Re: How to make a "perfect grid" in BMP ? [solved]

Believe I figured it out, via a small trip through PPM format. I marked this thread as solved. The solution is to make sure the lines are not Antialiased.

I have the need to programatically create a 1 bit BMP grid, meaning that I have the following parameters: Width of file in pixel Height of file in pixel line width in pixel line offset in pixel I have done it in PerlMagick so far, but could use Imagemagick directly if need be, that's no problem.

PerlMagick Annotate Rotate text

I have (FINALLY) found out how to rotate text in PerlMagick. But the logic does not match what I expected. First : version = ImageMagick 6.9.1-2 Q16 x86 2015-04-14 http://www.imagemagick.org My goal is to write text vertically rotated 90 degrees clockwise. I kind of expected the syntax to be this: $...

Drawing a 2 color (monochrome/bilevel) image takes forever

I have made a Perl script to draw vertical lines at fixed distances. Output must be 2bit BMP (bilevel). The image size is 600 DPI fixed. Drawing and image generation works fine, and is super fast. It's the writing that is a time killer. An image of 15000 pixel horizontal works OK, and is done in 7-1...

Re: Cannot for the life of me get annotate to do anything

This may be necro-posting, but I had exactly the same issue, and found what seemes to cause the situation. This does not change the image: mogrify -pointsize 150 -fill yellow -gravity north -annotate "%t" x.jpg But this works as expected: mogrify -pointsize 150 -fill yellow -gravity north -annotate ...

Re: Add new fonts to pango (ghostscript)

Maybe I am mistaken about Pango vs Ghostscript. But I did not find an option to call a custom font and use that.

Will make some more trials later.

About the version - I do not know where I got it from. Will upgrade soon then. Sorry I can't be of more help.

Offline version of Anthony Thyssen examples ?

The ImageMagick documentation is included with installations. Good !

But does an offline version of the excellent (and much much needed) examples from Anthony Thyssen exist ? Even a zipped website copy would be perfect. I don't always have online access when on the road.

Re: Converting raw greyscale BMP image

According to my arithmetic, 35700 = 300x119 (not 118). convert -size 300x119 -depth 8 gray:qwerty.raw q3.bmp This works for me (IM v6.7.9 on Windows 7). Snibgo - I never thanked you for the solution you gave here. This way works great. convert -size {xsize}x{ysize} -depth 8 gray:{rawfile} outputfil...

Drawing on bilevel PNG is (very) slow

Related to my previous post ( http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=24069 ), I am making experiments with annotation and drawing on the image. In principle all works. But as soon as I work with monochrome (bilevel) images, ImageMagick becomes extremely slow. I have an Intel...

Re: Large 1bit BMP with text, how ?

It seems that IM doesn't generally want to create bilevel BMP files. But it will do, if the input is a bilevel PNG. Thank you :) It's beyond my understanding why this is not working, since it's such a simple format and used everywhere in Windows + industrial machines world. Oh well. I can achieve t...
