Screenshot of AS-AESCTR 1.10

A command line program for encryption and decryption of files. The program uses a 256-bit AES-256 (in CTR mode with a 128-bit random nonce).

The program uses a (built-in) key strengthening algorithm, this increases the security.

The program stores an encrypted checksum of the original file, which is verified at decryption.

The program delivers an ErrorLevel code which indicates success (0) or failure (1).

The speed is measured and the program will display the results for you when it's done.

Use the parameter "-NoPercent" to display the number of Bytes that has been processed instead of percent.

Important information: Save the downloaded program if you have information encrypted with it. I do not guarantee compatibility between different versions/revisions of the program.

Speed Reference: Approximately 56 MB/sec. (Intel Core i3-9100)

A command line program for compression and uncompression of files. The program is mainly intended as a companion program to my command line programs for encryption, to be run on compressable data before encryption and after decryption. The program applies error checking using CRC-64-ECMA. You can compress up to 128 MB of data.

Screenshot of AS-Downloader 1.0

A command line program to add/update all programs from this website into a proper (recommended) location. The recommended location to put all files from this website is in a folder named "Andreas Software" in the root of your system disk. The program takes care of most of the steps needed to add/update all programs (except for shutdown of running programs inside the folder) which includes create/wipe the folder, download the correct Zip file (depending on your language) with all programs, uncompress them and create a shortcut to the folder on the desktop.

Security information: Some antivirus programs interpret this procedure (downloading a bunch of unsigned EXE files from Internet and writing them to disk) as suspicious and may block it as a threat. For maximum compatibility, you can temporarily disable your protection before using AS-Downloader.

Instructions for AS-Downloader 1.0

Optional parameters:

• "/AlsoWipeSettings" (Also wipe all INI/PREF/BIN files.)
• "/NoShortcut" (Don't create a shortcut on the desktop.)
• "/NoPause" (Don't ask for the [ENTER] key to exit.)
• "/English" (Force downloading of the English Zip file.)

Screenshot of AS-Circle Image 1.10

This command line program loads a JPEG image and creates a circle image with an alpha channel and saves it as a 32-bit PNG image. The program does this with Anti-Alias to get smooth edges. Worth noting is that the program does not remove the other information in the image, if you would open the image in a program that does not use the alpha channel the whole image will show up without the circle.

Screenshot of AS-CC 2.10

A program which can change the gamma values for the components red, green and blue to get the environment you want. The program can also offset the color components to better control the grayscales. Windows has a built-in protection which makes that a program won't be able to make too big changes, I have included a REG file which lets you disable this protection (restart required).

Information: The program only creates and loads the gamma table, there is no functionality of making the changes persistent. If you want the changes to be persistent - create a shortcut to the program (with the parameters preset) in Startup and also make sure that no other programs modifies the gamma table. However, there are several events in Windows that can reset the gamma table, so it may be a good idea to also have a shortcut to the program (with the parameters preset) on the desktop. If your graphics card has functions for setting gamma and offset, it is better to use these, but if they are missing, this program is at least better than nothing.

Instructions for AS-CC 2.10

Parameters:

• "/Monitor=1 to 999" (Selects monitor.)
• "/AGamma=1 to 100" (Sets all components to this value.)
• "/RGamma=1 to 100"
• "/GGamma=1 to 100"
• "/BGamma=1 to 100"
• "/AOffset=+/-1 to 48" (Sets all components to this value.)
• "/ROffset=+/-1 to 48"
• "/GOffset=+/-1 to 48"
• "/BOffset=+/-1 to 48"
• "/Silent" (Silent mode, no message box.)

E.g. Run => "C:\Andreas Software\AS-CC.EXE" "/Monitor=1" "/RGamma=80" "/GGamma=70" "/BGamma=60" "/ROffset=+16" "/GOffset=+4" "/BOffset=-16" => OK.

Note: If you don't see any difference when using this program it means that your graphics card doesn't support this feature.

Screenshot of AS-Scale2X 1.0

A command line program to up-scale "pixel-art" with rounding of the squares. You enter a value from 1 (2 × up-scaling) to 8 (256 × up-scaling). The program deals with images in the BMP format.

The program calculates the speed, in generated megapixels / second.

Example

Input file

Pixel resize

Output file

Use the parameter "-NF" to not apply the filter. The result of using this parameter will be "pixel resize".

You can also download AS-EPX 1.0 which uses the EPX algorithm but with optimizations made for the Scale2X algorithm. The result is a slightly faster EPX/Scale2X.

Screenshot of AS-Scale3X 1.0

A command line program to up-scale "pixel-art" with rounding of the squares. You enter a value from 1 (3 × up-scaling) to 6 (729 × up-scaling). The program deals with images in the BMP format.

The program calculates the speed, in generated megapixels / second.

Example

Input file

Pixel resize

Output file

Use the parameter "-NF" to not apply the filter. The result of using this parameter will be "pixel resize".

The Scale3X algorithm can round the squares even more (than the Scale2X algorithm). See Lonely_Pixel_Scale2X.PNG and Lonely_Pixel_Scale3X.PNG.

Use the parameter "-NIF" to not invert the filter.

Use the parameter "-NIBV" to not invert the blend value.

Use the parameter "-NB" to not use blending of colors.

Screenshot of AS-Threshold Filter 1.10

A command line program to apply a threshold filter on an image. A threshold filter is a very simple filter that usually makes sure that an image only contains two colors. The program lets you choose these two colors and adjust the threshold value as needed. The program deals with images in the BMP format.

Use the parameter "-FC" to allow four colors or "-EC" to allow eight colors. The remaining two or six colors are calculated automatically and the threshold value is ignored when using any of these parameters.

Use the parameter "-FR" to allow the full color range from color one to color two. The threshold value is ignored also when using this parameter.

Use the parameter "-SC" to swap the two colors with each other.

Hex colors: Abbreviated hex colors are not supported.

Screenshot of AS-EAN13 1.0

A command line program to convert twelve digits into a barcode image in the EAN-13 format. The program saves the image in BMP format.

The image is drawn in a relatively high resolution, so you can print it with a higher DPI setting and still get high quality.

Use the parameter "-H" to draw the image in a higher resolution. The image then becomes twice as large.

See EAN13.PNG (1,080 × 644 pixels) and EAN13_H.PNG (2,160 × 1,288 pixels).

You can also download AS-EAN8 1.0 to convert seven digits into a barcode image in the EAN-8 format.

A suite containing two programs that can play a melody string and two programs that can play a specified frequency (in Hz) in a specified length (in milliseconds). The Sine-programs uses the sound card (in form of sine waves) and the Square-programs uses the sound card (in form of square waves). Can e.g. be used to announce something in a program, script or in a batch file. The programs shows nothing on the screen and when the sound has been played they are closing automatically.

Use the parameter "/KeepWAV" to keep the generated audio file "Audio.WAV" which is located in the same folder as the programs. (These programs needs write access rights to the folder where the EXE files are located.)

Specifications for generated audio files:

• Samples per second: 44,100.
• Bits per sample: 16.
• Channels: 2 (Stereo).
• Format: PCM (Pulse Code Modulation).

(These values are commonly called CD quality.)
