Image processing apparatus capable of converting image file such that all annotation information can be used, control method therefor, and storage medium

A control method for controlling an image processing apparatus, the control method comprising:

• converting a first-format image file including image data and annotation information on the image data to a second-format image file, whose memory capacity of a predetermined area where annotation information is recorded, is less than that of the first-format image file;
• and,
• in a case when the annotation information included in the first-format image file is not predetermined annotation information, whose data amount is equal to or greater than a predetermined value, recording the annotation information included in the first-format image file into the predetermined area in the second-format image file, and, in a case when the annotation information included in the first-format image file is the predetermined annotation information, recording link information on the annotation information included in the first-format image file into the predetermined area in the second-format image file.

A non-transitory storage medium storing a computer-executable program for causing a control method for an image processing apparatus, the control method comprising:

• converting a first-format image file including image data and annotation information on the image data to a second-format image file, whose memory capacity of a predetermined area where annotation information is recorded, is less than that of the first-format image file;
• and,
• in a case when the annotation information included in the first-format image file is not predetermined annotation information, whose data amount is equal to or greater than a predetermined value, recording the annotation information included in the first-format image file into the predetermined area in the second-format image file, and, in a case when the annotation information included in the first-format image file is the predetermined annotation information, recording link information on the annotation information included in the first-format image file into the predetermined area in the second-format image file.
