OpenAsPicture, SaveAsPicture of methods in FolderItem class depend on a monitor depth.
Then, I made extension plugin of FolderItem class which could read/write various image formats with depth, such as, 32, 16, 8....
- Can read image format with GraphicsImporter after QuickTime 2.5.
- Can read the postertime image of QuickTime Movie.
- Can read PICT resource.
- Can store picture by PICT, JPEG (can establish compression) , TIFF, Photoshop format.
- Can set up memory domain for picture.
Set up memory domain for picture
mic_PictureUtil_UseTempMem( UseTemp as Integer )
UseTemp：
0: Try making picture in application heap. if it was failure, try in temporary.
1: Try making picture in temporary. if it was failure, try in application heap.
2: Try making picture in application heap. if it was failure, return nil.
3: Try making picture in temporary. if it was failure, return nil.
Open as picture with depth
f.OpenAsGiPicture(depth as integer) as picture
depth = 32, 16, 8, 4, 2, or 1
f: FolderItem
Read PICT resource
f.OpenAsMicPICS(resID as integer, depth as integer) as picture
depth = 32, 16, 8, 4, 2, or 1
f: FolderItem
Save as PICT format
f.SaveAsMicPICT(p as picture, depth as integer) as integer
depth = 32 (Only 32 bits in this version)
if return value is not 0, it is error.
f: FolderItem
Save as JPEG format
f.SaveAsMicJPEG(p as picture, depth as integer, quality as integer) as integer
depth = 32, 16, 8, 4, 2, or 1
f: FolderItem
if return value is not 0, it is error.
quality：
minimum valid value = 0
low-quality reproduction = 256
normal-quality repro = 512
high-quality repro =768
maximum-quality repro =1023
lossless-quality repro = 1024
Save as TIFF format
f.SaveAsMicTIFF(p as picture, depth as integer) as integer
depth = 32 (Only 32 bits in this version)
f: FolderItem
if return value is not 0, it is error.
Save as Photoshop format
f.SaveAsMic8BPS(p as picture, depth as integer) as integer
depth = 32 (Only 32 bits in this version)
