Just when we thought the pandemic was coming to an end, another variant appears to scupper our plans. So, resuming in-person events is delayed, and the world isn’t safe until the world is immunised. Therefore, I decided to make the presentations that I was going to be presenting on the abandoned Microsoft Ignite The Tour last year available, although I did manage to go to London and Copenhagen before we all stopped flying around the globe…[Read more…] about Visio Presentations for the Microsoft Ignite The Tour 2020
I was pleased to present two sessions at London ExCel last week about Visio. Attendance was good, maybe too good because some could not get close enough to hear. There was a lot of background noise, and my presentations were too long for the 15 minutes slot, but content was eagerly received.
I told everyone to download the slide decks, but I cannot find the link on the TechCommunity pages yet, so I have created my own links ….[Read more…] about My sessions at MS Ignite the Tour 2020 London
The Web Content Access Guidelines (WCAG) 2.0 provides the current recommendations for making web content accessible to users with vision impairment, but how do you test if your Visio shapes pass? There are several web sites out there that provide this capability, but all of them require the HEX values, rather than the RGB or HSL that Visio provides natively. Therefore, I have created a Visio callout shape that can be associated with a target shape to report on the values of each of its main color elements, and provides hyperlinks to automatically check the contrast ratio on WebAIM.

The colour formats that can be selected from either the Shape Data window or the right mouse menu are:
One of the ways that Visio supports accessibility is to provide text that is read out by a screen reader, such as Windows Narrator or JAWS. This Alt Text can be set using Format Shape / Size & Properties tab using the Title and Description text boxes. The Title is the initial text that is read out when a shape is attentioned, and the Description will only read out if the user pauses. The Description text box only allows 255 characters to be entered and displayed, but this is not actually the limit![Read more…] about Narrated Text in Visio for Accessibility
Visio defaults to tabbing from shape to shape in the order that the shapes are added to the page. However, this can end up with an illogical order if you are trying to navigate a diagram with the keyboard, which is often an accessibility requirement. Fortunately, Visio provides a Diagram Navigation pane so that the tab order can be changed, but how does it do it? The following short video shows how the navigation order, displayed as numbers in each shape, is assigned a value as soon as the order is edited.

I managed this by adding a User.visNavOrder to the master shape of all the significant masters, and a hidden Shape Data row, labelled “Navigation Order“. This has the following formula for its value:
