In your template you're calling your method editData(item) and you're passing variable item as your parameter. But in your template there is no such thing defined - I assume (without looking at the rest of your code) that you wanted to write editData(forecast) instead. This will pass the forecast variable defined in your *ngFor directive.

I am currently a bit stuck! Lets say, have a grid of shapes (nested For-Loop) and I want to use a wave to animate it. The wave should have an offset. So far, i can achieve it. Currently the offset affects the Y-axis … But how can I manage to have a RADIAL offset – you know – like the clock hand, or a radar line… I really would like the offset to start from (width/2, height/2) – and then walks around clockwise.

Right now, you're defining the size of the ellipses based on a transformation of sin(y). A transformation means it looks like a * sin(b * y + c) + d, and in this case you have

a = tileSize / 2
b = 300 / 60 = 5
c = frameCount
d = tileSize / 2

If you want to do a different pattern, you need to use a transformation of sin(theta) where theta is the "angle" of the dot (I put "angle" in quotes because it's really the angle from the vector from the center to the dot and some reference vector).

I suggest using the atan2() function.

QUESTION

differences in bitmap or rasterized font bitmaps and text display on 3.5" TFT LCD

Asked 2021-Jun-12 at 16:19

I am using a 3.5: TFT LCD display with an Arduino Uno and the library from the manufacturer, the KeDei TFT library. The library came with a bitmap font table that is huge for the small amount of memory of an Arduino Uno so I've been looking for alternatives.

What I am running into is that there doesn't seem to be a standard representation and some of the bitmap font tables I've found work fine and others display as strange doodles and marks or they display upside down or they display with letters flipped. After writing a simple application to display some of the characters, I finally realized that different bitmaps use different character orientations.

My question

What are the rules or standards or expected representations for the bit data for bitmap fonts? Why do there seem to be several different text character orientations used with bitmap fonts?

Thoughts about the question

Are these due to different target devices such as a Windows display driver or a Linux display driver versus a bare metal Arduino TFT LCD display driver?

What is the criteria used to determine a particular bitmap font representation as a series of unsigned char values? Are different types of raster devices such as a TFT LCD display and its controller have a different sequence of bits when drawing on the display surface by setting pixel colors?

What other possible bitmap font representations requiring a transformation which my version of the library currently doesn't offer, are there?

Is there some method other than the approach I'm using to determine what transformation is needed? I currently plug the bitmap font table into a test program and print out a set of characters to see how it looks and then fine tune the transformation by testing with the Arduino and the TFT LCD screen.

My experience thus far

Raster or bitmap fonts are represented in a number of different ways and there are bitmap font file standards that have been developed for both Linux and Windows. However raw data representation of bitmap fonts in programming language source code seems to vary depending on:

the memory architecture of the target computer,
the architecture and communication pathways to the display controller,
character glyph height and width in pixels and
the amount of memory for bitmap storage and what measures are taken to make that as small as possible.

A brief overview of bitmap fonts

A generic bitmap is a block of data in which individual bits are used to indicate a state of either on or off. One use of a bitmap is to store image data. Character glyphs can be created and stored as a collection of images, one for each character in the character set, so using a bitmap to encode and store each character image is a natural fit.

Bitmap fonts are bitmaps used to indicate how to display or print characters by turning on or off pixels or printing or not printing dots on a page. See Wikipedia Bitmap fonts

A bitmap font is one that stores each glyph as an array of pixels (that is, a bitmap). It is less commonly known as a raster font or a pixel font. Bitmap fonts are simply collections of raster images of glyphs. For each variant of the font, there is a complete set of glyph images, with each set containing an image for each character. For example, if a font has three sizes, and any combination of bold and italic, then there must be 12 complete sets of images.

A brief history of using bitmap fonts

The earliest user interface terminals such as teletype terminals used dot matrix printer mechanisms to print on rolls of paper. With the development of Cathode Ray Tube terminals bitmap fonts were readily transferable to that technology as dots of luminescence turned on and off by a scanning electron gun.

Earliest bitmap fonts were of a fixed height and width with the bitmap acting as a kind of stamp or pattern to print characters on the output medium, paper or display tube, with a fixed line height and a fixed line width such as the 80 columns and 24 lines of the DEC VT-100 terminal.

