View source on GitHub. In Part 1 of this series, I discussed the problem of displaying different bitmap images at different DPIs in WPF. In Part 2, I proposed a solution using multi-frame TIFFs and two simple markup extensions. In this final post I will present a basic program that takes multiple images (PNG recommended),… Continue reading Pixel-perfect Multi-DPI Images in WPF (Part 3)
View source on GitHub. See also: Part 1 and Part 3. In Part 1 of this series, I explored the issue of displaying pixel-perfect bitmap images in the Windows Presentation Foundation. In this article, I’ll describe a method of displaying different images depending on the system DPI setting using a custom Markup Extension and multi-image… Continue reading Pixel-perfect Multi-DPI Images in WPF (Part 2)
View source on GitHub. See also: Part 2 and Part 3. I’ve written previously about DPI-awareness in the Windows Presentation Foundation and how to specify measurements in pixels rather than Device Independent Units (DIUs). Something else to consider is image scaling – unlike the Windows Ribbon control or WinRT, WPF has no in-built mechanism for… Continue reading Pixel-perfect Multi-DPI Images in WPF (Part 1)
Today I released an update to the VCE Study Score Archive: scaling data for 1998 and 2000-2004 is now included (I hadn’t realised that the scaling reports were available on the VTAC website). Download the updated files here. Note that the 2010 data has not been modified.
Part of the beauty of the Windows Presentation Foundation is that it is designed to be resolution independent – that is, a WPF application should scale perfectly no matter the system’s DPI setting (excluding any bitmap graphics, which mightn’t look as nice as the vector parts). Instead of measuring things in pixels, WPF uses Device… Continue reading Pixel Measurements in WPF
As I previously mentioned, this year’s release of the Study Score Archive will feature estimated scaled scores alongside raw scores. Helpfully, VTAC provides scaling data in the annual Scaling Report, but correspondences between raw scores and scaled scores for each subject are provided only for scores that are greater than 20 and are multiples of… Continue reading Scaled Study Score Interpolation in the Study Score Archive
The number of years since I finished VCE continues to increase, but I still plan to publish my Study Score Archive once results are released in the near future. There will be one major additional feature this year: scaling of scores. Newspapers only publish raw scores, which can be misleading: a raw score of 40… Continue reading VCE Study Score Archive: Improvements for 2010
