  • Convert large raster graphics image(bitmap, PNG, JPEG, etc) to non-vector postscript in C#

    - by Dennis Cheung
    How to convert an large image and embed it into postscript? I used to convert the bitmap into HEX codes and render with colorimage. It works for small icons but I hit a /limitcheck error in ghostscript when I try to embed little larger images. It seem there is a memory limit for bitmap in ghostscript. I am looking a solution which can run without 3rd party/pre-processing other then ghostscript itself.

  • random, Graphics point ,searching- algorithm, via dual for loop set

    - by LoneXcoder
    hello and thanks for joining me in my journey to the custom made algorithm for "guess where the pixel is" this for Loop set (over Point.X, Point.Y), is formed in consecutive/linear form: //Original\initial Location Point initPoint = new Point(150, 100); // No' of pixels to search left off X , and above Y int preXsrchDepth, preYsrchDepth; // No' of pixels to search to the right of X, And Above Y int postXsrchDepth, postYsrchDepth; preXsrchDepth = 10; // will start search at 10 pixels to the left from original X preYsrchDepth = 10; // will start search at 10 pixels above the original Y postXsrchDepth = 10; // will stop search at 10 pixels to the right from X postYsrchDepth = 10; // will stop search at 10 pixels below Y int StopXsearch = initPoint.X + postXsrchDepth; //stops X Loop itarations at initial pointX + depth requested to serch right of it int StopYsearch = initPoint.Y + postYsrchDepth; //stops Y Loop itarations at initial pointY + depth requested below original location int CountDownX, CountDownY; // Optional not requierd for loop but will reports the count down how many iterations left (unless break; triggerd ..uppon success) Point SearchFromPoint = Point.Empty; //the point will be used for (int StartX = initPoint.X - preXsrchDepth; StartX < StopXsearch; StartX++) { SearchFromPoint.X = StartX; for (int StartY = initPoint.Y - preYsrchDepth; StartY < StpY; StartY++) { CountDownX = (initPoint.X - StartX); CountDownY=(initPoint.Y - StartY); SearchFromPoint.Y = StartY; if (SearchSuccess) { same = true; AAdToAppLog("Search Report For: " + imgName + "Search Completed Successfully On Try " + CountDownX + ":" + CountDownY); break; } } } <-10 ---- -5--- -1 X +1--- +5---- +10 what i would like to do is try a way of instead is have a little more clever approach <+8---+5-- -8 -5 -- +2 +10 X -2 - -10 -8-- -6 ---1- -3 | +8 | -10 Y +1 -6 | | +9 .... I do know there's a wheel already invented in this field (even a full-trailer truck amount of wheels (: ) but as a new programmer, I really wanted to start of with a simple way and also related to my field of interest in my project. can anybody show an idea of his, he learnt along the way to Professionalism in algorithm /programming having tests to do on few approaches (kind'a random cleverness...) will absolutely make the day and perhaps help some others viewing this page in the future to come it will be much easier for me to understand if you could use as much as possible similar naming to variables i used or implenet your code example ...it will be Greatly appreciated if used with my code sample, unless my metod is a realy flavorless. p.s i think that(atleast as human being) the tricky part is when throwing inconsecutive numbers you loose track of what you didn't yet use, how do u take care of this too . thanks allot in advance looking forward to your participation !

  • Painting to Form then to Printer

    - by jp2code
    I often find myself needing to create custom reports that do NOT work with Crystal Reports or Report Viewer. Often, I hack a DataTable together and dumping that into a DataGridView control. It is never pretty, and printing is difficult. What I need is a class that I can call using the OnPaint event, but I've never sat down and written all of the Pen and Brush commands until now. Painting to the screen and painting to a printer both use the Graphics object, so I want to build a class that I'd pass in the Graphics object, my window bounds (a Rectangle), and some data (in the form of an instance of my class) that I'd use to paint a form or a sheet of paper. That sounds like a great concept! Surely, someone has done something like this before. Does anyone know of a book, a website tutorial, or video that goes into this? If someone wants to write all that out for me here, more power to you - but I'd think that would be too much work.

  • Screen capture of MDI app with OpenGL graphics using MFC

    - by NPVN
    In our MDI application - which is written in MFC - we have a function to save a screenshot of the MDI client area to file. We are currently doing a BitBlt from the screen into a bitmap, which is then saved. The problem is that some of the MDI child windows have their content rendered by OpenGL, and in the destination bitmap these areas show up as blank or garbled. I have considered some alternatives: - Extract the OpenGL content directly (using glReadPixels), and draw this to the relevant portions of the screen bitmap. - Simulate an ALT+PrtScr, since doing this manually seems to get the content just fine. This will trash the clipboard content, though. - Try working with the DWM. Appart from Vista and Win7, this also needs to work on Win2000 and XP, so this probably isn't the way to go. Any input will be appreciated!

  • Ajax and sophisticated graphics in Java web-app

    - by EugeneP
    In my opinion WWW will sooner or later come to full-blown AJAX web-sites, so that we wouldn't have page reloads every time you click somewhere. Now I want you to ask this. What tools and frameworks can one use to make a Java Web-application running on Tomcat have AJAX functionality like "in-place, with no page reloading" table sorting by clicking on its column header, multi-tabs that enable opening at once the new screen to the user without reloading a page, saving data in the database without reloading a page, and other similar things that we do not usually see on web pages. That's all should probably be based on AJAX. But how to integrate this AJAX functionality with existing java web-frameworks, let's say Spring MVC? Or maybe there are other frameworks that better suit such needs but that can be integrated with core Spring?

  • HP Envy dv6t-7300: Disabled WiFi through button and can't enable it anymore

    - by Mateus B. Cassiano
    Well, I have a HP Envy dv6t-7300 laptop that came with a Ralink RT5390 WiFi card. Everything was working perfectly, and eventually I press the WiFi button in my keyboard to toggle the card on/off. Until today, all worked right: if the wifi was off (wifi LED amber) and I press the wifi button, after a few seconds the LED turn white and everything works. If I repeat the process, the wifi LED turn amber and the card get disabled, but now, I can't turn it on anymore. running sudo rfkill list all I get: 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no 1: hp-wifi: Wireless LAN Soft blocked: no Hard blocked: yes So, I ran sudo rfkill unblock all but nothing changed. As a side note, if I run sudo ifconfig wlan0 up, the indicator LED gets white (indicating that the card was enabled), but Ubuntu still say that the card is blocked by hardware. Extra information: the card works without issues in windows and in Ubuntu installer (booting from a live CD). I'm using the card out-of-box, using the drivers already included in Ubuntu 12.10. The module rt2800pci is loaded and working fine, not blacklisted, etc, etc. The card and the button toggle worked flawlessly until today, when I toggled it off and can't turn it on anymore... The problem is back, but in a different manner: if I don't press the wifi key a few times during the grub loading, in the login screen the wifi button will be ambar (disabled), pressing it will toggle it white (enabled) or ambar (disabled) again, but ubuntu still says that the network card was disabled by hardware and doesn't connect... In other words, if I don't press the WiFi button a few times when Ubuntu is booting, it will be stuck with the "network card was disabled by hardware" message, even if the light is white (enabled). Any clue? Maybe a error in some startup script or config file?

  • How do I export charts from Excel as graphics

    - by user83266
    I've got a series of Excel spreadsheets, each with at least one page of data and one page of a chart created from the data. I need to capture ( not regenerate from the data ) the existing chart as a web friendly image. Is this possible via Java or .Net? I know the POI stuff (Java) won't do it (or so I'm told, haven't tried it myself).

  • BSOD Code 16, artifacts all over the place (gtx 260)

    - by belinea
    I have a following, quite dated rig E8400 Core 2 Duo cpu Intel Dragontail Peak DP35DP motherboard on Intel Bearlake P35 chipset 4GB ram Geforce 260gtx Corsair 650W PSU Windows 7 64 bit The following things has happened in the last few days. I first decided to update my Nvidia drivers to the latest version. That was 4 days ago. PC worked fine for 2 days and I was able to play few games as well without any problems. Then 2 days ago a first crash happened while playing the new XCOM game. BSOD code 16. Just the blue screen, no artifacts. PC rebooted and worked well again, I continued playing this game for another 2 hours and went to sleep. Next evening I tried to play some BF3 multiplayer (use to play on LOW settings). Approx. 10 minutes into the game red/pink-ish artifacts appeared on the screen and game quit to desktop. Restarted the game and another 3-4 minutes afterwards another crash to desktop but this time followed shortly by BSOD Code 16. From that moment I started to seeing artifacts on random startups, including Windows loading screen and the BIOS itself. Windows would still load but soon enough it would BSOD on a simple task like opening a Internet browser. Today I get tons of artifacts (little small red dashes all over the screen) on BIOS, loading screen, normal Windows mode as well as safe mode. I suspect it wouldn't be drivers but I tried removing and sweeping them entirely in the safe mode. PC would still start with artifacts all over the place but would load the normal mode, just without the driver, in the default lowest resolution. As soon as proper Nvidia drivers are installed though and PC rebooted, Windows doesn't load at all as BSOD now appears on loading screen. However, again, if I go to safe mode and remove drivers, normal mode launches fine. So obviously crash happens only on high resolution. I opened my machine this morning and gave it a proper cleaning even though it wasn't heavily dusted. It didn't help and number of artifacts seems to increase with every PC restart. I write these words in safe mode, which works, but I have to look through all the red dots and dashes. I don't have built in GPU chipset so I can't try removing my Geforce card nor can I borrow A GPU from anyone else. What are my options? I was looking into getting a completely new rig around Christmas so I'm not freaking out about this. If everything points to hardware issue I may simply decide to get the new machine earlier and don't bother with fixing this one. However it would be great to learn more if this is indeed situation that has slim chances of getting sorted. I realize BSOD Code 16 is rather popular topic online but every story seems a bit different and there can be number of issues with it. Hence a new thread.

  • Java Swing custom shapes (2D Graphics)

    - by juFo
    I need to draw custom shapes. Now when a user clicks on several points on the panel I create a shape using a polygon. public void mouseClicked(MouseEvent e) { polygon.addPoint(e.getX(), e.getY()); repaint(); } But I don't know if this is the best way to draw custom shapes. It should be possible to edit a drawn shape: resize change its fill color change the stroke color copy/paste it move a single point of the polygon ... I have seen people creating an own class implementing the Shape class and using a GeneralPath. But again I have no idea if this is a good way. Now I can create my own shape with a polygon (or with a GeneralPath) but I have no clue how to attach all the edit functions to my own shape (the edit functions I mean the resize, move, etc from above). I hope somebody could show me a way to do this or maybe write a little bit of code to demonstrate this. Thanks in advance!!

  • Why should "miter" joints be slower than others?

    - by Hanno Fietz
    I'm having a graphics problem on drawing lines in Flash Player, where two lines drawn on top of each other with different thickness don't align properly if I use any other JointStyle than MITER. For pictures of the effect, and for the graphics oriented part of the question, see my post over on doctype. However, there's also a second angle on this problem, which is: why should drawing the "mitered" joints be so much slower than others? This seems to be a problem since at least FP 8, but I couldn't find any detailed info on what the problem might be. Is this just an ordinary bug that didn't get fixed yet, or is there something inherently slower about drawing these joints? For example, they seem to have something to do with square roots, but I seriously lack understanding of what this joint style thing is all about, technically. It just looks like some minor detail a graphic designer might worry about. I'm asking because I'm wondering if I can do something to mitergate, er, mitigate, the problem.

  • Animate a e.Graphics.DrawLine with arrowhead

    - by Fer
    I need to "animate" an arrow. It can go in any direction (up, down, left, right and diagonals) and the arrowhead will be at the end. It needs to appear as if it is growing from orgin to the end. To make matters more complicated it has to be in a user control so it is possible to add to the controls collection in the forms and remove it to delete it from the screen, and its background is really transparent (no color.transparent) so i can't paint the background to "clear" the previous line. I have it static already (drawn from origin to end) but i can't animate it. I tried to add a timer in the user control but I fail to get a correct algorithm to calculate the intermediate ends of the line while it is growing. Any help would be appreciated. Thanks

