Page layout bitmap size wrong in modern/GAL canvases

[Michael Kavanagh]

My page layout file has 3 bitmaps (logos). These were scaled down by adjusting the DPI in the page layout editor (weird as I now cant find that option ), since it improved display when zooming in on plotted PDFs.

These display fine in the legacy canvas in Eeschema and Pcbnew but appear massive in the modern canvases.

I can send the files if it'd help but would rather not upload them online.

(Actually running Windows 10 despite what it says below).

Hi Michael,

Please send me the files exhibiting the problem. I am in process of fixing bitmap scaling in printouts, so this might be related.

Hi Orson,

Bitmap images have a scaling factor (the PPI is set to 300, and the actual drawing size is size_for_300_ppi * scaling factor)
For instance, if in page layout editor you set the ppi to 100, the scaling factor is 3.0

Unfortunately, when I added the draw bitmap function in GAL, I forgot to take in account this scaling factor

I also just saw the recent (5.0) page layout editor the PPI setting is no longer displayed, due to and issue in the .fbp file.
(But works in 4.0 version)

I'll commit a fix very soon for the page layout editor issues.
