Thank you for your reply , now new problems appear , if I fave white text in the text.png the text will not show , and the quality is pour , is there something to do about that ?

Please advise.

Best regards,
Claudiu.

I don't know how you could handle an image which has both black on white text and white on black text other than to do it in pieces.

As to the quality, the smaller text in text.png is not very good and I don't think ImageMagick can really do much to improve it. You might get a slightly better output image if you saved it as PNG.

If the background is white! DO NOT ADD IMAGES.
Image adding is used for blending images, it is not used for merging images with white backgrounds...

You should be using Multiply instead..
See http://imagemagick.org/Usage/compose/#multiply

Also the last example in Image annotation!

I also would NOT just set white to transparency. While it will work parts of the image that fall on top of each other will not merge as you would expect.

That will require you to some how specify what white parts are important, and what are not important. For that you may need to use a masking image of some type.