  • How to resize pdf graphics produced in R using Illustrator

    - by user1648516
    I am making plots in R using the pdf() command. Graphs look perfect and resize nicely in Acrobat Reader. My usual workflow includes manipulating labels etc. in Illustrator, saving as .eps for submission to publishers or inserting in Word. All works fine for single graphs. Now I am trying to combine 4 graphs into one by manually putting them together in an A4 Illustrator document. However, when I resize the standard 7x7 inches pdf graph in Illustrator to fit in one column of an A4 page (ca 3.4 inches wide), all proportions get screwed up, e.g. lines and symbols outlines become way too thick. Using pdf(..., width=3.4, height=3.4) in R messes up all the symbol and font sizes so carefully chosen to produce the original graph. Why can't I resize the graph within Illustrator the same way I can resize the pdf e.g. in Acrobat Reader?

  • R graphics plotting a linegraph with date/time horizontally along x-axis

    - by user2978586
    I want to get a linegraph in R which has Time along x and temperature along y. Originally I had the data in dd/mm/yyyy hh:mm format, with a time point every 30 minutes. https://www.dropbox.com/s/q35y1rfila0va1h/Data_logger_S65a_Ania.csv Since I couldn't find a way of reading this into R, I formatted the data to make it into dd/mm/yyyy and added a column 'time' with 1-48 for all the time points for each day https://www.dropbox.com/s/65ogxzyvuzteqxv/temp.csv This is what I have so far: temp<-read.csv("temp.csv",as.is=T) temp$date<-as.Date(temp$date, format="%d/%m/%Y") #inputting date in correct format plot(temperature ~ date, temp, type="n") #drawing a blank plot with axes, but without data lines(temp$date, temp$temperature,type="o") #type o is a line overlaid on top of points. This stacks the points up vertically, which is not what I want, and stacks all the time points (1-48) for each day all together on the same date. Any advice would be much appreciated on how to get this horizontal, and ordered by time as well as date.

  • Normalized Device Coordinates to window coordinates

    - by okoman
    I just read some stuff about the theory behind 3d graphics. As I understand it, normalized device coordinates (NDC) are coordinates that describe a point in the interval from -1 to 1 on both the horizontal and vertical axis. On the other hand window coordinates describe a point somewhere between (0,0) and (width,height) of the window. So my formula to convert a point from the NDC coordinate system to the window system would be xwin = width + xndc * 0.5 * width ywin = height + ynfv * 0.5 * height The problem now is that in the OpenGL documentation for glViewport there is an other formula: xwin = ( xndc + 1 ) * width * 0.5 + x ywin = ( yndc + 1 ) * height * 0.5 + y Now I'm wondering what I am getting wrong. Especially I'm wondering what the additional "x" and "y" mean. Hope the question isn't too "not programming related", but I thought somehow it is related to graphics programming.

  • R from java with no graphics: is it worth moving to JRI

    - by LH
    I have a system set up that's been happily running R from a java servlet, spawning processed & hooking into the process's stdin, stdout, and stderr streams, as in the second andwer to this question. After a system upgrade (that included glibc), the input is no longer reaching the R process.* Until now, 'R --vanilla --slave -f [file] ...' was working fine for me. I also have no swing dependencies right now, so I'm somewhat reluctant to add them. (I may actually not be able to add swing dependencies; am I right that using REngine automatically brings swing in? The examples import all of swing.) Are there advantages to switching to JRI? What changes would I need to make to my R script? (It currently reads from stdin and writes to stdout). I'm not finding the provided examples terribly helpful for how to use JRI in this situation. Thanks for your help & comments. *I can't even tell if the problem is data being written too soon or too late, but that's a separate issue/question; if I move to JRI I'm hoping it all becomes moot.

    A friend is wanting me to help her convert her flash based website to html. She has an embedded textbox with a scrollbar that is using a flower instead of a normal scrollbar. Avoiding the obvious question of why a user would want a non-standard element to do this task, is it possible to do this without flash?

