Type Alias: ImageSizer

type ImageSizer = (src: string) => 
  | {
  h: number;
  w: number;
}
  | null;

Defined in: common/htmltable-types.ts:90

Callback for resolving image dimensions in HTML labels.

Returns the intrinsic {w, h} in points for src, or null when the image cannot be resolved. Absent or null → zero-size cell + warning, matching C's missing-image behavior (htmltable.c:size_html_img, gvusershape.c).

AD3 (locked): absent ImageSizer must be indistinguishable from C-with-missing-file.

Parameters

src

string

Returns

| { h: number; w: number; } | null
