Bitmap | Easy low-level access to individual pixels | Editor library

You can set the value of the Graphics.InterpolationMode property to the interpolation method that you want to use. This must be done before you call DrawImage.

You should not be drawing on the Form's Canvas from outside of its OnPaint event at all. All of the drawing should be in the OnPaint event only. Have your timer save the desired information into variables that the Form can access, and then Invalidate() the Form, and let its OnPaint event draw the image using the latest saved information.

Alternatively, simply display your BMP inside a TImage control, and then have the timer set that control's Left/Top/Width/Height properties as needed. Let the TImage handle the drawing of the image for you.

You missed to set the alignment. By default OpenGL assumes that the start of each row of the raster is aligned to 4 bytes. This is because the GL_UNPACK_ALIGNMENT parameter by default is 4. Each row in the raster has 5 bytes (40 / 8 = 5). Therefore you need to change the alignment to 1:

If you want to stop the music, when the installer is closing, just use the same code you already have in StopButtonClick from DeinitializeSetup:

BitBlt is super fast, but it will copy the entire bitmap.

Actually, no: BitBlt allows you to copy only a rectangular part of the source, specified using the x1, y1, cx, and cy parameters.

However, the same width and height are used for the source and the destination rectangles, so BitBlt cannot be used to stretch (or scale) the part you copy.

StretchBlt lets you do this, though.

With regards to the image analysis resolution, the documentation of ImageAnalysis.Builder.setTargetResolution() states that:

The maximum available resolution that could be selected for an ImageAnalysis is limited to be under 1080p.

So setting a size of 2560x800 won't work as you expect. In return CameraX seems to be selecting the maximum ImageAnalysis resolution that has the same aspect ratio you requested (2560/800 = 1280/400).

EDIT: BETTER WAY

INSTEAD OF EDITING THE STRING IN THE SERVER WE SHOULD ENCODE IN ANDROID THIS WAY

Base64.encodeToString(bytes, Base64.NO_WRAP);

AND GET IT IN THE SERVER THE USUAL WAY WITHOUT EDITING THE STRING

java.util.Base64.getMimeDecoder().decode(yourByteArray);

PREVIOUS WAY:

I just had to edit the String that i was getting in the server by removing the quotes surrounding it with img.substring(1, img.length() - 1) and the \n with img.replace("\\n", "").

The result code in the server is like this:

You cannot access the Context in recycler adapter directly. Get it by a View object. In your case either you pass the context through the constructor from an activity like:-

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:
