draw ROUND images on a background, is it possible?

[silversonicaxel]

Hi guys,
I need to put some images on a background, and that's working fine with the following code:

Code: Select all

convert -size 600x357 xc:none -draw "image Over 0,0 0,0 'background01.jpg'" -draw "image Over 25,190 0,0 'aktiviteiten01.jpg'" -draw "image Over 200,190 0,0 'cultuur13.jpg'" -draw "image Over 380,190 0,0 'natuur01.jpg'" -draw "image Over 0,0 0,0 'frame.png'" -extent 600x357 -append +repage 638044758.30105944.jpg

I've even some images that need to be put over my background, just circular shaped. Following the rules of -draw command here (http://www.imagemagick.org/script/comma ... s.php#draw) it appears my code needs to change like the following:

Code: Select all

convert -size 600x357 xc:none -draw "image Over 0,0 0,0 'background01.jpg'" -draw "image Over 25,190 0,0 'aktiviteiten01.jpg'" -draw "circle 200,190 0,0 'cultuur13.jpg'" -draw "image Over 380,190 0,0 'natuur01.jpg'" -draw "image Over 0,0 0,0 'frame.png'" -extent 600x357 -append +repage 638044758.30105944.jpg

but I receive this error:

Code: Select all

convert.exe: Non-conforming drawing primitive definition `cultuur13.jpg' @ error/draw.c/DrawImage/3178.

does anybody knows why? thanks in advance

"draw circle" doesn't take a filename as an argument. "draw image" is the only one that does. See http://www.imagemagick.org/script/comma ... s.php#draw

"draw circle" will use a fill colour or tile from an image, so that is one way of doing it. Eg:

Code: Select all

convert logo: -write l0.png +level 30,70%% l1.png

convert l0.png -tile l1.png -draw "circle 100,100 100,200" l3.png

Question, this is circle options:

Code: Select all

circle x0,y0 x1,y1

but if i write

Code: Select all

"circle 0,0 300,150"

or

Code: Select all

"circle 0,0 150,300"

nothing changes.
its behavior is not so clear.

what do x0,y0 x1,y1 stand for then?

what do x0,y0 x1,y1 stand for then?

x0,y0 = centre of the circle

x1,y1 = a point on the cricumference of the circle

You may be better off compositing with a circular mask using -compose ... -composite. Use -draw to create a white circle on a black or transparent background and use that as mask image to cut out a circle of one image and overlay it on another.

see
http://www.imagemagick.org/Usage/layers/#convert
http://www.imagemagick.org/Usage/compose/#compose
http://www.imagemagick.org/Usage/thumbnails/#rounded


Here is an example




#line1 - read the background and foreground images
#line2 - clone the foreground image and make it all black, then draw a white circle centered and to the edges
#line3 - copy the foreground image and the circle image and put the circle into the alpha channel of the foreground image
#line4 - delete the original foreground image and circle mask and composite the modified foreground over the center of the background

convert tile_water2.jpg zelda3.jpg \
\( -clone 1 -fill black -colorize 100 -fill white -draw "circle 64,64 64,0" \) \
\( -clone 1 -clone 2 -alpha off -compose copy_opacity -composite \) \
-delete 1,2 -gravity center -compose over -composite zelda3_circle.jpg

Hi, everything is clear now, and it works perfectly.
Only one thing, what if I would like to position somewhere the circle?
maybe not centered but on a side, how can I set the X and Y of the circle?

thanks a lot

change

Code: Select all

-delete 1,2 -gravity center -compose over -composite zelda3_circle.jpg

to

Code: Select all

-delete 1,2 -gravity center -geometry +X+Y -compose over -composite zelda3_circle.jpg

for which X,Y are relative to the center of the background image.

Or if you want it at the sides, you can change the -gravity to its other compass directions, such as east, west, north, south, northeast, northwest, etc
