Plugin request - a variation of the pixel counter plugin

[heathersharmony]

Is this where I post a plugin request? It would be a variation of the pixel counter plugin or something similar.

[toe_head2001]

Sure. How do you want to count the pixels? By color? Opacity? Or what do you want the plugin to do?

Is there a way to have it measure the beginning and end of areas of pixels in an image and show them either in cm or inches as in the photos?

The beginning and end of areas with black pixels? ignoring the white pixels?

 

What's wrong with just using one of the Selection tools? They will tell you the area in cm, in, or px.

Yes, ignoring the white. I'm looking for a plugin that would put the cm, inches, etc into a spreadsheet

[pdnnoob]

In fact, if you want to save the trouble of manually using the rectangle tool to get at the edges, you can use the magic wand tool to select what you need a measurement of and it will give you the dimensions of the bounding rectangle in the info bar at the bottom of your screen.

EDIT: I've been ninja'd!

Putting the information into a spreadsheet automatically is a different story altogether. I don't know if that is within the capabilities of a plugin, but if it is, I know several plugin authors around here that would be able to figure it out faster than I can type a response.

[toe_head2001]

A Comma-separated values (CSV) based spreadsheet wouldn't be difficult, as the format(s) of the file is dead simple.

 

I'm not necessarily volunteering to make this, but more information is needed.

-Do you want to ignore all the white pixels? or just the ones on the edges before there is a black pixel?

-Do you have an example of how you would want the spreadsheet to formatted?

-Would the plugin create a new spreadsheet every time it is run? or append to an existing one?

 

Anyone know if plugins have access to DPI information?

I've published a CSV filetype - sing out if you want the code Toe-y.

[heathersharmony]

Here is an example of how the spreadsheet would look except there may be more than 2 columns if there is a break in the non white pixels. It would create a new spreadsheet each time it is run. In the sample image there are open areas within the image so there may be multiple beginning and ends of pixels within one column. This would be used for a book folding pattern and would allow one to to cut and make more than two folds per page.

It has to be a very accurate photograph that would match the book exactly. If it had a height and width box for output scaling would that do?

Heather,

Here's my first stab at the new spec's, tell me what you think. It's in PDN4, let me know if I need to downgrade.

[heathersharmony]

I tried out the pixelcounter2 and I think it's starting top to bottom and measuring white areas. I need it to measure from left to right. It can keep it in pixels if that is easier but I would need to know how to convert it then to centimeters or inches. Also when I opened it in excel it had blank rows between each page number. Is there a way to have duplicate pages go,across the sheet....having more columns in the spreadsheet? The one pattern I tried it on ended up with over 200 pages trying to print out

Do you mean the book is lying on it's side not standing on it's end?

[heathersharmony]

The book will be standing. What I mean is when I compared the pixel count output to the image it looks like it is going from top to bottom. It needs to read the image from left to right since that is how the pattern is followed for marking the book.

[heathersharmony]

The original pixel counter was based on only making one fold per page...so two measurements marked per page. I would like to expand on that and have multiple measurements per page based on the pattern and cut between each two marks so you would be able to make more than one set of folds per page.

[heathersharmony]

Can the original pixel counter plugin be used this way?

[TechnoRobbo]

yes it did multiple folds per page 

 

pages were scanned top to bottom before moving left to the next page.

[heathersharmony]

Yes

[TechnoRobbo]

Are you absolutely sure you want left-> right  then Up_Down. That's totally different from the first pixel counter 

 

That would make the page numbers no longer sequential? I can flip it but the results doesn't make sense.

 

Attached is an update with 2 columns.

 

 

 

Just put type in the book height in inches and it will calculate the ruler measurement for the fold.

[heathersharmony]

Just left to right.

[heathersharmony]

I see the confusion. The images will have the stripes vertical not horizontal as in the owl image. It should be vertical as in the apple image I posted .....sorry about that.

it seems to be working but I am confused as to why my first few folds say page zero.  I will attach the image I used and the pixelcounter result.  Is it possible to have the first column be page # and second and third columns be the fold# like this:  Page 1         Fold 1

                                                                                      1                        2

                                                                                       1                        3

 This way when you have three folds to be cut on page 1 it would be easier to make sense of.                                                                                       

 

 

It wouldnt let me attach the csv file to show you.
