Gulrajas How to concatenate 2 images — ImageMagick If you open the image file, and then print it to file, does it let you combine those files? Whatever might have appeared in the remainder of A, above that point, will be cropped. I just saw that you have many files to process, you can use print-selected script in Nautilus described here. Post was not sent — check your email addresses! In that case, the source suggested it might instead be the magick. Officially, I was supposed to reboot the system to fully update the path change.

It will only fill the space row by row, no option is currently provided to do a column-by-column fill of the tile space. Before IM v6. As such a setting such as the first "9x1" image would have been truncated to produce a "7x1" tile image.
Because of this, past users of montage often used large numbers such as "x1" to generate a single row of images. Now such a argument will produce a very long image, and could take a long time for IM to complete. As such Avoid the use of very large tile numbers in IM montage! You can avoid the problems of extra space, and multiple images, especially for an unknown number of input images, by removing either a row, or the column number, from the " -tile " setting.
The missing number will be taken by montage as being variable and montage will only create enough tile space to hold ALL the input images, producing only one image, never multiple images. Note the last image, in the above where we requested 9 columns of images. IM still generated the requested 9 columns, even though less than 9 images were given.
On the other hand the first image one row requested , is exactly the right length to hold all the images. If you have more input images than montage can tile into the space given by a " -tile " setting, then multiple images can be generated by montage, either resulting in image sequence numbers being added to the filename, or some sort of GIF animation, being created. See Writing Multiple Images for details.
For example, you can better define the images being displayed by adding a " -frame " around each image. The montage frame option will automatically figure out default values for the internal and external bevel of the frame. As such only a single argument number is needed. Border Decoration Sometime around IM v6. That is border would have been thus added to the image long before the images get resized according to " -geometry " , which resulted in different border widths around each image depending on the size of the image at that point.
It was to remove this inconsistancy that -border became a special montage setting. Shadow Decoration Adding a shadow with the frame is also quite good. This means if you create a montage with textured background, or use a transparent background and overlay it, the shadow will do the right thing. Of course you need to use an image format that can handle semi-transparent colors, like PNG.
Note that shadows do not care about the " -geometry " spacing between the images. As such if the images are too close together, the shadow of previous images can be obscured by later images. For example This is on top of the normal " -geometry " spacing provided. However as you can see above, this is not always enough space. Labeling Montage Images You can also tell montage to label the image with their source filenames, though you probably need to resize the image frames, or the labels may not fit, truncating the text label.
This is probably the most typical use of montage. See Image Property Escapes for details of other information you can extract from images. The labels are not shadowed, so that they remain clearly readable. Lets use the " -set " operator to add more information about the images.
And also few more montage settings If the image size was modified, such as during input this may be different to the images in disk or creation size. You can also label images differently by setting label of individual images.
Either option can be used, though you will need to use of parenthesis to limit what images the " -set " operator will be applied to.
Here for example we use both forms of labeling. But lets also add a title to the montage, just because we can However as you will see later these two settings are not quite the same.
The same applies for a post reading, label " -set " operation. This presents a good rule of thumb when using montage Either label all your images, or none of them! Montage will automatically label any image read in that already contains a label. This is automatic and does not need to be specified, and I have used this technique to generate some very complex image montages. For example the montage array in Annotate Angle Examples was created using this technique. The former will reset the default behavior back to automatically using any label meta-data that the image being read-in may have , while the later replaces the label with an empty string, which effectiavvly removes the label.
Using Saved Image MetaData When generating images for later use by montage it is important to know what sort of image metadata a specific image file format can save.
The GIMP program particularly likes to add such comments and labels, unless you tell it not to, every time you save an image. Instead they are usually added by some other method in order to avoid reading and re-writing the image data and thereby degrading the JPEG image files in which you are adding comments.
Montage just makes automatic use of image labels if present. Labels and comments are attached to images, and the their specific file formats, and is not montage or even IM specific. The "null:" generated image was defined specifically for this purpose.
The tile is just left completely empty except for the background color or texture of the montage drawing canvas itself. There is no method, at this time to allow montaged images to span multiple rows or columns, as you can in HTML tables. Nor can you generate variable sized rows and columns to best fit the array of images being generated. If you really need this sort of ability you will need to develop your own montage type of application.
Some solutions for this includes labeling and framing the image thumbnails yourself and then using either Append Images or use a more free form Layering Image technique.