With increasing processing power, a more sophisticated typographical approach became available with vector fonts used to improve displayed text quality and provide improved scaling while also reducing memory required to describe the character glyphs.

In addition, while a matrix of dots or pixels worked fairly well for languages such as English, written languages with complex glyph forms were poorly served by bitmap fonts.

Representation of bitmap fonts in source code

There are a number of bitmap font file formats which provide a way to represent a bitmap font in a device independent description. For an example see Wikipedia topic - Glyph Bitmap Distribution Format

The Glyph Bitmap Distribution Format (BDF) by Adobe is a file format for storing bitmap fonts. The content takes the form of a text file intended to be human- and computer-readable. BDF is typically used in Unix X Window environments. It has largely been replaced by the PCF font format which is somewhat more efficient, and by scalable fonts such as OpenType and TrueType fonts.

Other bitmap standards such as XBM, Wikipedia topic - X BitMap, or XPM, Wikipedia topic - X PixMap, are source code components that describe bitmaps however many of these are not meant for bitmap fonts specifically but rather other graphical images such as icons, cursors, etc.

As bitmap fonts are an older format many times bitmap fonts are wrapped within another font standard such as TrueType in order to be compatible with the standard font subsystems of modern operating systems such as Linux and Windows.

However embedded systems that are running on the bare metal or using an RTOS will normally need the raw bitmap character image data in the form similar to the XBM format. See Encyclopedia of Graphics File Formats which has this example:

Following is an example of a 16x16 bitmap stored using both its X10 and X11 variations. Note that each array contains exactly the same data, but is stored using different data word types:

CABasicAnimation reverse from current position (like progress bar animation)

Asked 2021-Jun-08 at 07:04

I am using a circle (UIBezierPath) in my app as a mini progress bar. One problem I have is that I am only able to animate the circle once in one direction only. Let say I have the circle drawn to 80% and I want to shrink it down to 60%, the whole circle is re-drawn which is not what I want.

When using a progress bar, if you reduce the current displayed percentage, the entire bar is not redrawn, the bar simply shrinks down in size from it's current position to the new percentage, that is what I want with my circle layer.

That's normal behavior since you are using UIBezierPath(arcCenter:radius:startAngle:endAngle:clockwise:). You don't tell your path to go back to center.

Instead, draw it yourself.

QUESTION

Distinguish similar RGB pixels from noisey background?

Asked 2021-Jun-04 at 08:45

Context: I am trying to find the directional heading from a small image of a compass. Directional heading meaning if the red (north) point is 90 degrees counter-clockwise from the top, the viewer is facing East, 180 degrees is south, 270 is west, 0 is north. etc. I understand there are limitations with such a small blurry image but I'd like to be as accurate as possible. The compass is overlaid on street view imagery meaning the background is noisy and unpredictable.

The first strategy I thought of was to find the red pixel that is furthest away from the center and calculate the directional heading from that. The math is simple enough.

The tough part for me is differentiating the red pixels from everything else. Especially because almost any color could be in the background.

My first thought was to black out the completely transparent parts to eliminate the everything but the white transparent ring and the tips of the compass.

True Compass Values: 35.9901, 84.8366, 104.4101

These values are taken from the source code.

I then used this solution to find the closest RGB value to a user given list of colors. After calibrating the list of colors I was able to create a list that found some of the compass's inner most pixels. This yielded the correct result within +/- 3 degrees. However, when I tried altering the list to include every pixel of the red compass tip, there would be background pixels that would be registered as "red" and therefore mess up the calculation.

I have manually found the end of the tip using this tool and the result always ends up within +/- 1 degree ( .5 in most cases ) so I hope this should be possible

The original RGB value of the red in the compass is (184, 42, 42) and (204, 47, 48) but the images are from screenshots of a video which results in the tip/edge pixels being blurred and blackish/greyish.

Is there a better way of going about this than the closest_color() method? If so, what, if not, how can I calibrate a list of colors that will work?

If you don't have hard time constraints (e.g. live detection from video), and willing to switch to NumPy, OpenCV, and scikit-image, you might use template matching. You can derive quite a good template (and mask) from the image of the needle you provided. In some loop, you'll iterate angles from 0° to 360° with a desired resolution – the finer the longer takes the whole procedure – and perform the template matching. For each angle, you save the value of the best match, and finally search for the best score over all angles.

That'd be my code:
