Need a line technique/tutorial

[SMR]

Im looking for help on making lines through images.
Not your typical scan line,but offset lines.Such as the space between the lines gets seperated buy more pixels ever other time.
Say it starts off with the line,then a 1 pixel space.Then another line,then a 2 pixel space,another line,4 pixel space and so on.
I have done it manually by making a 1x100 blank and counting,then making a pattern of that,but the thing is,once the pattern has what I did,it starts over rather than going on forever.

I hope this makes sense.

What program?

Dunno if this is going to help you any but...

make a greyscale fade from white to black (convert to greyscale after if it isn't already)

Convert it to bitmap mode with a halftone screen (frequency=10, Angle=0, Shape=line)

Convert it back to greyscale.

Do a motion blur (distance=999, Angle=0)


But you probably need it in colour and solid lines right?

Im goona give that a try and I'll let you know.
Thanks for your help.

Well here is the result.Pretty damn close so I will see what I can do to get exactly what I need.
I first made a 1x480 blank and did what you said.I then made a pattern out of it and this is the result on a test canvase.

Youch. Did you use LINE and 0 angle in the halftone settings cuz it doesn't seem as clean and evenly spaced as it should be.

but there's got to be another way

The first time I messed up,sorta.I did it again and it came out like yours.
This is what I need but then the white area would need to be blank then would need to get the black area to be the overlay area of any image then selcted,then click on the image wanted with the style and cleared.
I think this is coming out confusing in words lol

You are right though,there has to be and easier way,such as a plugin that removes sections like that from and image.Maybe a halftone line plugin.Because your going to want an infinite number of lines/spaces depending on the image size.
Im still messing around with it though.I should turn on my veiwlet cam incase I do get it and and forget the steps ahahaha

Thanks for the help though.Much appreciated

Don't you mean the lines are the same thickness each time but the space between those lines gets bigger by one each time????

I think thats how it goes /emoticons/icon_mrgreen.gif
I couldnt find an easy way to say it so tried a few things to see if I could 'show'
Here is what I just made by hand (no filters,just using rectangular marquee - SHIFT - DOWN ARROW )
This way would take some time to produce on large objects seeing as you would have to count spaces as you go down.There has to be an easier way.

The 'black' areas would say be the area over an image,then select/create a new layer,make the image in the attachment,then select all the black areas or vise versa,and then delete them while on the other layer.....make sense?

p.s. click the attatchment,it looks solid black but it is not.The white area is to be transparent.

Create a long rectangle with the marquee tool. Set the height to 1 pt. in the Transform palette. This will be your first/topmost line.
Alt-drag the rectangle down and set the height of this second box to 2 pts.
Alt-drag the new rectangle down and set the height of this third box to 4 pts.
...and so on, using definite values for the height so that it's exponentially accurate (1,2,4,8,16,32... or 1,2,4,7,12,18,25,33...).

When you've created enough rectangles to more or less fill your image, select them all and distribute so they are equidistant from each other.

If I understand your dilemma right, then this should allow you to create the effect you want without you having to count spaces. Hope this helps.
