I try to create a pdf file with Tlabel and Tmemo.
But after create I lost my polish letters

It should look like this:


but I get:


I try to convert to string/ansistring/widestring or use other font charset.

What else I can to do?

Oh, OK. It is much easier with layers. Please try this method:

// Supports TImage, TShape, TLabel, and TMemo
// OutputTextAsImg: Useful to support non-ANSI character sets and custom fonts

But my Tmemo, Tlabel and Tedit objects are placed on panel.
xequte Posted - Apr 09 2019 : 19:21:44
Yes, that is a good idea.

You can call:

https://www.imageen.com/help/ImageEn/TImageEnView.LayersConvertToImageLayers.html

e.g.

for i := 0 to ImageEnView1.LayersCount - 1 do
  if ImageEnView1.Layers[i].Kind = ielkText then
    ImageEnView1.LayersConvertToImageLayers( i );


Call SaveUndo and then Undo to make the change temporary during the PDF generation.

maybe is it possible to add a memo object as an image?

Hi Pawel

Unfortunately at this time, only the ANSI character set it supported. Improvements in this area are on the to-do list.
