Problems Clipart144144Japanese Calendar 2017
https://openclipart.org/detail/270458/japanese-calendar-2017
Tue, 10 Jan 2017 16:51:19 -0400j4p4nUser JayNick did a great job making a clickable SVG calendar, I liked it a lot but it was locked into one geographic region. So I tried to hack it (with some good help from JayNick) into showing Japanese holidays (in English for this one) so people in other regions could use it too!
Several problems though...
* Japanese holidays have super long English official names so I had to abbreviate them etc.
* Many Japanese holidays slide around on the calendar in order to be on the closest monday to give a three day weekend (that's called the "happy monday system") so those holidays are only legitimate on this calendar for the next for years.
* Mountain Day is a "new" holiday suddenly added to the calendar recently, so it will show up on older dates but didn't actually exist at earlier dates.
* Two Japanese holidays (the equinoxes) are only announced the year before, so no way to do a multi-year calendar that I can see? Although often roughly the same day, but not always exactly.... So sadly had to skip those ones. (Two missing holidays? Gosh!)
Anyway, long story short this is still full of bugs and not perfect. But I thought I would get it out there. Also, for a full explanation on how to use this image, see the source image at the link to the right. cheers!https://openclipart.org/detail/270458/japanese-calendar-2017http://creativecommons.org/licenses/publicdomain/Mental Math

Sun, 11 Dec 2016 19:30:23 -0400j4p4nSo in Japan there is a New Years tradition to put some money in an envelope and give it to kids you know (I know, that sounds weird!) so I thought I would make a template! Made this one basically by hand, so if you don't like the design it is my problem! haha)
Just print, cut, fold and glue (or tape!) and you have an instant money envelope to use for giving money to someone on new years. (If you are wondering about that thing on the card, that is a "Shishi" what Japanese people use for the "Lion Dance" to bring in the new year!)https://openclipart.org/detail/268356/print-out-otoshidamahttp://creativecommons.org/licenses/publicdomain/newsprint filter

If the image filter primitives are set to different sources it can produce the common "dot" haltone pattern.
Also can be used for hatching, cross hatching etc.
Quite a complex filter in the filter editor, although it renders easily and you can zoom in to the max with no problem.
Builds up the lightness values of the original object but discards the actual hue&saturation so it's best used on black&white/duotone sources.https://openclipart.org/detail/267950/newsprint-filterhttp://creativecommons.org/licenses/publicdomain/curly remix

Fri, 28 Oct 2016 21:28:27 -0400Lazur URHNow inkscape 0.92 about screen contest is on. Deadline is November 13, 2016.
Time to revisit this curly mess of a clipart.
Somehow the rendering glitch wasn't present in 0.48 on the metallic part.
Anyway, other notes.
In general, it relies on masking much, which does not transfer right to pdf-s alone.
Then there is the yellow bent shape, which is the result of a diffuse filter -even though at the time I didn't get the real grasp of it.
First, for such a relatively simple shape that is a huge overkill.
Secondly, because the diffuse filter uses alpha values as an input, I drew the shape and masked anotherone with it -could have been much easier by simply adding a colormatrix filter primitive in luminance to alpha mode... and that shape was drawn by markers along a path which alone is overly complicated.
May this clipart serve as a simpler version.
Not sure about the logo part, may not be welcomed here -but noone had a problem with it for two years.
Anyway, will upload a remix without the logo as well. https://openclipart.org/detail/265219/curly-remixhttp://creativecommons.org/licenses/publicdomain/duotone filter test

Thu, 29 Sep 2016 02:32:56 -0400Lazur URHNow, how to deal with this one...
usual problem with repeating patterns in a kaleidoscope/circular arrangement, is if one part exceeds the boundaries but is still visible underneath another repeat.
As a regular approach, adding an opaque backdrop to cover the area could solve -but not this case. Since the original image was made up by such overlaps.
Speaking of overlaps, this results in a messed up visual structure...
so this case, the repeated original pattern was the source for another arrangement with proper clipping.
Bit resource heavy approach if you want to start out that sloppy/want to have a see-through repeating pattern. Because now the original group is cloned 32*32=1024 times.
But that is necessary for a clean design.https://openclipart.org/detail/262936/kaleidoscope-32-square-2http://creativecommons.org/licenses/publicdomain/kaleidoscope 32 square

Sat, 03 Sep 2016 14:17:27 -0400rygleRemix of a remix. Both the original and the first remix have a problem exporting to PDF in Inkscape (hangs app v.0.91/0.92 on Win & Linux) and on OpenClipart.org (makes a 0 byte file) because two objects (the coloured swirls) are converted to a pattern before a clipping path was set. Ungrouped, removed clipping path, converted pattern to objects, re-clipped the two objects/paths separately and re-assembled. Now it should export to PDF in Inkscape and OpenClipart.org.

