A bitmap image can be inserted in LibreOffice Writer, LibreOffice Calc, LibreOffice Draw and LibreOffice Impress documents.
Choose Insert - Image.
Select the file. In the File type box you can restrict the selection to certain file types.
Click the Link box if you want a link to the original file.
If the Link box is marked, whenever the document is updated and loaded the bitmap image is reloaded. The editing steps that you have carried out in the local copy of the image in the document are re-applied and the image is displayed.
If the Link box is not marked, you are always working with the copy created when the graphic was first inserted.
To embed graphics that were first inserted as links, go to Edit - Links and click the Break Link button.
Click Open to insert the image.
When you select the bitmap image, the Image Bar offers you the tools for editing the image. Only a local copy is edited in the document, even if you have inserted an image as a link.
The Image Bar may look slightly different depending to the module you are using.
A number of filters are located on the Image Filter toolbar, which you can open with the icon on the Image Bar.
The original picture file will not be changed by the filters. Filters are applied to a picture only inside the document.
Some of the filters open a dialogue, which you can use to select, for example, the intensity of the filter. Most filters can be applied multiple times to increase the filter effect.
In LibreOffice Draw and LibreOffice Impress, you can add text and graphics, select these objects together with the bitmap, and export the selection as a new bitmap image.
Right-click the picture and choose Picture from the submenu to open a properties dialogue.
Change the properties of the selected picture, then click OK.
If you want to save in a format such as GIF, JPEG or TIFF, you must select and export the bitmap image.
To export a bitmap in Draw or Impress:
Select the bitmap image. You can also select additional objects, such as text, to be exported with the image by pressing the shift key while selecting or by opening a selection frame around all objects.
Choose File - Export. The Export dialogue opens.
The Export command writes the picture with all applied filter effects to a file. The Save as Picture command in the context menu saves the picture without any filter effects, if the picture was inserted as a linked picture. An embedded picture will always be saved or exported with filters applied.
In the File format field, select the file format you want, for example GIF or JPEG.
If you only want to export the selected objects, mark the Selection box.
If Selection is not marked, the entire page of the document is exported.
Enter a name for the file and click Export.
To export a bitmap in Writer: Right-click the bitmap, choose Save Graphics. You see the Graphics Export dialogue. Enter a file name and select a file type.
