Dave posted: 14 Sep 2017 00:44 from: Martin Wynne If you have tried adding map screenshots you may have noticed that they vanish while zooming in on them, until you zoom back out. Usually at the least convenient moment while closely aligning a template over them. This is system and graphics chip/card dependent and caused by memory limitations in the Windows GDI StretchDraw function. To prevent this happening, for 215b I have added an automatic conversion to 24-bit colour on loading the map screenshots. This significantly reduces the memory requirement by removing the alpha channel. That is used in graphics editor programs, but serves no purpose in Templot. There is no visible effect on the image on the trackpad. This should also make for faster rendering and panning on the trackpad.

It can be zoomed using the slider, or the mouse wheel. Alternatively for an accurate preview of every printed dot, you can lock the zoom at dot-for-dot by ticking the tickbox: 2_171802_240000001.png Which as you can see is very large image in screen terms, and will need a lot of scrolling to see all of it. Untick the box to revert ...
