS >>>
POLAR COORDINATES

PART 3/7

Then if you
EFFECTS >>> REFLECTION EFFECTS >>>
ROTATING MIRROR


You end up with this






If you go back to the result you got in PART 3/6
Then...

EFFECTS >>> DISTORTION EFFECTS >>>
WAVE



You end up with a new shape to work with..




I hope this has given you some ideas when creating tubes.
