odiffr (version 0.5.1)

compare_dirs_report: Compare Directories and Generate HTML Report

Description

Convenience function that compares all images in two directories and generates an HTML report in one step.

Usage

compare_dirs_report(
  baseline_dir,
  current_dir,
  diff_dir = "diffs",
  output_file = file.path(diff_dir, "report.html"),
  parallel = FALSE,
  title = "odiffr Comparison Report",
  embed = FALSE,
  relative_paths = FALSE,
  n_worst = 10,
  show_all = FALSE,
  ...
)

Value

The odiffr_batch results (invisibly). The HTML report is written to output_file as a side effect.

Arguments

baseline_dir

Path to the directory containing baseline images.

current_dir

Path to the directory containing current images to compare against baseline.

diff_dir

Directory to save diff images. If NULL, no diff images are created.

output_file

Path for the HTML report. Defaults to file.path(diff_dir, "report.html").

parallel

Logical; if TRUE, compare images in parallel. See compare_images_batch() for details.

title

Title for the HTML report.

embed

Logical; if TRUE, embed images as base64 data URIs for a self-contained report. If FALSE (default), link to image files.

relative_paths

Logical; if TRUE, use relative paths for images in the HTML report. Makes reports portable without embedding. Ignored when embed = TRUE. Default: FALSE.

n_worst

Number of worst offenders to display in the report.

show_all

Logical; if TRUE, show all comparisons in the report, not just failures.

...

Additional arguments passed to compare_image_dirs() (e.g. threshold, antialiasing, pattern, recursive).

Examples

if (FALSE) {
# One-liner for QA workflow
compare_dirs_report("baseline/", "current/")
# -> Creates diffs/ directory with diff images and report.html

# With parallel processing and embedded images
compare_dirs_report("baseline/", "current/", parallel = TRUE, embed = TRUE)

# Pass comparison options via ...
compare_dirs_report("baseline/", "current/", threshold = 0.1, antialiasing = TRUE)
