![]() Normally this selection process might take a variable amount of time depending, for example, on how carefully one is trying to specify the selection boundary. In the current circumstances one has to consciously complete the selection process before the timer is complete for things to work. Is the delay action ( however many seconds) always timed from the very beginning of the actions rather than the completion of the proceeding action? This does not seem optimal. If I am depressing the Left-Click part of the Mouse, it does not work which I found peculiar because this is not the "usual" way that one specifies screen capture areas. When dragging out the area to specify for the screen capture, I have to depress the Right-Click part of the Magic Mouse. Since it takes some time just to drag out the area that you want to specify, it is easy to use up the 3 seconds before the area specification is complete. Why intermittently? Because it turns out that the 3 second timer starts immediately upon launching the first action and NOT after the first action is completed. That did not work as written so I put a delay (3 seconds). That is what I generally want so I set up an action for a Return Key as the next step in the Action list. Graphic Converter immediately puts up a window asking if you want to retain the alpha channel with the default button Open and Retain. Then I wanted to set things up so the captured area was sent to Graphic Converter. The activation works fine and I get a cross-hair to specify what I want to capture. Save as png or jpg according to your needs.First test experiment that I tried was to do a Capture Screenshot.Choose Image boundaries option from Image menu (Third item from top Cmd + Opt + C) increase the image boundary to the Right in your case by the current width of the image (assuming both images are of same size).Use the Move tool (right most selected button in toolbar in the screenshot) to align your layer to the right of the previous one.Chances are, it will open the format you couldn't open in. It can export anything it can open into one of 80 different formats. Seashore will ask you if you want to create a New Layer or Anchor it with the one already there. GraphicConverter can open about 200 different file types. Copy over the second one into the first one.It supports layers, filters, channels and supports almost all image formats, plus it has better image / layer selection and resizing tools that may be better suited for your image editing needs. It has better tools much on the lines of popular editors (including shortcuts) and I guess if you try you should be doing just fine without much help from us. Speaking of free GUI tools, Seashore app is an open source project much better at working with images than Preview.app. * Keep this as a Template size, with any others, clearly labelled with their dimensions for future use. Menu > File > Save As… > New name > Whatever file format you want You can scale them by dragging their handles, and nudge them a pixel at a time with your cursor keys. Switch to your blank background image, command v (Paste) each in turn dragging them into position next to each other. Select each of your two images in turn and go command a (Select All) and command c (Copy) Double click on this along with your two existing images to open them in Preview. Make a screensnap: command shift 4 > drag out an area 640 x428 Not strictly necessary but makes life easier. Open up any Application that lets you have a clean neat whiteīackground.How to do this with the tools to hand: Preview. I used it on and now the correct code is convert +append a.png b.jpg +append c.tif Alternatively, you could put this in some sort of automator script. This isn't a GUI application, but maybe some others might have a better solution. For example, you can switch to a different image format for the output convert +append a.png b.jpg c.tif With convert, you can do a ton of other things. Alternatively, you append them vertically with -append (instead of +) and a.png will be on top of b.png. To create a new file, c.png, that has the a.png on the left and b.png on the right. If you have your two 320x428 images, say a.png and b.png, you can do convert +append a.png b.png c.png The actual tool you want to use from Imagemagick is the convert tool. You could also choose to install with brew ( brew install imagemagick). I use the command line tools that come in the Imagemagick package I think I installed it on my system with MacPorts. I often have to do this with images of plots of data.
