Figure 4. Images Layout Options
•The Layout Rules determine the layout of images as defined in the Columns and Rows boxes. The Space between Columns and Space between Rows boxes determine the empty space between columns and rows of images.
•The options in the Align Images section determine the alignment of images:
•There are two options in the Fit dropdown menu:
•Reduce to Cell reduces images to fit the dimensions of the PDF document. If images are smaller than the PDF document then they will remain at their original size.
•Fit to Cell fits images to the dimensions of the PDF document. If images are smaller than the PDF document then they will be increased in size.
•The Keep Aspect Ratio check box is selected by default, which means images retain their proportions and fit the specified dimensions as far as possible within those proportions. Clear the check box to disable aspect ratio. Images will then match the specified dimensions but they may distort as a result.
•The Horizontal/Vertical Alignment dropdown menus determine the location at which images appear in the new document.
These settings can be used to add labels to converted images:
Figure 5. Image Labels Options
•Select the Use special text label for each image check box to enable further options.
•Enter the label text into the text box. Click the blue icon to add macros.

•Select the Add bookmark for each image with the same text as label option as desired.
These settings determine Image Processing options:
Figure 6. Image Processing Options
There are two options for True Color, Grayscale, Indexed and Monochrome images:
•Downsampling reduces the sampling rate of images. Each format has three options: Linear, Bilinear and Bicubic. Further information about these options is available here. The pixels per inch boxes are used to set the size above which images will be downsampled and the size to which they will downsampled.
•Conversion relates to the automatic conversion of files, where possible, from one format to another. Use this option to convert the format of new files when they are created. Select the boxes for dithering as desired.
These settings determine compression options:
Figure 7. Image Compression Options
•Clear the Compression enabled boxes to disable compression for the formats indicated.
•When compression is enabled, use the adjacent menu to select the type of compression that the tool will carry out. Auto is the default setting.
•Where applicable, adjust the JPEG Quality/JBIG2 Method and Lossless options as desired.
These settings determine post-processing options for images:
