[JFreeChart] size of points
How can I do to increase the size of points on a FastScatterPlot???
Thanks
Dear sturmca,
1. what is the open source PRC library and who are using it?
2.
a) There is no way to control poit size in U3D (file format limitation).
b) You can set point size in PRC.
3. You can create several point clouds that differ in nothing but point size and control visibility of that clouds via 3D JavaScript.
The down side is that there is no way to reuse point data in PRC, so file size will grow.
May be making a mesh but rendering it as points is a workaround, but I did not try that.

We have a user who has Adobe CS3 installed on her system and when she prints PDF files to our color printer, they come through with the page size in points rather than inches. This causes the job to fail to print we haven't been able to find a way to fix it.
It happens both with PDF files she has created and those created by others. We have reinstalled the print drivers and PPD files once already and that didn't help. I also found that she had distiller 3.0 installed and it's preferences were set to points but changing that didn't solve the problem either. I also tried printing a PDF from Adobe Reader 8 and it printed fine. The problem only happens when printing from Acrobat Professional (which is the default application for opening PDF files.)
Anyone have any ideas what could be causing this problem and how we might fix it?Peter,
I have looked at this again in Pages ’09, and via Page Setup > Paper: Manage Custom Sizes..., it will not let me override the inch measurements.
Try this to get two decimal places. Double-click the mm value in the paper size to select all, and then just type your mm setting with two decimal places (no mm text designation) and then tab out of that entry window. The two decimal setting is retained.
This is redundant knowledge, but here is the conversion fluff. Inches in Page Setup may need to be set to approximate closest points. In the Postscript (cough) world, the conversion is:
1 Point = 0.01388888889 Inch
And the calculator (with round option). -
How do I change font size from points into pixels?
I used to be able to set font size in points but CS 6 has removed this? Please dont say that points = pixels. They do not. See for yourself. A photoshop doc and an Indesign doc have the same pixel size. A 20 point character "A" in InDesign, will be larger than a 20 pixel character "A" in photoshop. This creates hours of extra work when translating text heavy InDesign documents into Photoshop PSDs. Is there any workaround? Help!
Ok, I know why you dont understand my question. I should have said, that points in InDesign do not equal pixels in HTML (and I should have left Photoshop out of it).
My problem is going directly from InDesign to HTML CSS code. I used to be able to look at the type in my layout sketch in InDesign, select pixels in the units preferences and (assuming I am using the same webfont thanks to google fonts and the @fontface style) the font size would match exactly when I view the webpage in a browser. But now, when I try to code my webpage fonts in pixels, using the value from InDesign's points, fonts sizes dont match when viewed in borwser. This may seem like I am splitting hairs to you but it makes a big difference if I can just look at my InDesign sketch and see the excact size of the type without having to export a tracing/guide image and try to match visually. It just worked when I could see font size in pixles in InDesign in CS 5.5 but does not work in CS 6.
Try a test: make a div in webpage with same pixel size as an InDeisgn doc. Use a defualt font like helvetic that is aval. to both InDesign and your browser. A 20 point word will not match a 20 pixel word in the same font.
Also: I believe I rulled out any font replacment issues. For my designes, I am using the same font in both the InDesign doc and webpage code. I am using google fonts (donloaded for indesign and "link href" in head of code on webpage and/or using the @fontface style). -
Hi coders, I have implemented a line chart from the JFreeChart and have got it working nearly how i want. The only problem i have now is that there are 2series using a line and 1 series using points, i was wondering if anyone knew how i could change the colour of the individual series and also the type of point or line they may have.

How to specify custom page size in points?
Have done the usual searches and not hit anything.
Has anyone worked out how to get the custom sizes in Print Setup… to be measured in Points?
I have a job where I need to work to screen resolution.
The two System choices are for Metric which oddly shows in mm when everything else is in cm, or US measurements which are in inches (at least they aren't cubits).
Nothing I see will switch it to the most accurate, by pdf/PostScript standards, of showing the measure in points.
I have a vague recollection of having done this years ago in an OS far, far away. Could have been OS9, Windows or Linux of some ilk.

JFreeChart and 1000 points!!!!!
Hi everybody !!!!
I would like to display on the graph 1000 points. I display with the method :
dataset.setValue(b, composant, ""+j);
I know that there are a method called :
dataset.addSeries(series);
But I don't know how to use it. Have you got any example of source?
Thanks by advance!!!Is someone have an idea, how I can realize that?thanksI'm pretty sure that JFreeChart comes with something called "an API". That's some magic stuff that explains what certain methods do. You should try to read it. And if it's unclear, I'm sure there is a JFreeChart forum somewhere to help you.

Using pixels rather than points to specify the size of a font
The font constructor takes the size in points as its 3rd parameter like so:
new Font("Times New Roman", Font.PLAIN, 12);
Is there any way to use pixels to specify the size instead? The reason I ask is that point specified fonts differ in size from one platform to another (depending on the systems DPI - Windows typically has 96 while the Mac has 72). Obviously if we specify the size in pixels we don't get this problem.
Thanks in advance!
-PeterActually, that's the point of using points, to specify character size in a manner fairly independant of the pixel resolution.
However, what you probably could do is to get a FontRendererContext from the GraphicsContext you propose to use, then get the point-to-pixel transform from that, and use that to transform pixels into points. -
.pdf changes the point size of type
By state law, we have to produce legal documents in 13-point type. When we convert a 13-point WordPerfect document into .pdf, the point size ends up reduced to about 12-point. What do we do? I can't find any way to tell Adobe to make the point size 13 point.
How do you convert?

I'm working on a website for the first time (always been print-only) and I've done the design rough in Illustrator.
I've been working with fonts sized in points, but from my understanding I need to be working in pixels?
When changing the font size from points to pixels in Preferences > Units, my 10pt font shows as 10px fonts. As far as I understand this is not correct? Is it correct and why; and how do I ensure my fonts are the right size for screen?When changing the font size from points to pixels in Preferences > Units, my 10pt font shows as 10px fonts. As far as I understand this is not correct?
When Illustrator uses "pixels" as a unit of measure (which it is not), it is really using points. All of Illustrator's underlying measures are in points (1/72 inch).
I'm not sure what you're struggling with re webpages; but you can code text size in XHTML / CSS as pixels or points or as percentages.

Photoshop will only let me use custom font sizes
Hello
I've been having a strange issue for awhile that I thought would eventually go away with an update but hasn't. Having used photoshop for years, I've always been able to click in the text size menu of the character panel and either type in a pt size or increment larger or smaller with my up and down arrows on the keyboard. I can no longer do that -- when I try to type in the new font size -- say 25 -- my text is actually replaced with the numbers "25" and the font size stays the same. If I choose a default size from the drop down menu (18, 24, 36, 48, etc) it will change size but I'm not able to enter any custom sizes. I get the same behaviour in the option bar.
I'm using the most up to date version of CC on an late 2012 Imac 2.9 GHz Intel Core i5 running the most recent version of Mavericks ( OS X 10.9.2 (13C64)), but this has been happening since Mountain Lion and atleast the first version of CC, possibly CS6.
It doesn't matter what font I use and happens on every document. I've also tried to reset the tools and delete the preferences.
I do use the no-longer -supported free version of Linotype Explorer but it seems more like a photoshop issue.
This is obviously really frustrating and I haven't been able to find anyone else with the exact problem. If anyone has any ideas I'd really appreciate it.
Thanks!The key combos still work for changing type point size, just not in Preferences-controlled-increments (instead, whole point sizes, 1 point at a time) -- and you can also input any point size. Are you using the Character Palette?
On Mac, "Command-Shift->" increases the point size 1 point, and "Command-Shift-<" reduces it by 1 point size (if the type is selected).
If you use the Character Palette (Command-T on Mac), you can input any point size you want, up to 1/1000th of a point: 24.582 pt. size, for example. -
How can I change the size of a logo?
I started making a logo in Illustrator. At the beginning I had to give the size in points. Now I'm finished and I want to change it. How can I do this?
Pieter,
Always keep the original artwork, so make changes to a copy. In this case you should keep them in separate documents.
If you wish to have the size(s) changed so that everything has the same dimensions in the other unit, you may use the conversion factors, 1 inch = 72 points, 1 mm = 1/25.4 inch, etc.
So if you wish to have the same dimensions in mm as you had in points, to do it with full(est possible) accuracy you need to select everything, then with Scale Strokes and Effects ticked in the Transform palette flyout:
1) Add *72 in the W field and press Ctrl/CmdEnter (to have the same dimensions in inches);
2) Add /25.4 in the W field and press Ctrl/CmdEnter (to have the same dimensions in mm).
Remember to untick Scale Strokes and Effects if unneeded afterwards.
You can check the dimensions of the original and converted artwork against each other when you have them in the corresponding File>Document Setup>Units. -
How to get the size of the cuurrent illustration
Sorry, I made a mistake before this one. The questios is this: can anybody tell me how can I get the size of the current illustration, (as oposed to the page size) in points. Something like 120 points wide and 87 points High?. What function do I need to call?
From AI Function reference (included with CS2 SDK):
AIDocumentSetup setup;
error = sDocument->GetDocumentSetup(&setup);
if (error) goto processError;
writeDocumentSetup( &setup );
The AIDocumentSetup record returns the following information:
typedef struct {
AIReal width, height;
AIBoolean showPlacedImages;
short pageView;
AIReal outputResolution;
AIBoolean splitLongPaths;
AIBoolean useDefaultScreen;
AIBoolean compatibleGradients;
AIBoolean printTiles;
AIBoolean tileFullPages;

Array size limitations... and prime number programs.
What are they? I am an ameteur programmer who wrote an extremely efficient prime finding program, if i do say so myself. The program doesnt find high primes, just prime numbers from 1-1,000,000,000 so far. Thats one version, the next version i use is faster, but because it uses an ArrayList, it can only do the primes 1-10,000,000. I am trying to work the programs up to primes with 50 or more digits, but ArrayList runs out of space, Integer is too small, I dont quite know how to switch all my code to be compatable with BigIntegers, and I cannot find a limit to arrays. I guess that I could find big primes if a) Integer was bigger, b)I tried, but what i wanted to do, because the second program is way more effecient, is to use an array to store primes instead of an ArrayList. The only problem? Arrays cannot be appended, so I need to know the limit in size for an array... So far, from my tests, I have found the limit to be somewhere around, 15,380,277. The only problem with this is that every time i compile, i can use a different number. So I would like it if a) somone could tell me the limit to an array's size, b) ideas for programs that can find primes with 50 or more digits, c) Down below is the code, could someone tell me how to convert it to BigIntegers?
private void primeFinder1root(int beg, int end){
int tmp = 0;
int counter = 0;
int counter2 = 2;
boolean flag;
for(int n = 3; n < end; n+=2){
if(n%5!=0){
flag = true;
for(int d = 3; d <= Math.sqrt(n) && flag; d+=2){
counter++;
if(n%d == 0)
flag = false;
if(flag){
System.out.println(n);
counter2++;
tmp = n;
if(counter2%100000 == 0)
System.out.println(n);
System.out.println();
System.out.println("The program looped " + counter + " times. There were " + counter2 + " primes found. "
+ tmp + " was the last prime found.");
}That is the first progam that does not use an ArrayList, but is still extremely effecient, it only looped 1,744,118,556 times to find the primes 1-100,000,000 which seems like a lot, but it truely isn't. I realize that by using counters and printing, I am slowing the program down immensly, but i am fine with that.
public void primeFinder(){
boolean flag;
int tmp = 0;
int tmp2 = 0;
int counter = 0;
primes.add(2);
for(int n = 3; n < end; n+=2){
if(n%5!=0){
flag = true;
for(int i = 0; i < primes.size()/2 && ((Integer)primes.get(i)).intValue() <= Math.sqrt(n) && flag; i++){
tmp = ((Integer)primes.get(i)).intValue();
if(n%tmp == 0)
flag = false;
counter ++;
if(flag && n!=1){
System.out.println(n);
primes.add(n);
tmp2 = n;
if(primes.size() % 100000 == 0)
System.out.println(n);
primes.add(0, 1);
System.out.println(counter + " " + primes.size() + " " + tmp2);
}This is the code that stores all the primes it finds in an ArrayList, and then compares all numbers to the ArrayList of primes. This is extremely more effecient than the first, looping only 278,097, 308 times to find the primes 1-10,000,000 (the other looped 868,772,491 times). I used 10,000,000 as my example because this program cannot go to 100,000,000 because there are 5,761,455 primes and the ArrayList can only hold ~4,000,000 objects. Because of this ~4,000,000 object limitation on the ArrayList I have set my sites on the Array. This is the reason why I want to know the limitations of an Array if you could please tell me. If you could also, I would like help making my code compatable with BigIntegers as well.
Well, sorry for the very long post, but thank you if you answer it and took the time to read it.
Dumber_ChildI too was in the quest to develop the most efficient prime number code few years ago when I was a student.
Here is a more fine tuned version for your code
public static long findPrimes(int max, ArrayList out){
long count=0;
FastList primes = new FastList((int)Math.sqrt(max));
primes.add(2);
for (int i=3; i<=max; i+=2)
int al_size = primes.size();
double sqrt = Math.sqrt(i);
boolean prime_flag =true;
boolean loop_flag = prime_flag;
for (int j=0; j<al_size && loop_flag; j++)
int val = primes.get(j);
if (i%val == 0)
loop_flag = prime_flag = false;
else if (val > sqrt)
loop_flag = false;
count++;
if (prime_flag)
primes.add(i);
primes.addToArrayList(out);
return count;
Following a data structure to store the prime numbers while processing
Since this holds first number of primes in an array instead of in an ArrayList
the get will work much faster and for those elements the casting is not required
static class FastList
ArrayList list = new ArrayList();
int cache[];
int pointer = 0;
int fastAreaSize;
public FastList(int fastAreaSize){
cache = new int[fastAreaSize];
this.fastAreaSize = fastAreaSize;
public void add(int i){
if (pointer < fastAreaSize)
cache[pointer] = i;
list.add(new Integer(i));
pointer++;
public int size(){
return pointer;
public int get(int i){
if (i<fastAreaSize)
return cache;
else
return((Integer)list.get(i)).intValue();
public void addToArrayList(ArrayList al){
for (int i=0; i<pointer; i++)
if (i<fastAreaSize)
al.add(new Integer(cache[i]));
else
al.add(list.get(i));
When running in my pc
above code detected primes within range 0-10000000 in 281809517 iterations within 6.718secs
while your original code did the same in 278097308 iterations within 13.687 secs.
By the way i removed the check for '5' thats why my code does more iterations.
Notice that I have relocated code like Math.sqrt and ((Integer).....).intValue() to reduce the re calculating the same thing. That saved a lot of time. -
Get system font size (CL_GUI_RESOURCES= GET_FONTSIZE)
I'm using CL_GUI_RESOURCES=>GET_FONTSIZE to retrieve the SAP GUI font, so that I can adjust some web content dynamically.
However, I'm getting some strange results back, and wanted to know how I should interpret the result of this method.
When using SAPGUI for Windows 7.30, with a system defined font size of 9, this method returns:
90,000
At first I thought maybe I just need to arbitrarily divide by 10,000 to get the font size in points.
However when using SAPGUI for Java on my retina macbook pro, with a system defined font size of 12, this method returns:
78,545
Can anyone tell me exactly what this method is returning, and how I can convert it to the actual system font size in points?Yes you can't use CL_GUI_FRONTEND_SERVICES from a BSP page. CL_GUI_FRONTEND_SERVICES using activeX controls running within the SAPGui to perform most of its actions. Since you have not connection to a SAPGui during a BSP page, you can use this class.
You might want to look at scripting against the Microsoft FileSystem Object. There is a size property of both the folder and file object. A search of Microsoft's website will show lots of documentation on this object and code samples in VBScript and JavaScript. This does opens up all kinds of security concerns from the browser however. -
