sanselan-0.97

个人使用场景：识别图片是否cmyk，我的另外一个资源是把图片从rgb转成cmyk public boolean judgeImgFormatIfCmyk() { boolean back = false; try { org.apache.sanselan.ImageInfo img = Sanselan.getImageInfo(file); if(img.getColorType() == org.apache.sanselan.ImageInfo.COLOR_TYPE_CMYK) { //这家伙是cmyk模式滴 back = true; } } catch (ImageReadException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return back; }

ISO_v2_300_eci.zip

个人用到的场景：rgb图片转cmyk public String rgbToCmyk(String destpath,String extend) { String back = "Y"; try { BufferedImage rgbImage = ImageIO.read(file); BufferedImage cmykImage = null; // InputStream input = new FileInputStream(new File("C:/Users/lenovo/Desktop/ISOcoated_v2_300_eci.icc")); // ColorSpace cpace = new ICC_ColorSpace(ICC_Profile.getInstance(input)); ColorSpace cpace = new ICC_ColorSpace(ICC_Profile.getInstance(ThumbnailatorImageUtil.class.getClassLoader().getResourceAsStream("ISOcoated_v2_300_eci.icc"))); ColorConvertOp op = new ColorConvertOp(rgbImage.getColorModel().getColorSpace(), cpace, null); cmykImage = op.filter(rgbImage, null); JAI.create("filestore", cmykImage, destpath, "TIFF"); System.out.println("-------rgbToCmyk完成------"); } catch (IOException e) { e.printStackTrace(); } return back; } public static void main(String[] args) { ThumbnailatorImageUtil img = new ThumbnailatorImageUtil("C:\\Users\\lenovo\\Desktop\\1.jpg"); img.rgbToCmyk("C:\\Users\\lenovo\\Desktop\\22.jpg",""); //img.compressToDefineSize("C:\\Users\\lenovo\\Desktop\\2.jpg", 2048,0.99); }

