SlideMagic Blog

This tweet exactly applies to SlideMagic:

SlideMagic had a few glitches, but unlike established software products, users that suffered got the CEO himself to add designs to the template bank, recover presentations, gave refunds after people claimed they ‘never intended to make that purchase’, deploy patches within a few hours, and say ‘thank you’ even in the very few cases where feedback was not worded that nicely.

I think SlideMagic is getting close to the finish line as a proper and robust product as I am using it intensely myself now. Thank you all for your patience.

Things are a bit quiet here on the blog, as I am using my annual blogging summer holiday to cleanup SlideMagic further. New features are frozen for the moment, as I am 100% focussed on making the app as stable as possible and have been posting regular updates frequently. If you are a frequent user of SlideMagic, you should now be running version 2.4.28.

One visible change I have made in the latest version is a slightly larger image zoom slider, you can see it in the screen shot below. I rotated the slider, it now appears vertically, allowing me to give it more space and make image zooming more precise.

Updates should install automatically eventually but you can force an update by downloading the latest version of SlideMagic manually.

SlideMagic can switch back and forth between multiple layouts, and needs to handle rapid changes in the grid of a slide. As a result, aspect ratios of images get changed all the time, tripping up your carefully selected image composition. At the moment, the app is storing different crop and zoom levels for different aspect ratios, but that solution is not ideal. (You see how Squarespace gets it wrong with the banner image of this blog post).

I want to get to the point where a SlideMagic user can click a focal point of an image, after which the app will do the hard work of re-adjusting the crop automatically. Doing research, I see a lot of “AI” applications that can figure out what the focal point of an image should be, there seems to be nothing that deals with focal point-based cropping itself. The solutions I see, are ones where you can store multiple crops of the same image, after which the most appropriate one gets selected.

I started scribbling a manual algorithm to come up with reasonable compositions. Here are the first (manual but automateable) results applied to some cows on a beach in Africa, the first image is the original.

It works pretty well, on the the extremely horizontal one gets cropped too low, I would have shown a bit more sky on that one. Let’s see if we can get this to work, both in terms of the algorithm, and the user interface.

Not enough SlideMagic users have discovered that I try to respond to requests for new or missing templates. Today I added a template for an OKR sheet, Google’s approach to managing Objectives and Key Results.

SlideMagic is particularly useful for slides like this, it is easy to add rows, adjust the layout, and now those boring percentages can be visualised easy with a bar chart that always lines up with your table.

Search for “OKR” in the SlideMagic desktop app and it will pop up and ready to work on for free, alternatively, pro subscribers can download the template (in .magic or .pptx format) from the online template bank.

Let me know if you need more/different types of OKR templates.

Thelatest version of SlideMagic has the new arrow feature available, finally enabling me to discontinue the dreaded connectors. Arrows are big and bold to show cause-effect relationships or other forces. I made an algorithm to let them do the right thing in terms of layout in various box sizes, and in various aspect ratios, both for horizontal and vertical shapes. In PowerPoint and Keynote it is fiddly to get arrows to look exactly the same once you start changing the angles of the pointer by hand.

When converting to PowerPoint (a pro feature), your arrows will show up as editable PowerPoint arrow shapes.

I can now call SlideMagic 99% feature complete (hmm, line charts?) and will focus on hardening the application to make it absolutely stable.

The legacy connector feature will stay in the background. If you load an old slide that uses it, the legacy arrows will be rendered and you can edit them. If you have to add more legacy connectors, simply shift-click on the connector icon, and you will be given the option to use the old feature.

The new arrows also give me more design freedom to start expanding the template library with new slide layouts that features these ‘fat’ arrows.

Fat arrows are great for showing cause-effect relationships

Arrows follow the color scheme of the cell, black on accent, will give you this result

I am replacing the connectors in SlideMagic with 2 features. The relatively thin lines that connect boxes in a diagram went live yesterday. Currently I am working on the 2nd feature: fat arrows to show cause-effect relationships or other forces.

As I already discussed back in 2017, it is tricky to get arrows to look right in presentation software. The aspect ratio of the containing box, the angles of the arrow, some come out great, others won’t.

And even if you got one right on your slide by moving the various sliders in the shape, how do you make sure that the 3 below it look exactly the same? Oh, and then you need to insert a fifth one and squeeze everything a bit…

I think I am on to a possible solution. I scribbled an algorithm on a piece of paper, now let’s see how to bring it to life in SlideMagic, and then convert them to PowerPoint. The latter might have to be via an image rather than a dynamic shape. Below is a screenshot of my development machine. Work in progress.

I just deployed version 2.4.16 on the server that has the first version of the new line drawing engine of SlideMagic built in. This will be the replacement of the cumbersome ‘connector’ feature that was inherited from SlideMagic 1.0.

Any presentation app needs some sort of approach to drawing lines, especially to connect boxes in diagrams. Freehand drawing and line dragging goes straight against the philosophy of SlideMagic, which forces you to keep everything lined up, evenly spaced out on a grid.

The connectors solved this by micromanaging lines, you have designate a box to be a line box, and then meticulously set the line configuration inside it. The result is a line grid that perfectly scales up and down with your grid. But this can be a pain to maintain, especially if you are working in a very fine grid.

So I can came up with a compromise and added a separate line drawing layer to the ‘frame; of the slide, the background that sits behind the work area of the slide (i.e., not the title and the footnote). Selecting the frame will highlight a Manhattan-like grid of dots, between which you can draw any (straight) line or arrow you want, across the entire slide. This line patter will move with changes to the grid, but - and this is the concession - is not 100% tied to the boxes in your chart. But I think it is a price well worth paying, imperfections are easy to fix.

A side effect, it is now also easy to draw a fat border around a group of boxes if needed.

SlideMagic 2.0 is almost getting to a point where I can call it ‘feature complete’. Once reached, I will be spending most of my time on hardening the application to make it 100% enterprise-grade, before venturing into adding more capabilities.

The last obstacle on the road are the ‘connectors’, a left over from the SlideMagic 1.0 UI that are not very intuitive to use. The connectors where meant to cover the 2 minimal line drawing elements that any presentation app needs to have:

• The ability to connect boxes in diagrams (flow charts, org charts) with lines and arrows
• The ability to create a visual flow in a slide with big arrows that show cause and effect

This is very tricky to accomplish in SlideMagic, as the app stubbornly insists on not requiring any freehand drawing or dragging that breaks the slide’s grid, and the current ‘connectors’ make that tension perfectly clear.

I think I might have come up with an elegant solution to this problem:

1. Simplify the current ‘connectors’ and use them solely for fat/big cause effect arrows
2. Add a simple grid based drawing capability for connecting boxes.

I got number 2 to work on my development machine, but it still requires a lot of work to make things intuitive, but the hardest part of the work has been cracked.

Luckily there is an advantage that SlideMagic does not have millions of users yet, we can still wiggle the software to get product/market fit, something almost all presentation design apps have failed to reach. Work in progress.

I have entered my usual summer blogger schedule (fewer posts) and am now working really hard to get SlideMagic 2.0 right. The feature list for SlideMagic 2.0 is now almost completely implemented. In software, there are always more things to add, but the product as it stands at the moment is starting to get very useful. Over the last 2 weeks I put in very big changes that might not look big from a user’s perspective, but required huge changes under the hood:

• The new '“side title” layout (my preferred)
• Slide search previews in your own preferred colour, layout, font style
• Horizontal and vertical waterfall charts
• Dynamically generated slides with a relevant image (i.e., unlimited slide in the template bank)
• Better rendering of slides and images on higher resolution screens
• Useful image compression in the background

The only big one that remains outstanding is a better way to make diagrams with lines and arrows, the connector solution is not perfect.

In the background I am now tweaking lots of user interface details: how borders fit around thumbs, mouse behaviour when hovering over things, an “endless scroll” is now working for image search, messages that warn you when things go wrong, or when your app is busy searching, making sure that thumbnails distribute nicely over the screen when zooming, minimising the times when the app needs to re-render a slide or image to make the workflow calmer, etc. etc.

I start to look at app design the way I look at slide design. Things need to be absolutely right, and even tiny deviations, irregularities, small mistakes, can really upset me, while most people won’t even notice them. This is what I think ultimately leads to good design, one by one, these details do not matter, I you add them all though, something works without you having an ability to point your finger at exactly why.

Another day, another improvement

I stuck to showing images on slide search results in black and white because I would be sure that the photos would not clash with the accent colour for the slide users had picked (most users will swap SlideMagic blue for their own logo colour). That worked, but it came at a price: slide templates all looked a bit sad. This is not only due to the greyscale colours, but also because of the way the greyscale filter was applied: many colours were translated into too dark tints of grey I think.

This morning I re-rendered the entire slide database (the server is still a bit tired) and images in slide templates now show up in colour.

It is worth the trade-off I think. Of course it is possible to go back to a black and white image in the SlideMagic app, simple untick the ‘colour’ box and the image will show up as grey scale (you can always go back to colour if you want).

The colour option is only available for the slides that I added more recently, after I switched off the colour option when ‘flattening’ or compressing slides. Obviously new templates will all appear in colour, or I will set them explicitly to black and white when I feel that it serves the slide’s message better.

This addition of colour coincides nicely with the more mature SlideMagic product I think, slowly but certainly it comes out in its full shiny colours :-)
