Cropping & Compressing Images<\/span><\/h2>\n

Open Publisher’s image tools include a non-destructive cropping system and a built-in compression utility, letting you frame your photos perfectly and keep your document file size under control.<\/p>\n

Image Cropping\"Image<\/span><\/h3>\n

The cropping tool lets you non-destructively trim an image to show only the part you want, while keeping the original file intact.<\/p>\n

To crop an image:<\/p>\n

    \n
  1. \n

    Select the image on the canvas.<\/span><\/p>\n<\/li>\n

  2. \n

    In the Picture Tools<\/strong> contextual ribbon, click Crop<\/strong>.<\/span><\/p>\n<\/li>\n

  3. \n

    The element enters crop mode: black crop handles appear at the edges and corners. Drag them inward to set the visible area.<\/span><\/p>\n<\/li>\n

  4. \n

    While in crop mode, you can also click and drag the image itself to pan it within the crop frame – repositioning the content without changing the frame boundaries.<\/span><\/p>\n<\/li>\n

  5. \n

    Click anywhere outside the element (or click the Crop<\/strong> button again) to confirm the crop and exit crop mode.<\/span><\/p>\n<\/li>\n<\/ol>\n

    The crop parameters – frame position, image pan offset, and zoom – are all saved into the element’s data and persist across undo\/redo and save\/load cycles. The print engine honours your exact crop settings and does not reset to the full image during printing.<\/p>\n

    Crop to Shape<\/span><\/h3>\n

    \"Crop<\/h3>\n

    In addition to rectangular cropping, Open Publisher can clip any image to a custom shape. The shape library includes 14 options: circle, star, triangle, heart, diamond, pentagon, hexagon, octagon, cross, arrows, trapezoid, parallelogram, shield,<\/strong> and speech bubble<\/strong>.<\/p>\n

    To apply a shape crop:<\/p>\n

      \n
    1. \n

      Select the image on the canvas.<\/span><\/p>\n<\/li>\n

    2. \n

      In the Picture Tools<\/strong> ribbon, click Shape Crop<\/strong> (or select it from the right-click context menu).<\/span><\/p>\n<\/li>\n

    3. \n

      Choose a shape from the one-click button grid. The interface features a 2-column grid with built-in preview icons – simply click your desired shape to instantly apply the crop and close the dialog.<\/span><\/p>\n<\/li>\n<\/ol>\n

      Note on existing documents: If older documents contain shape crops saved before version 4.13.20, re-apply the shape via Picture Tools > Shape Crop<\/strong> to force the updated data into the file.<\/em><\/p>\n

      Compressing Pictures<\/span><\/h3>\n

      \"CompressingTo reduce the file size of your .opub<\/span> document, use the Compress tool to reduce the embedded size of large image files without significantly affecting their visible quality.<\/p>\n

      To compress a picture:<\/p>\n

        \n
      1. \n

        Select the image on the canvas.<\/span><\/p>\n<\/li>\n

      2. \n

        In the Picture Tools<\/strong> ribbon (or under Adjust<\/strong> in the Insert ribbon), click Compress<\/strong>.<\/span><\/p>\n<\/li>\n

      3. \n

        A modal appears with a live progress bar tracking the estimated size reduction in real time.<\/span><\/p>\n<\/li>\n

      4. \n

        When complete, the image in the document is replaced with the compressed version.<\/span><\/p>\n<\/li>\n<\/ol>\n

        The compression tool includes built-in safeguards:<\/p>\n

          \n
        • \n

          If the image is already fully optimised, a dialog appears explaining it cannot be reduced further – no redundant processing occurs.<\/span><\/p>\n<\/li>\n

        • \n

          If an unsupported element type is selected (such as Clipart, WordArt, or a vector Shape), the tool halts and displays a clear \u201cNot Supported\u201d message rather than failing silently.<\/span><\/p>\n<\/li>\n<\/ul>\n<\/div>\n","protected":false},"excerpt":{"rendered":"
