sorry for late reply. could not get internet access. Now, I have tried it and found following. I clicked and chose edit>cut.Then mouse position appears in top left corner. But, the issue is it does not show absolute pixel position of the image. Suppose , i zoom in 16 times in an image then i should ...

i opened an image using GUI of imagemagick in ubuntu 16.04.3(64bit) . Now I zoomed into the image . I want to know the pixel position of my mouse . Actually my aim is to manually locate pixel position of a particular chessboard square corner in image . In paintbrush in windows , it is simply hoverin...

It has been a long long time . But , better late than never . Here are the results . creating blue concentric circles of varying intensity cd "C:\Program Files\ImageMagick-6.9.2-Q16" c: imconvert -size 510x488 xc:none -fill "rgb(0,0,16)" -draw "circle 250,170 250,180" d...

Hi , I tried in windows identify -verbose "d:\lxuser\for all\personal\more\20140327_185957.jpg" Format: JPEG (Joint Photographic Experts Group JFIF format) Class: DirectClass Geometry: 3264x2448+0+0 Resolution: 72x72 Print size: 45.3333x34 Units: PixelsPerInch Type: TrueColor Endianess: Un...

That helped.
Thank You.
sorry for my late reply.

i have to upload photograph on website which asks for picture size 3.5cmx4.5cm & file size in range 25kb-110kb firstly how can i find out length of my imagefile ? Currently I am using paintbrush in windows using which I resized picture to given centimetres but file size was just 10kb . i already...

taking cue from 'Draw Dim Box' in http://www.imagemagick.org/Usage/annotating/ I just replaced -fill none with -fill '#0008' which makes my circle more noticeable on chess board . I tried convert.exe my-icon.jpg ( +clone -blur 0x20 -shade 110x21.7 -contrast-stretch 0% +sigmoidal-contrast 6x50% -fill...

convert photo.jpg -define jpeg:extent=40kb myimage.jpg
did not work .
Myabe the default profile takes lot of space as pointed out by others,

convert photo.jpg -strip small,jpg
WORKED WELL , Image got reduced to 2kb without change in dimension

Do not resurrect old topics for a new problem, post split to new topic -- Ant I drew a chessboard using convert -size 8x8 pattern:gray50 -scale 10100% chessboard.png Then I drew a circle over it convert.exe chessboard.jpg -fill none -stroke red -draw "circle 353,253 504,201" my-icon.jpg N...

I have photo.jpg of size 44KB its details are Image: d:\sumeet\photo.jpg Format: JPEG (Joint Photographic Experts Group JFIF format) Class: DirectClass Geometry: 107x93+0+0 Resolution: 72x72 Print size: 1.48611x1.29167 Units: PixelsPerInch Type: TrueColor Endianess: Undefined Colorspace: sRGB Depth:...

Seems the one I mentioned above will require scrutiny to decide colour of every pixel of text . That would be complicated. If I have a monospaced font and I know fontsize then can I calculate the area (in pixels) that text will occupy ? Then I wish to calculate average colour of that area . Then put...

Is it possible to write a word over image in such a way that colour of letter is complementary to background.
The colour of every pixel (that will be superimposed by text) should be complementary to average of 8 pixels surrounding it in original image.

Using checkerboard pattern yielded good result . Also I noticed that if I save images in bmp format (bulky) then colour filling using mspaint is nice except the edge of board has an inner grey edge . See attached image.(There ain't any image uploading in posting . I have to point to temporary locati...