  • Why does Mass Effect 1 run so slow on my machine if I have an XFX NVidia 9400GT video card? [closed]

    - by Papuccino1
    I so sick and tired of having my components pass the minimum requirements of a game and then I get 15 FPS on the game on everything low. Should't PC developers say 'use at least this video card for a smooth 30 FPS'? Here are my specs: Windows 7 2GB DDR2 RAM XFX Nvidia 9400gt Intel Pentium D Dual Core 2.8ghz I should be at LEAST getting 30 FPS on everything low right? Please tell me what I can do to make games run as they should, or is my video card not good for these games? Here are the recommended requirements from the official site: Recommended System Requirements for Mass Effect on the PC Operating System: Windows XP or Vista Processor: 2.6+GHZ Intel or 2.4+GHZ AMD Memory: 2 Gigabyte Ram Video Card: NVIDIA GeForce 7900 GTX or higher. ATI X1800 XL series or higher Hard Drive Space: 12 Gigabytes Sound Card: DirectX 9.0c compatible sound card and drivers – 5.1 sound card recommended My videocard is 9400GT, how is that worse than a 7900GTX? :S Edit 2: I should note, that I get poor frames when running the game in absolute BOTTOM specs. lowest resolution, no particles, etc. etc. Absolute ZERO and getting poor framerates.

  • How can I remotely tell what brand/model internal SCSI card is installed in a machine?

    - by edmicman
    I am doing some consulting work for a previous employer upgrading and migrating old servers to new hardware. There is an existing file server (HP ProLiant DL380) that has an tape backup drive connected; it is using a SCSI interface and I'm pretty sure it's using an internal SCSI card. They are upgrading to a new server hardware (HP ProLiant DL160 G6). The old server is 2U, the new one 1U and we would want to move the tape drive to the new server, too. I'm trying to figure out if the SCSI card in the old server would be able to be installed in the new one or if we'll need to source a new card; mostly I don't know for sure the height of the card and if it's low-profile enough that it would fit in the new server. There is not much of a technical resource onsite and the old server is in-use anyway so I would like to avoid making a trip in myself or trying to have someone onsite pop open the case and tell me what card is there. It's running Windows Server 2003 - is there a way to tell from say Device Manager what make and model the SCSI card might be? Or any other system diagnostic program or something that would give me hardware info like that? Thanks for any info!

  • Video card not detected in POST on initial boot.

    - by Jeff M
    I have a minor problem with my desktop computer after cleaning it out for dust. When I first boot up the computer, the video card does not get detected so I can't see anything. In POST, I'm getting the "can't detect video card" beeps. The boot sequence continues normally, just without video. However, if I restart it (using the restart button) anytime after POST, it would boot up normally. I have no reason to think that the motherboard, video card or PSU got damaged in the process. It was working fine before, works fine after resetting. Took all the necessary precautions while cleaning. On the initial boot, I can hear the video card's fan power up but immediately power down and try again one more time only to fail. After the beep, resetting gets everything running and sounding normally. I've reseated the card a couple of times and reset the BIOS but doesn't seem to help. I'm hoping I won't have to take it out and remove and reinstall everything again. Does anyone recognize these symptoms to know exactly what the problem is? My guess is that the video card isn't getting enough juice initially to be running stable to be detected. I just don't know what I did (or didn't do) to get it to be in this state. It's not a high priority thing for me at the moment, just means I have to always reset it after initially turning it on but will eventually remove everything and reinstall if it comes to that. I don't think the specs are relevant here but just in case, here's the relevant stuff: Motherboard: Gigabyte P35-DS3P Video: EVGA GeForce 8600 GTS PSU: Antec True Power Trio 650W Built ~2 years ago, still running well

  • Which Cardbus/PCMCIA -> USB card works with external hard drive?

    - by Carl
    I have an HT-Link Cardbus/PCMCIA USB 2.0 2-port card (NEC / 32-bit). My external hard drive w/USB adapter won't work with it, and it will work plugged directly into a USB port on a different laptop. (My USB ports got fried.) I got the card off E-Bay. My MP3 player works plugged into that card. The drivers for the card say "Known limitations: High Speed Isochronus, USB Composite Devices." (No other details provided.) I don't know if the hard drive adapter is "isochronous" or "composite." I've read there are problems with too little power being supplied to the drive. The cable to the drive has two USB plugs on one end, and it doesn't make any difference if I plug both of them into the Cardbus card. What card should I get? I see many different brands on E-Bay. I need one that supplies sufficient power for an external hard drive, and doesn't have any "known limitations" in the way.
