#+TITLE: QA 09 — Images
#+TODO: TODO | PASS FAIL SKIP

* How to run
  : emacs --no-init-file -l qa/09-images/test.el
  : EMACS_GPU_DISABLE=1 emacs --no-init-file -l qa/09-images/test.el

  The test uses Emacs built-in images from =data-directory=.
  For JPEG and external SVG tests, provide paths to your own files when prompted.

* Checklist

** TODO 9.1 PNG opaque — correct colors, sharp edges
   The built-in PNG icons must appear with correct colors and sharp edges.
   Failure: washed out colors, blurry edges, or image not displayed.

** TODO 9.2 PNG with alpha channel — background shows through
   The icons with transparency must composite correctly against the
   Emacs background; the fringe/frame background must be visible through
   transparent areas.
   Failure: transparent areas appear as white or black rectangles.

** TODO 9.3 SVG — sharp at any scale
   The built-in SVG must appear crisp with no pixelation.
   Failure: blocky rendering, or SVG shown as a broken-image placeholder.

** TODO 9.4 Image with :scale 2.0 — visibly larger
   The scaled version must be exactly twice the size of the original.
   Failure: both images appear the same size.

** TODO 9.5 Image with :rotation 90 — correctly rotated
   The rotated image must appear turned 90° clockwise.
   Failure: image appears unrotated, or is blank.

** TODO 9.6 Image slice — only specified portion visible
   Only the top-left 32×32 pixels of the source image must be shown.
   Failure: the full image is shown, or the wrong quadrant.

** TODO 9.7 Image with :relief — raised border around it
   A raised-relief border must be visible around the image.
   Failure: no border, or border has wrong colors (sunken instead of raised).

** TODO 9.8 Image cache — two insertions identical
   The same image inserted twice must look identical in both places.
   Failure: second insertion looks different (wrong colors, size, or missing).

** TODO 9.9 Image adjacent to text — correct vertical alignment
   Images must align with the text baseline; they must not shift the
   surrounding line height excessively.
   Failure: large gap above or below the image, or text and image overlap.
