Font Size in decimals

[martinrame]

Hi, I'm creating a "Print Preview" image using BGRABitmap, and noted FontSize is defined in Integer, this is causing the text doesn't look accurate, compared to the final printed page.

For example, when I zoom to 100% and font is, for example 20, it looks ok. If I zoom out to 20%, font size is, say 4. If I continue zooming out, to 19%, font changes to 3, when it would be great to change to 3.95, for example. (I didn't made real calcs here, this is just an example).

Do you know a workaround for this?.

Write a decently high resolution page in a picture, and for zooming, scale the single picture.

Addition, if zooming larger than the high resolution picture allows, go back to drawing the way you used to before.

One good way to solve this is to output text on screen one character at a time and counting the Y-coordinate by using Printer.TextWidth of whatever has been printed so far. That eliminates the small differences in font widths between screen and printer fonts.

You can use the TBGRAVectorizedFont from BGRAVectorize.