GetImgExtraInfo.java

介绍了两种方式获取图片的拓展信息，简单获取可以使用ImageInfo，获取更多内容信息可以使用JpegMetadataReader.readMetadata(jpegFile) 简单获取结果 Format Details: Jpeg/DCM Bits Per Pixel: 24 Comments: 0 Format: JPEG Format Name: JPEG (Joint Photographic Experts Group) Format Compression Algorithm: JPEG Height: 2670 MimeType: image/jpeg Number Of Images: 1 Physical Height Dpi: 300 Physical Height Inch: 8.9 Physical Width Dpi: 300 Physical Width Inch: 13.333333 Width: 4000 Is Progressive: false Is Transparent: false Color Type: YCbCr Uses Palette: false 复杂： Compression Type=Baseline Data Precision=8 bits Image Height=2670 pixels Image Width=4000 pixels Number of Components=3 Component 1=Y component: Quantization table 0, Sampling factors 1 horiz/1 vert Component 2=Cb component: Quantization table 1, Sampling factors 1 horiz/1 vert Component 3=Cr component: Quantization table 1, Sampling factors 1 horiz/1 vert Image Width=7360 pixels Image Height=4912 pixels Bits Per Sample=8 8 8 bits/component/pixel Photometric Interpretation=RGB Make=NIKON CORPORATION Model=NIKON D800E Orientation=Top, left side (Horizontal / normal) Samples Per Pixel=3 samples/pixel X Resolution=300 dots per inch Y Resolution=300 dots per inch Resolution Unit=Inch Software=Adobe Photoshop CC 2017 (Windows) Date/Time=2019:05:23 15:55:17 YCbCr Positioning=Datum point Sensitivity Type=Recommended Exposure Index Exposure Time=1/125 sec F-Number=f/25.0 Exposure Program=Manual control ISO Speed Ratings=100 Sensitivity Type=Recommended Exposure Index Exif Version=2.30 Date/Time Original=2014:05:21 15:38:57 Date/Time Digitized=2014:05:21 15:38:57 Components Configuration=YCbCr Compressed Bits Per Pixel=2 bits/pixel Shutter Speed Value=1/124 sec Aperture Value=f/25.0 Exposure Bias Value=0 EV Max Aperture Value=f/2.8 Metering Mode=Multi-segment White Balance=Unknown Flash=Flash did not fire, auto Focal Length=60 mm User Comment= Sub-Sec Time=00 Sub-Sec Time Original=00 Sub-Sec Time Digitized=00 FlashPix Version=1.00 Color Space=sRGB Exif Image Width=4000 pixels Exif Image Height=2670 pixels Sensing Method=One-chip color area sensor File Source=Digital Still Camera (DSC) Scene Type=Directly photographed image CFA Pattern=[Red,Green][Green,Blue] Custom Rendered=Normal process Exposure Mode=Manual exposure White Balance Mode=Manual white balance Digital Zoom Ratio=1 Focal Length 35=60 mm Scene Capture Type=Standard Gain Control=None Contrast=None Saturation=None Sharpness=None Subject Distance Range=Unknown Unknown tag (0xea1d)=0 Interoperability Index=Recommended Exif Interoperability Rules (ExifR98) Interoperability Version=1.00 GPS Version ID=2.300 Compression=JPEG (old-style) X Resolution=72 dots per inch Y Resolution=72 dots per inch Resolution Unit=Inch Thumbnail Offset=1186 bytes Thumbnail Length=5555 bytes XMP Value Count=29 Profile Size=3144 CMM Type=Lino Version=2.1.0 Class=Display Device Color space=RGB Profile Connection Space=XYZ Profile Date/Time=1998:02:09 06:49:00 Signature=acsp Primary Platform=Microsoft Corporation Device manufacturer=IEC Device model=sRGB XYZ values=0.964 1 0.825 Tag Count=17 Copyright=Copyright (c) 1998 Hewlett-Packard Company Profile Description=sRGB IEC61966-2.1 Media White Point=(0.9505, 1, 1.0891) Media Black Point=(0, 0, 0) Red Colorant=(0.4361, 0.2225, 0.0139) Green Colorant=(0.3851, 0.7169, 0.0971) Blue Colorant=(0.1431, 0.0606, 0.7141) Device Mfg Description=IEC http://www.iec.ch Device Model Description=IEC 61966-2.1 Default RGB colour space - sRGB Viewing Conditions Description=Reference Viewing Condition in IEC61966-2.1 Viewing Conditions=view (0x76696577): 36 bytes Luminance=(76.0365, 80, 87.1246) Measurement=1931 2° Observer, Backing (0, 0, 0), Geometry Unknown, Flare 1%, Illuminant D65 Technology=CRT Red TRC=0.0, 0.0000763, 0.0001526, 0.0002289, 0.0003052, 0.0003815, 0.0004578, 0.0005341, 0.0006104, 0.0006867, 0.000763, 0.0008392, 0.0009003, 0.0009766, 0.0010529, 0.0011292, 0.0012055, 0.0012818, 0.0013581, 0.0014343, 0.0015106, 0.0015869, 0.0016632, 0.0017395, 0.0018158, 0.0018921, 0.0019684, 0.0020447, 0.002121, 0.0021973, 0.0022736, 0.0023499, 0.0024262, 0.0025025, 0.0025788, 0.0026551, 0.0027161, 0.0027924, 0.0028687, 0.002945, 0.0030213, 0.0030976, 0.0031739, 0.0032502, 0.0033417, 0.003418, 0.0034943, 0.0035859, 0.0036622, 0.0037537, 0.00383, 0.0039216, 0.0040131, 0.0041047, 0.0041962, 0.0042878, 0.0043793, 0.0044709, 0.0045624, 0.0046693, 0.0047608, 0.0048524, 0.0049592, 0.005066, 0.0051575, 0.0052644, 0.0053712, 0.005478, 0.0055848, 0.0056916, 0.0057984, 0.0059052, 0.0060273, 0.0061341, 0.0062562, 0.006363, 0.0064851, 0.0066072, 0.0067292, 0.0068513, 0.0069734, 0.0070954, 0.0072175, 0.0073396, 0.0074617, 0.007599, 0.0077211, 0.0078584, 0.0079957, 0.0081178, 0.0082551, 0.0083925, 0.0085298, 0.0086671, 0.0088045, 0.008957, 0.0090944, 0.0092317, 0.0093843, 0.0095369, 0.0096742, 0.0098268, 0.0099794, 0.010132, 0.0102846, 0.0104372, 0.0105898, 0.0107576, 0.0109102, 0.0110628, 0.0112306, 0.0113985, 0.0115511, 0.0117189, 0.0118868, 0.0120546, 0.0122

MySQL并Tomcat优化记录

max_connections = 1000 # MySQL的最大连接数，如果服务器的并发连接请求量比较大，建议调高此值，以增加并行连接数量，当然这建立在机器能支撑的情况下，因为如果连接数越多， 介于MySQL会为每个连接提供连接缓冲区，就会开销越多的内存，所以要适当调整该值，不能盲目提高设值。可以过'conn%'通配符查看当前状态的连接数量，以定夺该值的大小。
