TwainImageInfoMBS.BitsPerPixel as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

The number of bits in each image pixel (or bit depth).

This value is invariant across the image. 24-bit R-G-B has BitsPerPixel = 24. 40-bit C-M-Y-K has BitsPerPixel=40. 8-bit Grayscale has BitsPerPixel = 8. Black and White has BitsPerPixel = 1.

TwainImageInfoMBS.Compression as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

The compression method used to process the data being transferred.

Default is no compression.
(plugin currently only supports no compression)

TwainImageInfoMBS.ImageLength as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

How tall/long, in pixels, the image to be transferred is.

If the Source doesn't know, set this field to -1 (hand scanners may do this).
-1 can only be used if the application has set ICAP_UNDEFINEDIMAGESIZE to TRUE.
(the plugin doesn't support undefined image size)

TwainImageInfoMBS.ImageWidth as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

How wide, in pixels, the entire image to be transferred is.

If the Source doesn't know, set this field to -1 (hand scanners may do this).
-1 can only be used if the application has set ICAP_UNDEFINEDIMAGESIZE to TRUE.
(the plugin doesn't support undefined image size)

TwainImageInfoMBS.PixelType as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

This is the highest categorization for how the data being transferred should be interpreted by the application.

This is how the application can tell if the data is Black and White, Grayscale, or Color. Currently, the only color type defined is "tri-stimulus", or color described by three characteristics. Most popular color description methods use tri- stimulus descriptors. For simplicity, the constant used to identify tri-stimulus color is called TWPT_RBG, for R-G-B color. There is no default for this value. Fill this field with the appropriate TWPT_xxxx constant.

The plugin does currently only support RGB, GRAY, BW and PALETTE.

TwainImageInfoMBS.Planar as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

Whether image is planar.

If SamplesPerPixel > 1, indicates whether the samples follow one another on a pixel-by-pixel basis (R-G-B-R-G-B-R-G-B...) as is common with a one-pass scanner or all the pixels for each sample are grouped together (complete group of R, complete group of G, complete group of B) as is common with a three-pass scanner. If the pixel-by-pixel method (also known as "chunky") is used, the Source should set Planar = false. If the grouped method (also called "planar") is used, the Source should set Planar = true.

TwainImageInfoMBS.RowBytes as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.5	✅ Yes	✅ Yes	❌ No	✅ Yes	All

The number of bytes in a row.

This is not exactly the value as you may expect as Twain needs some rounding.

TwainImageInfoMBS.SamplesPerPixel as Integer

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	Twain	MBS Picture Plugin	12.2	✅ Yes	✅ Yes	❌ No	✅ Yes	All

The number of samples being returned.

For R-G-B, this field would be set to 3. For C-M-Y-K, 4. For Grayscale or Black and White, 1.
