  • CGContext rotation

    - by kasperjj
    I have a 100x100 pixel image that I want to draw at various angles rotated around the center of the image. The following code works, but rotates around the original origo of the coordinate system (upper left hand corner) and not the translated location. Thus the image is not rotated around itself but around the upper left corner of the screen. CGContextRef context = UIGraphicsGetCurrentContext(); CGContextTranslateCTM(context, -50, -50); CGContextRotateCTM (context, 0.3); CGContextTranslateCTM(context,768/2,1024/2); [image drawAtPoint:CGPointMake(0,0)]; I tried doing the same using CGAffineTransform, but got the same results.

  • Semi-transparent PNG Image on transparent Form

    - by Marco Bruggmann
    Hello, I have a problem dealing with transparent images on transparent Forms. I have been trying and looking for a solution but nothing useful came up. The problem is: I have a Form, this Form has a Panel and the Panel has a PictureBox. Form and Panel are transparent. Now, if the image of the PictureBox has no semi-transparent it works. But if there is a gradient transparency then the "transparent color" is shown. I need the Panel and the PictureBox, so the PerPixelAlpha does not apply for this case. The Form will also have more Controls that should be visible and non transparent (just the PNG image should be transparent). The image below shows: [Left] When the Panel is not transparent. [Center] When the Panel is transparent. [Right] Desired effect (done with PerPixelAlpha). http://www.freeimagehosting.net/uploads/3937fe974d.jpg THX Marco

  • PopupWindow with GridView - Trouble with inflating view

    - by k_day
    I am having an issue while trying to use a GridView in a PopupWindow. On my Activity's onCreate method, I am inflating a gridview from xml as follows: LayoutInflater inflater = (LayoutInflater)this.getSystemService (Context.LAYOUT_INFLATER_SERVICE); final GridView popupview = (GridView) inflater.inflate (R.layout.gridviewpopup, null, false); popupview.setAdapter(new ImageAdapter(this)); would like this GridView to popup on a button click. Also inside of my activity's onCreate, I have: final Button addButton = (Button) findViewById(R.id.add); addButton.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { PopupWindow mwindow = new PopupWindow(popupview, 100, 100); mwindow.showAtLocation(findViewById(R.id.main), Gravity.CENTER, 100, 100); mwindow.setFocusable(true); } }); On button click, I am throwing a ClassCastException from GridView.onMeasure(int, int). Can anyone please explain to me what I am doing wrong?

  • How to paint fully transparent pixels/points in P2D mode?

    - by netzwerg
    According to the Processing Reference, stroke(gray, alpha) allows to set the color and opacity of the stroke. With the default color mode, an alpha value of 255 denotes full opacity, while a value of 0 should correspond to complete transparency. While this works with the (default) JAVA2D renderer, I can't seem to paint fully transparent points in P2D mode. This code clearly renders a pixel at the center of the canvas, even though the alpha value is set to 0 (fully transparent): public class Transparency extends PApplet { @Override public void setup() { size(200, 200, P2D); } @Override public void draw() { stroke(0, 0); point(width / 2, height / 2); } public static void main(String[] args) { PApplet.main(new String[] { Transparency.class.getSimpleName() }); } } What's wrong here?

  • Tutorial for Quick Look Generator for Mac

    - by vgm64
    I've checked out Apple's Quick Look Programming Guide: Introduction to Quick Look page in the Mac Dev Center, but as a more of a science programmer rather than an Apple programmer, it is a little over my head (but I could get through it in a weekend if I bash my head against it long enough). Does anyone know of a good basic Quick Look Generators tutorial that is simple enough for someone with only very modest experience with Xcode? For those that are curious, I have a filetype called .evt that has an xml header and then binary info after the header. I'm trying to write a generator to display the xml header. There's no application bundle that it belongs to. Thanks!

  • Windows Forms Autosizing in .NET

    - by mcoolbeth
    My C# project contains a form. There are some controls across the top of the form and some controls across the bottom of the form, as well as a FlowLayoutPanel in the center, all of which have been placed with the Visual Studio Form Designer. During runtime, controls are dynamically added to and removed from the FlowLayoutPanel, and both the panel and the form itself are configured to automatically fit the size of they're contents. However, since some controls were placed with the designer above and below the FlowLayoutPanel, the desired resizing fails to take place when new controls are added to the FlowLayoutPanel. Does anybody know of a convenient remedy for this problem?

  • Safari box shadow inset support

    - by codedude
    I have a box in one of my websites that has a these property: -moz-box-shadow:inset 0 0 50px #ecf4de; -webkit-box-shadow:inset 0 0 50px #ecf4de; box-shadow:inset 0 0 50px #ecf4de; This gives the box a nice gradient towards the center. However, Safari does not support the "inset" property and IE doesn't support box-shadow at all. I can't use an image for this because the height of this box changes for each situation. I don't want to use 3 images, (one for the top, a repeating one for the middle and one for the bottom), as this can get very messy code. So what I'm asking is if there is any way to produce the box shadow in all browsers.

  • Sans-serif math with latex in matplotlib

    - by Morgoth
    The following script: import matplotlib matplotlib.use('Agg') import matplotlib.pyplot as mpl mpl.rc('font', family='sans-serif') mpl.rc('text', usetex=True) fig = mpl.figure() ax = fig.add_subplot(1,1,1) ax.text(0.2,0.5,r"Math font: $451^\circ$") ax.text(0.2,0.7,r"Normal font (except for degree symbol): 451$^\circ$") fig.savefig('test.png') is an attempt to use a sans-serif font in matplotlib with LaTeX. The issue is that the math font is still a serif font (as indicated by the axis numbers, and as demonstrated by the labels in the center). Is there a way to set the math font to also be sans-serif?

  • How to add handler in dynamic datatemplate

    - by Phillip Ngan
    I am successfully declaring a data template in a code behind as follows: private static DataTemplate CreateTemplate(string sortMemberPath, HorizontalAlignment horzAlignment) { const string xamlFormat = "<DataTemplate xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" >" + "<StackPanel > " + " <TextBlock Margin=\"2,0\" VerticalAlignment=\"Center\" HorizontalAlignment=\"_HALIGNMENT_\" " + " Text=\"hello there\"> " + " </TextBlock> " + "</StackPanel>" + "</DataTemplate>"; return (DataTemplate) XamlReader.Load(xamlReturned); } But now I want to add a size changed handler by changing the line: + "<StackPanel > " to + "<StackPanel SizeChanged="SizeChangedHandler" > " I have the method "SizeChangedHandler" declared in the code behind. This results in a xaml parse error when the control attempts to load at runtime. I suspect that it can't find the handler "SizeChangedHandler". How can I specify this handler so that the xaml parser is happy.
