Sample data and unit tests

[s-celles]

Hello,

It will be great if this project could provide sample data
and use these data as unit tests.

Kind regards

The sample data is available in the tutorial which I'm hosting on thregr.org, but unfortunately I couldn't get permission to upload it to github.

I haven't found also Gimp template file and exported file template-it.png
Being able to download marks-it.svg could help to follow tutorial more quickly

This is intentional. The files provided are just the scans, which is exactly what you have when you start from scratch. Generating all the required files, and doing them properly, is the most important aspect of the tutorial. It's not intended to be a short step-by-step overview.

ok
I have a large form with 25 rows and 5 columns ie 125 questions with 1 possible answer out of 4 ie 4 check boxes (A, B, C, D).
Do you have a script to generate such svg file?
Such script could accept the following parameters

• png template file
• box_width
• box_height
• offset_x
• offset_y
• space_x
• space_y
• rows
• columns
  This script will output svg file that could them be edited using Inkscape for adjustments
  If you don't have such a script I will try to create one using yattag http://www.yattag.org or svgwrite https://svgwrite.readthedocs.io/

No, but creating the template with Inkscape is still pretty fast. Create one rectangle, duplicate it 4 times then assign some template names, then group, then duplicate it 25 times. Move one down, then "distribute vertically". Generating such grids is pretty quick. Naming them is the slow part, as I'm not aware of a quick way to do this using Inkscape. In my case, I saved the SVG, did a quick sed script to rename the values and reloaded it into inkscape for checking.

Under Mac OS X and Inkscape 0.92.2, when I copy a rectangle it pastes as image

  <rect
     style="opacity:0.7;fill:#ffb534;fill-opacity:1;fill-rule:evenodd;stroke:#000000;stroke-width:1px;stroke-linecap:butt;stroke-linejoin:miter;stroke-opacity:1"
     id="q4_no"
     width="62"
     height="62"
     x="240"
     y="436" />
  <image
     y="145.87442"
     x="121.4196"

You have to use "duplicate" (Ctrl+D).

Thanks for the tip.

Here is my code to create a SVG template with many aligned checkboxes from a png file:

#!/usr/bin/env python

import click
import os
import svgwrite
import base64
from PIL import Image


@click.command()
@click.option('--img', default='', help='Image filename')
@click.option('--box-width', default=28.1, help='')
@click.option('--box-height', default=22.6, help='')
@click.option('--offset-x', default=29, help='')
@click.option('--offset-y', default=22, help='')
@click.option('--space-x', default=0, help='')
@click.option('--space-y', default=0, help='')
@click.option('--space-columns', default=143, help='')
@click.option('--rows', default=20, help='')
@click.option('--answers', default=4, help='')
@click.option('--columns', default=5, help='')
@click.option('--color', default='#ffb534', help='')
@click.option('--opacity', default=0.7, help='')
@click.option('--stroke', default='#000000', help='')
@click.option('--stroke-width', default='1px', help='')
def main(img, 
         box_width, box_height, 
         offset_x, offset_y, 
         space_x, space_y, space_columns,
         rows, answers, columns,
         color, opacity,
         stroke, stroke_width):
    if space_x == 0:
        space_x = box_width
    if space_y == 0:
        space_y = box_height
    # if space_columns == 0:
    #     space_columns = 10
     
    if img != '':
        (img_root, img_ext) = os.path.splitext(img)
        allowed_ext = ['.png']
        if img_ext not in allowed_ext:
            raise NotImplementedError("File extension %r not supported" % img_ext)
        filename_out = img_root + '.svg'
    else:
        filename_out = 'marks.svg'

    dwg = svgwrite.Drawing(filename_out, profile='tiny')

        im.close()
        data = "data:image/png;base64,%s" % encoded_string.decode('ascii')
        dwg.add(dwg.image(data, id='image', x=0, y=0, preserveAspectRatio="none", width=im.width, height=im.height))
    
    offset_x_for_col = offset_x
    pos_x, pos_y = offset_x, offset_y
    for column in range(1, columns + 1):
        print("Column: %d" % column)
        for row in range(1, rows + 1):
            print("  Row: %d" % row)
            for answer in range(1, answers + 1):
                id = "q_%02d_%02d_%02d" % (column, row, answer)
                print("     Answer: %d - %s" % (answer, id))
                dwg.add(dwg.rect(insert=(pos_x, pos_y), size=(box_width, box_height),
                    fill=color, opacity=opacity, id=id,
                    stroke=stroke, stroke_width=stroke_width)
                )
                pos_x = pos_x + space_x
            pos_x = offset_x_for_col
            pos_y = pos_y + space_y
        pos_y = offset_y
        pos_x += space_columns
        offset_x_for_col = pos_x

    print("Save to %r" % filename_out)
    dwg.save()


if __name__ == '__main__':
    main()

Were you able to get going?

I don't know if this would be possible, but if you have the chance to share some of the pages to add to the sample data would be nice.
