Adding text does not work

[Peter2]

I used XnConvert to create the code to adding a text. This was the result:

Code: Select all

nconvert -text_font Arial -text_color 0 0 0 -text_back 0 0 0 -text_flag top-left -text_pos 500 400 -text_rotation 0 -text "sdfefhrfghrfh
fhgfhfg
dghfdgh" 

Then I removed the linefeed and added input and output:

Code: Select all

nconvert -text_font Arial -text_color 0 0 0 -text_back 0 0 0 -text_flag top-left -text_pos 500 400 -text_rotation 0 -text "sdfefhrfghrfh" -o y.tif x.tif

The result was that it created "x_1.tif" and a lot of errors:

Code: Select all

Error: Can't open file (0)
Error: Can't open file (0)
Error: Can't open file (0)
Error: Can't open file (-text_back)
Error: ....

What is wrong?
(Current nconvert 6.21)

First progress:
It seem to depend on the font size. The help says:

Code: Select all

          -text_font name size  : Font name and size

Now I used:

Code: Select all

nconvert -quiet -rotate 90 -text "hallo" -text_font Arial 5 -out tiff -c 7 -o y.tif x.tif

It puts the text in the upper-left corner, but "size 5" or "50" or "500" - the result is the same; only a few pixels high.

Then I continued:

Code: Select all

nconvert -quiet -rotate 90 -text "hallo" -text_font Arial 5 -text_flag bottom-left -out tiff -c 7 -o y.tif x.tif

-> The text stays in the upper-left corner.

Right for XnConvert, size must be added

Else -text must last command

Code: Select all

nconvert -quiet -rotate 90 -text_font Arial 5 -text_flag bottom-left -text "hallo" -out tiff -c 7 -o y.tif x.tif

Right for XnConvert, size must be added

So the export from XnConvert is wrong.

Else -text must last command

Thanks. Please add to the "-help command" in nconvert.
