I have added a textbox annotation to an image, but it is difficult to read the text if I don't use a background. If I do use a background, I obscure the image. I have examined one possible solution which is inelegant:
Add transparency to the annotation background. This is not built-in and requires a kluge.
One possible alternative which I would like to try is to add an outline to the text. Anyone know how to do that?
EDIT
I should have been more specific by what I had meant by "add an outline to the text". I meant Microsoft Word's definition of an outline.
Based on your edit, you don't just want a text box. I am not sure how to fix the text but based on the answer to my question here, you can set the box transparency.
plot(sin(rand(10)))
a = annotation('textbox', [0.5 0.5 0.1 0.1], 'String', 'Some Random Text');
b = annotation('textbox', get(a,'Position'));
set(b, 'BackgroundColor', [0 0.5 0]);
set(b, 'FaceAlpha', 0.5);
uistack(a,'top')
Here is an example:

I've made a simple shape editor. I can change colors (used to fill shapes) by click on buttons in a menu bar. The disadvangate of this solving is the fact that the numbers of colors are so restricted. I can't find a better solution for my program. Can somebody help me and give me an idea how can I improve it? I thought about color palette, but I have no idea how can I do this.
The image:
("Aktywny kolor" means active colors, and there is the list of colors below, which I can use)
You would need to use a color picker where the colors are distributed on many pixels and not on a very small set of color names. Since you are using applet, you might want to download an already made color picker compatible with your environment, or you might want to write your own, depending on whether the things you find meet your expectations.
Has anyone figured out a way to dynamically mutate text on the screen without triggering a render?
A large part of my screen utilizes setNativeProps for moving parts, meaning that the animations become lagged despite using shouldComponentUpdate. I would like to use the Text tag instead of the TextInput tag workaround suggested in this post for stylistic reasons.
Best case scenario is a workaround that involves setNaiveProps as it would follow the pattern of the rest of the screen; however, I currently plan to render all the numbers 0-9 on the screen an move them into place at the moment, so any help would be greatly appreciated!
As it turns out, you can actually format TextInputs the same exact way as Text elements (from what I have tested). For placing text horizontally, you have to set the width (something I had trouble with before). For those still interested in the original question however, you can nest TextInputs inside of a Text Element (one per text element because there is no justification and it automatically places them in a row). Styling applied to the Text Element will apply to the TextInput.
The idea is like the inverse of Ishihara test (http://www.colour-blindness.com/colour-blindness-tests/ishihara-colour-test-plates/).
I want to create with GIMP an image that showing something and then if I add a color layer, for exemple green glasses, then I see something new appearing.
I've searching far in Google and so but didn't found anything. Do you know how would I make this?
The Ishihara tests use the principle of combining things color blind persons cannot differentiate.
Coloured glass filters will only remove other colours from what you see. They don't add something. Therefor it is not possible to create a digital image that contains no information unless seen through a colour filter.
The only thing you can do is overlap your "hidden" information with high contrast colour noise.
Like here:
Using the glasses / filter only improves the visibility. The information is not added. It was always there.
currently I produce dynamically this document with Python Report Labs… to produce pdf documents.
Now, I would like try to produce this document with Tex / Latex / ConTeXt…
I've some questions :
how can I make the layout ?
how can I make header background color ?
how can I define my custom title (with blue box) ?
what is the better choice for my project : Latex or ConTeXt ?
What package I need to use ?
geometry ?
fancyhdr ?
Have you some example ? some resource ?
Yesterday, I've read many many documentation… and I don't found a solution / example for my questions.
Some useful packages apart from the fancyhdr you already mentioned are:
titlesec for more control over your section titles
booktabs for more control over table layout
PGF/TikZ for the graphics in your document, i.e., the page turn effect in the corner and maybe the blue boxes (although that might be considered a bit overkill :))
memoir for more control over your document layout, but the package is more book-oriented than you need probably
koma-script might be a good alternative for memoir but I'm not familiar with it so I don't know about its weaknesses
This is list is not exhaustive and I am not experienced enough in this kind of typesetting meets lay-out stuff to be of much help, but these are packages that come to my mind given your problem :).
Using inputenc there shouldn't be a problem typesetting Russian text.
Maybe the actual process will be easier in ConTeXt, it is more oriented towards control over your typesetting but I'm not familiar with it.
Good luck!
I'd certainly do this kind of think in Context rather than Latex: Context permits grid layout, and allows you to define layers for putting text and other graphics on top of background graphics. But as Pieter says, you could try using TikZ to do this with Latex.
Unicode is no barrier to regular Latex or Context: with either, just specify that you want to use utf-8 as input encoding.
If you do use Latex, don't have headers or footers, and allocate no vertical space for them either.
With Context:
how can I make the layout? — Use grid layout.
how can I make header background color? — Use \setupbackground
how can I define my custom title (with blue box) ? — I don't understand what you want to do here.
Everything you need to do this, except grid mode and how to put graphics in the background, is documented in Context an excursion. Grid mode is explained in the Context manual. Layers are a bit tricky to get to grips with, but Layers in the Context wiki is a good place to start.
With titlesec and color packages use this in LaTeX head (before \begin{document})
\usepackage{titlesec}
\usepackage{color}
% Colors
\definecolor{textcolor}{rgb}{.90,.95,1}
\definecolor{boxcolor}{rgb}{.94,.97,1}
% Header style
\titleformat{\section}
{\color{textcolor}\normalfont\Large\bfseries}
{}{1em}{{\color{boxcolor}\rule{0.35cm}{0.35cm}}\quad}
to make the blue box and change header color, font and remove numbering.
How do you determine the length of a string of text in Arial Bold font, and then center it in VB6?
We are not using a "label" or "picture box" to print the text to the screen. We are sizing the text on the fly, and allowing the user to scale the size of our application to their liking. We write the text to screen using code.
One way is to have a hidden picture box and setup the font specs of that picture box the way you want.
Then use the TextHeight and TextWidth methods of the PictureBox to take your measurements. The Units will be in whatever scalemode the Picture Box is set to.
If you are printing directly to the printer or form then just set your font FIRST then take your measurements.
To center it
MyText = "Hello World"
<displayarea>.FontName = "Arial"
<displayarea>.FontSize = 14
<displayarea>.FontBold = True
TextWidth = <displayarea>.TextWidth(MyText)
TextLeftCoordinate = <displayarea>.ScaleLeft+<displayarea>.ScaleWidth/2-TextWidth/2
<displayarea>.CurrentX = TextLeftCoordinate
<displayarea>.Print MyText
Substitute displayarea with whatever object you are using.
Based on your updated answer note that the hidden picture box suggestion isn't used to print. It is only get text measurement. However you are printing directly to the form so you just need to use the code example above.
I can't remember the specifics (it's been about 3 years since I last used VB 6), but there's a method on Form called something like "MeasureString". It takes the string, and measures it according to the font settings of the form.
Also, here's a comment posted by Jason Lepack in case I've misunderstood and over-complicated your requirements:
"Labels usually have an alignment property. If you set it to align to center then, regardless of the font face it should center in the label".
There are Win32 GDI functions you can invoke: see for example GetTextExtentPoint32 at http://msdn.microsoft.com/en-us/library/ms534223(VS.85).aspx
Your best option may be Form.TextWidth, which appears to return the width of a string in twips. I've just taken this approach in order to dynamically size a button based on the length of the label that needs to appear inside it.
There is also a corresponding function called Form.TextHeight which would allow you to do the same thing in the vertical dimension.
Make sure that you set the Font property of the form to match the Font property of the control you're intending to measure the text for, otherwise you'll get incorrect results.