https://en.wikipedia.org/wiki/File:Nelson_A._Miles_by_Brands_Studios,_1898.jpg
According to https://en.wikipedia.org/wiki/Wounded_Knee_Massacre, General Miles sent this telegram from Rapid City to General John Schofield in Washington, D.C., on December 19, 1890:
?The difficult Indian problem cannot be solved permanently at this end of the line. It requires the fulfillment of Congress of the treaty obligations that the Indians were entreated and coerced into signing. They signed away a valuable portion of their reservation, and it is now occupied by white people, for which they have received nothing.
They understood that ample provision would be made for their support; instead, their supplies have been reduced, and much of the time they have been living on half and two-thirds rations. Their crops, as well as the crops of the white people, for two years have been almost total failures.
The dissatisfaction is wide spread, especially among the Sioux, while the Cheyennes have been on the verge of starvation, and were forced to commit depredations to sustain life. These facts are beyond question, and the evidence is positive and sustained by thousands of witnesses.?
In 1904 he ran for President but only received a handful of votes at the DNC (according to https://en.wikipedia.org/wiki/Nelson_A._Miles).https://openclipart.org/detail/253319/general-nelson-appleton-miles-in-1898http://creativecommons.org/licenses/publicdomain/Karl Friedrich Gauss

Tue, 07 Jun 2016 00:06:04 -0400AdamStanislavLithograph from 1828, by Siegfried Detlev Bendixen, showing a portrait of the German mathematician Carl Friedrich Gauss at the age of 50. Source: http://commons.wikimedia.org/wiki/File:Bendixen_-_Carl_Friedrich_Gauß,_1828.jpg.
From en.wikipedia.org/wiki/Carl_Friedrich_Gauss: ?Johann Carl Friedrich Gauss (/?a?s/; German: Gauß, pronounced [?a?s]; Latin: Carolus Fridericus Gauss) (30 April 1777 ? 23 February 1855) was a German mathematician who contributed significantly to many fields, including number theory, algebra, statistics, analysis, differential geometry, geodesy, geophysics, mechanics, electrostatics, astronomy, matrix theory, and optics.
Sometimes referred to as the Princeps mathematicorum (Latin, "the foremost of mathematicians") and "greatest mathematician since antiquity", Gauss had an exceptional influence in many fields of mathematics and science and is ranked as one of history's most influential mathematicians.?
Yes, he was all that and a lot more. But my favorite story is from his childhood. It is said one day his math teacher needed to do some work instead of teaching, so at the beginning of the lesson he told the pupils to add up the numbers from 1 to 100. They starting working and the teacher started doing whatever it was he needed to do. But just a few minutes later, young Karl raised his hand and said the numbers added up to 5050. The teacher just shook his head and told Karl not to fib.
Closer to an hour later other pupils started raising their hands and they also said the result was 5050. The teacher then asked Karl how he could calculate the result so quickly. Karl said that 1+100=101, 2+99=101,3+98=101,...,50+51=101. There were fifty such pairs that added up to 101 each. Therefore, the sum of the numbers from 1 to 100 equals 50 times 101, and that is 5050. Duh!
Whether the story is true or not, that is the basis of Gauss? algorithm for adding any sequence of numbers starting anywhere and ending anywhere else. And it shows Gauss would make an amazing computer programmer because this type of problem solving is the heart of computer programming.https://openclipart.org/detail/250953/karl-friedrich-gausshttp://creativecommons.org/licenses/publicdomain/Bratislava in 1588

Note the castle only had one tower in this picture, while in later centuries, and up to today, it has four and has often been described as an upside-down table.
According to a legend, during one period of history the inhabitants of the castle often woke up on the floor, aching, with all the furniture messed up in disarray. They had no idea what was happening, so they posted night-time observers outside the castle. And, sure enough, one night a giant came by on his way from one end of Europe to the other. He wanted to rest, so he turned the castle upside-down and sat down on it. When the night observers explained what mess he was causing, the giant apologized, and they have had no problems ever since.
Anyway, what puzzles me about this image is the island in the middle of Danube with deer on it. And another, right by the city. Was the water level of the Danube so low in the 16th Century, or did Braun and Hegenberg just made it up?https://openclipart.org/detail/250785/bratislava-in-1588http://creativecommons.org/licenses/publicdomain/Support: citizen monitoring - common guy with bGeigie radiation detector

Mon, 04 Apr 2016 18:08:50 -0400AdamStanislavCarl Gauss?s formula to quickly add up all numbers from 1 to n. He came up with it as a school child when his math teacher wanted to keep the students busy for an hour, so he asked them to add up all the numbers from 1 to 100. Much to his surprise, young Carl told him in no time the result was 5050.
When asked how he could add up all those numbers so quickly, Carl said that 1+100=101, 2+99=101, etc, 50+51=101, therefore, the sum of all numbers from 1 to 100 was 101 multiplied by 50, which is 5050.
This graphic is the same formula, scribbled by my hand, just generalized to the sum of numbers from 1 to any number n. It is a classical example of how to solve a seemingly hard problem so easily that even a child could do it (even if not every child :).https://openclipart.org/detail/245716/carl-gausss-formula-to-quickly-add-up-all-numbers-from-1-to-nhttp://creativecommons.org/licenses/publicdomain/Contiguous Memory Problems Comic

If you get to the parent objects you can modify the shape still retaining its structure though it can get berzerk alot ways.
Try moving the handles of the parent rectangle on the parent layer, the corner rounding should work with no problem.
