S_Merge V1.6 FAQ's

Bug report at the end of this page

Question Answer
I wish to surround my target image with my favorite border from another image? In the Align Window ensure that the border image is the largest and surrounds the other images. In the Target Window click and within the merge box, set the border source image to the bottom layer.
What is the back ground color of the base? There is an option in the target menu to set this color.
Can I set a margin and its color around all images before saving? Yes you can set width and height and color of margins.
I need to change something; can I realign the images after blending them in the Target Window? Yes you can by going back to the Align Window. This action will invalidate the image in the target window. S_Merge will remind you to update it.
Can the source images can be placed anywhere, be any size and rotation? Yes, they can be placed next to each other, one on top or completely or partially overlaid. They don't even have to touch as a minimum; there can be a gap in between.
How many image formats can S_Merge handle? File types when opening a source or saving the target are: bmp, jpeg, png, tiff, tga, and pcx .
Can I merge an image with itself in a different position? Simply send the target back to a new source and position what are now two images in the Align Window. Try mirroring one of the images.
I just wish to align some images side by side, save them and nothing else. Load them in the Align Window and select collaging. Arrange them as you wish then switch to the target window and press 'Generate Target'.
Why is it possible to load images from the Align window, Target window and any Source window? S_Merge allows loading of images at any of the main windows, but they always end up as a new source window. After loading S_Merge always switches to the Align Window for positioning.
How do you smoothly merge part of an image (say source 1) into the middle of another image? (source 2) In source 1 set the entire image to transparent by clicking . Also in source 1 set a zone box around the area to be smoothly merged then click the smooth blend button that appears. In the Target Window, click and in the merge dialog box click "Blend all to middle layer" and then set the bias on the pie strongly towards source 1.
Some sections of a grid disappear when viewing from the Align Window or the Target Window, why is this? The Align Window image is usually smaller than the real life images to be saved in the target. Line thickness of grids that are below a certain value will not be visible or possibly artefacts maybe present. In the target window the grid will be visible if the target is scaled to 100% and S_Merge will use anti-aliasing techniques even when the image is rotated. This naturally applies to saved images from the target as well.
Sending a Target Window to a new source does not allow changes (such as rotating in the Align Window) to any of the original source images within that new source? The new source generated now has to be regarded as one image only; you cannot get access to the original ingredient source images. You can however manipulate this new source image as you would any other source.
Reference that last question; I have generated an 8-source collage with internal gaps that I want filled with a new background image. I sent this collage from the target to source 1, deleted the other sources, and loaded a new background image (source 2). If this complete collage is now just one image, how do I get the new source 2 to be the background? Always ensure that the intergap color is set to a dummy color that is not used in any of the images, such as black or white, before you send to source 1. Now in this source 1 click and set the color that you chose for the intergaps to be transparent. Switch to the target click and put source 2 to the bottom layer. If you discover that some of the intergap color is present in the source 1 image then put a zone over it and make it opaque.
I have applied some chroma keying to an image and there are no other sources. Why can I not see any effect in the target? The target derived from a single source will be fully displayed even if some areas have been made very transparent. This is the default situation but can be adjusted differently using the low tide option in the target menu. Try setting the value to maximum and transparent areas will be replaced (smoothly) with the background color of your choice.
I loaded an image into S_Merge but it is incorrectly rotated by 90 degrees. S_Merge does not take account of any EXIF information and you can correct this by invoking the rotate command.
Why is S_Merge complaining about shortage of memory? S_Merge with its multiple image handling will use a lot of memory. With 4 GB of computer ram it can manage up to 4k X 3K pixel target images but this figure is very dependent on source image real estate. The 64 bit version of S_Merge can handle far larger images and run faster. Watch the predicted target size at the bottom of the screen. Use vigilance when setting up collages, S_Merge predicts and loads the maximum size that can be used for each source. It is not recommended to exceed these values.
Is it possible to remove perspective distortion already present in an image? No but you can try using perspective distortion "in the opposite direction" that will partially correct the problem. Attempting this will cause a parabolic (x^2) distortion or bulge in the center of the image. This is not a bug.
I am trying to page number a bunch of images with text using the special sequence >n< mentioned in the documentation. Problem is the ordering is not quite correct. S_Merge sorts files according to the NTFS format and not to explorer format.

Check this article for more info:https://blogs.msdn.microsoft.com/oldnewthing/20050617-10/?p=35293

Renaming files by adding a count suffix to the file name can be helpful in this case.

A future issue of S_Merge may address this anomaly.

S_Merge V1.6 bug report

Bug Description
When invoking Batch processing where one or more sources have been cropped, the zone commands sometimes appear truncated.

The following bug is only present when batch processing /merging.

Using one of the four zone commands (smooth blend/unblend/opaque/transparent) after a crop in the pre-processing command sequence is supposed to use as a reference; the dimensions of the image after a crop has taken place. S_Merge incorrectly uses the pre-crop dimensions resulting in chopped areas of a smooth blend.

If the crop is invoked after a zone command there is no problem. Version 1.7 will fix this issue.

Cannot reload a source file from the MRU after a batch process/merge session.

S_Merge incorrectly assumes the file is still open despite it being replaced by other files during batch processing. This prevents reloading and the next version should correct this issue.
