mtpaint 3.49.12- April 2016

[wjaguar]

Do you support all the SVG colors?

Most likely, yes and then some - it is gdk_color_parse() doing the conversion, which in GTK+1 calls XParseColor() and in GTK+2, pango_color_parse(). Either function knows 750+ color names:
/usr/share/X11/rgb.txt
pango-X.Y.Z/pango/pango_color_table.h

New version 3.44.89 available on first post

From 3.44.80, in fact. Thanks, you've uncovered a really nasty memory-corruption bug: I forgot to allocate in-tape memory for one kind of V-code widgets. Patch is attached (should be applicable to any version from 3.44.80 onwards).

Quick as always, thank you wjaguar.

New debian versions (Lucid,Precise and Tahr) 3.44.89

________________________________________________

When I tested these with my Wacom bamboo tablet I found an odd behaviour.
It occurs in Ubuntu and Puppy linux.

Steps to reproduce:

1) Install recent version of mtpaint.
2) Check that wacom driver is installed
3) Set up the wacom driver and make sure that pressure is working in test area.
4) Use a brush (16 pt ) in image. I see that pressure is definitely working.
5) Set down my wacom pen and start painting with my mouse or try to paint a line
with line tool using my mouse.

Painting with mouse is now impossible until the user unticks size,flow boxes
preferences > tablet

Thanks for noticing this. When rewriting mouse handling in 3.44.78, I forgot to set default value of 1.0 before reading pressure (which fails when device is a mouse and not stylus/etc). Patch is attached.

[don570]

I posted a new version of 3.44.89 with the patch.
I checked that it worked in Precise puppy.

I also put in a newly designed .desktop file so that many languages will
have a proper description in the start menu.

Also there is now an Italian right click menu if desired.

-Added Czech language to the list of right click menu items

New version 3.44.90 of mtpaint available in first post
___________________________________________

Rewrote much of scripting engine and supporting V-code parts
Implemented scripting for layers window, settings toolbar, and tools toolbar (under Edit menu)
Name + ":" accesses widget's right-click dialog: "-e/tool flood: =10"
Freestanding ":" closes nested dialog: "-e/layer new w=100 h=100 : name=Layer1"
Fixed crash on errors in script
Fixed highlighting in layer list (damaged since 3.44.53, worse since 3.44.86)
Fixed preview of opacity gradients (since 3.44.72)
Fixed focus when starting with open dock
Fixed selection from script ("-s/all") not allowing width/height=1
Fixed pressure value for mouse with tablet enabled

Is there a problem with large (megapixel) files?
Try to open this http://img.photographyblog.com/reviews/ ... 020_53.jpg with mtpaint. Mine does not open.

mt paint 3.4.88

[dejan555]

Try to allocate more memory in settings
Glad to see there's a new version and that scripting is improved, will compile asap

It's working. The file was corrupt.

[SOLVED] read EDITED at bottom of post
Hi,
this command line feature looks awesome !
again thanks for the new feature !

Just wanting to find references for commandline scripting with mtpaint:
till now i'm doing scripts following the «cut and try» codes ... and get lots of

does not match any item

does not match any widget

error messages

example: i use to convert png image to black and white doing;
- Menu/Palette/Set Palette Size/2/Apply
- Menu/Image/Convert To Indexed/Palette/PNN Quantize/Dither/None/OK
then taking scripts examples from this forum (thanks to all "pionneers" don570, and others ... without forgetting wjaguar ... ), I began to write down this script:

Code: Select all

#!/bin/sh
 for ZAD in /root/my_images/*.png ;do
  SUFFIX=_mod
  mtpaint --cmd -file/open="$ZAD" -palette/set=2 -image/'convert to indexed'/'PNN Quantize' -file/as="$ZAD"$SUFFIX
done 

then got the following message:

Code: Select all

Loading PNG image - Please Wait ...
********************
'-image/convert to indexed/PNN Quantize' does not match any item
[ OK ]

I cannot pass the 'convert to indexed' step ...
Browsing the web i did not find the A.9 section of the handbook (reported in NEWS in github).
Where then to find the right code syntaxes ?

Thanks for any answer/help

Charlie

EDITED: YESSS ! got it !
this way:

Code: Select all

#!/bin/sh
#this script convert all .PNG file(s) located in /root/my_images/ into black and white 2 colours PNN quantize _mod.png files
 for ZAD in /root/my_images/*.png ;do
  SUFFIX=_mod
  mtpaint --cmd -file/open="$ZAD" -palette/set=2 -image/'Convert To Indexed ...' 'index'=2 'palette'=pnn -file/as="$ZAD"$SUFFIX
done  

Found after reading and applying wjaguar' s "how to" here (near the bottom of page !):

http://murga-linux.com/puppy/viewtopic. ... 51249458a7

Tons of thanks

[don570]

Code: Select all

-image/'Convert To Indexed ...'

Yes. Writing out the full menu item is the best way.

Using the first word is a shortcut that sometimes works.
Looking at my examples and Jaguar's will suffice to train people.

The current version of mtpaint v90 has a default command that
is good for making an icon (according to Dmitri)

Hi don570 maybe do you like this post:

http://www.murga-linux.com/puppy/viewtopic.php?t=97752

See you.

[technosaurus]

Does anyone know of a standard way that a program can edit or just view a specific Mime-type. I looked all through http://standards.freedesktop.org but nothing seemed to handle this distinction.

AFAICT there is no way to specify one over another in a .desktop file.
mtpaint is one of those programs that can open X different types and write Y different types.

The reason I ask is that I would like to integrate this info into the package manager and even Rox-Filer's Mime handling such that if you try to open any recognized mime type it will select the user's default OR give the user a selection of apps that support it (with not-installed ones grayed out and will auto-install if clicked). Also if the user right clicks for edit there would be a similar menu except I would also add an asterisk to apps that supported reading but not writing a MIME (as with some of the image formats supported by mtpaint)

[don570]

I've posted the mypaint backgrounds on the first post so users can use them.

Instructions:

Load a background in a mtpaint layer, then do a 'Resize'
Select 'Tile' and enter the dimensions of image desired.


Here I have taken a background and resize with the 'Tile' feature then a 45 degree rotate.

Anyone know where the development version of the handbook is?
Lots of new and awesome stuff since the last release.

I'd like to add the PMM format to my MIME-Type detection library.
even though its not at IANA yet because it does seem to be useful.
I assume the extension is .pmm???
I'm using magic@offset based detection as well so if there is a solid spec, I would prefer to use that rather than reverse engineering it from code or images (my automagic finder code is hit/miss).

[wjaguar]

Anyone know where the development version of the handbook is?

Partly still in my to-do list. Other parts, on my flash drive.
Should have put it on Github too, I know - but the source format is somewhat idiosyncratic (txt2tags), and I have not yet investigated how best to stuff image files into git.

I'd like to add the PMM format to my MIME-Type detection library.

Then do the same thing mtPaint does in do_detect_format(): compare first 12 bytes to "P7\n#MTPAINT#".

I assume the extension is .pmm???

By default, yes. But not necessarily.

if there is a solid spec, I would prefer to use that rather than reverse engineering it from code or images

That part has actually been written, yes. And I'll finally put it on Github before long.
But PMM itself is nothing esoteric - it extends NetPBM's PAM in a compatible way, so that all NetPBM tools work with PMM files as with regular PAM.
