I need to load a imagen in the background. I tried a lot of format (jpg, png, bmp) but nothing works.

The only thing I've got is this:

Sig.SignatureType := stDocument;
Sig.Invisible := false;
sig.WidgetProps.BackgroundStyle:= pbsCustom;
sig.WidgetProps.Background.Height:= 32;
sig.WidgetProps.Background.Width:= 32;
Sig.WidgetProps.Background.ColorSpaceType:= pcstRGB;
sig.WidgetProps.Background.ImageType:= pitCustom;
MS := TMemoryStream.Create;
MS.Seek(0, soFromBeginning);
SetLength(aBArray, MS.size);
MS.ReadBuffer(aBArray[0], Length(aBArray));
Sig.WidgetProps.Background.Data:= aBArray;
sig.WidgetProps.HideDefaultText:= True;

But the image is distorted (show attachment).

Thank you for contacting us.

But the image is distorted (show attachment).

For image type pitCustom and color space type pcstRGB the TElPDFImage.Data property should contain RGB image (3 byte per pixel), without any additional information like BMP file header.

tried a lot of format (jpg, png, bmp) but nothing works.

The jpeg and jpeg2000 formats (only JP2 bitmap format) are supported by pdf standard, in this case image type should be pitJPEG or pitJPEG2000 accordingly.
Please, see: https://www.eldos.com/documentation/sb...etype.html

Note, Background.Height and Width properties should match image dimensions.
