I trying to add a caption to existing image, but it produce two images, one with actuall caption and another just copy of source image...
Doing it by trying these examples http://www.imagemagick.org/Usage/text/#caption
like
convert Book.png -background lightblue -fill blue \
-size 320x caption:'This is a very long caption line.' \
caption.png
result is two images caption-0.png and caption-1.png
What am I doing wrong here?
Try this:
convert Book.png ( -size 320x -background lightblue -fill blue caption:"This is a very long caption line." ) -gravity center -composite caption.png
I am not sure you can leave out the height of the caption as the font size is calculated to fit the caption bounding box.

I am using ImageMagick to add text to an image. I used to -gravity Center flag to put the text in the center of the image. But I think this is resulting in the text being center aligned too. I want the text at the center of the image but left aligned. Here is an example of what I'm trying to have:
This is the output I'm getting:
Current output
This is what I want:
This is my requirement
How do I accomplish this? This is my first time using ImageMagick. Please guide me.
Here is one way to do that in Imagemagick 6. I specify the background color, the font color (fill), the font and the pint-size and gravity west (left side). I use label: to create the two lines of text with a new line between them. This creates a text image of the size needed to hold the text. Then I pad the image all around that to the final size with the text image in its center using the same background color.
convert -background black -fill white -font ubuntu -pointsize 28 -gravity west label:"This is line 1 of text\nThis is line 2 of text" -gravity center -extent 400x300 result.png
See
https://imagemagick.org/Usage/text/
https://imagemagick.org/Usage/crop/#extent
ADDITION
If you want to put the text over an existing image, then you do something similar, but in place of the extent, we composite the text image over the background image.
The following is Unix syntax. For Window, remove the backslashes \ before the parentheses.
Input:
convert lena.png \( -background black -fill white -font ubuntu -pointsize 21 -gravity west label:"This is line 1 of text\nThis is line 2 of text" \) -gravity center -compose over -composite result.png
Result:
Or if you do not want the black background, use "none" for the color.
convert lena.png \( -background none -fill white -font ubuntu -pointsize 21 -gravity west label:"This is line 1 of text\nThis is line 2 of text" \) -gravity center -compose over -composite result2.png
convert inputImage.jpeg -gravity South -size x32 label:"Morning in paradise" -geometry +0+40 -composite starImage.png -composite finalImage.png
With this command, I can add text at the bottom of inputImage and another image on this text. But how can I set (or prefix) the starImage image to the left of the text that has a dynamic width and fixed height. I have attached some images below to explain what I want to do.
Obtained result
Expected result
You can read the star image, create the text label, and append them together inside parentheses. Then composite that assembled star-text image over the main input image. A command like this should get pretty near what you described.
convert inputImage.jpeg -gravity center -size x32 \
\( starImage.png label:"Morning in paradise" +append \) \
-geometry +0+40 -gravity South -composite finalImage.png
If you want a star on both sides of the line of text, you can read the "starImage.png" in once more after creating the label and before appending.
I think what you should do using Imagemagick is to set the width you want for the text so that there is room for the star image to be append on each side and have some padding as well. Here is how I would do it. Since you did not provide your input or star image, I have simulated the image as a blue image and taken some graphic image that I had around to simulate your star or logo. I first measure the desired width. The width is 70% of the difference is width between the large blue image and twice the width of the logo. I append the logo on each side of the text image, then composite that near the bottom of the blue image to create your final image. If this were in Imagemagick 7, it could be done in one command. This is Unix syntax.
Image:
Logo:
width=`convert background.jpg logo.png -format "%[fx:0.70*(u.w-2*v.w)]\n" info: | head -n1`
convert background.jpg \
\( logo.png \
-size ${width}x -background none -fill black -font Arial -gravity center label:"THIS IS A TEST" \
logo.png \
+append \) \
-gravity south -geometry +0+50 \
-compose over -composite \

I am using Image Magick to overlay a dimmed caption to an image, with IM automatically choosing the best fontsize:
convert -background '#0008' -fill white -geometry +0+330 -size 370x60 caption:$title $image +swap -composite $imageOutput
My problem is that there is not enough space around the text, I would like to add some "padding". I usually do that with the -border option but if I add this to my command above, the caption is not dimmed anymore.
Do you have a solution to create a dimmed caption with enough room around the text?
I have a solution, but it's a bit of a kludge because I had trouble extending or bordering a semi-transparent background. In the end, I just constructed the caption on a black background and bordered it in black, then I tweaked the alpha channel afterwards:
convert -background black -bordercolor black -fill white \
-size 370x60 caption:"This is the title" \
-trim -border 20 -channel A -fx '(lightness/2)+.5' \
-geometry +0+200 background.gif +swap -composite result.png
The only tricky part is -channel A -fx .... The first part means that we are only affecting/modifying the alpha/opacity channel. The 0.5 means that all pixels become at least 50% opaque, and (lightness/2) means that absolutely white pixels, i.e. your lettering, (which will have a lightness of 1) become fully opaque because 0.5+(1/2) totals to one. The point of this is to preserve the anti-aliasing around the edges of the letters to some degree.
I'm trying to generate an image using Imagemagick to match a preview in the browser, but the text comes out blurry. Does anybody have any suggestions? Attached is an image with the Imagemagick one on top, and browser one on bottom, along with the IM code.
convert -density 288 -resize 25% -background white -fill black -strokewidth 0 -stroke white -font Rubik-Regular.ttf -pointsize 10 -gravity center label:'This is a TEST!' label_arial.gif
You might find it easier to start with caption which automatically sizes the text the best way to fill a given area. So, as your lettering is around 140x36 pixels, you would do:
convert -size 140x36 -gravity center caption:'This is a TEST!' label.gif
I'm trying to convert a bunch of photos using imagemagick. However, I hadn't figured out how to overlay an image with gradient and write some text on it. I know the text part though:
convert IMG_8408.jpg \
-font URWChanceryMediumI \
-pointsize 250 \
-draw "gravity south
fill black text 0,40 'Some text stuff here'" \
test.jpg
Is there a way to add a white gradient to the bottom? Note, that the image size may vary.

What I want:
I picked the colors so that it's clearly visible what I want to achieve
You can achieve desired output with 3 commands:
a. create the upper part of your image (a solid rectangle with your selected background color):
convert -size 640x200 xc:#A02B2B background.jpg
b. create another image containing the text over a gradient:
convert -size 640x110 gradient:#A02B2B-#126B27 -pointsize 25 -draw "gravity south fill black text 0,40 'Some text stuff here'" text.jpg
c. combine the images to obtain the final output:
montage background.jpg text.jpg -tile 1x2 -geometry +0+0 output.jpg
Note: I modified text creation parameters in step 2 to keep the command short, but you can add back your original settings
Use the following command:
magick -size 640x310 -define gradient:vector="0,107 0,0" gradient:"#a02b2b-#126b27" -flip -gravity south -font script-mt-bold -pointsize 48 -annotate +0+24 "Some text stuff here" output.png
