Hello Forum,
I have a problem with the following code where the resulting image is suppose to have a red box shown at the given location but sometimes there are multiple boxes drawn at varing sizes. I think it is due to the jpeg compression but i'm not sure how to take the resulting jpeg image and output it in a loss less format.
Could someone help me with these 2 issues?
Thank you!
Function AddInfoBlock(photo, txt1, txt2,txt3: string): boolean;
var TS: integer;

with frmmain.ImageEnVect1 do begin
IO.LoadFromFileJpeg(photo);
LayersAdd(IO.Bitmap.Width ,strtoint(getini('Printer','BoxHeight','60'))
,ie24RGB,0,IO.Bitmap.height);
// White fill the new layer
Proc.Fill(CreateRGB(255, 255, 255));
// Output our text
